12.0 SDI Devices
12.1 Description
D9412GV2 or D7412GV2 Control Panels 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 53), 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 22).
These devices can share power with the control panel
or be powered by a stand-alone power source.

29 COMMON Black 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.
12.3 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.
D9412GV2 can supervise three printers and
D7412GV2 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 D9412GV2/D7412GV2 Program
Entry Guide (P/N: F01U003636) for a complete
description of addresses.
Table 23 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 D9210B Wiegand Control Interface
Module
The Bosch Security Systems D9210B Wiegand Control
Interface Module is a four-wire powered device
providing connections for an access door point and
door strike. The D9412GV2 can supervise eight
Wiegand Control Modules, the D7412GV2 can
supervise two. Each D9210B supports one door to
control access. Programming allows each access door
to be configured independently.
