3.9 SINGLE LINE LEVEL INPUT SERIAL VOLUME CONTROLLER
This setup utilises a Redback® A 6512 Serial Volume Controller which has been designed to alter the volume of any low level
signal source feeding any amplifier or mixer remotely, via RS 232 or RS 485, or via the Redback® A 2280B remote volume
wallplate.
The Redback® A 6512 will interface directly to the Redback® A 6530 or A 6540 series wallplate or any other third party
control system which utilises RS232 or RS485 serial codes.
The figure below illustrates a typical connection diagram when using the Redback® A 6530 or A 6540 series wallplate or a
third party controller to control the Redback® A 6512 Serial Volume Controller.
The Redback® A 6530 or A 6540 series wallplate connects via a Cat5e/6 lead into the "To A 6500" RJ45 connection port of
the Redback® A 6512. 24V DC power is supplied to the Redback® A 6512 via a 24V DC plugpack or other 24V DC source
(minimum24V DC 1A).
Serial control of the volume circuit is provided by the A 6530 or A 6540 series wallplate which is programmed with the serial
codes using the PC software supplied with the wallplate.
The third party controller sends RS232 or RS485 codes directly to the corresponding RS232 or RS485 input connector of the
Redback® A 6512.
The output volume of the Redback® A 6512 is set by the serial codes sent to the unit.
