RPCI-DI Buttons and LEDs
In system programming, the data telephone can be assigned data feature buttons 
shown below.
Table 1 Data Feature Buttons 
ButtonDescription
DWD&DOO
Enables a connection between the digital telephone’s RPCI-DI to another DIU in 
the system when manually dialing from the telephone. When 
DWD&DOOis pressed 
on an idle data telephone, the system sends intercom dial tone to the telephone to 
prompt dialing. 
DWD&DOOalso can be used to switch data telephones and CO lines 
from voice to data on external calls.
The Data Call LED lights when you receive a data call from another data telephone 
or when you make a call from your data telephone, PC, or ASCII terminal. The Data 
Call LED is always red when ON.
DWD5HOHDVHTerminates data calls. The Data Release LED never illuminates.
0RGHP
Reserves a system modem for 60 seconds. If a modem is not accessed within this 
time limit, press this button again to reserve for another 60 seconds.
A flashing Modem LED indicates that a modem is currently reserved for your 
telephone; a continuously lit LED indicates that you have accessed a modem or 
that all modems are busy. The Modem LED is always red when ON or flashing.

RPCI-DI Data Connections
See the Strata DK I&M Manual
 for detailed installation instructions.
If a data terminal is connected to a data telephone, the terminal must be an ASCII type 
with a standard keyboard and a display screen or printer display. 
If a PC is connected to a data telephone, the PC must be running at least one of the 
following types of programs: word processor, desk organizer dialer, or 
communications software. Also, the PC must be active (on-line) on its COM port 
connected to the data telephone’s RPCI-DI.
NoteIt is not possible to establish data call connections from your PC DOS prompt.
The data telephone is connected to the PC serial communications port (COMX, where 
X = 1, 2, 3, or 4) or terminal with an RS-232 cable and connector. It is connected to 
the Strata DK system like any other digital telephone with a modular cord.

Stand-alone Data Interface Unit (PDIU-DS) 
Connections
Data devices, such as printers, modems, mainframe computers, etc., must be 
connected to a PDIU-DS with an RS-232 cable and connector. An RS-232 connector 
is below (see Figure 2).
Figure 2 Stand-alone DIU Connector
See the Strata DK I&M Manual
 for detailed installation instructions.
Note
lThe PDIU-DS must be connected to the Strata DK system with a modular cord. 
Similar to a regular station, the PDIU-DS is assigned a station number.
lToshiba recommends connecting the line sides of the modems to standard 
telephone ports to ensure access to the complete set of modem pooling features. 
Connecting the modems to a dedicated CO line may not allow access to the whole 
set.

Communication Parameters
Strata DK PC/Data Interface 5/997
Communication Parameters
Before a data connection is established, the communication parameters—data speed 
(baud rate or bps), parity, data bits, stop bits—of the terminal or PC must be the same 
as the data device that is calling or being called. The PC communication parameters 
are set with MS-DOS MODE commands.
äTo set the PC Communication parameters
Communication parameter options are shown in Ta b l e  3. äEnter MODE 
LPTx:=COMx
(x = 1, 2, 3, or 4)Use this parameter, if you connect to your printer via 
an RPCI to DIU-DS data call connection.
...or MODE COMx: 
baud rate, parity, data 
bits, stop bits
Notes
lToshiba recommends entering these MODE 
command lines into the DOS AUTOEXEC.BAT 
file, in most cases. 
lThe COM port number and communication 
parameters must be set to allow proper operation 
of data calls in most communications, desktop, and 
word processor software.

Features2
This chapter explains how to use your data telephone to connect to other data devices, 
such as an internal printer, modem pool, or mainframe computer. It also explains how 
to originate and answer simultaneous voice and data transmissions from your 
telephone or another telephone.
Data Call to Internal Printer or Other Data Device
If using a PC, data calls to printers can be connected anytime while running a word 
processor, spread sheet, or database program. This procedure can also be used to make 
data calls to other internal data devices, such as modems or mainframe computers, that 
are connected to stand-alone DIUs. A communications software program is generally 
required for these types of internal data calls.
Before making your call, verify that the communication parameters of your PC or 
terminal match those of the printer or data device you are calling.

Data Call to Another Internal Data Telephone’s 
PC or Terminal
PCs involved in this call must be running a communications software program.
Before making this call, verify that the communication parameters of your PC or 
terminal match those of the PC or terminal that you are calling.
The following instructions work with typical communications software programs. 
Higher-level software may integrate these low-level communications dialing 
commands to provide more automated operation.1. Press 
DWD&DOOon 
your data telephone.The Data Call, Spkr, and Mic (see note) LEDs turn ON 
(red); and the [DN] LED turns ON (green). The data 
telephone receives internal dial tone.
NoteDepending on system programming, the Mic 
LED may or may not turn ON.
2. Enter the station 
number of the DIU 
connected to the 
printer.The Spkr, Mic, and [DN] LEDs turn OFF; the Data 
Call LED remains ON (red).
If busy, press 
DWD5HOHDVHand try again; if busy 
tone is not received, the call is connected.
3. Print the data. The data can be printed using your terminal or PC 
software program.
äPress 
DWD5HOHDVH 
on your data 
telephone.The Data Call LED turns OFF and the call is 
terminated.

The [DN] of a data telephone’s RPCI-DI is the same as 
its voice [PDN].
Example: If the other data telephone’s [PDN] is 209, 
type ATDD209 and press Enter. (ATDD is the DIU 
command for data call dialing, and 209 represents the 
[PDN] of the other data telephone).
2. Exchange data. The data can be exchanged using your terminal or PC 
software program as required.
