Planning the Installation of the Multitech GPRS/GSM Cellular
Modem
To install the Multitech GPRS/GSM cellular modem, you will typically need the following:
1. [__] The modem itself;
2. [__] The modem's documentation and drivers CD, in case you need to install the modem on your PC to verify
proper operation;
3. [__] USB cable to connect the modem to the AcquiSuite/AcquiLite DAS's USB port. Note that all of the USB
cellular modems mentioned in this document have USB “type-B” male plugs, so the necessary extension cable
would be a USB “type-A” male to “type-B” male.
4. [__] A PC (or other device with a full-featured web-browser) to be used to configure the modem via the
AcquiSuite/AcquiLite DAS's web user-interface.
5. [__] An Ethernet cross-over cable to connect said PC to the DAS's ethernet port.
6. [__] For GSM/GPRS modems, an appropriate SIM card, activated for the modem.
1. Note: SIM cards from personal cell phones may not work with data-only cellular modems. Ask your cellular
carrier about a data-plan account which is compatible with the specific Multitech Modem you plan to use.
2. Obvius strongly recommends that you verify the combination of the modem and SIM card are activated and
working properly before heading out to the field.
7. [__] Check that your data-plan limits match your intended usage with the DAS to avoid overage charges.
1. Note: Obvius recommends an unlimited data-plan.
2. Choosing an appropriate plan is your responsibility. Obvius is not responsible for any overage fees or
penalties that result from choosing an insufficient data-plan.
8. [__] The carrier-specific Modem Setup (if any) string needed to initialize the modem.
9. [__] The carrier-specific Access Point Name (APN), Account username and Account password.
10. [__] Proper mounting hardware (screws, etc.) to mount the modem with the antenna positioned for optimal signal
strength.
