Maintenance and Troubleshooting
Ensure that settings are returned to X so relay closures are controlled from the uplink. If this
does not occur, the relay closures will remain in the state specified by the CO command.
CQ
Relay Contact Query
Syntax:
CQ ?
This command queries the receiver for the physical state of the relay contact closures. The value returned is an
eight-character value, each character representing the status of an individual relay. A 0 for a relay indicates the
relay is open, a 1 indicates the relay is closed. The first character corresponds to receiver relay contact 1, the last
character corresponds to relay 8.
CS
Relay Contact Sense
Syntax:
CS string
CS ?
Front Panel:
Interfaces > Relays >
Relay Number: <enter 1 – 8>
Sense: <Normally Open, Normally Closed>
This command controls the normal (deactivated) position for the control relays. The string is a character string,
with each character position controlling the normal state of a single relay. The first character position controls
relay 1, the last character controls relay 8. An individual 1 character indicates the relay is normally closed and that
the relay is activated by opening it. An individual 0 indicates the relay is normally open and that the relay is
activated by closing it.
The default value for CS is 00000000 (all normally open).
