3.5. Signal Strength Test to find the ideal Position:
Trouble free operation of the TED-system depends on spending time to properly install the TX and
RX.
Attention: You can only test the signal strength in the impulse transmission mode.
How do you start the signal strength test:
- Turn the TED-TX with device-switch (11) on.
- Press the device-key (10) of the TED-TX .
- Fasten the TED-TX in a good position (see page 11).
- Turn the TED-RX with device-switch (11) on.
- The loudspeaker of the TED-RX has now a sound and the LED blinks.
> As higher the sound, as higher (better) the signal strength.
> If the LED (3) blinks green:
high signal strength from the TED-TX.
> If the LED (3) blinks orange: low signal strength from the TED-TX.
> If the LED (3) blinks red: very low or no signal strength from the TED-TX.
> If you hear voices in the speaker it means, that this frequency is being used for talking. This
might cause trouble, you might lose data or impulses.
- The signal strength test ends automatically through a signal of the TED-TX after 1 minute (or
when you press device key (10) of the TED-TX).
Always try moving the TED-RX first. If you cannot find a proper signal strength, then try moving the
TED-TX. If it still fails then you have to reduce the distance or modify your application. Remember
that you can connect the TED-RX to any existing wiring.
You can only judge the signal strength at the TED-RX!
Attention - please notice if you have a short distance between TED-TX and TED-RX:
In order to work without troubles make sure that the distance between TED-TX and TED-RX is more
than 5 Meters. Otherwise it could overmodulate the receiver. For the TED-TX400 you should have a
minimum distance of 10 m.
