Greetings,
I'm wiring up the panel, and noticed that the SL-40 has an RX, TX, and signal ground for the RS232 communications. The 496 only has a data out, and no "data ground". For that matter, none of the other serial devices have a signal ground either.
I'm guessing that most devices reference the data to ground internally, but perhaps some devices like the SL-40 leave the signal ground floating. My plan is to connect this signal ground cable to "ground" on the plane, and figure that all devices will be using that as a reference.
Anyone see a problem with this? If so, type fast, because I'll be wiring this up in a couple hours
Cheers,
Rusty
