Sdi Devices; Description; Installation; D9131A Parallel Printer Interface Module - Radionics D9000 Series Operation And Installation Manual

Description

The panel can support a number of accessory
devices off the SDI bus using terminals 29
through 32. Such devices include the D1255
Command Center (discussed in the previous
section), the D9131A Parallel Printer Interface,
and the D9210B Access Control Module.

Installation

Consult the Operation and Installation Manual of
the specific SDI device for complete installation
instructions. SDI devices connect to the panel in
parallel as shown in Table 7.

These devices may share power with the panel
or be powered by a stand-alone power source.
IMPORTANT! A stand-alone power supply
powering any SDI device must also be connected
to a common terminal on the panel. Do not
connect the stand-alone power supply to earth
ground other than terminal 10 on the panel.

D9131A Parallel Printer Interface Module

The Radionics D9131A Parallel Printer Interface
is a 4-wire powered device used to connect a
standard parallel printer to panel. The D9412/
D9112 can supervise three printers, and the
D7412/D7212 can supervise one printer. Each
printer requires a separate D9131A Printer
Interface Module. The D9131A connects to the
printer using a standard parallel printer cable.

Switch Settings

Switches on the D9131A assign a unique
address (17 to 19) to each printer. The address
determines if the printer is supervised, the
printer's scope, and what area the printer is
assigned to. See Printer Parameters in the
D9000/D7000 Series Program Entry Guide (74-
07695-000) for a complete description of
addresses.
Table 8 shows the correct switch setting for each
address.

Supervision

Supervision includes proper operation of the SDI
bus, proper connection of the printer cable
between the printer and the D9131A, printer
paper supply, printer selected (on-line), and
printer power.
The panel sends an SDI failure report to the
receiver if it fails to communicate with the printer
interface, and SERVC PRINTER displays at the
Command Center. The report to the receiver
includes the address of the troubled D9131A so
you know which printer needs service.
NOTE: If you are upgrading a D9112B1 system
that currently uses a D9131 Printer Interface
module, you may order a D9131A Printer
Interface Update Kit to update the D9131 to a
D9131A.
