Electrical Description

 

The modem uses the following standard connectors: 
 

 

RJ11 6-way (power connector) 

 

Mini USB (USB 2.0) 

 

SIM card reader 

 

FME male coaxial jack (antenna connector) 

 

Sub-D female socket, 9 pin (RS232 serial port)

 

4.1

 

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. It is necessary 
to connect an external power supply, since the available power on the USB 
port is not sufficient to run the modem. 
 
The supply voltage, VCC, required by the modem is 5V - 32V 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 > 1 second. 
 
Please see chapter “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. 
 

Note:

 

This does not apply for the GND on the antenna connector if 
this coax GND / shield are connected to your applications 
ground-plane.
