All Other Models (5-Way Plug-In 5.00Mm Pitch Terminal Block) - MTX -3G-JAVA-IoT User Manual

4.1.4 All other models (5-way plug-in 5.00mm pitch terminal block)

A 5 way plug-in terminal block connector shared with RS485 bus, as shown and described below,
supplies 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-IoT will automatically switch on when power supply is applied between PIN 2 and
PIN 1.
