4.6Allegiant Series Switcher Data Interface

4.6.1Allegiant 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.

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.

Allegiant		Supported Ports
Model	CONSOLE	PRINTER	ALARM1	COM1	COM2
LTC 8100	YES	NO	NO	NO	NO
LTC 8200	YES	NO	NO	NO	NO
LTC 8300	YES	YES	NO	NO	NO
LTC 8500	YES	YES	YES	NO	NO
LTC 8600	YES	YES	YES	YES	YES
LTC 8800	YES	YES	YES	YES	YES
LTC 8900	YES	YES	YES	YES	YES

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.

4.6.1.2Setting 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.

EN 14

IntuiKey Series Keyboard:

From the main Allegiant screen, navigate to the User Functions menu screen, then press [Enter User Command]. Key in 39, then press [Enter].

LTC 8555 or LTC 8550 Series Keyboard: Press [USER], key in 39, then press [Enter].

The monitor’s on-screen text will indicate the current configuration mode, such as NO DIU OPERATION (i.e., meaning No Data Interface Unit Operation) on a non-configured system. Use the keyboard joystick up/down to navigate through the available 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.

Figure 6 Allegiant On-screen Setup Procedure for Bilinx Operation

If the on-screen option reads No CTS Operation, the CPU firmware version is older than the revision needed for compatibility with Bilinx communication. On Allegiant systems sold after 1995, CPU upgrades can be done from an external PC using a software download approach. Older systems

(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.
