Interface Description:
<L input fire line
<N input zero line
>N zero line output (actually connected directly to the output)
>LNO Firewire output (normally open, dynamic output)
>LNC FireWire output (normally closed, dynamic output, generally not connected)
Note: “ON” in the function description refers to the connection between “common” and “normally open” of the relay, that is, the output of the moving contact.
