1.2 General Command Handling
Commands are sent as ASCII character string with spaces used to delimit fields within a
command. The entire command is terminated with a Carriage Return (0x0D). The device
acknowledges a command by returning the command data with the string “ACK” inserted
preceding the command data. If the device could not process a command, then the
command is “NACKed”. The string “NACK” is inserted preceding the data that was sent.
NACKs are returned for unknown commands, commands with invalid parameters, or for a
LOAD command for a preset that has not been previously SAVED.
1.3 Command Descriptions
1.3.1 Phantom Power
The Phantom Power command activates or deactivates the Phantom Power on a particular
input.
Set CH2 Phantom Power on:
PP 2 1<CR>
Response:
ACK PP 2 1<CR>
Set Phantom Power off on all channels:
PP 0 0<CR>
Response:
ACK PP 0 0<CR>
Invalid Phantom Power command (the State variable is not a 0 or 1):
PP 2 2<CR>
Response:
NACK PP 2 2<CR>
1.3.2 Identify/Find Unit
The Identify and Find Unit commands are both used to permit a given unit to be physically
identified. Both commands cause the Power LED to flash at an approximate rate of 330
milliseconds / on / off. The difference between the commands is that the Identify com-
mand has an ON / OFF parameter and remains in the selected state until a new Identify
command (or CDT100 reset event) is sent to change state. The Find Unit command flashes
the Power LED for 5 seconds, the Power LED function then resumes without sending any
additional commands. The Power LED will also flash when the Dante Controller “Identify
Device” function is used.
Set Identify on:
ID 1<CR>
Response:
ACK ID 1<CR>
Activate Find Unit:
FU<CR>
Response:
ACK FU<CR>
