Redback A 6514 User manual

Redback® A 6514 Two Input Serial Volume Controller
Operating Manual
OVERVIEW
This compact module has been designed to alter the volume of any low level signal source feeding any amplier or mixer
remotely, via RS 232 or RS 485. The unit includes two RCA inputs which are selectable by serial control and remote volume
which is also serial controlled.
The Redback®A 6514 will interface directly to the Redback®A 6500 wallplate or any other third party control system which
utlises RS232 or RS485 serial codes.
Fig 1 shows the layout of the front of the A 6514.
Fig 1.
1 24V DC input
Connects to a 24V DC Plugpack with a 2.1mm Jack (Please observe the polarity, centre positive).
2 24V DC Input
Connects to a 24V DC source via a euro block (Please observe the polarity).
3 RJ45 interface
This RJ45 port is for connection to other Redback®compatible devices.
4 RS485 Serial Input
This input takes an RS485 input signal. This can be connected to the RS485 serial output of the Redback® A 6505
or to a third party system. Follow standard RS485 wiring when connecting these terminals.
4 RS232 Serial Input
This input takes an RS232 input signal. This can be connected to the RS232 serial output of the Redback® A 6505
or to a third party system. Follow standard RS232 wiring when connecting these terminals.
6 RJ45 interface
This RJ45 port is for connection to the Redback® A 6500 wall plate.
7 DIP Switches
1 ON: Accept serial codes through RS485 input.

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 amplier.
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.

Figure 3 illustrates an example where the Redback® A 6514 need to be controlled but also other devices require control
from the Redback®A 6500 wallplate. In this example the Redback® A 6500 is connected to the Redback®A 6505 via
the Cat5e/6 cable which then passes through serial codes to the Redback®A 6514 via the RS485-1 terminals or RS232-1
terminals.
The Redback® A 6505 can then control relays, the IR repeater and send serial codes out the second serial port to other
equipment.

Redback® A 6514 Two Input Serial Volume Controller
SERIAL CODES
The Redback®A 6514 Serial Volume Controller is controlled by sending serial codes sent in the following format.
The serial data sent has to transmitted at 9600 baud, with the stop bit set to 1, data bits to 8 , parity to none and the
format must be ASCII.
Note: If the Redback® A 6500 wallplate is being used to send the serial codes, set the delay to 100ms.
Function:
Setting Output Level
The output level can be set to a given level between 0 (Off) and 79 (maximum).
To set these levels simpy send the code VOLUME? where ? is the number betwen 0 and 79.
The output level can also be increased or decreased by sending the following codes.
Increase Level = VOLUMEUX (where U stands for UP).
The X is the value to increase the volume. e.g VOLUMEU5 would increase the volume 5 steps.
Decrease Level = VOLUMEDX (where D stands for DOWN).
The X is the value to decrease the volume. e.g VOLUMED10 would decrease the volume 10 steps.
Selecting Input
Either Input 1 or Input 2 can be selected by sending the following serial codes.
To select Input1, send the code VOLUME, capital i and the number 1, eg. VOLUMEI1.
To select Input2, send the code VOLUME, capital i and the number 2, eg. VOLUMEI2.
If power to the A6514 is removed, the unit will remember its last Level setting, and which input was selected when power
is restored.
