12.50 PDIU-DS To Printer Installation
12.51 The STRATA DK
(Release
3) enables serial
printers (laser, dot matrix, or other types) to be
connectedtostand-alonedatainterfaceunits(PDIU-
DSs). Digital telephones equipped with 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 con-
form to EIA RS-232signaling requirements
can be connected to PDIU-DSs.
2. In rare applications, it may be desired to
connectprinters to PDIU-Dls. Refer to the
printer’s ins talla tion instructions.
1) Consult theserial printer’s documentation and
determine if the printer operates as a DCE or
DTE device:
l
If the printer is a DCE device: Disas-
semble the PDIU-DS and configure it to
operate like a DTE device by placing the
jumper plugs
(PI - P9)
in the “B-C” (MO-
DEM) position. Reassemble the PDIU-
DS, and mark “B-C” on the bottom iden-
tification label for future reference. (Para-
graph 12.70 provides PDIU-DS disas-
sembly/assembly instructions, and Figure
8-28 provides jumper plug information.)
l
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
(Pl - 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 8-28 provides jumper plug
information.)
2) Connect the PDIU-DS to the appropriate PDKU
circuit perwiring diagrams in Section 200-096-
209 and information provided in Section 200-
096-207.
3) Connect the appropriate RS-232 cable be-
tween the printer and the PDIU-DS (see Fig-
ure 8-31 for an example printer cable connec-
tion).
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
(SWI-1 - 4)
for
the desired application. Figure 8-26 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.

Use
Program
20 to configure the PDIU-DS to
connect to a serial printer (see Pogramming
Section 200-096-302 for instructions and
record sheets).
