3c: Radio mode Key A
A number of keys form a group with “Radio” functions, i.e. press Key A
and the first relay operates and LED lights. Press Key B and the second
relay in the group operates and the second LED lights. Any On relays
release and On LEDs turn off when any other key is pressed. One, two,
three of four Radio keys can be defined. (In a three-relay T470, the
fourth key just turns the other three Off.)
3d: Radio mode Key B
3e: Radio mode Key C
3f: Radio mode Key D
40: Source Key 1 Actioned
Relay operates when defined Source Key is pressed, and stays on
while display device is on that channel. Selecting another source key
with a relay linked to it releases the previous one.
This context provides for relay-operated switchers whose channel is
selected with the T470 source buttons. If this is the mode of use, set all
display device sources to be the same, and set to display the output of
the switcher.

Hardware connections to T470
The T470 mounts into standard Aust/NZ power-point hardware. The metal bracket screws to the wall using any or all of
the oval screw holes. (It has slots making it compatible with “C” clamps allowing mounting on a plaster wall.)

Wiring options
There are a several ways to wire to a T470 unit depending on whether relay option is installed:
1.
Via a single CAT5 cable. This has simplicity, requiring just one pre-terminated 4-pair cable to connect 12v
power, RS232 and either an IR output or a PIR input;
2.
Via just the 5-way screw terminal connector. This allows a power pair from a plug pack and an RS232 cable
and an extra wire (for IR out or PIR in) to be connected via screw terminals Note: this option cannot be used if
relays are installed.
3.
Via a combination of these two. This is required where the T470 has relay option to drive a screen, audio or
projector power switching relay, etc.
With all options due care should be exercised when routing data cables to avoid interference from potentially noisy
electrical items such as fluorescent/LED lights, motors etc
.
