1.0 OVERVIEW
1.1 INTRODUCTION
This universal touchscreen wallplate is the perfect control system for commercial and domestic automation. Its stylish low
prole design lends itself to installation in new modern homes, classrooms, lecture theatres or corporate boardrooms. The
LCD panel can be congured from 1 to 12 buttons, which can be individually labelled. Conguration is performed using
the supplied software, which is then transferred to the plate via SD card. A library of button icons is included. Icons can be
customised by the user if required. Each button can be programmed for either serial with hex code commands, IR, or relay
control. For IR applications the plate can learn and capture IR strings from any remote control. User generated macros can
be created consisting of multiple commands in a single button press. This is ideal for performing multiple tasks at once ie:
turn on projector, turn on amplier, turn off lights, drop down projector screen etc.
For IR applications the plate can learn and capture IR strings from almost any remote control.
User generated macros can be created consisting of multiple commands in a single button press. This is ideal for perform-
ing multiple tasks at once ie: turn on projector, turn on amplifier, turn off lights, drop down projector screen etc. Wall
plate ts into a standard electrical wallbox for ease of installation.

Switch 2: ON - Buzzer active, OFF - Buzzer disabled.
5 P1 Jumper Terminal
The A 6505A Serial Hub has three relay outputs and a PIR Trigger Input. The third relay output and the PIR
trigger use the same connection from the microcontroller inside the unit. This P1 jumper is used to congure the
A 6505A for use with the PIR trigger or with the relay 3 output. Using the shunt header supplied, t the shunt on
pins 1 and 2 for relay 3 operation. For PIR operation t the shunt to pins 2 and 3.
6 RJ45 Connector
This is used for the connection between the wallplate and Serial Hub or Distribution boxes. Connection is made
using Cat5/6 cable to a maximum distance of 50m.
7 RJ45 Connector
This is used when connecting two plates together for Tandem operation. (Note: Both plates need to be connected
to this socket).
2.2 WALL PLATE MOUNTING BRACKET
Figures 2.2a and 2.2b show the mounting brackets to suit the two different size wall plates.
The holes shown have the correct spacing for Australian standard wall boxes.
To mount the wall plate to a wall box use the supplied screws. If not using a wall box then mount the bracket using screws
suitable for the mounting surface (not supplied).
To t the wall plate to the mounting bracket, rst insert the hooks at the top of the bracket into the mouting slots on the
back of the wall plate. Then push the bottom of the wall plate against the wall making sure the bottom of the bracket
ts into the cutout on the rear of the wall plate. Using the supplied countersunk M2.5mm bolt/s, secure the plate to the
bracket (Note: the bolt/s will pull the plate upwards so that the hooks at the top of the bracket t tightly into the wall
plate).

3.8 SERIAL CONTROLLED 100V LINE ATTENUATOR
This setup utilises a Redback®A 6507 seven step 100V 50 Watt line speaker attenuator/volume control which can be re-
motely adjusted via RS485 serial control. A 24V DC override relay is included for emergency paging applications, ensuring
the volume is switched to maximum regardless of the volume setting.
The unit is suitable for all 100V line ampliers and connects between the amplier output and the speakers to be controlled.
The Redback®A 6507 will interface directly to the Redback®A 6530 or A 6540 series wallplate or any other third party
control system which utlises RS485 serial codes. The attenuator circuit includes a 22uF BP capacitor for line monitoring ap-
plications.
The gure below illustrates a typical connection diagram when using the Redback® A 6530 or A 6540 series wallplate
wallplate to control the
Redback®A 6507 Attenuator. The Redback® A 6530 or A 6540 series wallplate connects via a Cat5e/6 lead into the “To A
6500” RJ45 connection port. 24V DC power is supplied to the Redback® A 6507 via a 24V DC plugpack or other 24V DC
source (minimum24V DC 1A).
Serial control of the attenuator 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 audio into the attenuator is provided by an amplifer with a 100V line output. The attenuated signal is then output out
of the attenuator into the speaker load up to a maximum of 50 watts of load.
Emergency or paging override of the audio can be achieved by applying 24V DC to the Override Relay terminals. Once
activated the output volume will switch to maximum regardless of the volume setting.
