Important!
Check the printer’s serial documentation for correct RS-232 pin requirements. The
requirements vary with each manufacturer.
PDIU-DS Programming
♦
Program 20: Configures the PDIU-DS to connect to a serial printer (see
Strata DK
Programming Manual
for instructions and record sheets).
♦
LED 01: Should always be On for PDIU-DS ports.
♦
LED 02: Should be Off for PDIU-DS ports connected to printers.
♦
LED 03: Should be Off for PDIU-DS ports that connect to DTE- or DCE-type printers.
♦
LED 04: Should always be On for PDIU-DS ports.
♦
LED 05: Should be Off for PDIU-DS ports connected to printers.
♦
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
, 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 (RJ11 connector) always connects to its own individual digital port.
➤
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
➤
To install modems to PDIU-DSs
1. Connect the PDIU-DS to the appropriate digital port circuit per the wiring diagrams in
