For procurement and specification due diligence, engineers frequently search for phrases like “used in industrial automation,” “applicable in control systems,” and “RX3i serial communications module,” with the model name highlighted for quick identification. The IC695CMM002-BF thus represents a proven, scalable solution for expanding serial connectivity in GE Fanuc RX3i deployments.

Product Introduction & Positioning
The IC695CMM002-BF is a RX3i serial communications module designed to add two independent RS-232/RS-485 ports to a PACSystems RX3i CPU backplane. It slots into the RX3i backplane and provides isolated serial channels, enabling robust data exchange with devices and networks beyond the main processor’s direct reach. The module supports both RS-232 and RS-485 / RS-422-style signaling, including full- and half-duplex configurations, with pluggable flow-control options and configurable baud rates to match a wide range of field devices. This module’s value lies in its ability to extend the RX3i system’s communication fabric without adding significant software complexity, while maintaining clean signaling and reliable diagnostics. The model name is a clear beacon for procurement and service, ensuring compatibility with other RX3i components, software tools, and support resources. In short, the IC695CMM002-BF is a compact, standards-aligned serial communications bridge that enhances the reach and versatility of RX3i control networks.

Key Technical Features & Functional Benefits
The IC695CMM002-BF emphasizes two high-impact traits: versatile serial connectivity and robust isolation. With two independent ports, it supports a variety of serial protocols, data rates, and addressing schemes, enabling integration with a diverse set of field devices and third-party equipment. Hardware design prioritizes reliability in harsh industrial environments, including galvanic isolation between ports and the backplane to reduce ground-loop risks and protect the CPU from transients. The module’s RS-232/RS-485/RS-422 versatility allows both legacy and modern devices to co-exist on the same RX3i network, simplifying migration paths. Compatibility with the RX3i backplane ensures straightforward integration with RX3i processors, I/O modules, and software tools for configuration and diagnostics. Long-term reliability is aided by solid crosstalk suppression, stable power rails for the ports, and a proven track record in mission-critical automation projects. Overall, the IC695CMM002-BF offers the right mix of flexible serial connectivity, ruggedness, and ecosystem compatibility that engineers need for scalable, dependable RX3i deployments.

Installation Notes & Maintenance Best Practices
Before installation, confirm the RX3i chassis supports the IC695CMM002-BF in the intended backplane slot and verify any region-specific wiring conventions for RS-232/RS-485 signaling. Plan cable routing to accommodate two ports without interference with power or I/O cabling, and ensure proper termination and biasing schemes are in place for RS-485 lines to minimize reflections. Grounding and shielding should follow standard facility practice, with clear channel labeling to support future diagnostics. During maintenance, inspect port connectors for wear and verify port LEDs (if provided) indicate normal activity. Validate baud rate configurations and protocol settings via the RX3i software tools, and keep firmware compatibility in mind when performing upgrades across RX3i components. Maintain an inventory of commonly used serial cables and RS-485 terminators to minimize downtime during expansion or maintenance cycles.
