I have an APC Rack PDU (AP7920) and a Lantronix ETS16P RS232 terminal server. I would like to connect the RackPDU directly to the Lantronix. The RackPDU has a serial RJ12 connector and the Lantronix a serial RJ45 connector. I found pinouts for RackPDU and Lantronix.
This is the connection I came up with:
However, after crimping the cable, the connection did not work (regardless how much I was typing in the Lantronix, there was no response from the APC).
Is this the right connection? Do I miss anything?
Are the TX- and RX- indeed GND?
