12.0 SDI Devices

12.1 Description

The D7212GV3 Control Panel can support a number

of accessory devices from the SDI Bus using

Terminals 29 through 32. Some devices include the

D1255RB and D1255 Keypads (refer to Section 11.0

Arming Devices on page 44), D9131A Parallel Printer

Interface Module, ITS-DX4020-G GPRS/GSM

Communicator, and DX4020 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 19).

These devices can share power with the control 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 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, Inc. D9131A Parallel

Printer Interface Module is a four-wire powered device

used to connect a standard parallel printer to a control

panel. The D7212GV3 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 D7212GV3 Program Entry

Guide (P/N: F01U170808) for a complete description

of addresses.

Table 20 shows the correct switch setting for Address

17.

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 88 and 92

SDI Address 88 and 92 are available with the

D7212GV3 Control Panel and are used for several

different applications. Only one device can be

assigned to SDI Address 88 at a time. Likewise, only

one device can be assigned to SDI Address 92 at a

time.

12.4.1 Network Interface Modules

The Bosch Security Systems, Inc. DX4020 Network

Interface Module is a four-wire powered SDI device

that provides connection for two-way communication

over Ethernet networks to the D7212GV3.

For programming information on enhanced

communications, refer to the D7212GV3 Program

Entry Guide (P/N: F01U170808).

The DX4020 can be installed up to 305 m (1000 ft)

from the control panel using 0.8 mm (22 AWG) wire.

The ITS-DX4020-G GPRS/GSM IP Communicator

enables two-way IP or dialed communication over a

commercial GPRS/GSM network. Typical applications

are event reporting to a central monitoring station and

remote access to Bosch intrusion control panels.
