Expansion Module Cabling

Any expansion module used with the JNIOR Controller needs a way to connect to it. On each JNIOR is a sensor port that allows a cable to connect from the expansion module to the JNIOR. These are 6 6-pin modular Flat cables and they use RJ-12 connectors. These cables are supplied with the purchase of an expansion module. The length of the cable that comes with each expansion module varies depending on what expansion module is purchased. 

These cables can be made by anyone. All that is needed is a 6-pin modular Flat cable, two RJ-12 connectors, and a crimp tool. We have tested a cable length of 100 feet with one module, but the number of modules impacts the maximum length of the cable before failure. If the cable is too long, either the expansion module will lose power, or it will no longer receive data from the JNIOR to operate correctly. Testing and validation of the cable is up to the customer and INTEG provides no guarantees for the functionality of the modules when custom cables are used. If you are interested in making your own, here are some links to these items:

Materials needed

6 Pin Modular Flat Cable – Cut to desired length

RJ-12 Connectors

Rj-12 Crimp Tool

Strip the end

The end of the cable needs to be stripped.  This will expose the 6 individual wires.  The crimp tool has a stop, indicated by the arrow, that will ensure the correct length will be removed.

Insert the cable into the modular connector

Our rule of thumb is “white on the right with the tab down.  It doesn’t matter as long as both ends are done the same way.  Make sure to push the cable in all the way.  The second picture below shows the white wire going past the copper injection pins.

Crimp the connector onto the wire

Insert the modular connecter into the crimp tool and clamp down with moderate pressure.  Too light and the pins won’t puncture the insulation on the wires and touch the conductor.  Too hard and the connector can be broken.
