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.
Note
The 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.
➤
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 11 – 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 11
– Station Apparatus.
Note
The 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 12-49 . Figures 12-32 and
12-30 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
12-32, “RPCI-DI, PDIU-DI, PDIU-DS SW1 DIP Switch Information” .
RPCI-DI and PDIU-DI Programming
Configure the RPCI-DI or PDIU-DI for DTE-type connection in Program 20 and the data button
assignments of the digital telephone connected to the PDIU-DI in Program 39.
♦
Program 20
♦ The port number entered for the RPCI-DI or PDIU-DI in Program 20 is the port number of
the digital telephone to which the RPCI-DI or PDIU-DI is connected.
♦ 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.
♦ LEDs 03 and 04: Should be Off for RPCI-DI or PDIU-DI ports.
