Interface
4.6.1 Allegiant Interface Configurations
When using the Allegiant data interface protocol, up
to 31 Interface Units can be connected to a single
large Allegiant system. In this configuration, bi-
directional Bilinx communication to physical cameras
ranging from 1 to 496 is supported. In very large
systems, additional units can be interfaced to the
Allegiant via biphase data connection.
When connecting to an Allegiant system, select a data
port on the main Allegiant CPU that will be used to
communicate with the Interface Unit. The Interface
Unit provides separate interface connectors so it is
able to support both RS-232 and RS-485 Allegiant
interfaces.
IMPORTANT: Only one port on the Interface Unit
can be used at a time. Connecting data cables to more
than one port on the Interface Unit simultaneously
could result in non-operation.
4.6.1.1 Allegiant Interface Port Selection
Based on the Allegiant model being used, select an
available CPU port from the table below. Note that it
is not possible to connect the Interface Unit cable to a
Console port provided by an Allegiant LTC 8712
Series Port Expander accessory unit.

IMPORTANT: The ALARM port requires a special
cable pinout. DO NOT USE the supplied cable for
this port connection. A cable must be constructed
by the installer, per the pinouts shown in the
CONNECTOR & CABLE PINOUTS section.
4.6.1.2 Setting the Allegiant System to Use Bilinx
Communication Mode
Using Allegiant Keyboard User Function 39, a system
keyboard operator with Level 1 Priority must configure
the Allegiant to enable the communication interface on
the selected port.

options. Enter the operator password when prompted,
and press [ENTER] to select the port currently shown.
The port is now configured with the proper baud rate
and handshake settings to communicate with the
Interface Unit.

YES
CPU upgrades can be done from an external PC
using a software download approach. Older systems
YES
(i.e., having CPU modules with a single 8-position dip
switch) can be upgraded by replacing the CPU
module. Contact the nearest Bosch Security Systems
Sales Representative or Tech Support specialist for
additional details on Allegiant CPU upgrades.
A system reset is required to complete the process.
Either use Keyboard User Function 15, or power
off/on the main Allegiant CPU bay. The Allegiant is
then ready to communicate with the Interface Unit.
