AIB Hardware Reference CTI Products, Inc. 1. Introduction Introduction The ASTRO-TAC™ Comparator Interface Module (AIB) is a member of the Monitoring and Control Network (MCN™) family of Comparator I/O Modules. Hardware specifications, special installation, and configuration information are described in this manual. The AIB module connects a Motorola ASTRO-TAC™ (VSELP signaling) or ASTRO-TAC™ 3000 (APCO Project 25 IMBE signaling) Comparator to the MCN network.
AIB Hardware Reference CTI Products, Inc. 2. Theory of Operation Theory of Operation This section describes the operation of the AIB module in an MCN comparator display system. The AIB module must be configured for the comparator it is operating with, either an ASTRO-TAC™ or an ASTRO-TAC™ 3000 Comparator. Section 4 describes the ASTRO-TAC™ select option switch used for this configuration When used with an ASTRO-TAC™ 3000 Comparator, the AIB provides monitoring and control for up to 64 receivers.
AIB Hardware Reference CTI Products, Inc. Theory of Operation The AIB updates the ASTRO-TAC™ Comparator with the latest control information every second and whenever a FORCE VOTE or DISABLE command is received from a User Interface Module. 2.

AIB Hardware Reference CTI Products, Inc. 4. Option Switches Option Switches Five sets of option switches are provided for module configuration. The module must be power cycled or reset after these switches are set so that the options will take effect. Table 2 describes the option switches and shows the factory defaults.
AIB Hardware Reference CTI Products, Inc. Option Switches Clock and RX Clock) are used for direct connection between the AIB and ASTRO-TAC™ Comparator.
AIB Hardware Reference CTI Products, Inc. 5. Connectors Connectors The NETWORK IN/OUT ports on the front of the AIB are used to connect the AIB with other MCN modules. These ports carry both the network data signals and the DC power for power distribution with other modules. Table 6 gives the pinout for these connectors. Figure 3 shows the location of pin 1 for each port. PRODUCTS, INC.

CAUTION Make sure that any mounting screws used to secure unit to a bracket do not protrude into the unit’s enclosure more than 1/8 inches from the bottom surface of the unit. Using a larger screw that touches the pc board inside the unit may damage the unit when it is powered. Doing so will void the unit’s warranty. 7.

For additional troubleshooting tips, refer to the troubleshooting section found in the Monitoring and Control Network System Manual, reference 1. Due to the high percentage of surface-mount components the AIB is treated as a field replaceable unit.
AIB Hardware Reference CTI Products, Inc. PROBLEM User interface is not showing correct status OR Operator cannot FORCE VOTE or DISABLE the receivers Troubleshooting CAUSE Verify that the AIB’s OPTION A, switch 8 is set for the proper comparator type. If not, change the switch and reset the AIB. Connect the cable between the AIB and the ASTRO-TAC™ Comparator.
