T470 Users and installation manual, Part A, V103
Aug 21, 2019
Introduction
The JED T470 unit is a wall-mounted controller which communicates
with a projector or flat panel via RS232 or IR.
The T470 has an RS232 interface wired to a 5-way Phoenix connector
and a CAT5. Tx and Rx lines only are provided, no handshake lines
are used.
If the unit is ordered with the –R2 option (two relay
outputs), the RS232 connection can only be made via the CAT5
cable.
It also has a pin called “Res” which can be used as a PIR (Passive
Infra-Red) input, an IR output or a voltage output to drive an external
solid state (directly) or a mechanical relay (via an external FET
device).
Safety Instructions
•
Caution: There are no operator serviceable parts inside the controller.
•
Warning: Disconnect the power and unplug the power supply from the wall before installation.
Power supply
Both connectors also have a ground and a 12 volt input for power supply purposes. This can be unregulated 9 to 15
volts DC, although JED normally supplies the T470 with a small regulated plug pack when sold into the Australian or
New Zealand market. Current consumption is approximately 50mA.
(Connections and wiring to the T470 are covered in the later part of this manual, page 6)
Setting up the T470
To set up the T470 it is necessary to connect the T470 RS232 port to a PC, either directly to a hardware RS-232 serial
port or to a USB -> RS232 connection to the PC.
While more details of wiring the T470 follow, basically the following 3-wire connections are needed. If the T470 does
NOT have the relay option installed, this can be to the Phoenix screw terminals or via a short CAT5 cable.

Connect a 12-volt power supply to the T470. Use a multimeter to verify polarity … the white stripe on the power
adaptor cable sometimes indicates –ve, sove. A hint: strip 5mm of plastic from the wire and fold back once
over the plastic. Open the screw fully, then slide wire AND plastic into the Phoenix screw terminal before tightening the
screw on both. This makes for a stronger termination. It will start up with the red LED above the OFF key lit.
