The IC693CBL300 expansion cable preserves high backplane bus communication velocity across multi-rack baseplate setups by providing low-impedance parallel routing for high-speed I/O scan traffic. The integrated continuous cable shield minimizes high-frequency electromagnetic interference (EMI) and cross-talk, preventing bit errors across the 25-pin expansion bus. By maintaining signal rise times and propagation delays within exact Series 90-30 timing tolerances, the cable preserves deterministic backplane bus updates and ensures stable firmware execution across all expanded I/O drops.
Q: How does the dual-connector end on the IC693CBL300 support multi-rack expansion?
A: The second end features a two-headed Wye configuration containing one male and one female 25-pin D connector. One connector plugs into the baseplate expansion port while the second acts as a pass-through tap to daisy-chain to the next rack expansion cable.
Q: Is external grounding required for the IC693CBL300 cable assembly?
A: Continuous grounding is established through the metallic backshell of the 25-pin D connectors when securely fastened to the grounded baseplate expansion ports. No separate grounding pigtail is required.
Q: What is the maximum number of IC693CBL300 cables that can be connected in a single system?
A: The total count of expansion cables depends on the specific Series 90-30 CPU model and its maximum supported expansion rack limit, adhering to the overall backplane distance allowance specified by the CPU system architecture.
