Hello everyone!
I'm looking for any information concerning WAGO 750-920 Communications Cable - schematic or pinout + signal levels would be ideal (plan to build one).
Just got 750-816 unit with a handful of i/o modules from some dismantled equipment and like to use it to advance my PLC programming skills litle bit.
BTW: Is it the same cable as used with Beckhoff KS-2000 software?

Glad to hear this... But does anyone know enough about it to be able to build one from junkbox parts?lonzo wrote:hello,
it is nearly the same cabel as beckhoff.
My junkbox is pretty rich, of course, I can pull something starting from vintage military low inductance high power RF load resistor (with berillium oxide warning sign on top, brrr) to modern ARM-based microcontroller from there. And for sure, there is a lot of various RS-232 buffer chips and connectors.

Re: [?]: WAGO 750-920 Communications Cable pinout/signal lev
Can you please give us the pinout?
I suppose (from top to bottom) +5V, tx, rx, Gnd.
But i can't burn my fieldbus coupler trying...
Thanks,
GA

Found another pinout in my old notes:
TOP
--TxD
--RxD
--+5VDC
--GND
BOTTOM
Signal levels are TTL (0VDC/5VDC).
