Supvervisor Eng. III, RJ45 to DB9 adapter pinout...

Unanswered Question
Mar 4th, 2007

Does anyone know what the pinout is supposed to be on the RJ45 to DB9 adapter? I've tried pinning it to a general config I find on other sites, but when I use it with a standard Cat5 cable, I get no communication with the supervisor III engines on two different switches.

I do know the proper settings for the com port and have it set. I feel the adapter is the issue, and want to make sure it's pinned correctly.

Thanks!!

I have this problem too.

THe pin-out spec is for a "Rolled" cable:

pin1 --> pin8

pin2 --> pin7

pin3 --> pin 6

(and so on)

Standard jumpers are going to be straight-through (1->1, 2->2, 3->3, {etc})

Here's a link for the console pinouts ...

THe COM port should be 9600, none, 8, 1 (and *NO* hardware or software handshake). It can be changed, but default is as above.

Good Luck

Thanks for the replies guys! I may end up doing just that, buying the adapter and cable. The only adapters sold in/around Kansas City are the unfinished type and if you don't get the exact color to number pinouts right, you trash the adapter.

Thanks again!
