Connect a suitable antenna to the SMA connector (see antenna specifications in Chapter 1).
If you are connecting to a serial interface, connect the DE9 connector (9-pin) of the RS232 cable to the RS232
connector on the modem and connect the other end to serial port on your PC.
Connect the GPIO cable to the I/O connector on the modem and the other end to the external device that the modem
is monitoring.
Depending on the power source, connect either the power supply module with the appropriate blade or the optional
DC power cable. If you are using the power supply module, remove the protective shipping cover. Attach the
appropriate interchangeable blade piece to the power supply module.
If you are connecting to an USB interface, connect an USB cable to the USB connector on the back of the unit and the
other end to the USB port on your PC.
Screw-on the power lead from the power supply module to the power connection on the modem. Now, plug the
power supply into your power source.
For Optional Direct DC Power
Warning:
Note:
•
•
•
Screw-on the DC power cable to the power connector on the modem.
Then attach the two wires at the other end of the DC power cable to a DC fuse/terminal block on a vehicle in
which you are mounting the MultiModem.
Connect red wire to the "+" (positive) terminal and black wire to the "–" (negative) terminal. Be sure the GND
connection is correct.
For automotive application: according to the type of application, you can use permanent “+” or key-switched
“+” source. Connect the power supply to its source (for example, in a mobile situation, to the vehicle’s DC
fuse/terminal block).
Over-voltage protection is provided on the device. To ensure complete protection, you may want to add
additional filtering to the DC input.
