Getting started

Thank you for purchasing a Logic Rail Technologies product! This board provides hardware-based control inputs for our
Light EFX-16 board. There are two pairs of connectors on this input board; each pair contains a 10-pin connector and a 16-
pin connector. The two pairs are split between inputs 1-8 (corresponding to Lights 1-8 on the Light EFX-16) and inputs 9-16
(corresponding to Lights 9-16 on the Light EFX-16). The input board obtains its power from the Light EFX-16 board and
communicates with it through the 6-pin header on the left-hand side of the board. When properly connected, and power
turned on, a green LED will illuminate on the input board.

For each pair you will use EITHER the 10-pin connector OR the 16-pin connector. You cannot and must not try to use both
connectors within a pair! The choice between which connector to use within each pair is up to you. You might select the 10-
pin connector if you have already invested in the 10-wire cables and mating connectors for any LCC products from RR-
Cirkits (https://www.rr-cirkits.com/).

10-pin connector

Please pay close attention to our pin definition shown below. Note that this connector is keyed so that you can only attach the
mating cable assembly one way. The drawings below show the pin and wire definitions as viewed with the board oriented in
the photo above!

The photo which follows shows the proper orientation of the 10-wire cable assemblies. Note: if you need to detach a cable
assembly from the input board make sure you grab the connector on the cable assembly from the short sides and gently rock
it from short side to short side.
