3. Command Specifications
3.1 Basic Command Specifications
A command type transmitted between the TXn/ACD1 and the Remote Controller is in the following format:
<Command name> <Option 1> <Option 2> … <Option n><Line feed
>
- LF (0 x 0A) will be needed at the end of a command as a line feed code.
- At least one space will be needed between a command name and an option or between options.
- A command must consist of only ASCII character strings. Other character strings cannot be used.
- Optional character strings for parameter values are shown in the following table.
-Inf -13801
-18dB -1800
-6.5dB -650
0dB 0
10dB 1000
2kHz 2000
400Hz 400
Pan L 63 -63
Pan Center 0
Pan R 63 +63
ON 1
OFF 0
REVERSE 1

Character strings such as "ON" or "HARD" are not returned as a parameter value.
- A fader parameter value will take the following character strings using a curve table method.
(See chapter 3.3.1 for details on curve table methods and the Appendix at the end for values in dB and the character strings.)
A table for a fader of which maximum is 0 d
B
A table for a fader of which maximum is 10 d

3.2 Command Notified to Remote Controller from the TXn and ACD1
3.2.1 Parameter Control Comman
d
1) PRM: Used to change a parameter other than a fader parameter, and a fader using a dB method.
2) VOL: Used to change a fader using a curve table method.
Comman

Optio
n
PRM [AMP ID] [Access ID] [Parameter value]
VOL [AMP ID] [Access ID] [Level value
]
The command names stand for "Parameter" and "Volume" respectively.
These commands will be sent from the TXn/ACD1 when a parameter registered in Remote Control Setup List of TXn/ACD1 Designer is changed.
- If sending from a TXn, [AMP ID] is always 0. If sending from an ACD1, [AMP ID] is the AMP ID (0 to 39) assigned to the amp to be controlled.
- [Access ID] is the 17 strings including "/" of the parameter to be controlled. (See separate parameter map.)
- [Parameter value] and [Level value] contain appropriate character-string values.
- A space will be needed between the command and the option, and between the options.
- No notification is made for changes to library-protected parameters.
E.g.) If the value of TXn parameter (Att chA, Access ID 0000/10/0000/0100 ) is changed to 0dB, the following string is sent from the TXn.
PRM 0 0000/10/0000/0100 0
If the value of Tn parameter connected to ACD1(Output Mute chA, Access ID 0000/02/0000/0000 ) is set to MUTE,
the following string is sent from the ACD1.
PRM 0 0000/10/0000/0100 0
If the value of a fader parameter (curve-table type, max 10dB) is changed to -20B, the following is sent from the TXn.
VOL 0 0104/00/0100/0000 423
