Transmit ESC
Audio #1 Volume
Transmit ESC
Audio #2 Volume interface card is installed, and the transmit mode
parameter is set to IDR Mode. If an IDR OR IBS interface
card is not installed, set to zero. If an IDR OR IBS
interface card is installed, but the transmit mode
parameter is not set to IDR mode, these bytes can be set
to any valid values, but will be ignored.
-20 to +10, signed binary value in dB
Note: The following two bytes apply only if an IDR OR IBS
interface card is installed, and the transmit mode
parameter is set to IDR Mode. If an IDR OR IBS interface
card is not installed, set to zero. If an IDR OR IBS
interface card is installed, but the transmit mode
parameter is not set to IDR mode, these bytes can be set
to any valid values, but will be ignored.
-20 to +10, signed binary value in dB
