semble 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
identification label for future reference.
(Paragraph 12.70 provides PDIU-DS dis-
assembly/assembly instructions, and
Figure 8-35 provides jumper plug
information.)
NOTE:
Do not cut the PERCEPTION strap when
installing a PDIU-DS in a STRATA DK system.
•
If the printer is a DTE device: It may not
be necessary to disassemble the PDIU-
DS, since it comes direct from the factory
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 identification label for future ref-
erence. (Paragraph 12.70 provides PDIU-
DS disassembly/assembly instructions,
and Figure 8-35 provides jumper plug
information.)
2) Connect the PDIU-DS to the appropriate PDKU
circuit per wiring diagrams in Section 400-
096-209.
3) Connect the appropriate RS-232 cable be-
tween the printer and the PDIU-DS. (See
Figure 8-31 for an example printer cable
connection.)
4) If Steps 2 and 3 are done properly, the Power
and Ready LEDs on the PDIU-DS should light
when the printer is turned on and ready.
5) Set the PDIU-DS DIP switch (SW1-1 ~ 4) for
the desired application. Figure 8-36 shows the
DIP switch locations and Paragraph 12.30
describes switch functions.
IMPORTANT NOTE!
Check the printer’s serial documentation
for correct RS-232 pin requirements. The
requirements vary with each manufacturer.
6) Use Program 20 to configure the PDIU-DS to
connect to a serial printer. (See Programming
Section 400-096-302 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.
•
LED 06: Normally OFF for PDIU-DS ports
connected to printers.
•
LEDs 17 ~ 20: Data security groups can
be used to allow or deny digital telephones
equipped with PDIU-DIs access to PDIU-
DS ports connected to a printer. PDIU-DI
stations can only make data calls to DIUs
in the same data security group.
7) Program 22 should be used to configure
PDIU-DSs to hunt if more than one PDIU-DS
is connected to the same printer/server.
12.60 PDIU-DS To Modem Installation
12.61 Asynchronous-type (not synchronous) mo-
dems can be connected to PDIU-DSs. This allows
PDIU-DI-equipped digital telephones that are con-
nected to personal computers, terminals, and other
devices to share access to a modem or modem
pool.
IMPORTANT NOTE!
Modems must be “smart modems” that
respond to AT commands and return re-
sult codes. Modems are customer-sup-
plied.
12.62 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
