Figure 2 Interface Unit Used with Other Video Transmission Technologies

NOTE: The video signal and Bilinx control data require unobstructed two-way communication. Do not place active video devices in the coax line, because it will block the control data signals.

Passive devices, such as ground loop isolation transformers or other devices specifically designed to support Bilinx communication, can be placed in the coax line. In some configurations, it may be possible to connect an active device after the video passes through the head-end control unit. For sample applications, refer to the Typical Configuration Diagrams Section found later in this manual.

When an operating camera is connected to the Interface Unit, the video channel LED illuminates GREEN to indicate the presence of an acceptable video signal. As Bilinx control data is sent to or received from Bilinx-enabled cameras, the respective channel LED flashes accordingly.

4.4 Group ID Number

The rear panel of the Interface Unit contains a set of 3 rotary switches, as shown below. Use the straight slot side of the supplied offset screwdriver to set the switches to the necessary value.

EN 9

These switches are used to identify the group of cameras to be connected to the Interface Unit. Each group consists of 16 cameras in consecutive order, and the group must always end at an exact multiple of 16. For example, the lowest camera group range is from 1 to 16. The next group range is from

17 to 32, etc., up to the last group (camera range of 9985 to 9999). If multiple Interface Units are used in the same system, each Group ID number must be unique.

The following chart summarizes the supported switch settings:

Switch Setting	Use
001 to 625	Valid switch settings used for Allegiant and biphase
	controller interfaces
901 to 931	Settings used in Allegiant interface mode to
	terminate RS-485 data line
000	Reserved; setting is used during firmware upgrades
900	Reserved; setting is used by the factory

When the Interface Unit is connected to an Allegiant system using the Allegiant data interface protocol, the Group ID switches should always be set to correspond to the physical camera numbers used in the system. For control systems that use the biphase data interface, the switches should be set to correspond to the controller’s logical camera configuration.

After a change is made in a large Allegiant system with multiple Interface Units, 30 seconds may be required before the new settings take effect in all Interface Units.

Setting 900 is reserved for factory use. If the Interface Unit is inadvertently set to this value for more than 5 seconds before being set to its correct value, a power off/on may be required for the unit to return to its normal operating mode.
