GE CPMC1303 Transition Module

The GE CPMC1303, also cataloged as the CPMC1303 Transition Module, operates as a dedicated hardware component for rear-panel I/O signal routing and external device interface execution within CHAMP-based high-density platforms.

Hardware Specifications

Industrial Control and Network Architecture

• Backplane Bus Communication Velocity The transition module establishes an immediate physical bridge from the host R15-AMC backplane pins to external data networks. By utilizing a high-density CHAMP 0.8 mm latching plug interface, it maintains path integrity and impedance matching required for high-velocity signal transmission without introducing processing latencies.
• Profinet / EtherNet/IP Deterministic Networks The hardware layout provides a clear physical breakout route for legacy and deterministic networks alike. Its secondary discrete cable assemblies and the high-density DB50 female connector terminal permit concurrent routing of serial, discrete, and deterministic communication frames alongside sensitive avionics data paths.
• I/O Density Scaling and Physical Routing The structural harness configuration breaks down bundled high-density chassis lines into eight isolated 10-inch channels terminated with 3-lug CJ70 twinax 1553 cable jacks. This design handles physical footprint restrictions by offloading heavy interconnection loads directly to the rear panel boundary, preventing internal slot overcrowding.

Frequently Asked Questions

Q: Can the CPMC1303 module be hot-swapped while MIL-STD-1553 data bus traffic is actively transmitting?

A: No. While the hardware itself is a passive mechanical interconnection assembly, disconnecting or connecting the CHAMP 0.8 mm latching plug or individual twinax leads during live data transmission alters the bus termination impedance, causing signal reflection and immediate data corruption across the active network.

Q: What is the purpose of the 3-lug configuration on the CJ70 twinax cable jacks?

A: The 3-lug bayonet coupling design provides precise mechanical keying and secure physical interlocking. It prevents accidental decoupling caused by low-frequency structural panel vibration and distinguishes the MIL-STD-1553 multiplex data bus lines from standard 2-lug BNC video or RF test connections.
