Short post – needed to reset password on a APC PDU. Only way to do this was getting a console cable, of cause this cable is a proprietary cable of APC and not within my reach when you need it.
So found the pinout and did a little DIY. Pinout is as in the table
APC RJ12 Pin | DB9 Pin |
1 Not used | 1 |
2(GND) Yellow | 5 (GND) |
3 Green | 2 (RX) |
4 Red | 3 (TX) |
5 (GND) White | 5 (GND) |
6 Not used | 1 |
