Installation and Operation Guide

Page 1-10 MTX-15 Installation & Operation Guide
*The maximum number of terminals is dependent upon the distance and
the quality of cabling used. It is recommended that Belden Low Voltage
Computer Cable, P/N 9841 or equivalent be used to connect the junction
boxes for this application.
Warning! Please note that terminal #3 (used for the RS-485 cable
Shield) is disconnected from the internal RJ-11 receptacle
of the junction box. This is deliberate; the shield connection
is NOT fed through to the MTX-15 Terminal.
