• Supports up to 256 nodes per network.
• High-speed 2.12 Gbaud fiber-optic communication via LC connectors.
• Supports hot insertion and removal (hot-swappable) for maintenance without system downtime.
• Configurable network parameters with integrated error detection.
• Compatible with RMC128 and RMX228 modules.

Technical Specifications

Installation Guidelines

• Ensure the RX3i rack is powered down before installing or removing the module, unless the system specifically supports hot-swapping in the current configuration.
• Handle the module by the edges to avoid ESD damage to sensitive electronic components.
• Ensure fiber-optic cables are clean and properly seated in the LC connectors to prevent signal attenuation.
• Maintain proper ventilation within the control cabinet to prevent overheating of the RX3i rack components.
• Verify that the module is fully seated and the locking mechanism is engaged before applying power.

FAQ
