HANNEL EVELS AND
Get Channel Level - Causes the AS8 to send to the host channel levels, either singly or all eight. Range is from 0- 255,
where 0 corresponds to -65.33dBu, and 255 to +20dBu.
Host sends command - 3
Host sends 1 byte: a value 0-7 causes the AS8 to output the level of a single channel, 1-8. A value of 8 or greater
outputs the level from all eight channels as eight consecutive data bytes.
Host receives 1 or 8 bytes: for the channel level(s).
Get Channel Attenuation - Causes the AS8 to send to the host channel attenuation, either singly or all eight. Range is
from 0-255, with each bit scaled to .33dB. The output channel attenuation number is the sum of the remote
channel and remote main attenuation values, the attenuation from the automatic algorithm, and the attenuation
from the compressor/leveller system (if used).
Host sends command - 4
Host sends 1 byte: a value 0-7 causes the AS8 to output the level of a single channel, 1-8. A value of 8 or greater
outputs the level from all eight channels as eight consecutive data bytes.
Host receives 1 or 8 bytes: for the channel attenuation(s).

EMOTE TTENUATION
Set Remote Level Read Flag - Allows the host to set the value of the Remote Level Read Flag. If the flag is 0, the AS8
reads the 15 pin remote level port to determine the remote channel attenuation value. If the flag is set to 1, remote
channel and main attenuation values used are those input from the serial port. The new flag value is stored in
EEPROM.
Host sends command - 7
Host sends data byte: 0 or 1, where 0 = values from DB-15 port, 1 = values from RS-232
Get Remote Channel Attenuation - Causes the AS8 to send to the host remote channel attenuation, either singly or all
eight. Range is from 0-255, with each bit scaled to .33dB. Note that this number represents the sum of the
individual plus the main channel remote attenuation values. If the Remote Level Read Flag (see command 7 below)
is 0, the values returned will be those from the DB-15 remote level port. If the Remote Level Read Flag is 1, the
values returned will be those currently in memory.
Host sends command - 5
Host sends 1 byte: a value 0-7 causes the AS8 to output the remote attenuation value of a single channel, 1-8. A
value of 8 or greater outputs the level from all eight channels as eight consecutive data bytes.
Host receives 1 or 8 bytes: for the remote channel attenuation(s).
Set Remote Attenuation Values - Allows the host to set the remote attenuation levels of the AS8. Valid input data is
0-31. 0-30 gives 0dB to 30dB attenuation. 31 is off. Note that the Remote Level Read flag must be set to 1 for this
command to be valid (see "Set Remote Level Read Flag" command below).
Host sends command - 6
Host sends channel byte: 0-7 to signify which channel 1-8 to change.
Host sends data byte: 0-31 for attenuation value as outlined above.
Get Remote Main Attenuation - Causes the AS8 to send to the host remote main attenuation. Range is from 0-255, with
each bit scaled to .33dB.
Host sends command - 29 (10 hex)
Host receives 1 byte: 0-255 for the remote main attenuation level.
Set Remote Main Attenuation - Allows the host to set the remote main attenuation level of the AS8. Valid input data is
0-31 (0-1F hex). 0-30 gives 0dB to 30dB attenuation. 31 is off. Note that the Remote Level Read flag must be set
to 1 for this command to be valid (see "Set Remote Level Read Flag" command below).
Host sends command - 34 (22 hex)
Host sends data byte: 0-31 to program main attenuation value as outlined above.
