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:ø The AC power has been applied. (x.xx is the software version number.)

RECONFIG

A changeøhas 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.
