DIP Switch Options
The RPCI-DI, PDIU-DI and the PDIU-DS each have a four-control DIP switch which can be 
configured for signaling options. The switch is located on the bottom of the PDIU-DI, and on the 
back panel of the PDIU-DS (see Figure 10-33).
SW1-1
Normally, this switch is set ON to disconnect devices from RPCIs or DIUs automatically. The 
connection is maintained if data is exchanged between the device and the RPCI or DIU within 
eight to nine minute intervals. If SW1-1 is OFF on the called and calling DIU, data calls will 
remain connected until released manually.
SW1-2
This switch is placed in the ON position when the RPCI-DI or PDIU-DI (or PDIU-DS configured 
like a DCE) must hold DCD and DSR ON continuously. If SW1-2 is OFF, DSR follows DTR and 
DCD will be ON only when the DIU is connected on a data call to another DIU. SW1-2 should be 
OFF on a RPCI DIU when it is connected to a personal computer that uses a communications 
software program to establish data calls with AT commands; and whenever PDIU-DS is connected 
to a modem.
SW1-3
The RPCI-DI or PDIU-DI (or PDIU-DS configured as a DCE) sends the Ring Indicate (RI) signal 
to the computer to tell the computer (DTE) that the RPCI or PDIU is receiving an incoming call. 
SW1-3 should be ON for the DIU to send RI steady, and OFF to send at one second ON/three 
seconds OFF intervals.
SW1-4
This switch is placed in the ON position if the computer does not output the RTS signal or when 
connected to a modem that tracks the DCD signal (modem set with AT&C1). Sometimes, the DTE 
device may use RTS/CTS for Ready/Busy flow control, in these cases SW1-4 should be OFF. 
In this case the DCD signal of the calling DTE is used as the RTS lead of the called DTE and the 
DCD signal of the called DTE is used as the RTS signal of the other DTE. In this case a signal 
which stops the DTE from transmitting data (usually the CTS lead) should be cross-connected to 
the RPCI’s or DIU’s DCD signal. Consult the DTE device or application software documentation 
to determine which type of flow control is required. If the DIU-DS is connected to a modem that 
tracks carrier detect (AT&C1) SW1-4 should be ON.

Peripheral Installation
RPCI-DI and PDIU-DI to PC Installation 
The RPCI-DI and PDIU-DI always functions as a DCE device; it transmits data on the Receive 
Data lead (RD) and receives data on the Transmit Data lead (TD). Most personal computers 
function as a DTE device; PCs transmit data on the TD lead and receive data on the RD lead.
NoteThe RPCI-DI or PDIU-DI can connect to a DCE computer or any other DCE-type device 
using a specially configured RS-232 cable or adapter; but this application is rarely 
required. 
ä
To install the RPCI-DI or PDIU-DI to a DTE device, PC, or ASCII terminal
1. Install the digital telephone that is to be equipped with RPCI-DI or PDIU-DI per the 
instructions in Chapter 9 – Station Apparatus and the drawing in Chapter 8 – DK40i/DK424 
Universal Slot PCB Wiring.
2. Install the RPCI-DI or PDIU-DI under the digital telephone per the instructions in Chapter 9 – 
Station Apparatus.
NoteThe RPCI-DI or PDIU-DI always operates as a DCE device; therefore, unlike the PDIU-
DS, it has no internal jumpers. 
3. Connect the appropriate RS-232 cable between the RPCI-DI or PDIU-DI’s DB-25 female 
connector and the PC’s appropriate asynchronous serial communications port connector 
(COM port).
Important!Check the PC manufacturer’s serial communication port interface documentation 
for correct RS-232 pin requirements; requirements vary with each manufacturer. 
The number of EIA RS-232 signals required (8, 9, or 10 wires) depends on the 
application. When EIA signal requirements are not known, connect the 10 EIA 
signals listed in “EIA Interface Leads (Signals)” on Page 10-50. Figures 10-33 and 
10-31 provide diagrams for connecting RS-232 cables between PDIU-DIs and PCs/
Toshiba portables.
4. Set the RPCI-DI or PDIU-DI DIP switch (SW1-1~4) for the desired application. See Figure 
10-33, “RPCI-DI, PDIU-DI, PDIU-DS SW1 DIP Switch Information”.
RPCI-DI and PDIU-DI Programming

©LED 01: Should always be ON for RPCI-DI and PDIU-DI ports. 
©LED 02: Should be ON for RPCI-DI or PDIU-DI ports, unless the PC user will never uses 
RPCI or DIU AT commands (other than ATDD, ATDT, and ATD) and never requires the 
RPCI-DI or PDIU-DI to send result codes to display on the PC display screen. Frequently, 
it is difficult to determine the full extent of these requirements; so Toshiba recommends 
turning LED 02 ON. See the PC/Data Interface User Guide for DIU AT commands and 
result codes.

DWD&DOO, and 0RGHP. Assign 6 buttons to data devices as required. Do not 
assign 
66 buttons to data devices; 66 buttons are used for voice calls only.
PDIU-DS to Printer Installation
Strata DK enables serial printers (laser, dot matrix, or other types) to be connected to stand-alone 
data interface units (PDIU-DSs). Digital telephones equipped with RPCI or PDIU-DIs can share 
access to these printers. Serial printers operate as DCE or DTE devices, depending on the vendor; 
the PDIU-DS can be connected to either type, since it can be configured as a DTE or DCE device. 
(The PDIU-DS comes from the factory configured as a DCE device.) 
ä
To connect the PDIU-DS to a serial printer
Notes
lOnly serial printers (not parallel) that conform to EIA RS-232 signaling requirements can be 
connected to PDIU-DSs.
lIn rare applications, it may be desired to connect printers to PDIU-DIs. See the printer’s 
installation instructions.
1.Consult the serial printer’s documentation and determine if the printer operates as a DCE or 
DTE device. Also, see Figures 10-32 and 10-34.
If the printer is a DCE device: Disassemble the PDIU-DS and configure it to operate like a 
DTE device by placing the jumper plugs (P1~P9) in the “B-C” (MODEM) position. 
Reassemble the PDIU-DS, and mark “B-C” on the bottom label for future reference. 
If the printer is a DTE device: You may not need to disassemble the PDIU-DS, since it comes 
factory-direct configured as a DCE device. However, if uncertain, disassemble the PDIU-DS 
and verify that jumper plugs (P1~P9) are in the “A-B” (DTE) position. Reassemble the PDIU-
DS and mark “A-B” on the bottom label for future reference. 
2. Connect the PDIU-DS to the appropriate digital telephone circuit per wiring diagrams in 
Chapter 8 – DK40i/DK424 Universal Slot PCB Wiring and Chapter 9 – Station Apparatus.
3. Connect the appropriate RS-232 cable between the printer and the PDIU-DS (see Figures 
10-27 and 10-30 for an example printer cable connection). 
4. If Steps 2 and 3 are done properly, the Power and Ready LEDs on the PDIU-DS light when the 
printer is turned on and ready.
5. Set the PDIU-DS DIP switch (SW1-1~4) for the application. See Figure 10-33 for DIP switch 
locations.
NoteIf using Toshiba computers and printers with X-ON/X-OFF flow control, set SW1-(4) 
“ON” on the DIU connected to the computer and DIU connected to the printer.

©LEDs 17~20: Data security groups can be used to enable or disable digital telephones 
equipped with PDIU-DIs access to PDIU-DS ports connected to a printer. DIU stations 
can only make data calls to DIUs in the same data security group.
©Program 22: Configures PDIU-DSs to hunt if more than one PDIU-DS connected to the same 
printer/server.
PDIU-DS to Modem Installation
Strata DK enables asynchronous-type (not synchronous) modems to be connected to PDIU-DSs. 
This enables RPCI-DI or PDIU-DI equipped digital telephones that are connected to personal 
computers, terminals, and other devices to share access to a modem or modem pool. 
Important!Modems must be “smart modems” that respond to AT commands and return result 
codes. Modems are customer-supplied.
A modem(s) can be accessed internally for outgoing data calls or externally for incoming data 
calls. Modems operate as DCE devices; so PDIU-DSs that are connected to them must be 
configured to operate like a DTE device. 
In the example shown in Figure 10-24 on Page 10-49, the line side of the two modems are 
connected to RDSU/RSTS, RSTU2, PSTU, or PESU ports to establish a modem pool; however, 
the line side of modems can be connected directly to a dedicated CO line.
If modems are connected directly to telephone network CO lines, automatic transfer of CO line 
voice calls to system modems (data call) do not function as described in the PC/Data Interface 
User Guide. 
For efficient operation and the best use of CO lines and modems, Toshiba recommends 
configuring modems to RSTU2, PSTU or RDSU/RSTS standard station ports in a modem pool. 
The RS-232 side of the modem connects to the PDIU-DS with standard RS-232 cables; the PDIU-
DS line side (RJ-11 connector) always connects to its own individual digital port.

ä
To configure the PDIU-DS as a DTE device
1.Disassemble the PDIU-DS and place jumper plugs P1~P9 in the “B-C” position (MODEM).
2. Reassemble the PDIU-DS and mark “B-C” on the bottom identification label for future 
reference. (See Figures 10-32 and 10-33.)
ä
 To install modems to PDIU-DSs
1. Connect the PDIU-DS to the appropriate digital port circuit per the wiring diagrams in Chapter 
8 – DK40i/DK424 Universal Slot PCB Wiring.
2. Connect the appropriate RS-232 cable between the modem and the PDIU-DS. Figure 10-29, 
“PDIU-DS to Hayes-Type Smart Modem, RS-232 Connector/Cable Connections” shows an 
example PDIU-DS to “smart modem” RS-232 connection. 
Important!All 10 PDIU-DS EIA leads (signals) should be connected to the modem. Consult the 
modem’s documentation for correct RS-232 pin requirements; the requirements may 
vary with each manufacturer.
3. Connect the line side of the modem to a RDSU/RSTS, RSTUS2, or PESU standard telephone 
circuit or a dedicated CO line (consult the modem’s documentation to install it to a CO line). 
Chapter 8 – DK40i/DK424 Universal Slot PCB Wiring provides station port wiring 
information.
4. Set the PDIU-DS DIP switch (SW1-1~4) for the desired application. (See Figures 10-32 and 
10-33.)
NoteIf the modem tracks carrier detect (DCD, AT&C1), SW1(4) should be ON, and SW1(2) 
should be OFF when PDIU-DS is connected to a modem.
5. Configure the PDIU-DS to connect to an asynchronous modem using Programs 20, 21, 22, 31 
and 33.

Modem Setup Recommendations
1. Always make sure the escape sequence of the telephone PDIU-DI is default (+++).
2. Send AT command ATS2=43 to PDIU-DI.
3. Use a modified modem cable for the connection (see Figures 10-29 and 10-38) or reset the 
PDIU-DS internal jumper plugs per the instructions in the DK Admin User Guide.
4. Send the following AT commands to the modem pool modem: ATS0=1, ATE0, ATQ0, 
AT&C1, and AT&D2.
PDIU-DS Disassembly and Assembly
