Polling Notes:
Note 1 – Base-Zone Commands:
The Base-Zone-related commands will only return a message if the specified rbz parameter is zero, or matches the
programmed Base-Zone in the switcher configuration.
When both video-only and audio-only switchers have the same base-zone (eg: LE-1600A and LE-1600V), the
video switcher sends the message slightly after the audio switcher.
In an installation with multiple daisy-chained switchers, the messages from different switchers are delayed so there
are no collisions – a single command using rbz=0 will yield messages from all switchers on the daisy-chain.
Note 2 – System-Information Message (!S,100):
The SysInfo message is sent in response to a *CR,100,rbz polling Command, and is also sent at system boot. It
provides the switcher's base-zone, family/model, and the protocol level (the first 2 digits of the firmware version).
Note 3 – System-Detail Message (!S,102):
The SysDetail message is sent in response to a *CR,102,rbz polling Command, and is also sent at system boot.
It provides the switcher's base-zone, number of zones, number of sources, switcher-type, and the full firmware
version. This command is very useful for determining the entire switcher configuration -- by sending the
*CR,102,0 command at startup, the control system will receive messages from all switchers on the daisy-chain,
and can determine total zones of audio, video, etc.
Note 4 – Read-Acknowledge Command:
The Read-Acknowledge command may be used to poll for existence of switchers (with less complexity than polling
with the SysInfo or SysDetail commands).
This command is also useful in programs where you issue potentially lengthy commands (eg: multiple routes or
Preset-State changes), and wish to wait for completion – you may issue a Read-Acknowledge command, and
wait for the response before continuing in your control program.
Note 5 – Read-Group Commands (*CR,80-88):
The Read-Group commands will only return a message if the specified gbz parameter matches the programmed Base-Zone
in the switcher configuration. Unlike the other group commands, these include all eight zones starting at gbz.
The Read-Group Commands return 8 parameters starting at Base-Zone (ie: params for bzn, bzn+1…bzn+7).
For a 4-zone switcher, the last four parameters are 255 to indicate that they are not applicable. For a 16-zone
switcher, two messages are returned: the first message starts at Base-Zone (params for bzn, bzn+1…bzn+7),
and the second message starts at Base-Zone+8 (params for bzn+8, bzn+9…bzn+15).
