Models With Rj11 Connector - MTX -4G-JAVA-IoT Hardware User's Manual

1.2 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-Java-IoT devices are shipped to automatically switch on only with supply between PIN 1 and PIN 6.
