Automation Protocol Passive Mode Commands

Passive Mode Commands
Passive mode is a mode of operation where the Imagestore will transmit its
internal state via the automation port when something has changed. In this
mode, the amount of polling required by external automation devices will
reduce, as it enables them to listen to the Imagestore tallies to always have an
accurate image of the system status.
Set Passive Mode On/Off Ya
This command switches passive mode on or off within the Imagestore.
CMD Param_1
Ya %01x
0=mode off, 1=mode on
Set Passive Mode Transmission Interval Yb
This command determines the interval (in milliseconds) at which the
Imagestore 2/3 will check its internal state before relaying information to the
outside world via automation.
CMD Param_1
Yb %04x
Interval duration (ms)
The default value is 500ms (1/2 second, 0x1F4). Once this value has been
changed it will be saved in the Imagestore state file for subsequent use.
Note: This command is only valid for Imagestore 2/3, or for
Imagestore 300/HD-TV operating with an Easysound
standalone. Later Imagestore products do not support this
command because they are able to transmit state tallies every
field/frame.
