Chapter 1 – Introduction and Product Description Chapter 1 – Introduction and Product Description This User Guide describes the MultiModem Wireless EDGE, GPRS, and CDMA modems with GPS functionality. Your product choice depends on the technology (cellular network) available to you.
Chapter 1 – Introduction and Product Description Safety Warnings General Safety The modem is designed and intended to be used in either fixed or mobile applications. In the “Fixed” application, the device is physically secured at one location and not easily moved to another location. In the “Mobile” application, the device may be regularly moved to different locations.
Chapter 1 – Introduction and Product Description Safety Recommendations for Rack Installations • • • • • • • • Ensure proper installation in a closed or multi-unit enclosure by following the recommended installation as defined by the enclosure manufacturer. If installing the wireless modem in a closed or multi-unit enclosure, ensure adequate airflow so that the maximum recommended ambient temperature is not exceeded.

Chapter 1 – Introduction and Product Description The Front Panel The MultiModem wireless EDGE modem with GPS functionality has 8 LEDs, 5 of which are modem LEDs, and a SIM card. The MultiModem wireless GPRS modem with GPS functionality has the same LEDs and SIM card as the EDGE modem. The MultiModem wireless CDMA modem with GPS functionality has the same LEDs as the EDGE and GPRS modem, but it does not, however, have a SIM card. LEDs PWR POWER. GPS GPS. Blinks to show GPS is active. IP IP FUNCTION.
Chapter 2 – Setup and Configuration Chapter 2 – Setup and Configuration Back Panel of the MultiModem with GPS The back panel view is included to help you understand the MultiModem setup. MultiModem with GPS Interface Back Panel 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.
Chapter 2 – Setup and Configuration 2. SIM Card for GPRS or EDGE The wireless modem requires the power supply connection to begin operation. It also requires a SIM card (Subscriber Identity Module) to operate on a GPRS or EDGE network. To install the SIM card: 1. Use a small screwdriver to remove the screw closest to the outside edge of the modem. Then swing the loosened SIM slot cover up and over to the left. 2. Insert the SIM card into the SIM card slot.
Chapter 2 – Setup and Configuration 5. Login Using TTY • Use TTY to configure your IP module for the first time. Configure the host serial port using the defaults listed below: Baud: 115.2K Data: 8 Parity: N Stop: 1 Flow-Control: None • Press the Enter key three times to get to the Login prompt. • At the Login prompt, type admin. • At the Password prompt, type admin. Important: User name and password are case sensitive. They must be typed in lowercase letters.
Chapter 2 – Setup and Configuration Configuring the GPS Side of the MultiModem 1. Port Configuration The GPS receiver module has two I/O ports. The table below provides the default protocols and port configurations for the receiver, as delivered from the factory. TSIP IN/OUT is the default protocol on Port 1 and RTCM-IN and NMEA-OUT is the default protocol on Port 2.
Chapter 2 – Setup and Configuration 2. Hardware Setup 1. Using an RS-232 cable, connect a workstation to the GPS connector on the MultiModem. 2. Attach both antennas (included in your ship kit). The GPS antenna is a 50 ohm SMA antenna. The GSM/ CDMA antenna is a standard SMA antenna. 3. Plug one end of the power cord into the device 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.
Chapter 3 – Setup/Configuration Examples Chapter 3 – Setup/Configuration Examples Application Example 1 In this example, the GPS side of the MultiModem is monitoring GPS locations and the wireless modem side of the MultiModem is waiting for incoming data. A portable workstation, such as a laptop or handheld PC, is connected to this wireless modem to both serial ports – the GSM/CDMA port and the GPS port. 1. Using an RS-232 cable, connect the GPS connector jack to portable PC’s serial port. 2.
Chapter 3 – Setup/Configuration Examples Application Example 2 This example shows the MultiModem GRPS Wireless Modem with GPS mounted in a truck that can be tracked by a GPS satellite. This configuration shows a MultiModem located in a vehicle and not connected to a portable PC. The MultiModem in this example simply reads the GPS data as it is sent from GPS satellite, and then it broadcasts the data to your central tracking system by way of your CDMA, GPRS, or EDGE network provider connection.
Chapter 4 – Antennas and Cables Chapter 4 – Antennas and Cables The Antenna The antenna sub-system and integration in the application is a major issue: Choice of antenna (type, length, performances, thermal resistance, etc.) These elements could affect GSM performances such as sensitivity and emitted power. EDGE, GSM, and CDMA Antenna The integrated modem antenna connector is a SMA connector.
