IIB Hardware Reference CTI Products, Inc. 1. Introduction Introduction The Input/Output Interface Module (IIB) is a member of the Monitoring and Control Network (MCN™ ) family of User Interface Modules. Hardware specifications, special installation, and configuration information are described in this manual. The IIB module connects a parallel operator display device (such as a console) to the MCN network.

IIB Hardware Reference CTI Products, Inc. 3. Theory of Operation Theory of Operation This section describes the operation of the IIB module in an MCN comparator display system. 3.1 Comparator Status The Comparator I/O Module (such as an AIB or CIB) accepts the VOTE, RECEIVE, DISABLE, and FAIL receiver status indicators from the comparator. It sends status messages to the IIB module.
IIB Hardware Reference CTI Products, Inc. Theory of Operation If the comparator detects that a receiver has failed, it sends a FAIL command to the Comparator I/O Module. Again, the Comparator I/O Module sends this FAIL command to the IIB so that the user can see that the receiver has failed. From the console, the user can generate FORCE VOTE or DISABLE commands for each receiver in the system.
IIB Hardware Reference CTI Products, Inc. 3.6 Theory of Operation Parallel I/O Signals The IIB provides two input/output lines per receiver (VOTE and DISABLE) that allow both monitoring and control of the signal. Two output only lines per receiver (FAIL and RECEIVE) are also provided. None of these I/O lines are latched in the IIB. In the console, the VOTE switch or button should be momentary, and the DISABLE switch or button should be latched.
IIB Hardware Reference CTI Products, Inc. 3.8 Theory of Operation Example Connections to a Console Figure 5 shows how an IIB may be connected to a console. Notice that the VOTE and DISABLE lines between the IIB and the console are bi-directional.
IIB Hardware Reference CTI Products, Inc. 4. Option Switches Option Switches Three 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.
IIB Hardware Reference CTI Products, Inc. Option Switches When the IIB is used with a Comparator I/O Module that supports only 8 receivers, such as a CIB, bank 0 will always be used. Figure 6 shows the configuration of the two jumper options available on the rear of the IIB. These jumpers should be installed at system installation time with power removed from the IIB. E1 A E1 B CA-80024-100 Figure 6 - Jumper Options Jumper E1A is located across the top 2 terminals of the 6 pin terminal block.
IIB Hardware Reference CTI Products, Inc. 5. Connectors Connectors The NETWORK IN/OUT ports on the front of the IIB are used to connect the IIB with other MCN modules. These ports carry both the network data signals as well as DC power for power distribution with other modules. . Table 4 gives the pinout for these connectors. Figure 8 shows the location of pin 1 for each port. PRODUCTS, INC.
IIB Hardware Reference CTI Products, Inc. Signal VOTE RX DIS FAIL Connectors Direction Description Input/Output Output activated when comparator votes that receiver. Ground input to force vote a receiver. Output Activated when comparator detects a valid signal on the receiver. Input/Output Output activated when receiver is disabled by comparator. Ground input to disable the receiver. Output Activated when receiver failure is detected by the comparator.

IIB Hardware Reference CTI Products, Inc. Special Installation Instructions 6. Special Installation Instructions 6.1 Unit Address Setting An IIB must be programmed with two unit addresses: 1. the address of the Comparator I/O Module it will operate with 2. the IIB’s own address You only need to perform this programming once, at installation time.
IIB Hardware Reference CTI Products, Inc. Special Installation Instructions the unit address programming steps.
IIB Hardware Reference CTI Products, Inc. Special Installation Instructions For example, Figure 10 shows a system with a single IIB and Comparator I/O Module. The following steps show how the system might be setup, using the following address assignments: • IIB address is Group 80, Module 0 • Comparator I/O Module is Group 00, Module 0 Step 1 2 3 4 5 6 7 7 8 9 10 11 12 13 Action Connect the network cable between the IIB NETWORK OUT port and the Comparator I/O Module’s NETWORK IN port.
IIB Hardware Reference CTI Products, Inc. 7. Special Features 7.1 Link Failure Reporting Special Features The IIB has a selectable option to show communication link failures between the IIB and its Comparator I/O Module (network link failures) or between the Comparator I/O Module and the comparator (comparator link failures). With this option enabled, the IIB will always report network link failures.
IIB Hardware Reference CTI Products, Inc. 8. Mounting Mounting Refer the reference 1, section Mounting Options, for details about mounting the IIB module. 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.

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 IIB is treated as a field replaceable unit.
