Attaching 4T Port Adapter Interface Cables
On a single 4T port adapter, you can use up to four synchronous-serial connections.
Connect serial cables to the 4T port adapter as follows:
Step 1 Attach the appropriate serial cable directly to the receptacle on the 4T port adapter and
tighten the strain-relief screws. (See Figure 30.)

Caution
Serial interface cables must be attached correctly or damage to the cable plug will result.
Attempting to force a cable plug on the 60-pin receptacle can damage the plug. (See Figure 31.)

synchronous-serial equipment and tighten the strain-relief screws.
