FEBRUARY1992
NOTES:
1. Only serial printers that conform to EIA
M-232 signaling requirements can be
connected to PDIU-DS units.
2. In rare applications, printers can be con-
nected 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:
l
As a DCE device:
a) Disassemble the PDIU-DS, and con-
figure it to operate like a DTE device
by placing the jumper plugs PI - P9
in the "B-C" (MODEM) position.
b) Reassemble the PDIU-DS, and mark
"B-C" on the bottom identification la-
bel for future reference. (Paragraph
6.170 provides PDIU-DS disassem-
bly/assembly instructions, and Fig-
ure 4-54 provides jumper plug infor-
mation).
l
As 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,
a) Disassemble the PDIU-DS, and verify
that jumper plugs PI - P9 are in the
"A-B" (DTE) position for DTE opera-
tion.
b) Reassemble the PDIU-DS and mark
"A-B" on the bottom identification la-
bel for future reference. (Paragraph
6.170 provides PDIU-DS disassem-
bly/assembly instructions, and Fig-
ure 4-54 provides jumper plug infor-
mation).
2) Connect the PDIU-DS to the appropriate NDKU
circuit in accordance with the wiring diagrams
in Section 200-255-205.
3) Connect the appropriate RS-232 cable be-
tween the printer and the PDIU-DS.
4) If steps 2 and 3 are properly done, the POWER
and READY LEDs on the PDIU-DS should
light when the printer is turned on.
IMPORTANT NOTE!
Check the printer' s serial documentation
for correct RS-232 pin requirements. The
requirements vary with each manufacturer.
5) Refer to the DDIU Program for PDIU-DS data
assignments.
IMPORTANT NOTE!
The eighth port (circuit) of the NDKU can-
not be used for data switching connection
(PDIU-DI or PDIU-DS).
6.160 PDIU-DS To Modem Installation
6.161 With D.04 software, PERCEPTIONeLe,
enables asynchronous-type (not synchronous)
modems to be connected to PDIU-DS' s. This al-
lows PDIU-Dl-equipped digital telephones that are
connected to PCs, terminals, and other devices to
share access to a modem.
6.162 Modems can be accessed internally for out-
going data calls or externally for incoming data
calls. Modems operate as DCE devices, so the
PDIU-DS must be configured to operate like DTE
devices. The installation example in Figure 4-51
shows that two modems are connected to NSTU
ports; however, the line side of modems can be
directly connected to a dedicated CO line. The
modem connects to the PDIU-DS with a standard
RS-232 connector; the PDIU-DS line side (RJ-I 1
connector) always connects to its own individual
NDKU port. Use the following instructions to con-
nect modems to PDIU-DS' s.
1) Configure the PDIU-DS as a DTE device:
a) Disassemble the PDIU-DS, and place
jumper plugs PI - P9 in the "B-C" position
(MODEM).
b) Reassemble the PDIU-DS, and mark "B-C"
on the bottom identification label for future
reference (Paragraph 6.170 provides
