Could be lots of things going wrong - Most probable communication has gone due to fault RS-232 chips on the Mux

Hello, I got the same mux as the one posted on first page and I'm wondering if its correct that the U103 and U107 should both be MAX232? Are there no RS485 tranciever?

HI again !

I found the sheme to conect diretely to the pcb of the C3 !
Only 8 wires use in COM port pins 2-9, pin 1 is not use, and pin 9 must be conected with pin 4.
Pinout of 10 pin for round cable:
1 - GND (to pin 5 COM)
2 - Vcc to adapter
3 - Tx+
4 - Tx-
5 - Rx+
6 - Rx-
7 - to pin 6 COM (DSR)
8 - to pin 7 COM (RTS)
9 - to pin 8 COM (CTS)
10 - to pins 4,9 COM (DTR,RI)

Do not use pin 2 (Vcc), find wire to pin 14 U107 and conect to pin 2 COM (RX),
find wire to pin 13 U107 and conect to pin 3 COM (TX)

but here in the midle box o the cable is diferent !

see midle pic of post before
