Verifying Signal Status
8
Instruction Manual – BCS Basic Control Structure Protocol
Verifying Signal Status
Switch status can be checked to confirm that the switch has executed correctly or to confirm correct
routing to multiple outputs. Digital output volume status (see page 15) and digital input gain status
(see page 18) can also be verified. The characters and numbers in a Status command tell the system
which input or output to verify on which level. A Status command has successfully executed when the
entered “
T
” appears followed by the result of the status query in parenthesis. Empty parenthesis
(
)
indicate that the input or output specified is not routed on the specified level. For status response
examples responses, see below.
Fragmented status results (see page 9) are available for systems that support this feature. Fragmented
Status Reporting
must
be enabled in XNConnect before valid fragmented results can be returned (see the
XNConnect Help file).
General Rules for Verifying Status
Multiple inputs, outputs, or levels cannot be entered in a Status command.
If the level is not specified in the Status command, the command is executed on the default
level, which is normally Level 0 (e.g.,
SI83T
verifies the routing status of Input 83 on
Level 0).
If you check the status for an input or an output on an audio-follow-video level and only the
video or the audio is routed on that level, the result will come back as not routed, unless the
system supports fragmented status reporting.
Important:
If the level is not specified in a BCS command, the command is executed on the default
level (normally Level 0), which is defined in the configuration file. If the level is omitted and the
BCS command executes on an unexpected level, check the default level in the configuration file
(for systems without a configuration file, check the product documentation).
To verify signal status:
1.
Enter the Status command below. Replace the “
#
”s with the level and input number or the level and
output number.
SL#I#T
or
SL#O#T
The results of the BCS command will display in parentheses; empty parentheses (
) indicate that no
input is routed to the output being verified or that no outputs are receiving a signal from the input
being verified.
