Features:
- Extends single-mode reflective-memory links to the supported 10 km distance.
- Creates a direct two-node optical path for RX3i CPU redundancy.
- Replicates configured network address regions without CPU-managed copying.
The single-mode transceiver distinguishes IC695RMX228 from the multimode RMX128 when plant distance or installed fiber determines the selection.
In a dedicated redundancy path, the primary and secondary units form a closed LC fiber ring with no hub or extra reflective-memory node.
A general reflective-memory network may contain many compatible nodes, but mixed optical media requires a compatible hub that preserves the required optical conversion and ring path.
General Electric IC695RMX228 PACSystems RX3i 128 MB Single-Mode Redundant Memory Xchange Module is available for Apter Power quotation and official-documentation support.

IC695RMX228 Single-Mode Optical Path
- Reach: Use the specified single-mode fiber for links up to 10 km.
- Polarity: Connect each LC transmitter to the receiver of the next node in the ring.
- Mixed media: A compatible hub is required only when a general reflective-memory ring combines single-mode and multimode nodes.
- Connector care: Keep LC end faces capped, clean, and within the permitted bend radius.
IC695RMX228 Redundancy Link Rules
- Pairing: A CPU redundancy path uses one RMX228 in the primary unit and one in the secondary unit.
- Topology: The redundancy path is a direct two-node ring with no hub or additional reflective-memory node.
- Link count: Emerson recommends two independent redundancy links when the system architecture permits four RMX modules.
- Transfer mode: Optional redundant transfer sends protected network traffic to reduce the chance of a dropped packet.
IC695RMX228 Replicated Memory Operation
- Propagation: A write at one compatible node updates the corresponding address at every node in the reflective-memory ring.
- Packet sizing: The module selects transfer packets dynamically from 4 to 64 bytes.
- Address segmentation: Configurable offsets assign nodes to 16 MB regions of the network address space.
- Events: Four network interrupts carry 32 data bits each, in addition to the programmable module interrupt.
IC695RMX228 Main-Rack Integration
- Bus location: The module requires a PCI position in an RX3i Universal Backplane main rack.
- Rack population: A main rack accepts up to six CMX/RMX modules in total, with no more than two configured as redundancy links.
- Power calculation: Include 580 mA at 3.3 VDC and 220 mA at 5 VDC in the rail-by-rail load check.
- Powered service: Follow the RX3i hot-insertion sequence and grounded ESD procedure before handling the optical housing.
