Serial Redundancy Communication
The IC697RCM711 uses two serial ports for redundancy communication between the associated control hardware. Its communication interface uses a non-isolated differential electrical method, while the specified effective data rate reaches 500 Kbytes/sec.
The module provides separate LED indications for local and remote states. Therefore, technicians can distinguish overall module status from local and remote readiness or activity conditions. The specified IC600WD005, IC600WD010, IC600WD025, and IC600WD050 cables provide compatible communication connections. For terminated connections, GE specifies the IC697CBL811 and IC697CBL826 cable assemblies.
Frequently Asked Questions
Q: How many serial ports does the IC697RCM711 provide?
A: The IC697RCM711 provides two serial communication ports.
Q: Is the communication interface electrically isolated?
A: No. The supplied specifications identify the interface as non-isolated differential communication.
Q: What LED states does the module provide?
A: The module provides OK, Local Ready, Local Active, Remote Ready, and Remote Active LED indicators.
Field Installation Guidelines
Install the IC697RCM711 in its designated single Series 90-70 rack slot and secure the module according to the rack hardware requirements. Before connection, verify that the selected communication cable matches the specified interface and termination arrangement.
Route communication cables separately from high-voltage power conductors and high-current switching circuits where practical. Maintain proper cable shielding and grounding according to the cabinet grounding scheme and the applicable Series 90-70 installation practices.
Because the interface uses non-isolated differential communication, avoid unintended ground paths between connected equipment. Check connector seating, cable routing, and termination before applying system power.
After installation, use the five status LEDs to verify the module state. Check the local and remote Ready and Active indications during commissioning to confirm the expected communication condition.
