A question for you RS-232 experts...
I'm driving the GPS input on my ACK E-04 ELT from a GTN-650 RS-232 serial output - shielded Data Out and Data Ground lines with the shield tied to the connector backshell. The ACK connector has Power, Data In/Out and Airframe Ground connections.
The power and -650 Data Out to ELT Data In pins are straightforward, but is the -650 Data Ground tied to the ACK Airframe Ground? Is the line shield tied to Airframe Ground as well?
Thanks in advance for your help...
Dave
