5.2.2 CAI Address Settings
The CAI address selection procedure will not affect the operation of the VORTEX
but whilst this procedure is active, the volume cannot be adjusted by using the
pots.
Briefl y press the Enter-Switch
. This push button switch can be accessed
through the 3 mm hole in the front panel between the On/Off switch and the
LEDs. Only operate this switch with an insulated object.
The current address will then be displayed by the On LEDs.
Flashing of On LED channel A indicates the tens of the address
Flashing of On LED channel B indicates the units of the address
These sequences are repeated for 30 seconds (timeout). Then the On LEDs
return to their normal function.
To change CAI address, turn the appropriate volume potentiometer to the required
address (volume pot channel A => TENS, volume pot channel B => UNITS).
To see the address you can use the scale markings of the potentiometers.
You will fi nd the digits 0,1,...,9 on the 10 scale spacings.
The current selected address will be immediately displayed but not auto-
matically stored or activated! After each turn of pot you have another 30
seconds to Timeout. You can exit this procedure without saving the new address
by briefl y pressing the Enter-Switch
or waiting for Timeout (as described
above).
To store and activate the new address you have to press the Enter-Switch for
3 seconds. This new address is stored in an EEPROM, which holds the information
even if the amp is subsequently disconnected from the mains.
Be sure to set the CAI-Master-PC to this new address. If not, the communication
will be interrupted.
Example of LED sequences for different address settings:
Address On LED Channel A ⇒TENS On LED Channel B ⇒UNITS
01 (factory settings) 0* fl ash 1* fl ash then short pause
25 2* fl ashes then short pause 5* fl ashes then short pause
NOTE: Ensure you return both pots to their original position after address
selection is complete, otherwise the amplifi er will change its volume level
to the new pot positions!
