Hi,

I made a cross over X21 in order to connect two routers back to back.

router-----Male X21----Converter-----Male X21------Router

I have some trouble and I would like to be sure of my cabling.

Please, can someone have a look at my converter?

Here is the converter using two pin15 female connectors:

1--------------shield GND------------------1
2--transmit + -------------receive + ------4
3--control + ---------------indication + ---5
4--receive + ---------------transmit + -----2
5--indication + ------------control + -------3
6------------------timing + ---------------------6

8---------------control GND ------------------8
9--transmit - ---------------receive - -------11
10--control - ---------------indication - ----12
11--receive - ---------------transmit - ------9
12--indication - ------------control - --------10
13-----------------timing - ----------------------13


Thank you.

Regards,

Christophe
