Kramer Electronics VP-128H Command RGB Mute delay, Status Inquiry for Crosspoints, Request **S

Communication Protocols

Changes in audio gains are NOT reported when Updates is turned on. Doing so would cause the router to send to the host long strings as panel operators turned up and down the volume. The query (?) command works for the A commands in the same way it operates on the X commands.

When the configuration message flags are both set to 000, the action of these gain commands is upon the audio channel connected to hardware level 3 and effected via level 7.

If there is more than one level with variable audio, possibly levels three and four, then a different configuration flag configuration if required and the A command must specify which audio path levels are being addressed.

M Command (RGB Mute delay)

Purpose: The M command is used to set the delay time for RGB ‘mute’ switching. It can be set to a different value for each output. This parameter is stored in non-volatile memory when the power is turned off. It is not stored in the individual setup registers.

Example:

**M3,5!! means switching on output bus 3 will have a 2.5 second mute delay.

The delay is in increments of 1/2 second. A value of 0 means there is no RGB delay mode and the RGBHV channels all switch together to the new source.

Like the A command the M command, with configuration flag values 000,000 operates levels 1 and 5 to achieve control of the RGB and HV channels.

For other configuration flag values, the M command may require the inclusion of which level is being controlled.

"S": Status Inquiry for Crosspoints

Request: **S!!

The command "S" requests that matrix status information be returned to the host. The reply from the router to the host is with a list of all outputs and all inputs connected to the outputs.

The number of lines of data in the list is equal to the number of outputs as set up by the Configuration command explained later.

The number of columns in the list is also set by the Configuration command. The configuration command determines the number of levels.
