3 Connecting the LMA-3
The LMA-3 looks like this:
3.1 Connecting the LMA-3 to an LM-1
Plug the supplied Mini-DIN8 to Mini-DIN8 cable in the LM-1 port of the LMA-3. Plug the other
end of the cable into the AUX-IN port of the LM-1.
The LMA-3 is now operable and is powered by the LM-1.
NOTE:
The 5V power supply for external sensors should not be used when the LMA-3 is solely
powered by the LM-1.
3.2 Using the LMA-3 as part of a Log-Chain
If the LMA-3 is the first device in the Log-Chain, it’s Serial IN port MUST be plugged by the
supplied Terminator plug. The Terminator is a 2.5mm Stereo connector with no cable attached.
3.3 Connecting external sensor signals
For each external connection you can connect the external sensor’s output to the CHx+
connection. Connect the CHx- connection to the ground of the sensor. Make sure the sensor
output signal does not exceed 5V. The LMA-3 is protected if sensor signals exceed that (up to
40V for most inputs), but it cannot measure beyond a 5V signal.
