11.0 SDI Devices
11.1 Description
D9412G/D7412G 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 (discussed in the previous section),
D9131A Parallel Printer Interface Module, D9210B
Wiegand Control Interface Module, D9133 Serial
Interface Module, and D9133TTL-E Network Interface
Module.
11.2 Installation
Consult the specific SDI device Operation and
Installation Guide for complete installation instructions.
SDI devices connect to the panel in parallel as shown in
Table 19.
These devices can share power with the panel or be
powered by a stand-alone power source.
A stand-alone power supply powering the
SDI device must also be connected to a
common terminal on the panel. Do not
connect the stand-alone power supply’s earth
ground to Terminal 10 on the panel.
11.3 D9131A Parallel Printer Interface
Module
The Bosch Security Systems D9131A Parallel Printer
Interface Module is a 4-wire powered device used to
connect a standard parallel printer to a panel. D9412G
can supervise three printers and D7412G can supervise
one printer. Each printer requires a separate D9131A
Parallel Printer Interface Module. The D9131A connects
to the printer using a standard parallel printer cable.
11.3.1 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 the area to which
the printer is assigned. See Printer Parameters in the
D9412G/D7412G Program Entry Guide for a complete
description of addresses.
Table 20 shows the correct switch setting for each
address.

11.3.2 Supervision
Supervision includes the 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 to indicate which printer needs service.
If an SDI device is supervised and SDI A becomes
disconnected, the device can continue to operate
normally, depending upon environmental conditions.
11.4 D9210B Wiegand Control Interface
Module
The Bosch Security Systems D9210B Wiegand
Control
Interface Module is a 4-wire powered device providing
connections for an access door point and door strike.
The D9412G can supervise eight Wiegand
Control
Modules, the D7412G can supervise two. Each D9210B
supports one door to control access. Programming
allows each access door to be configured independently.
Using Wiegand
style cards or tokens, the D9210B can
allow access for up to 996 cards/tokens on the D9412G,
396 on the D7412G. User access authority can be
configured to restrict access to certain doors or to
certain periods of time. The reading of access cards, in
addition to granting access, can control whether the
system will disarm. Used with the D9412G, the D9210B
recognizes 249 master users by user name, passcode, and
access authority. The D9210B recognizes 99 master users
when used with the D7412G. Each master user supports
three sub-users with unique cards/tokens having the
same access level as the master user.
11.4.1 Switch Settings
Switches on the D9210B assign a unique address (1 to 8)
to each module. Table 21 shows the correct switch setting
for each D9210B address.
