GE Fanuc IC695CMM002 PACSystems RX3i Serial Communications Module
Configured for isolated serial connectivity in industrial automation networks, the GE Fanuc IC695CMM002 (IC695CMM002 Serial Communications Module) provides direct physical/electrical execution. The module resides in a PACSystems RX3i universal backplane to exchange data between legacy edge devices and the host controller. It manages protocol execution locally on two independent channels, relieving the central processing unit of communication overhead. The hardware interface adapts to multiple differential and single-ended signaling standards via software configuration.

Backplane Bus Communication Velocity and Firmware Compatibility
The module utilizes high-speed backplane bus communication velocity pathways within the PACSystems RX3i backplane to transfer data packets without introducing deterministic network jitter. Firmware flash compatibility determines protocol performance limits; advanced operational parameters, including DNP3 precise timestamp synchronization, require host CPU firmware version 5.00 or higher. The internal circuitry uses logic-level shifting to bridge the backplane parallel bus structure to the serial transceivers, ensuring stable I/O density scaling when multiple communication processors reside in the same rack assembly.
Frequently Asked Questions
Q: Does the module support hot-swap operations within the RX3i backplane?
A: Yes, the module supports Hot Insertion and Removal (HOT-SWAP) into an RX3i universal backplane, provided that the backplane is powered by an RX3i power supply that remains stable during the transient current draw.
Q: How is the built-in 120 Ohm line termination engaged for RS-485 networks?
A: The internal 120 Ohm termination resistor is selected via software configuration settings within the programming software utility, eliminating the need for external hardware jumpers or physical termination blocks on the RJ-45 connector.
Q: Can standard commercial RJ-45 patch cables be used for connection to standard Modbus devices?
A: No. The port features a custom pinout configuration specific to GE Fanuc serial signaling. Standard Ethernet or commercial Modbus RJ-45 cables will misalign data and power pins, requiring custom fabricated cables or specific termination adapters.
Field Installation Guidelines
- Shield Grounding and Noise Suppression: All long RS-485 and RS-422 serial cable runs must employ twisted-pair shielded cable configurations. Ground the cable shields at a single point, preferably at the chassis ground terminal of the RX3i backplane rack, to suppress electromagnetic interference and prevent ground loop currents across the isolated ports.
- Physical Mounting Constraints: Insert the module only into universal backplane slots (IC695CHS007, IC695CHS012, or IC695CHS016). Align the module with the top and bottom chassis guides, then press firmly until the module clicks into the backplane connector before engaging the retention screws.
- Pinout Alignment and Mechanical Strain Relief: Verify custom cable wiring diagrams against the official product manual pinout map before applying power. Secure serial communication cables using external strain relief bars to prevent mechanical stress on the RJ-45 female connectors.
