1. Power Supply Connector
Depending on the specific modem you are using, you will dispose of one of the connectors described in
the sections below. Please read them carefully.
1.1 Models with Power Relay 220V/6A (5-way plug-in 5.00mm pitch terminal
block)
A 5-way plug-in terminal block connector shared with a 220VAC/6A relay, as shown and described below,
supplies the D.C. power to the modem.
The supply voltage, VCC, required by the modem is in the range of 7 to 50VDC. We recommend a 12VDC
power supply. The power supply has to be a single voltage source capable of providing a peak during an
active transmission. The uplink burst causes strong ripples (drop) on the power lines.
By default, the MTX-Java-IoT will automatically switch on when power supply is applied between PIN 2
and PIN 1.
