 GET
 SET
 DATA
 ERROR
At the end of this document you’ll find a table including all the available messages and their
parameters for each model of CA‐NET compatible device.
The GET & SET messages can be sent from the client (control system) to the CA / DAM device. The
DATA & ERROR messages can just be sent from the CA / DAM device to the client.
The SET messages coming from a client device don’t have an automatic acknowledgement with a
DATA message sent from the CA / DAM device after it has processed the SET command. The client
must update the values itself, sending the needed GET message to ask for a parameter’s value
when it requires confirmation from the device. On the other hand, when a local control in the CA /
DAM unit occurs (for instance, using the front panel controls or an infrared remote control), the CA
/ DAM device will automatically send the associated
DATA command via its RS‐232 interface, to
keep synchronisation with the client device.
CA40, CA120 and CA200z NOTES:
 A couple of special parameters for the GET and SET commands would require a detailed
explanation:
1. AUTOLOAD_PRESET1 : its value (ON/OFF) defines whether preset number 1 must be
recalled or not each time the CA device is powered ON, defining this way the default
working mode at startup
2. PANEL_LOCKED : its value (ON/OFF) defines whether the front panel controls (the rotary
encoder in the case of the CA40/CA120, and the encoder and the function keys in the
case of the CA200z) is enabled (PANEL_LOCKED=OFF) or disabled (PANEL_LOCKED=ON)
for local management of the device. (see the CA40/120 or CA200z user manual for
further details)
 The numerical values are always integer numbers without
comma or dot symbols

are text strings (without blank spaces) that identify an audio input of a CA
device:
For the CA40, there are 5 possible Input Names:
o LINE1
o LINE2
o MICRO
o LINE1_AND_MICRO
