Getting Started Getting Started with your Wireless MultiModem Mechanical Mounting To mount the Wireless MultiModem, do the following: 1. Obtain mounting screws (two are needed) that are appropriate for the surface on which you will mount the MultiModem. The mounting screw on the connector end of the unit must have a screw-head no thicker than 2 mm. The allowable thickness is limited because the screw must fit beneath the RS232 cable.
Getting Started For example, one might use two 6-32 selftapping screws 5/8” in length to mount the unit in a truck to the wall of the cab behind the passenger’s seat. 2. Typically, the unit is mounted against a flat surface into which holes can be drilled. The mounting holes (center-to-center) must be separated by 125mm or 4 -15/16 inches. Screw Separation = 125 mm 15 or 4 16 inches Drill the mounting holes at the desired mounting location (if applicable).
Getting Started 3. Slide the mounting bridles into the corresponding slots on the back side of the MultiModem chassis. 4. Attach the MultiModem with two screws to the mounting surface at the desired location on the equipment.
Getting Started Electrical Installation & Configuration The wireless MultiModem requires the power supply connection to begin operation. It also requires a SIM card (Subscriber Identity Module) to operate on a GSM network. To install the modem, do the following: 1. Using your fingernail or a small wedging tool (e.g., a small screwdriver), pry off the SIM cover.
Getting Started 2. Insert the SIM card into the holder.
Getting Started 3. Verify that the SIM card fits into the holder properly and then replace the cover.
Getting Started 4. Connect a suitable antenna to the SMA connector (see specifications on page 8).
Getting Started 5. Connect both sides of the serial and control cable (15-pin Sub D connector on the modem side).
Getting Started 6. Plug the power supply cable into the wireless Multimodem. Power Cord In-Line Fuse Power Connector To Power Source 7. Connect the power supply cable into the power supply, with a correct GND connection. Connect red wire to + (positive) and black wire to – (negative). Note: For automotive application: according to the type of application, you can use permanent “+” or key-switched “+”.
Getting Started Connect the power supply to its source (for example, in a mobile situation, to the vehicle’s DC fuse/terminal block). 8. Activate the power supply. Mobile Phonetools For initial configuration of your wireless device, Multi-Tech offers a Windowsâ based mobile Phone Tools application. To load mobile Phone Tools, click on the mobile Phone Tools icon on your system CD and follow the on screen prompts.
Getting Started Verifying signal strength The Wireless MultiModem establishes a call if the signal is sufficiently strong. To verify the signal strength, do the following: 1. Using the Hyperterminal program at the computer to which the Wireless MultiModem is connected, type the AT command AT+CSQ. A value for the received signal strength will be returned. 2.
Getting Started Verifying network registration In this procedure, you will verify that the Wireless MultiModem has been registered on the wireless network. To do so, you will use the common communications program Hyperterminal. 1. Using the Hyperterminal program at the computer to which the Wireless MultiModem is connected, type the AT command AT+CREG?. A value for the modem’s network registration status will be returned. 2.
