1.3 Functional Block Diagram
Figure 1: Functional Block Diagram for MLB-G420X
The MLB-G420X consists of a fully certified (CE /NCC approved) GSM/GPRS engine, SIM card holder and
power regulator.
The wireless terminal is supplied with power via the DC jack and terminal block. The remaining RJ45
connector is used for data communications.
The SMA female connector provides the air interface to an external 50 ohm antenna specified for the
correct frequency band.

1.4 Precautions
The MLB-G420X wireless terminal is designed for indoor use only. For outdoor use, it has to be integrated
into a weatherproof enclosure. Do not exceed the environmental and electrical limits as specified in the
user manual.

Note: The reset button is located on the top panel of MLB-G420X. You can reboot it to
factory default settings by pressing the RESET button with a pointed object such as an un
folded paper clip.
System reboot: Hold the RESET button down for 1 second and then release
Reset to factory default: Hold the reset button down for 30 seconds while the READY LED and
SIM LED go off until READY LED starts bliking green. Release the button to reset the
MLB-G420X.

Figure 7-2: Antenna Connectors for MLB-G4202
Note: For the model of MLB-G4202, it is strongly recommended to install both antennas to gain
the better quality of cellular signal. For a reminder, it is mandatory to install ANT1; if you only
install ANT2, there would be no cellular signal received to establish the traffic communication.
For optimum RF performance, the MLiS wireless terminal has to be connected to an external RF antenna
matched to 50ohms. Please use a SMA Male connection for the wireless terminal.
