C620 to M3508 7-Wire Encoder #5

Open pknessness opened 2 years ago

pknessness commented 2 years ago

I'm looking to decode the protocol for the 7 wire encoder cable between the C620 and M3508. How would I go about doing that?

Take some samples. https://usd.saleae.com/products/saleae-logic-8

Is there any way to do this by looking at the firmware?

I'm concerned I'm going to be unable to decode solely by using a logic analyzer
