Pdiu-0S To Printer Installation - Toshiba Strata DK 280 Installation Manual

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-Dl'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
Subsection 6.9.2. Figures 6-26 and 6-3 1
provide diagrams for connecting RS-232
cables between PDIU-Dls and PCs/Toshiba
portables.
4. Set the RPCI-DI or PDIU-DI DIP switch (SWi-1 -
4) for the desired application. Figure 6-33 shows
the DIP switch locations and Subsection 6.9.3
describes switch functions.
5. Access Program 20 to configure the RPCI-DI or
PDIU-DI for DTE-type connection and Program 39
for data button assignments of the digital
telephone connected to the PDIU-DI.
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 use
RPCI or DIU AT commands (other than
ATDD, ATDT, and ATD) and never require 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 it is recommended to
turn LED 02 ON. See the Data Interface User
Guide for information regarding DIU AT
commands and result codes.
LEDs 03 and 04: Should be OFF for RPCI-DI
or PDIU-DI ports.
LED 05: Should be ON if the system
is
installed behind a PBX or Centrex that uses
access codes to make external-calls or to
insert a pause following RPCI DIU access of
an outside line.
LED 10: Enables Caller ID and ANI
information to be sent from RCPI-DI to the
connected PC.
LED 11: Enables DNIS information to be sent
from the RCPI-DI to the connected PC.
LEDs 17 - 20: Used to establish data security
groups. RPCI and PDIU stations are only
allowed to make calls to RPCI and PDlUs in
the same assigned data group.
Program 39-The following data call buttons can be
assigned digital telephones equipped with PDIU-Dls:
Data Call, and Modem. Assign SD buttons to data
devices as required. Do not assign DSS buttons to
data devices; DSS buttons are used for voice calls
only.
6.9.5 PDIU-DS to Printer Installation
Strata DK280 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-Dls 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.) Follow the
steps below to install the PDIU-DS to a serial printer.
Notes:
1. Only serial printers (not parallel) that
conform to EIA RS-232 signaling
requirements can be connected to PDIU-
DSs.
2. In rare applications, it may be desired to
connect printers to PDIU-Dls. Refer to the
printer's installation instructions.
1. Consult the serial printer's documentation and
determine if the printer operates as a DCE or DTE
device:
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 (Pl -
P9) in the "B-C" (MODEM) position.
Reassemble the PDIU-DS, and mark "B-C" on
the bottom identification label for future
reference. (Subsection 6.9.7 provides PDIU-
