OPERATING FEATURES

“TOT” reset time
The transceiver has “TOT” reset timer.  This timer is the
minimum wait time allowed during a transmission that will
reset the “TOT” count.
“TOT” reset time causes the “TOT” to continue even
after PTT is released unless the “TOT” reset timer has ex-
pired.

OST (Operator Selectable Tone)
The transceiver is capable to have “OST” function and 16
tone pair (QT/DQT) with max 10-digit name for each tone
pair.

“OST” back up
The transceiver is programmable the selected “OST”
code is memorized or not.  If you set to Disable (no memo-
rized), the “OST” function always starts at “off”.

Direct “OST”
It is possible to call “OST” number directory using key-
pad.  In this case, keypad is used for “OST”, then auto
“PTT” store and send functions by keypad are not usable.

Clear to transpond
The transceiver waits the transpond of 2-tone /DTMF if
channel is busy until channel open.  This feature prevents
the interference to other party.
5. Option Signalling
5-1. DTMF/2-Tone
Built-in DTMF decoder is available for option signalling.
Built-in 2-tone decoder is available for option signalling.
It is possible to use individual call, group call, D.B.D.
(Dead Beat Disable).  D.B.D. is used with DTMF only.
If the option signalling matches, a predetermined action
will occur.
If option signalling matches on a group/channel which is
set up with option signalling, the option signalling indicator
(
*) will flash and option signalling will be released.  The
transpond or alert tone will sound.
If the selective call alert LED is set up, the orange LED
will flash.
While option signalling matches (or if option signalling is
deactivated when you are transmitting), you can mute or
unmute ID/QT/DQT/Carrier.

AND/OR
You can select AND or OR for option signalling match
conditions.
Alert/Transpond
AND QT/DQT/ID+DTMF (2-tone); Option matches = Action
OR QT/DQT/ID+DTMF (2-tone); Option matches = Action
AF mute open
AND QT/DQT/ID+DTMF (2-tone); Option matches = Action
OR QT/DQT/ID; Signalling only matches = Action
With OR set up, alert/transpond will not function with
only DTMF (Trunking format).
With OR set up, AF mute will not release when only
DTMF matches.
With a conventional channel not set up with QT or DQT,
only the carrier is considered when signalling matches.

Auto Reset
If option signalling matches a group set up with option
signalling, option signalling is released.  After matching op-
tion signalling, option signalling will temporarily reset auto-
matically.

Dead Beat Disable
If the D.B.D. code matches, a predetermined action will
occur.  Whether option signalling is activated or not, when
D.B.D. matches on any channel, the transceiver will become
TX inhibited or TX/RX inhibited.  While D.B.D. is active, if the
D.B.D. code + “#” code is received, D.B.D. will disactivate.
When D.B.D. matches, transpond will function.  Alert will
not be output, and option signalling match icon will not ap-
pear.
5-2. MSK
Built-in MSK (FleetSync™ : Fleet-ID) decoder is available
for option signalling.  When the group ID/Carrier matches,
squelch remains muted while the station waits for reception
of proper MSK signal.  When MSK signal matches, squelch
unmutes.

 AND/OR
AND : QT/DQT/ID + MSK to unmute.  MSK matches =
alert tone
OR : QT/DQT/ID to unmute.  MSK matches = alert tone
6.Alphanumeric Two-way Paging Function
(FleetSync™)

General
The Alphanumeric Two-way Paging Function
(FleetSync™) is a KENWOOD proprietary protocol.  It en-
ables a variety of paging functions.

ID Construction
A radio unit ID is defined by a combination of 3-digit Fleet
and 4-digit ID numbers.  Each radio unit must be assigned its
own Fleet and ID numbers.

PTT ID
A pre-programmed unique ID (own) can be sent at the
beginning of transmission and/or the end of transmission to
identify which radio unit is on air.
When selecting (sel) for MSK ID, the radio calls the spe-
cific Fleet user the same as selective call. 
						

							12
TK-780/ H

Selective Call (SELCALL)
This is a voice call to a particular individual or group of
stations.
•Example of call types;
[100][ALL ] : 
All the units whose fleet number is “100” are called.
[100][1000] : 
The unit, whose the fleet number is “100” and ID num-
ber is “1000”, is called.
[ALL][ALL ] : 
All the units are called.
[ALL][1000] : 
All ID “1000” are called regardless of their fleet number.
•Unit ID encode block
Encode ID Block can be set to limit manual dial ID.  The
radio unit will not accept an ID other than these IDs which
are entered from the keypad.  If Inter-fleet Call is enabled,
block ID setting affects  each fleet group.

Status Message
Using a 2-digit number, you can send and receive a Sta-
tus message which may be decided in your talk group.  Each
Status may be displayed with 16 alphanumeric characters if
programmed in the radio.  A maximum of 9 received mes-
sages can be stored in the stack memory, and it can be re-
viewed after reception.  If the message memory becomes
full, the oldest one will be erased.  The stack memory will be
cleared by turning radio power off.
•Status 80~99 (Special)
Status numbers from 80 to 99 are reserved for special
purposes.  Entering these statuses from the DTMF keypad
can be inhibited.
Please notice that the following status numbers are used
for special purposes;
80~87 : Reserved for future use.
88 : Terminates to emergency mode.
89 : Request for horn alert.
90 : Remote stun on.  Disable the received radio unit’s
TX.
91 : Remote stun on.  Disable the received radio unit’s
TX/RX.
92 : Cancel remote stun.  Enable the received radio unit’s
TX/RX.
93 : Acknowledgement status sent when the radio unit is
in stun mode (TX disabled).
94 : Acknowledgement status sent when the radio unit is
in stun mode (TX/RX disabled).
95~97 : Reserved for future use.
98 : Man down emergency status (For portable).
99 : Emergency status.
Note : Remote stun works with DTMF D.B.D. function also.
•Automatic status response
If you pre-select a status number and leave the radio in
the Status Mode, it can automatically respond with the se-
lected status number upon request from the base station.
(The request function is initiated by serial control on the
base station (Optional).)

Short Messase (Optional)
A maximum of 48 characters can be sent (External equip-
ment is required).  Received Short Messages will be dis-
played in the same manner as a Status Message.  A maxi-
mum of 4 received messages can be stored in the stack
memory.  In the Stack Mode, 3-digit LCD indicates the re-
ceived Short Message as “M01”~”M04".

Long Message (Optional)
A maximum of 1024 characters can be sent (External
equipment is required).  Received Long Message will not be
displayed or stacked in the radio memory but is output
through the COM (Data) port.

Emergency Function
Emergency status 99 will be sent at the beginning of
each emergency transmission.
•Emergency status response
Either “Horn” or “Alert” can be selected for the called
radio unit’s response to reception of status 99 which is used
as an emergency status.

Other Functions
•Manual dial
Fleet, ID and Status numbers can be entered from DTMF
keypad. (DTMF microphopne is required.)
•FleetSync™ baud rate
MSK data baud rate setting.  The same rate must be set
as a communication partner.
1200bps :
Data communication is made in 1200bps.  The communi-
cation area is much wider than 2400bps.  Recommended
for repeater operation.
2400bps :
Data communication is made in 2400bps.  The communi-
cation area is narrower  than 1200bps, but it will decrease
the data traffic.  Data rate 2400bps may not work prop-
erly depending on the repeater’s characteristic.
•Message mode timer
Message Mode Timer is a delay timer returning from
message/stack mode to Normal mode.
•Status/short/long message on data group/channel
Status/Short/Long Message transmission is made
whether on the Data System/Group in trunking format and
on the Data Group/Channel in conventional format.

Any selected sentence can be output through the radio
serial port (COM1 or COM0).1) MAP HEADER NMEA1 ($GPGGA), NMEA2 ($GPGLL),
NMEA3 ($GPRMC)
NMEA-0183 standard command.  This should be set ac-
cording to your PC application.
2) MAP HEADER KW1 ($PKLDS)
This is a Kenwood original sentence which consists of
“$GPGLL + Fleet + ID + Status”.  This item should be set
according to your PC application.
3) MAP HEADER KW2 ($PKLID)
This is a Kenwood original sentence which consists of
“Fleet + ID”.  This should be set according to your PC
application.

Parameters
•GTC count
Number of Go To data Channel messages to be sent be-
fore transmitting a data message if it is being made on Data
System/ Group.  If a radio unit receives a GTC message, it
will move to the Data System/Group of the current system.
Increase this item to make sure the called radio unit moves
to the Data System/Group in trunking format and the Data
Group/Channel in conventional format.
•Random access (Contention)
When a channel (or all the repeater channels for Trunking
mode) is busy, radio unit will not transmit (depending on its
Busy Channel Lockout setting in conventional mode).  As
soon as a channel is cleared, some transmissions may
crash.  Random access is used to avoid this by employing a
random transmission sequence.
•Number of retries
Number of Retries is the maximum number of retry
transmission when no acknowledgement is received in the
Maximum ACK Wait Time.  Increase this item to improve
data communication reliability.
•TX busy wait time
TX Busy Wait Time is the maximum amount of time be-
fore giving up the data transmission when the channel (or all
the repeater channels for Trunking mode) is busy.  Also, this
timer affects if it expires during Random Access period.
•Maximum ACK wait time
Maximum ACK Wait Time is the maximum amount of
time to wait for an acknowledgement from the called radio
unit. It is used as an interval time of retries.  It must be set
greater than the ACK Delay Time of the called radio unit.
OPERATING FEATURES

TK-780/ H
•ACK delay time
ACK Delay Time is the amount of time from the end of
receiving a data to the beginning of sending an
acknowledgement.  It should be adjusted as the repeater’s
hang-up delay time.  Also, it must be set less than the Maxi-
mum ACK Wait Time of the calling radio unit.
•TX delay time (RX capture)
TX Delay Time is the amount of unmodulated transmis-
sion to let the called unit stop scanning or exit its battery
save mode.  It is used only when starting a data communica-
tion sequence.
•Data TX modulation delay time
Data TX Modulation Delay Time is the amount of time
from the beginning of transmission to the beginning of a
data modulation.  It is used every time  data is transmitted.
It must be set to more than 300ms if data communication is
made in Trunking Mode.

5. PC Mode
5-1. Preface
The TK-780/780H transceiver is programmed by using a
personal computer, programming interface (KPG-46) and
programming software (KPG-49D).
The programming software can be used with an IBM PC
or compatible.  Figure 1 shows the setup of an IBM PC for
programming.
5-2. Connection Procedure
1. Connect the TK-780/780H to the personal computer with
the interface cable.
2. When the Power switch on, user mode can be entered
immediately.  When PC sends command the radio enter
PC mode, and “PROGRAM” is displayed on the LCD.
When data transmitting from transceiver, the red LED is
blinking.
When data receiving to transceiver, the green LED is
blinking.
Notes :
• The data stored in the personal computer must match
model type, when it is written into the flash memory.
• Change the TK-780/780H to PC mode, then attach the
interface cable.
5-3. KPG-46 Description
   (PC programming interface cable : Option)
The KPG-46 is required to interface the TK-780/780H to
the computer.  It has a circuit in its D-subconnector (25-pin)
case that converts the RS-232C logic level to the TTL level.
The KPG-46 connects the modular microphone jack of
the TK-780/780H to the computers RS-232C serial port.
5-4. Programming Software Description
The KPG-49D programming disk is supplied in 3-1/2" disk
format.  The software on this disk allows a user to program
TK-780/780H radio via programming interface cable (KPG-
46).

5-5. Programming With IBM PC
If data is transferred to the transceiver from an IBM PC
with the KPG-49D, the destination data (basic radio informa-
tion) for each set can be modified.  Normally, it is not neces-
sary to modify the destination data because their values are
determined automatically when the frequency range (fre-
quency type) is set.
The values should be modified only if necessary.
Data can be programmed into the flash memory in RS-
232C format via the modular microphone jack.
KPG-49D instruction manual parts No. : B62-1096-XX.

Notes :
• To start the Firmware Programmer from KPG-49D, the
FPRO path must be set up by KPG-49D setup.
• This mode cannot be entered if the Firmware program-
ming mode is set to Disable in the Programming soft-
ware (KPG-49D).
• When programming the firmware, it is recommend to
copy the data from the floppy disk to your hard disk be-
fore update the radio firmware.
Directly copying from the floppy disk to the radio may not
work because the access speed is too slow.
6-4. Function
1. If you press the [MON] switch while “PROG 57600” is
displayed, the checksum is displayed.  If you press the
[MON] switch again while the checksum is displayed,
“PROG 57600” is redisplayed.
2. If you press the [D] switch while “PROG 57600” is dis-
played, the display changes to “PROG 19200” to indicate
that the write speed is low speed (19200 bps).  If you
press the [D] switch again while “PROG 19200” is dis-
played, the display changes to “PROG 38400”, and the
write speed becomes the middle speed (38400 bps).  If
you press the [D] switch again while “PROG 38400” is
displayed, the display returns to “PROG 57600”.
Note :
Normally, write in the high-speed mode.
7. Clone Mode
Programming data can be transferred from one radio to
another by connecting them via their modular microphone
jacks.  The operation is as follows (the transmit radio is the
master and the receive radio is a slave).
1. Turn the master TK-780/780H power ON with the [C] key
held down.  If the password is set to the TK-780/780H,
the TK-780/780H displays “CLONE LOCK”.  If the pass-
word is not set, the TK-780/780H displays “CLONE
MODE”.
2. When “CLONE LOCK” is displayed, only the [System up/
down] key (Trunking format), the [Group up/down] key
(Conventional format) and [SCN], and [0] to [9] keys can
be accepted.  When you enter the correct password, and
“CLONE MODE” is displayed, the TK-780/780H can be
used as the cloning master.  The following describes how
to enter the password.
3. How to enter the password with the microphone keypad.
If you press a key while “CLONE LOCK” is displayed, the
number that was pressed is displayed on the TK-780/
780H.  Each press of the key shifts the display in order to
the left.  When you enter the password and press the
[SCN] key, “CLONE MODE” is displayed if the entered
password is correct.  If the password is incorrect,
“CLONE LOCK” is redisplayed.How to enter the password with the [System up/down]
key (Trunking format), the [Group up/down] key (Conven-
tional format);
If the [System up/down] key (Trunking format), the
[Group up/down] key (Conventional format) is pressed
while “CLONE LOCK” is displayed, numbers (0 to 9) are
displayed flashing.  When you press the [SCN] key, the
currently selected number is determined, and the display
shifts to the left.  If you press the [SCN] key after entering
the password in this procedure, “CLONE MODE” is dis-
played if the entered password is correct.  If the pass-
word is incorrect, “CLONE LOCK” is redisplayed.
4. Power on the slave TK-780/780H.
5. Connect the cloning cable (No. E30-3382-05) to the
modular microphone jacks on the master and slave.
6. Press the [S] key on the master while the master displays
“CLONE MODE”.  The data of the master is sent to the
slave.  While the slave is receiving the data, “PRO-
GRAM” is displayed.  When cloning of data is completed,
the mater displays “END”, and the slave automatically
operates in the User mode.  The slave can then be oper-
ated by the same program as the master.
7. The other slave can be continuously cloned.  When the
[S] key on the master is pressed while the master dis-
plays “END”, the master displays “CLONE MODE”.
Carry out the operation in step 4 to 6.
Note :
Only the same models can be cloned together.
