Using 2408 to monitor DCC signal when controller is attached to PC by USB

Post by RAF96 »

I want to be able to monitor the DCC signal produced by my Hornby Elite DCC controller when it is running in conjunction with a software program on my PC. The Elite controller is in Comms with the PC by USB.
I am acutely aware of the Pico warnings about parallel grounds when a 2408 is also attached to the same PC by USB.
Previously I have monitored the DCC signal with the Elite controller stand-alone from the PC, i.e. operating manually not in conjunction with the model railway operating software.
Am I safe to have both the DCC controller and the 2408 connected at the same time to the same PC, as the monitoring of the software is next on my to-do list.

Hello RAF96, I am hoping you still get alerts from the Pico forum.

I too am trying to understand grounding in the operation of Picscope and USB. You say;

"I am acutely aware of the Pico warnings about parallel grounds when a 2408 is also attached to the same PC by USB".

Can you tell me where to find these Pico warnings?

Regards,
Martin.
