Abridged command set

The commands listed in the table below are some of those most commonly required when controlling a 46-120 from an
AV control system. For all other commands, data requests and responses, please refer to the CDI-46’s full RS-232 protocol

document.

GENERAL FORMAT

FUNCTION

COMMAND (ASCII)

Examples

1.

Input Selection

The values of x and y in the general format are the Line Input No. (1 to 6) and the Zone No. (1 to 4) respectively.

EXAMPLE

COMMAND (ASCII)

COMMAND (HEX)

Select Input 3 in Zone 2

3C 5A 32 2E 4D 55 2C 53 33 2F 3E

Zone Levels
Levels can either be set to an absolute value (in dBs), or increased/decreased by a specified number of dBs. Either may be
defined in steps of 1 dB.
For absolute levels, the number of dBs corresponds to attenuation rather than gain, thus 0 dB is maximum level and at -90
dB the zone is muted. The values of y in the general format is the Zone No. (1 to 4) and m is the attenuation level in one-dB
steps (0 to 90) respectively.
To alter the Zone level by a specified amount, the additional ASCII characters ‘U’ (up) or ‘D’ (down) are added to the string.
The values of y, p and q in the general format are the Zone No. (1 to 4), the level increase in one-dB steps (0 to 90), or the
level decrease in one-dB steps (0 to 90) respectively. A command to increment the level by a number of dBs greater than
the current attenuation will set the level to maximum. Similarly, a command that would decrement the level below 90 dB
attenuation will mute the Zone output.
