We have a ThinkLogical Serial Console Server that I'm attempting to connect to some F5 Big IPs. Both devices have RJ45 jacks, and I'm trying to get them to talk to each other. The Big IPs came with TIA 568B to rollover adapters.

Connecting using RJ45 -> DB9 works just fine.

I've tried connections between the SCS and Big IPs with the following, in all permutations:

• With and without the adapter. EDIT: Meaning with rollover and standard pinout ethernet cables.

• DTE and DCE on the SCS.

• Multiple baud rates on both sides.

Nothing has worked, so I can only conclude that the pinout is the problem. Does anyone know the correct pinout that I should be using? My google fu has failed me.

EDIT: Just in case someone finds this while searching for the same problem, here's the answer: my coworker accidentally used an F5 failover cable instead of standard ethernet. The failover cables have their own unique pinout, so they didn't work. The correct cable for this job is a standard rollover, or a standard ethernet cable with a rollover adapter (which is included with the Big IPs).

We also had to change our serial console server from DCE to DTE, turn off all flow control, and (obviously) match baud rates and parity on both sides. The Big IPs default is 19200 8N1.
