AXB-VOL3 Send_Commands

PLT

 Ramps specified channel(s) from current level to a specified preset level or percentage at the 
current rate or optionally in a specified amount of time.

Syntax:

SEND_COMMAND VOL, ’P<output channel 0-3>L<level 0-255|0-100%>[T<Time 

0-255 in tenth second increments>]’

Variables:

Output Channel = Channel numbers 1, 2 or 3. Output channel 0 = both channels 1 and 2.

Level = Level number (0-255) or percentage (0-100 percent). Level 0 is lowest volume (same 
as mute) and 255 or 100% is maximum volume.

Time = Optional ramp time (0-255) in tenths of a second.

Example 1:

SEND_COMMAND VOL,'P0L50%'

Ramps both channels to 50% mid level volume at the current ramp rate.

Example 2:

SEND_COMMAND VOL,'P1L255T20'

Ramps channel 1 to highest level volume in 2 seconds.

PR

Sets the ramp rate of the specified channel(s) where the time is the time to ramp the full range 
both down to up and up to down or optionally just down to up or just up to down.

Syntax:

SEND_COMMAND VOL, 'P<output channel 0-3>R<ramp rate 0-255 in tenth 

seconds>[U|D]'

Variables:

Output Channel = Channel numbers 1, 2 or 3. Output channel 0 = both channels 1 and 2.

Ramp Rate = Sets ramp rate (1-255) for channel commands in tenth second increments.

U = Optional character sets rate for ramp up.

D = Optional character sets rate for ramp down.

Example 1:

SEND_COMMAND VOL, 'P0R50'

Sets ramp rate of channels 1 and 2 to 5 seconds full range from down to up and up to down.

Example 2:

SEND_COMMAND VOL, 'P3R50D'

Sets ramp rate of channel 3 to 5 seconds full range from up to down only.
