 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 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, 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 or CA200z user manual for further details)
 The numerical values are always integer numbers without
comma or dot symbols
 <Input Name> 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
o LINE2_AND_MICRO
