Re: Jaguars not passing CAN communications

I have four black jaguars i want to include in my network. Right now I can only see one jaguar at a time. I am able to communicate with all four Jaguars individually but if I try to chain two together i only see the first in the chain.

Can you post a link for that thread here? It may be helpful to me.

I made the cable to connect the rs232 port to the first black Jag. I included the terminating resistor in the CAN plug end of the cable instead of in the RS-232 plug. The cable is probably 2 or 3 feet long. Do you think this could be causing the issue i described above? I can explain my cable construction more clearly if required..
