Status

 

 

This query is sent to the online modem of a 1:1 pair. It

 

 

 

 

 

 

provides access to the fault status information (FLT?) of

 

 

 

 

 

 

the offline modem. This is the only way to interrogate the

 

 

 

 

 

 

status of an offline modem at the distant-end of a link.

 

 

 

 

 

 

The response format may be:

 

 

 

 

 

 

No1for1 which indicates that no 1:1 system has been

 

 

 

 

 

 

detected. Presence of a 1kHz signal from the CRS-150

 

 

 

 

 

 

is used to indicate a 1:1 set-up.

 

 

 

 

 

 

NoComm which indicates that a 1kHz signal has been

 

 

 

 

 

 

detected, but that there is no (or not yet) a response for

 

 

 

 

 

 

the modem.

 

 

 

 

 

 

abcdef would be the FLT? response information from

 

 

 

 

 

 

the offline unit.

Switch

 

 

 

(message

 

 

 

 

 

Forces the unit to toggle the Unit Fail relay to the “fail”

ok)

 

 

 

 

 

state for approx 500ms. If the unit is a 1:1 pair, and it is

 

 

 

 

 

 

currently the ‘On-Line’ unit, this will force a switchover,

 

 

 

 

 

 

so the unit will then be in ‘Standby’ mode. The command

 

 

 

 

 

 

is always executed by the unit, regardless of whether it is

 

 

 

 

 

 

stand-alone, in a 1:1 pair, or part of a 1:N system.

 

 

 

 

 

 

This command takes no arguments.

 

 

 

Note: The following codes are used in the ‘Response to Command’ column:

=Message ok

?Received ok, but invalid arguments found

*Message ok, but not permitted in current mode

# Message ok, but unit is not in Remote mode
