RGB 320-Initiated Messages
When a local event takes place, such as a front panel operation, the RGB 320
responds by sending a message to the host. These RGB 320-initiated messages
are listed below.
(C) COPYRIGHT 1997, EXTRON ELECTRONICS RGB 320, VX.XX
Power-on message:
The AC power has been applied. (x.xx is the software version number.)
RECONFIG
A change has been detected: from the front panel or from an RGB 322/324/340
buffer, a change in scan rate frequency has been detected, or an operation has
occurred that requires a new memory block to be written. No response is
expected from the host, but, for example, the host program may want to request
new status (I or i command).
Ci or Ai or Vi (where “i” is the input channel number)
The input has just been switched. A=audio; V=video; C = both audio & video.
