THEORY OF OPERATION ..................................................
CHIB Hardware Reference CTI Products, Inc. 1. Introduction Introduction The CommandSTAR Lite Host Interface Module (CHIB) is a member of the Monitoring and Control Network (MCN™) family of User Interface Modules. Hardware specifications and configuration information are described in this manual. The CHIB module connects to a CommandSTAR Lite Console.
CHIB Hardware Reference CTI Products, Inc. 2. Theory of Operation Theory of Operation The CHIB module does not provide any direct monitoring or control functions. Its purpose is to bridge the MCN network to the CommandSTAR Lite console. The CHIB module emulates a series of I/O modules on the CommandSTAR Lite's I/O communications bus. Since the console's I/O bus is RS-485, an RS-232 to RS-485 converter is required between the CHIB and the console.
CHIB Hardware Reference CTI Products, Inc. Theory of Operation The comparator generates the status signals. They are passed through the AIB or CIB module, through the MCN network, through the CHIB, the 485 converter, and into the console. 2.2 Comparator Controls The CHIB maps buttons on the console to the Force Vote and Disable controls on the comparator. The CHIB forwards the messages on to the AIB or CIB, which then pass the signals or messages to the comparators.

CHIB Hardware Reference CTI Products, Inc. 4.2 Option Switches Rear Panel Switches The rear panel switches are read by the CHIB only upon reset. The module must be power cycled or reset after these switches are set so that the options will take effect.
CHIB Hardware Reference CTI Products, Inc. 5. Connectors Connectors The NETWORK IN/OUT ports on the front of the CHIB are used to connect the CHIB with other MCN modules. These ports carry both the network data signals and the DC power for power distribution with other modules. Table 5 gives the pinout for these connectors. Figure 3 shows the location of pin 1 for each port. PRODUCTS, INC.

CHIB Hardware Reference CTI Products, Inc. Console Connections 7. Console Interconnection 7.1 RS-232 Connections with External Converter The CommandSTAR Lite console requires an RS-485 converter between the CHI module and the console. The following tables show the cabling that is required when using the CHIB module in RS-232 mode.
CHIB Hardware Reference CTI Products, Inc. 8. Addressing MCN Addressing with CHIB Modules Like any other module in the MCN family, the CHIB module must have a unique address on the network. 8.1 AIB or CIB Addressing Version 100 of the CHIB module uses a fixed address for its companion AIB or CIB module. It always looks for that module at Group 00 : Module 0. The AIB or CIB Module that is used with the CHIB module must be addressed at: Group 00 Module 0. 8.
CHIB Hardware Reference CTI Products, Inc. 8.3 Addressing MCN System Expansion The CHIB module and its companion AIB/CIB module can reside on an MCN network with other devices, as long as all MCN units have unique addresses and the AIB/CIB is addressed at 00:0. It is subject to the same limitations of a maximum of 20 CIB/AIB/IOB modules and a maximum of 64 modules total on one physical network. Multiple CHIB modules can reside on the same MCN network.
CHIB Hardware Reference CTI Products, Inc. 9. Console Configuration / Mapping Console Configuration / Mapping The CHIB module emulates 5 CommandSTAR Lite I/O boxes. The receiver status and control signals are mapped to the I/O Box points as shown below. Typical programming in CSDM Lite is shown in the rightmost two columns. Use I/O Type H. LEDs are programmed in pairs.

CHIB Hardware Reference CTI Products, Inc. 10. Remote Operation Remote Operation Because of the protocol between the CommandSTAR Lite console and the CHIB module, modem connection between the CHIB and the console is not supported. The CHIB must always be connected locally to the console (within the appropriate RS-485 or RS-232 distance limits). If display and control of a remote comparator is required, this can be done with standard MCN EXB Network Extender Modules.
CHIB Hardware Reference CTI Products, Inc. 11. Mounting Mounting Please refer to reference 1, Mounting Options, for details of mounting the CHIB 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.
CHIB Hardware Reference CTI Products, Inc. 12. Troubleshooting Troubleshooting This table is a list of troubleshooting tips specific to the CHIB module. 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 CHIB is treated as a field replaceable unit.
CHIB Hardware Reference CTI Products, Inc. PROBLEM Troubleshooting CAUSE Bad AIB to Astrotac cable Bad Astrotac 5. If using a CIB Bad connections to the comparator Bad CIB 6. Bad console I/O programming, firmware, or module Status Updates Okay Since status updates are okay, the links between the console and but no Force-Votes CHIB are okay. Also, the link between the AIB or CIB and the or Disables CHIB is okay (at least in the AIB/CIB to CHIB direction).
CHIB Hardware Reference CTI Products, Inc. Troubleshooting PROBLEM CAUSE presses. If you disconnect both the network and the serial cable from the CHIB, you should see a flash on this LED once every 4-5 seconds. If you see a different pattern than this with both the cables disconnected, the CHIB is bad.
