Backplane Bus Communication Velocity and Signal Integrity

The IC693CBL302 preserves deterministic backplane bus communication velocity across long distances up to the maximum 15-meter limit for expansion baseplates. By embedding internal termination resistors within the end connector, the cable eliminates high-frequency signal reflections and bus noise that cause erratic data frame transfers. This continuous shielding architecture protects parallel data lines from severe industrial electromagnetic interference, maintaining strict signal timing and full firmware flash compatibility across all connected Series 90-30 expansion racks.

Frequently Asked Questions

Q: Can the IC693CBL302 cable be used in the middle of a multi-drop expansion chain?

A: No. The IC693CBL302 contains built-in termination resistors inside its end connector and lacks a pass-through port, meaning it must only be used as the final cable link at the end of the expansion bus chain.

Q: Is hot-swapping or disconnecting the IC693CBL302 cable while system power is active permitted?

A: No. System power must be fully de-energized prior to connecting or disconnecting the IC693CBL302 cable to prevent electrical transients and physical hardware damage to the expansion bus interface circuitry.

Q: How many total expansion cables can be deployed with Series 90-30 CPUs?

A: Series 90-30 CPUs ranging from CPU 350 to CPU 374 support up to 7 expansion cables, whereas CPU models 331 through 341 support a maximum of 4 expansion cables.

Field Installation Guidelines

De-energize all primary system power supplies supplying the main CPU baseplate and downstream expansion or remote racks prior to installation.
Connect the single 25-pin male D-sub connector on the CPU end to the expansion port located on the right side of the CPU baseplate or the open port of a preceding Wye cable.
Route the 15-meter continuously shielded cable through dedicated cable trays separated from high-voltage AC conductors and drive wiring.
Plug the terminated 25-pin male connector on the opposite end into the female expansion port on the left side of the final expansion baseplate in the link.
Secure all connector retaining thumb-screws tightly to provide low-resistance frame grounding and prevent physical disconnection due to field vibration.
