Protocols and pin assignments are defined in other specifications.

Even though this circular connector was largely standardized, there was no industry standard for pin assignments.

Owing to differences in pin assignments and circuit interfacing, the 8563 and 8568 are not electrically interchangeable.

D-sub connectors follow another rule for pin assignment.

Both Type 1 and Type 2 have this common feature set and pin assignments:

It uses the regular 68-contact pin assignment.

Common problems were non-standard pin assignment of circuits on connectors, and incorrect or missing control signals.

The following table lists commonly used RS-232 signals and pin assignments.
