Adding a GD40 carbon monoxide detector to my D180 &HS34 panel. The GPS is connected to the HS34. What is the best connection for the RS232 from/to the GD40 please?
There seems to be options through the EMS and EFIS connectors.
It looks like the gd40 has a relay that goes to ground when an alarm activates. You should be able to connect this lead to pin 9 or 10 on the EMS D37 connector and configure the contact. That should get you a visual alarm on the EMS screen. Hopes this helps. Bob
