GE IS200VCMIH2BCC Mark VI System Bus Master Controller Board

FAQ

Q1: What is the main function of IS200VCMIH2BCC?
A1: It serves as the bus master controller in the Mark VI system, managing communication between the controller, I/O boards, and the IONet network.

Q2: What types of communication interfaces are supported by IS200VCMIH2BCC?
A2: The module supports three 10Base2 IONet Ethernet BNC ports, one RS-232C serial port, and VME bus communication.

Q3: How are the internal power buses monitored?
A3: The system monitors +5V, +12V, +15V, and +28V buses, with alarms triggered when voltages deviate beyond configured thresholds.

Q4: Why is the alarm threshold for the +28V supply different?
A4: The +28V alarm threshold is ±5.5% to accommodate higher voltage fluctuations and minimize false alarms.

Q5: What memory types are included in IS200VCMIH2BCC?
A5: The module includes 32KB dual-port memory, 256K x 32 SRAM, and flash memory (either 512K x 8 or 4096K x 8).

Q6: How does the module interface with the PDM for diagnostics?
A6: Through the J301 connector, it receives signals for P125V fault conditions, analog inputs, and digital diagnostics.

Q7: How does VCMI manage the boards in the system rack?
A7: It assigns and manages IDs for all boards and terminal blocks to ensure accurate configuration and diagnostics.

Q8: What is the function of the RS-232C port?
A8: It provides a serial communication interface for external device configuration, diagnostics, or data transfer at 9600 baud.
