Chapter 2 – Installation Chapter 2: Installation 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. The allowable thickness of the other screw-head is not limited in this way.
Chapter 2 – Installation 3. Slide the mounting bridles into the corresponding slots on the backside of the MultiModem chassis. 4. Attach the MultiModem with two screws to the mounting surface at the desired location on the equipment. Multi-Tech Systems, Inc.
Chapter 2 – Installation 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. 2. Insert the SIM card into the holder. 3. Verify that the SIM card fits into the holder properly and then replace the cover.
Chapter 2 – Installation 4. Connect a suitable antenna to the SMA connector (see specifications on page 5). Antenna Connector (SMA type) 5. Connect both sides of the serial and control cable (15-pin Sub D connector on the modem side). Serial & Control Connector To Serial Port of PC Multi-Tech Systems, Inc.
Chapter 2 – Installation 6. Plug the power supply cable into the wireless MultiModem. Fused DC Power Cable In-Line Fuse 7a. For standard transformer power supply. Connect the AC cord receptacle into the transformer block. Connect the AC cord plug into the mains power outlet. 7b. For optional direct-DC powering. Connect the direct-DC power supply cable into the DC power source on the vehicle or machine in which you are mounting the MultiModem. Be sure the GND connection is correct.
