Models With Rj11 Connector - MTX -3G-JAVA-IoT User Manual

4.1.3 Models with RJ11 connector

An RJ11 6-way connector, as shown and described below, serves as a means of supplying DC power to
the modem.
The power supply voltage (VCC) required by the modem is in the range of 7 to 50VDC. We recommend
a 12V DC power supply. The power supply has to be a single voltage source capable of providing a
current peak during an active transmission. The uplink burst causes strong ripples (drop) on the power
lines.
MTX-IoT devices are shipped to automatically switch on only with supply between PIN 1 and PIN 6.
