    To change the timecode type used by the system, 
    see 8.1.3, “Selecting a timecode type” .
    [8] MACHINE number indicators (1 
    through 6, E1, E2)
    This indicator shows the machine currently 
    selected for control with the transport keys. , using 
    the MACHINE
     key [31]. 1
     through 6
     refer to 
    DTRS units. E1
     and E2
     refer to VTRs, etc. which 
    may be connected to the RC-898. E1 is connected 
    to the parallel port, and E2 to the 9-pin RS-422 
    port
    [9] LOCK STATUS indicators
    These indicators show the current lock status of 
    the DTRS units as they chase to external synchro-
    nization sources. For units 2 through 6, the exter-
    nal synchronization master will typically be the 
    first DTRS unit (1) in the chain.
    There are four modes displayed by these 
    indicators:
    [10] OFFSET, PULL UP/DN, 
    CONFIDENCE, DELAY, TC REC, 
    VARI indicators
    These indicators are used to show the status of the 
    appropriate mode on the currently-selected unit. 
    The status is changed using the menus on the dis-
    play screen.
    In addition, changing the values from the front 
    panel of a DTRS unit connected to the RC-898 
    will change the status of this indicator, if the unit’s 
    number corresponds to the current MACHINE
     
    number [8].
    [11] LCD display screen
    This 20-character x 4-line backlit display screen is 
    used to show and set the different parameters 
    available with the RC-898.
    [12] Time Mode indicators
    Only one of these indicators will be lit at any one 
    time. They indicate the timecode reference (time-code; TC
    , or absolute time; ABS
    ) in use by the 
    currently-selected DTRS unit and shown on the 
    TAPE TIME
     indicator [13].
    The REL
     indicator, when lit, shows that the cur-
    rent time, relative to a user-defined reference 
    point, as explained in 6.3, “Setting a relative time 
    reference”, is currently being displayed.
    [13] TAPE TIME display
    This display shows the current tape time on the 
    currently-selected unit. The time reference is 
    shown by the indicators at [12].
    [14] MEMORY NO. display
    This 2-digit counter shows the location memory 
    which is currently in use (for storage, recall or 
    location).
    [15] LOCATE TIME/VALUE display
    This display shows the time of the location mem-
    ory currently referenced by the MEMORY NO.
     
    indicator [14] or entered using the numeric keypad 
    [16].
    It is also used to show time values which are set as 
    control parameters in various menu screens.
    [16] Numeric keypad
    The ten number keys are used for direct entry of 
    values for location memories, etc., to select loca-
    tion memories for store, recall, etc., or for the 
    entry of time values into LCD display menu 
    parameters. The +/–
     key is used to change a posi-
    tive to a negative value, or vice versa.
    The +/–
     key is also used with relative times, as 
    explained in the relative time setting section in see 
    6.3, “Setting a relative time reference”.
    [17] STR key
    This key is used to start the process for storing a 
    timecode value to a location memory. See 6.5.6, 
    “Storing the location in a memory” for details.
    [18] RCL key
    This key is used to start the process for recalling a 
    timecode value from a location memory. See 
    6.5.7, “Recalling a location memory” for full 
    details.
    [19] CANCEL key
    This key is used to cancel the selection of a loca-
    tion memory with the number keys, before storing 
    a time to it or recalling a time. It may also be used 
    to cancel the setting of a numerical value if it has 
    been wrongly entered.
    NOTE
    30 fps drop-frame is only supported by DA-98 units.

    [20] ENTER/LOAD key
    This key is used to confirm the entry of numerical 
    values of location times or memories or when 
    used with the SHIFT
     key [23], transfers the data 
    shown in the LOCATE TIME/VALUE
     display 
    [15] to the parameters being set in the display 
    screen.
    [21] PRESET key
    This key is used to assign specific software menus 
    to the function keys [22]. See 4, “Menu and basic 
    operations” for details of menu operations.
    [22] F1 through F10 function keys
    These keys are used with frequently-used menus, 
    so that one keypress will bring up these menus. 
    The keys may be “shifted” [23] to provide a sec-
    ond bank of 10 less frequently-used menu keys.
    [23] SHIFT key
    This key is used to provide a second bank of ten 
    function keys for quick access to frequently-used 
    menus. 
    It is also used with the UP
     and DOWN
     keys [25] 
    to use them as NEXT
     and PREVIOUS
     keys for 
    the selection of machines in the display screen 
    menus.
    It is also used in conjunction with the ENTER/
    LOAD
     key [20] to transfer entered values to the 
    parameters being set in the display screen.
    [24] ESCAPE key
    This key is used to move “up” through the menu 
    tree to the preceding menu screen.
    [25] Cursor keys
    The cursor keys are represented in this manual by 
    the words:
    • up keyUP
    • down keyDOWN
    •left keyLEFT
    • right keyRIGHT
    These keys are used to navigate through the menu 
    system and the parameters available.
    The UP
     and DOWN
     keys are also used with the 
    SHIFT
     key [23] to choose the connected unit on 
    which the menu operation will be performed 
    (when shifted, they are known as the NEXT
     and 
    PREVIOUS
     keys, repsectively). within each 
    screen. For details of menu operations, see 4, 
    “Menu and basic operations”.
    [26] SELECT key
    This key is used as an “enter” key, to select an 
    item or to confirm the entry of a value.
    [27] DATA INC/DEC key and indicator
    This key, with its integral indicator, is used to 
    change the function of the JOG
     dial [28] between 
    controlling the transport (indicator is unlit) and 
    incrementing or decrementing the values being 
    edited in the LOCATE TIME/VALUE
     display 
    [15] (indicator is lit).
    [28] JOG dial and SHUTTLE wheel
    These controls work with DTRS units and with 
    units connected to the EXT 2
     control port [43].
    They are used to simulate the “rock and roll” of an 
    open-reel tape deck, allowing precise positioning 
    of the controlled units. The indicators above the 
    controls show the current direction of the 
    medium’s movement.
    When the DATA INC/DEC
     indicator [27] is lit, 
    the JOG
     dial acts as a data editing control for the 
    least significant field of the value shown in the 
    LOCATE TIME/VALUE
     display [15].
    [29] CAPTURE key
    When this is pressed, the current time is displayed 
    on the LOCATE TIME/VALUE
     display [15] 
    where it may be edited and stored as a location 
    memory, or used for “one-shot” location purposes.
    [30] REPEAT key and indicator
    This key serves the same function as the REPEAT 
    key on the DTRS units, repeating playback 
    between the memory locations assigned for repeat 
    (see 6.6, “Repeating a section”).
    The integral indicator will light steadily when 
    repeat mode is selected and the current time is 
    between these two locations, and flash when 
    repeat mode is selected, and the current time is 
    outside these locations.
    [31] MACHINE key
    Pressing this key repeatedly will cycle the 
    machine number indicators [8]. The indicator 
    which is lit shows which machine will be con-
    trolled by the transport controls of the RC-898.
    [32] CHASE key
    Pressing this CHASE
     key together with the unit 
    number toggles the chase mode of the appropriate 
    unit.
    See 7.2.1, “Chasing to ABS sync” and 8.1.8, 
    “Chasing to external timecode” for further details. 
    						
    							Section 2.2 - Rear Panel
    2-5
    It is also possible to select “Machine 0” (only with 
    this CHASE
     key). This will control the second 
    (first slave) DTRS unit, and toggle the chase status 
    of this unit, with all other slave units in the chain 
    then changing to reflect the chase status of this 
    first slave unit.
    [33] AUTO PLAY key and indicator
    This key with its integral indicator works with 
    DTRS units. It allows the units to start playing 
    back automatically when a location point is 
    reached.
    [34] PRRL key and indicator
    This key with its integral indicator works with 
    DTRS units. It is used to locate the tape to the 
    punch-in position, minus the pre-roll time set for 
    punch operations (see 6.7.5, “Setting pre-roll and 
    post-roll times”).
    For instance, if the punch pre-roll value is set to 5 
    seconds, and the punch-in point is “00:55:12:12”, 
    the unit will finish locating at 00:55:07:12.
    [35] RHSL key and indicator
    This key allows you to rehearse auto-punch opera-
    tions on the units connected to the RC-898. For 
    full details, see 6.7, “Punch operations”.
    [36] AUTO PUNCH key and indicator
    This key allows you to perform auto-punch opera-
    tions on the units connected to the RC-898. For 
    full details, see 6.7, “Punch operations”.
    [37] MARK IN key
    This key allows you to set and check the punch-in 
    point for automatic punch operations. For full 
    details of how to use this key, see 6.7.1, “Setting 
    punch points”.
    [38] MARK OUT key
    This key allows you to set and check the punch-
    out point for automatic punch operations. For full 
    details of how to use this key, see 6.7.1, “Setting 
    punch points”.
    [39] CUE STR key
    This key is used to capture a series of location 
    points (a cue list) “on the fly”. Successive presses of this key will store the current position to a loca-
    tion memory, and automatically increment the 
    location memory number, ready for the next store 
    operation. The memories can later be “fine-tuned” 
    using the jog dial [28] in the appropriate mode.
    [40] Transport controls
    These transport controls duplicate those available 
    on DTRS units. They may also be used to control 
    units connected to the E1 (parallel) and E2 (9-pin 
    serial) ports when the appropriate machine is 
    selected ([8] and [31]).
    [41] LOC key
    This key provides one-touch operation to allow 
    location to the memory position shown on the 
    LOCATE TIME/VALUE
     display [15]. If a loca-
    tion pre-roll time has been set (see 6.5.1, “Setting 
    the location pre-roll value”) the pre-roll offset will 
    be subtracted from the location value, and the 
    location will be to that new calculated value.
    2.2 Rear Panel
    [42] EXT 1 – parallel and GPI port
    This port provides parallel control and tally sig-
    nals or GPI control for event control, which may 
    be triggered from a small “cue list” in the RC-898. 
    The pinout for this 15-pin ’D’-sub connector is 
    given in 3.2, “Connections (parallel units)”. You 
    will need to make your own cable, referring to the 
    the table above, and to the equivalent table in the 
    manual of the other equipment if you wish to con-
    trol an external unit through parallel control, or if 
    you wish to send GPI events from the RC-898.
    [43] EXT 2 - serial port
    This 9-pin ‘D’-sub connector is used for the con-
    trol of devices implementing the Sony P2 proto-
    col. A cable designed for P2 connections may be 
    used with this port.
    [44] REMOTE OUT connector
    This connector is used for the control of the DTRS 
    units. It should be connected to the REMOTE IN/
    SYNC IN of the first DTRS unit in the chain.
    Only use a TASCAM cable, as supplied with the 
    RC-898, to make this connection. If your DTRS 
    units are at a greater distance than the cable pro-
    vided (e.g. your machine room is some distance 
    from your control room), consult your TASCAM 
    dealer for details of the availability of longer 
    DTRS control cables.
    NOTE
    The two keys above do not work in the same way as the 
    rehearsal and auto punch keys on DTRS units. Even if you 
    are an experienced user of DTRS equipment, we recom-
    mend that you read 6.7, “Punch operations” to get a full 
    understanding of punch operations when using the RC-898 
    to control recording operations.

    2-6 
    [45] DIP switches (1 & 2)
    The two DIP switches are both on when in the 
    down position. As shipped from the factory, 
    switch 1 is off (up) and switch 2 is on (dow), and 
    you probably will not need to change them.
    However, when a passive device is connected to 
    the EXT 1
     connector and power is not provided 
    from the device to the tally supply pin, this switch 
    1 (TALLY POWER
    ) should be set to the on 
    (down) position, allowing the RC-898 to use its 
    own power for this purpose.
    Switch 2, GND LIFT
     (ground lift) controls the 
    isolation of the ground of the RC-848/DTRS sys-
    tem from the ground of devices attached to the 
    EXT 1
     and EXT 2
     ports. Usually this switch is in 
    the on (down) position, but you may need to turn it 
    off (up) if your system suffers from hum prob-
    lems. However, a full discussion of ground loops 
    and their associated problems is outside the scope 
    of this manual, and we recommend that you con-
    sult one of the many reference works on this sub-
    ject if necessary.
    [46] Contrast
    This control alters the contrast on the backlit LCD 
    display screen [11]. Use it to set the screen so that 
    it is easily visible from your preferred viewing 
    angle. 
    						
    							Section 3.1 - Connection to DTRS units
    3-1
    3 – Connections
    This section describes not only the connection of 
    the RC-898 to other equipment, but also provides 
    some information on setting up a digital audio 
    system using the RC-898.
    3.1 Connection to DTRS units
    The RC-898 and DTRS units form a “daisy-
    chain”, with the RC-898 being at the head, and the 
    “tail” unit being terminated with the terminator 
    supplied with the RC-898. 
    Use the suppled cable to connect the RC-898 to 
    the REMOTE IN/SYNC IN of the first DTRS 
    unit, and a PW-88S cable to connect the SYNC 
    OUT of the first unit to the REMOTE IN/SYNC 
    IN of the next unit, and so on, until the terminator is connected to the SYNC OUT of the last unit in 
    the chain.
    The RC-898’s REC FUNCTION
     and INPUT 
    MONITOR
     keys 1
     through 8
     now control the first 
    unit, Keys 9
     through 16
     control the next unit in 
    the chain, and so on (regardless of the actual 
    Machine IDs of the units).
    Tighten the screws holding the cable connector to 
    the RC-898 and to the DTRS unit. This will pre-
    vent accidental disconnection of the RC-898 in the 
    middle of a session.
    No power connection is needed for the RC-898. 
    All power for the operation of the RC-898 is sup-
    plied by the first DTRS unit.
    3.1.1 Machine IDs
    Set the machine IDs of the DTRS units so that the 
    IDs run in a sequence from the unit at the “head” 
    of the chain, closest to the RC-898 (lowest possi-
    ble ID) to the “tail” unit (highest ID). There 
    should be no gaps in this sequence.
    A DA-88 uses a rotary switch to set the ID and 
    uses 0 as the lowest ID, and a DA-38 or DA-98 
    uses software to make this setting, and uses 1 as 
    WARNING
    All connections to the RC-898 should be made with the 
    power to all units turned off. If this is not done, the opera-
    tion of the units may become unstable, and damage may 
    possibly occur.
    NOTE
    When you connect a number of DTRS units which are of 
    different types, including DA-98s, the DA-98 units should 
    be at the head of the chain immediately following the RC-
    898. Any DA-38 and DA-88 units should then be connected 
    following the DA-98s. If there is more than one DA-98 in 
    the chain, they should be connected together, before the DA-
    38s and DA-88s. The order of the DA-38 and DA-88 units is 
    not important.
    If a DTRS unit other than a DA-98 is used as a master unit, 
    the automatic Output TC Source function and Timecode 
    Offset functions of the DA-98 may not work correctly (see 
    the DA-98 Owner’s Manual, 10.5 and 13.2). In additoin, 
    remote control operation may not work correctly.
    If the DTRS units are DA-88s and DA-38s only, they may 
    be connected in any order. 
    However, if you are operating a mixed set of DA-38s, and 
    DA-88s fitted with the SY-88 synchronizer board, we sug-
    gest that the SY-88-equipped DA-88 should follow the RC-
    898, allowing it to serve as a timecode slave, and a DTRS 
    chase master for the DA-38s.
    WARNING
    Turn off power to all units when making connections. If you 
    do not do this, there is a possibility that the RC-898 will 
    malfunction or even be damaged.
    WARNING
    Use only TASCAM cables to connect the RC-898 to the first 
    DTRS unit, and to connect the DTRS units to each other. If 
    the use of cables other than TASCAM cables causes or 
    results in damage to the units, the warranty is voided.
    NOTE
    The TASCAM TM-D8000 digital mixing console also 
    allows the control of DTRS units. However, it is not possi-
    ble to use a TM-D8000 and RC-898 for control of DTRS 
    units in the same setup. Naturally, however, a TM-D8000 
    console can be used to mix the audio to and from DTRS 
    units controlled by an RC-898 unit.

    the lowest ID. Refer to the units’ manuals for full 
    details of setting the ID.
    3.2 Connections (parallel 
    units)
    The RC-898 allows transport control of a unit con-
    nected to the EXT 1
     parallel port. Before making 
    this connection, check the specifications of the 
    other unit to ensure that the control pins available 
    match those provided by the RC-898, as shown 
    below in 3.2.2, “Parallel control/GPI pinout”.
    If a passive unit that does not supply power to the 
    tally supply pin (8) is being used, switch 1 
    (TALLY POWER
    ) of the RC-898 [45] must be set 
    on (down) to allow the RC-898 to provide this 
    power.
    3.2.1 Connections (GPI event units)
    The EXT 1
     parallel port may also be used for the 
    purpose of controlling up to five GPI event-con-
    trolled devices.
    The way in which these devices may be triggered 
    from the RC-898 is explained in 9.2, “Controlling 
    GPI devices”.
    3.2.2 Parallel control/GPI pinout
    The following table gives the pin assignments for 
    the parallel/GPI connector (EXT 1
    ). GPI connec-
    tions are shown in square brackets:
    3.3 Connections (RS-422 
    units)
    The RC-898 allows control of a unit implementing 
    the Sony P2 protocol. This connection is made 
    through the EXT 2
     serial port [43], using a serial 
    cable designed for this purpose. The pinout for 
    this connector is as follows:
    Make the connection using a cable designed for 
    RS-422 connection (check the pinout of your P2 
    device before making the connection). This 
    machine may now be controlled by the RC-898 
    when the E2 MACHINE
     indicator [8] is lit.
    3.4 A note on system clocks
    When working with many digital audio units, all 
    these units must be fed from the same clock 
    source (either word or video). If this is not done, 
    there is a risk that speakers, etc. may be damaged.
    Note that this clock master is entirely different 
    from the timecode master in a studio setup. It is 
    perfectly possible for a clock slave to be a time-
    code master and vice versa.

    NOTE
    When you set the machine IDs, you can set the ID of any 
    machine first, but we recommend doing this in a standard 
    sequence, working from the head of the chain to the tail.
    NOTE
    The RC-898 provides only transport control for a unit con-
    nected to the parallel port. Functions such as track arming, 
    etc. are not possible when using the EXT 1
     parallel port.

    3.5 Memory and batteries
    As you have noticed, the RC-898 requires no 
    power supply of its own, drawing its power from 
    the DTRS units to which it is connected.
    Location memories and configuration settings are 
    stored using a battery backup system. The battery 
    should provide power for several years of use. 
    When the battery eventually degrades to the point 
    where it cannot provide enough power to retain 
    settings, the message 
    Memory Error will 
    be shown on the diaply screen (this can be 
    removed by pressing the ESCAPE
     key). 
    When this message appears, all memories (loca-
    tion memories and configuration settings) are 
    cleared and reset to the default settings.
    If you see this message, contact your TASCAM 
    dealer for details of battery replacement. Do not 
    attempt to replace the battery by yourself.

    4 – Menu and basic operations
    The RC-898 sets parameters on the connnected 
    units using a menu system, with the parameters 
    and their values displayed on the LCD display 
    screen and selected and entered using cursor and 
    data entry keys.
    4.1 Navigation
    The menus are arranged hierarchically, from a top 
    (master) menu, through to individual parameters. 
    The master “top” menu appears like this:
    The cursor is represented here by the 
    > symbol.
    Use the LEFT
     and RIGHT
     keys to move the cur-
    sor along a row, and the UP
     and DOWN
     keys to 
    move it between rows.
    As the cursor moves over the menu group num-
    bers, the bottom line of the screen will change to 
    show an abbreviated summary of the contents of 
    the menu group. In the example above, the con-
    tents of the 
    0 menu group are: track delay, track 
    copy settings, varispeed and the location pre-roll 
    setting.
    When the cursor is over the menu group which 
    you wish to enter, press the SELECT
     key to enter 
    the menu group (menu group 0 is shown here):
    Again, the bottom line of the display shows an 
    abbreviated version of some or all of the settings 
    made in the menu to which the cursor points.
    When in a menu group, use the cursor keys to 
    move between options, and press SELECT
     when 
    the cursor is to the left of the menu you wish to enter. For the purposed of this example, we will 
    examine the 
    Vari Spd menu.
    In this menu, there are two editable fields, as you 
    will see if you move the cursor with the LEFT
     and 
    RIGHT
     cursor keys. The cursor changes so that 
    the field which is currently to be edited is high-
    lighted by an underline cursor.
    The first editable field is the 
    Fix field, which 
    may be changed between the values of 
    Fix and 
    Vari. The second field is the numerical field 
    which sets the amount of the varispeed as a per-
    centage of normal speed. The values of both fields 
    are set with the UP
     and DOWN
     cursor keys.
    As soon as a value is changed, it is set. There is no 
    need to press any key to confirm the entry.
    To return to a level above the current level, press 
    the ESCAPE
     key. You can continue pressing the 
    ESCAPE
     key until the top menu is reached.
    4.1.1 Invalid operations
    Some operations are only possible on certain 
    models of DTRS recorder. For instance, timecode 
    functions are only available on the DA-98 and 
    DA-88 units equipped with the SY-88 board, and 
    dithering is only possible with DA-38 and DA-98 
    units. If you attempt to perform an operation on a 
    unit where this operation is impossible, the mes-
    sage 
    Not available! will be shown on 
    the display screen to let you know that you cannot 
    perform this operation on the connected DTRS 
    unit.
    Another kind of invalid operation is when a DTRS 
    unit can perform a certain operation, but the 
    selected operation cannot be performed under the 
    current set of conditions (e.g. TDIF word length 
    cannot be set while analog inputs are selected). In 
    these cases, the word 
    Inoperable will be 
    shown on the display.

    							Section 4.2 - Data entry  
    4-2 
    4.2 Data entry
    Typically, the UP
     and DOWN
     keys are used to set 
    the values in the display screen menus. However, 
    there are one or two additional features regarding 
    data entry which are explained here.
    4.2.1 Resetting values to zero
    In the case of large numerical values, it is some-
    times tedious to keep pressing the cursor keys 
    until the value returns to zero. 
    Accordingly, to reset a value to zero:
    1) Press and hold down either the UP
     or DOWN
     
    key.
    2) While holding down this key, press the other 
    (i.e. DOWN
     if you are holding the UP
     key, and 
    vice versa).
    4.2.2 Fast setting of values
    In addition to being able to reset large values to 
    zero, it also sometimes necessary to input large 
    values. This can be done easily in the following 
    way:
    1) Press and hold down the UP
     or DOWN
     key (as 
    appropriate).
    2) While holding down this key, press and hold 
    down the SELECT
     key. As long as this key is 
    held down, the values will change quicker than 
    if this UP
     or DOWN
     key on its own is held 
    down.
    4.2.3 Setting values using the VALUE 
    display
    As well as using the LCD display, the LOCATE 
    TIME/VALUE
     LED display [15] and numeric 
    keypad [16] may be used for entry of time values 
    into certain parameters which are set through the 
    menu system.
    The machine offset value from menu group 3, 
    which is expressed in hours, minutes, seconds and 
    frames, is a useful example of this operation.
    1) In the top level menu, move the cursor to menu 
    group 3 and press SELECT
    :2) With the cursor as shown (next to the Machine 
    Offset menu item), press SELECT
     again:
    3) Use the numeric keypad to enter the offset time 
    (use the +/–
     key to change between positive and 
    negative offset).
    The values entered using the keypad will appear in 
    the LOCATE TIME/VALUE
     display [15], and “fill 
    up” from the right. For instance, if the time to be 
    entered is 01:23:07:10, the following keys should 
    be pressed:
    The display will flash while the numbers are being 
    entered, to show that the value has not yet been 
    confirmed.
    Negative values are shown on the LOCATE TIME/
    VA L U E
     display by a period after the last “frames” 
    digit of the display.
    4) Press and hold down the SHIFT
     key [23] and 
    then press the ENTER/LOAD
     key [20].
    If the value is a valid one (i.e. you do not attempt 
    to enter 71 frames in a second, etc.), it will be 
    transferred from the LED display, which will stop 
    flashing, to the LCD display screen:
    Invalid values will be rounded down to the nearest 
    valid value (e.g. a value of 78 seconds will be 
    rounded down to 59 seconds).
