MCN System Manual CTI Products, Inc. System Operation For Comparator I/O Modules, such as the AIB module, that support more than 8 receivers, the receivers are grouped into banks of 8 receivers. Some User Interface Modules, such as HIBs operating with the MCN Remote Comparator Display software support only bank 0. Other User Interface Modules, such as the IIB, can be configured to control any one of the 8 banks. Below is a list of the MCN banks and the receivers contained in those banks.
MCN System Manual CTI Products, Inc. 7. Hardware Installation Hardware Installation This section describes how MCN modules are installed into a system. All MCN modules follow the same basic installation procedure. Some modules may have additional installation requirements. Refer to the module’s hardware reference manual for any additional installation information. Below is a list of steps required for installing an MCN system. Step Operation 1 Determine the addresses of all MCN modules.
MCN System Manual CTI Products, Inc. Setting the Unit Address Each MCN module is identified by a unique address that must be set at installation time. This address is specified by the combination of a Group number and a Module number. On all modules (except the HIB) the Group and Module numbers are assigned with the rotary switches on either the front or back of the module. Whenever the Group or Module number is changed, the module must be reset or power cycled for the change to occur.
MCN System Manual CTI Products, Inc. 7.1.1 Hardware Installation Address Planning To help organize the MCN system, we have provided the following guidelines for assigning unit addresses: • Assign all Comparator I/O Modules to the same Group or set of Groups (if you have more than 16 modules), typically beginning with Group 00, Module 0 and progressing sequentially.
MCN System Manual CTI Products, Inc. Hardware Installation Figure 7 shows a system that has three Comparator I/O Modules located in comparator room A, two Comparator I/O Modules located in comparator room B, two User Interface Modules located at a maintenance site and two User Interface Modules located in a dispatch room. For this system, all of the modules in a single room are set to the same Group number. All modules in comparator room A are assigned to Group 01.

This LED will blink if the input voltage falls below the minimum specified input voltage level.
MCN System Manual CTI Products, Inc. 9. System Examples System Examples The following examples show how MCN modules are combined to form various systems, as well as the capabilities of those systems. 9.1 Example 1 - 8 Receivers with a Console Display Figure 15 shows an MCN system that provides monitoring and control of up to 8 receivers connected to a Motorola ASTRO-TAC™ Comparator. Only 8 receivers are supported because only one IIB module is in the system.
MCN System Manual CTI Products, Inc. 9.2 System Examples Example 2 - PC Based Monitoring and Control Figure 16 shows a system that provides local monitoring and control of up to 8 receivers utilizing a PC as the operator interface. CTI Product’s Remote Comparator Display software running on the PC allows each receiver of the comparator to be individually controlled.
MCN System Manual CTI Products, Inc. 9.3 System Examples Example 3 - 16 Receivers with a Console Display A multiple comparator system is shown in Figure 17. This system implements monitoring and control of 3 different comparators from one console. Notice that in this system, one CIB module is being used to control receivers from two comparators (comparators 1 and 2). The only requirement for this setup is that both comparators 1 and 2 are the same type (i.e.
MCN System Manual CTI Products, Inc. 9.4 System Examples Example 4 - 24 Receivers with Multiple Operator Stations The example in Figure 18 shows a much larger system than the previous examples. Three CIB modules are used to control a total of 24 receivers. The three IIB modules can be used to provide control of all receivers from the main console. Each PC in the system can control all receivers as well. The HIB modules provide both local and remote control of all receivers.
MCN System Manual CTI Products, Inc. System Examples There is one limitation of a system which uses both HIBs and IIBs together to control the same comparator. If a receiver is disabled from the console (this is a latched disable), the two PC displays will report the receiver as disabled when the comparator disables that receiver.
MCN System Manual CTI Products, Inc. 9.5 System Examples Example 5 - Steered Transmitter System Figure 19 shows an example system using the TIB module with a TSAM to provide transmitter steering as well as comparator monitoring and control.
MCN System Manual CTI Products, Inc. System Examples operator’s PC. To force the TSAM to steer to transmitter 1, the operator will generate a FORCE VOTE for receiver 1. The TIB will receive this FORCE VOTE for receiver 1 and setup the Tx Select lines for transmitter 1 and the Force Select line. When the TIB activates the Force Select line to the TSAM, the TSAM will immediately steer to transmitter 1. The FORCE VOTE for receiver 1 will also cause the CIB to generate a FORCE VOTE command to the comparator.
