12.0 SDI Devices
12.1
Description
The D7212GV2 Control Panel can support a number
of accessory devices from the SDI Bus using Terminals
29 through 32. Some devices include the D1255
Command Center (keypad) (refer to Section 11.0 Arming
Devices on page 44), D9131A Parallel Printer Interface
Module, D9210B Wiegand Control Interface Module,
DX4010i RS-232 Serial Interface Module, D9133 Serial
Interface Module, DX4020 Network Interface Module,
and D9133TTL-E Network Interface Module.
12.2
Installation
For complete installation instructions, consult the
operation and installation guide for the specific SDI
device. SDI devices connect to the control panel in
parallel (Table 20).
These devices can share power with the control panel
or be powered by a stand-alone power source.

COMMON
A stand-alone power supply powering the
SDI device must also be connected to a
common terminal on the control panel.
Do not connect the earth ground for the
stand-alone power supply to Terminal 10
on the control panel.

D9131A Parallel Printer Interface
Module
The Bosch Security Systems D9131A Parallel Printer
Interface Module is a four-wire powered device used to
connect a standard parallel printer to a control panel.
The D7212GV2 can supervise one printer. A separate
D9131A Parallel Printer Interface Module is necessary
for each printer. The D9131A connects to the printer
using a standard parallel printer cable.

12.3.1 Switch Settings
Switches on the D9131A assign a unique address (17 to
19) for each printer. The address determines if the
printer is supervised, the area scope of the printers, and
the area to which the printer is assigned. Refer to
Printer Parameters in the D7212GV2 Program Entry Guide
(P/N: F01U003804) for a complete description of
addresses.
Table 21 shows the correct switch setting for each
address.

12.3.2 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)
•
Printer power.
The control panel sends an SDI Failure Report to the
receiver if communication with the printer interface
fails. If an SDI failure occurs, SERVC PRINTER
appears at the keypad. The report to the receiver
includes the address of the troubled D9131A to
indicate which printer needs service.
If an SDI device is supervised and Terminal SDI A
becomes disconnected, the device can continue to
operate normally, depending upon environmental
conditions.
12.4
SDI Address 80
SDI Address 80, available on the D7212GV2 Control
Panel, allows for two-way SDI to RS-232 information.
This address is used with home or building automation
software. A D9133 Serial Interface Module is required
for this application.
12.4.1 Serial Interface Modules (SIMs)
The DX4010i RS-232 Serial Interface Module and the
D9133 Serial Interface Module are four-wire powered
SDI devices that connect RS-232 devices to the
D7212GV2 Control Panel. They use a specific
communication protocol that is provided upon request.
