S1/S2 Switches

Note: The switches as shown in the diagram above are located behind a cover plate that can be

removed when you need to change the switch settings.

S1: Down puts the MultiModem in reset state.

Up runs the MultiModem properly.

Toggle the S1 switch down and back up to reset the MultiModem.

S2: Up keeps the GPS data signals separate from the wireless modem.

Down allows GPS data from Port 1 to flow to the wireless modem’s data in signal.

Configuring the Wireless Modem Side of the

MultiModem

1. Hardware Setup

1. Using an RS-232 cable, connect a workstation to the GSM/CDMA connector on the MultiModem.

2. Attach both antennas. The GPS antenna is a 50 ohm SMA antenna. The GSM/CDMA antenna is a

standard SMA antenna.

3. Switches S1 and S2 should be in the default positions – both up.

4. Plug one end of the power cord into the MultiModem and the other end into a live power outlet. The

PWR LED lights up.

Warning: Do not connect your wireless modem directly to a vehicle’s battery

for your power source. Doing so may cause power spikes. If you wish to use

the battery as a power source, add a filtering device to the DC input.
