6.2.2.1 Cellular Communication Option

Note: To ensure reliable communications between the sampler and the host computer, it is required that the host computer is equipped with a Cellular Compatible modem, it must support the MNP.10EC protocol. Computers equipped with modems that do not support this protocol are able to connect to the sampler but will not be able to maintain a reliable connection.

Note: If the display on the cell phone is not present, check to make sure the cell phone power is enabled in the setup of the sampler. Also check to make sure that the sampler is connected to a power source and is turned on.

This option couples the sampler to an external, 3-watt, cellular phone. The cellular phone is mounted in a NEMA 4X enclosure and is powered through the sampler by the sampler power supply. Enabling Modem Power also provides power to the Cellular Communication via a connector cable.

The cellular phone is set to activate upon an alarm. Additionally, the end user can use the phone to make cellular voice calls directly from the installation site as needed.

Site Selection

The quality and availability of cellular service varies considerably from one geographical location and from day to day. Factors that affect the quality of cellular service include but are not limited to: weather, time of day, distance to the nearest cell tower, other cellular traffic, etc.

Installation and Setup

1.Connect the four conductor cable between the four pin connector on the side of the cellular phone housing and to the connector in the side of the sampler case labeled MODEM. This cable supplies both the data and the 12 V dc power for the cell modem.

2.Attach the magnetic base cell phone antenna to any flat metal object in the immediate area. For optimum performance, mount the antenna in a vertical position.

Note: Mount the antenna as high and as far away from the sampler as possible. RF power radiated during transmission by the cell phone antenna in close proximity to the sampler may have adverse affects on data measurements.

3.When necessary, reposition the antenna to obtain optimum signal strength.
