10.4.7 Lock Change
Format: [0x02] [Unused] [Output] [Locked]
Each output has an associated lock state, which is a logical bit used by single
bus remote panels to disable front panel input selection. The lock affects all
levels, so only the output is required to set the lock. Set the ‘Locked’ byte to 0
for unlock; or 1 for locked.
10.4.8 Crosspoint Change
Format: [0x03] [Unused] [Output] [Input] [Level(s)]
The crosspoint change command can be used to switch a specified output to a
specified input on one or more levels. The levels are bitwise, meaning that bit
1 represents level 1 and bit 2 represents level 2. After receiving this message,
the frame will automatically broadcast an updated crosspoint status update
message to all remote clients.
10.4.9 Volume Increment / Decrement
Format: [0x06] [Unused] [Modifiers] [Index]
The volume increment / decrement command adjusts an input or output audio
gain up or down by one step on the left, right, or both sides. The lower 4 bits
of the modifiers byte is used to set all parameters of the command (see
below). The index byte is the input or output number to adjust.
Modifier Bits:
==================
0x01: [1 = Input] [0 = Output]
0x02: [1 = Adjust Left] [0 = Don’t Adjust Left]
0x04: [1 = Adjust Right] [0 = Don’t Adjust Right]
0x08: [1 = Increment Gain] [0 = Decrement Gain]
10.4.10 Request Crosspoint Status
Format: [0x04]
The request crosspoint status message is a single byte command, which forces
the frame to immediately broadcast a crosspoint status message.
