3 Power Supply
3.1 Supply voltage requirements
The DC power supply must be connected to the POWER input:
•
Input voltage range 5 - 36V DC
•
Nominal Voltage 12V DC
Application of the supply voltage does not switch the modem on. To do so an additional active-high
control signal, TO_IN, must be applied for > 0.2s.
Please see chapter 3.3 Switching on the modem for further important details about TO_IN and power
supply requirements, especially if TO_IN is applied in parallel to VCC.
VCC and GND are reverse-polarity and over-voltage protected. Please note: this does not apply for
the GND on the antenna connector if this coax GND/shield is connected to your applications ground-
plane.
NOTE: In case that power supply equipment is to be ordered, its conformity needs to be verified with
the mains supply voltage, frequency, connector type and other national requirements (e.g.
certifications) in the countries of its use.
3.1.1 Power Connector
An RJ11 6-way connector, as shown and described below, serves as a means of supplying and
controlling DC power to the modem.
