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. For example, one might use two 6-32 self-tapping 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.
Chapter 2 – Installation 3. Slide the mounting brackets into the corresponding slots on the backside of the MultiModem chassis. NOTE: Some MultiModem units will be shipped with a single mounting bracket. Slide it through the channel on the MultiModem chassis and secure it with screws. 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 Inserting SIM/R-UIM Card into Holder (GSM Only) The wireless MultiModem requires a SIM card (Subscriber Identity Module) to operate on a GSM network.

Chapter 3 – Troubleshooting GSM/GPRS General FAQ The modem is answering, but seems not to be doing anything. What’s the problem? • • The modem is answering in voice mode. If you are trying to make a data call, make sure the account has CSD service. You will also need the data number (separate number from the main phone number given by the provider). I am trying to make a data connection by dialing from my wireless modem to an analog modem.
Chapter 3 – Troubleshooting The modem will not answer. • • • To have modem auto-answer, set modem with ‘ATS0=1’. Use ‘AT&W’ to store the setting. Send ‘ATA’ to the modem once the RING is indicated on the terminal screen. If you aren’t providing DTR, you may need to set the modem to ignore DTR by using this command: ‘AT&D0’ .
Chapter 3 – Troubleshooting GSM/GPRS FAQ on the IP Stack Whenever I send the # commands, I receive an error. • • • You must enable the stack before the modem will accept the # commands. ‘AT+WOPEN=1’ will enable the stack and ‘AT#VVERSION’ will display the version of the stack. If you receive an error when sending ‘AT+WOPEN=1’, then you may not have the stack present on the modem. How do I know if I have the stack? • Use the ‘AT+WOPEN=1’ command.
Chapter 3 – Troubleshooting FAQ for Mobile PhoneTools v2.1 What is the Mobile PhoneTools program? • A software developed by BVRP used for the GPRS & CDMA modems for voice, SMS, email, and Internet (packet-switched) connections. How do I make an Internet connection? • Click on Menu – Setup – Internet Connection; or click on the globe icon that says “Create Internet Connection”. Then follow the wizard.
