Two Input Serial Volume Controller
CONNECTIONS
Figure 2 illustrates a typical connection diagram when using the Redback
®
A 6500 wallplate or a third party controller to
control the Redback
®
A 6514 Serial Volume Controller.
The Redback
®
A 6500 connects via a Cat5e/6 lead into the “To A 6500” RJ45 connection port of the Redback
®
A 6514.
24V DC power is supplied to the Redback
®
A 6514 via a 24V DC plugpack or other 24V DC source (minimum24V DC 1A).
Serial control of the volume circuit is provided by the A 6500 wallplate which is programmed with the serial codes using the
PC software supplied with the Redback
®
A 6500. (Refer to the Serial Codes section for details).
The third party controller sends RS232 or RS485 codes directly to the corresponding RS232 or RS485 input connector of the
Redback
®
A 6514. The code must be sent in the correct format as outlined in the Serial Codes section.
In this example the audio into the Redback
®
A 6514 volume controller is provided by two DVD players with standard RCA
line level outputs. The attenuated signal is then output out of the Redback® A 6514 volume controller into the line level
input of an amplifier.
Either Input 1 or Input 2 can be selected by serial control and the output volume of the Redback® A 6514 can also be set
by the serial codes sent to the unit as outlined in the Serial Codes section.
