Connection and commissioning
5.1 - SIM CARD INSERTION
To have access to the SIM card compartment, it is necessary to remove the rubber cover
of the device and then to insert the SIM card with the circuit facing down and the beveled
corner must be to the upper left, as shown in the figure.
5.2 - EXTERNAL ANTENNA
The antenna supplied might fail to provide for an optimal reception of the RF signal in well-defined operating
conditions. For this reason,
CUBE PLUS is also arranged to operate with an external omnidirectional antenna.
The antenna includes a dipole, a wall fixing metal bracket and an extension cable.
IMPORTANT : the external antenna installation should be performed by qualified personnel only.
The external antenna should have the following properties:
- Frequency Range ( MHz) : 698
～
960/1710
～
2690
- VSWR. ≤ 2.0
- Gain peak ( dBi): ¼
- Input Impedance(
Ω
): 50
- Polarization: Vertical
- Connector Type: SMA-J
5.2.1 - Instructions for using the antenna
The antenna shall be arranged at least 2 m far from any electronic equipment that may be available in the
environment and at least 15 cm far from any obstacle. It shall be put into such a position that it can provide
for a good reception of the radio field.
If the local equipment should start showing any malfunction or disturbance when the equipment is in use,
move the antenna to another place.
Avoid using the monopole when the equipment is installed in a closed or particularly shielding environment.
Use the external antennas with a nominal impedance of 50

.
Never put your hands on the antenna when the device is in use. This may compromise the quality of the
connection and force
CUBE PLUS to require a higher transmission power.
Never use CUBE PLUS if the antenna is visually damaged. In this case, it shall be replaced without any delay.
6 - POWER SUPPLY
The interface can be supplied by direct current with a 12-24 Vdc nominal voltage.
Equipment is intended to be supplied by d.c. power supply having a transient voltage of 1500 Vpeak
