Backplane Bus Communication Velocity & Firmware Flash Compatibility
The IC695CMM002-AD interfaces directly with the RX3i backplane bus to ensure deterministic data exchanges between the host CPU and field serial devices. Up to six IC695CMM002 modules can be installed per rack, maintaining minimal backplane driver latency across all active serial streams. Firmware flash compatibility allows module upgrades to revision 1.32 or later, enabling software-configurable half-duplex flow control and enhanced diagnostic reporting for RAM, flash, and watchdog status.
Frequently Asked Questions
Q: Is the IC695CMM002-AD serial communications module hot-swappable during runtime?
A: Yes. The IC695CMM002-AD supports hot-swapping under power, allowing field technicians to replace the module without shutting down or interrupting the PACSystems RX3i backplane operations.
Q: What are the electrical isolation ratings between the serial communication ports and the RX3i backplane?
A: Isolation between ports, backplane, and frame ground is rated at 250 VAC continuous (1500 VAC for 1 minute), while port-to-port isolation is rated at 500 VDC continuous.
Field Installation Guidelines
Ensure the module is inserted vertically into an open RX3i backplane slot and firmly engaged with the rear chassis connector to establish proper grounding contact. Tighten the module locking screws to maintain vibration immunity and continuous frame ground continuity. Serial cabling connected via RJ45 interfaces must use shielded twisted-pair conductors. Shield braid must be bonded to earth ground at a single termination point to eliminate ground potential loops and prevent severe electromagnetic interference on RS-232/422/485 communication lines.
