7i76e and 7i73

Murphy's law. You are good!

In deed, The cable has other colour distribution. Grrr.
Now i remember having read that there existed another norm..

One LED is red. Hope i did not grilled the card.

Will change the plug.
Thx

I dont think i've seen any non EIA cables but have heard they exist...

Not likely anything was damaged (hard to do with just 5V)

24V wiring is another matter...

The red LED is expected if you have power but no communication (it signals a watchdog fault)

Made a new plug on the old cable.
Restarted and now i see pins!

THX

Now i can work on transfering from 7i47 to my new electronics.
Also 7i47 never let me down.

Great, glad you got it going

I know this is an aged topic but I'm facing the same problem.
I connected my brand new 7i73 on my 7i76e with two different network cable and still getting communication error after trying these steps :

• wire as explained in 7i73 manual
• swap Tx+/Tx-
• swap Rx+/Rx-
• swap Tx/Rx
• swap Tx+/Tx-
• swap Rx+/Rx-
  
  I switched off 7i76 between each test but didn't started LinuxCNC.
  I guess hardware communication between 7i76e and 7i73 don't need LinuxCNC to be started, am I wrong ?
  
  My hal file contains sserial_port_0=20xxxx.
  
  Does anyone have an idea on what I'm doing wrong ?

1. The picture shows the TX and RX pairs swapped
(go by the colors in the 7I76 manual)
2. You need to start LinuxCNC for communications to be initiated
