Installing the RM3250

Electrostatic Discharge (ESD) can damage electronic components. Provide ESD protection by wearing an anti-static wrist strap attached to any unpainted metal surface before accessing the unit or handling electronic parts. If an anti-static wrist strap is unavailable, discharge static electricity from yourself and your clothing by touching a nearby metal surface before accessing the unit or handling electronic components.

The following section explains how to install the RM3250 with the flat base. For alternative installation options, please contact Technical Services (support@aiworldwide.com).

To ensure a clean stable reading, keep field wiring as short as possible and use shielded twisted pair wire such as Alpha 2463C. American Innovations recommends using AI part number 211061-000 (Belden 5308UE), or equivalent, for wiring inputs.

Complete the following steps to install the RM3250:

  1. Attach the flat base to a mounting bracket (either an existing bracket or the optional adjustable bracket).

  2. If necessary, mount assembly to a structure, such as a pole, which is near the external device.

  3. Bring the wires connecting the external device up through the bottom of the flat base.

  4. Connect the external device to the 10-pin terminal.

  5. Connect the 10-pin terminal to the corresponding connection on the RM3250.

    1. Connect the larger, round battery to the P4 connection.

    2. Connect the bundled pair of batteries to the P3 connection.

    Once the batteries are connected to the unit, a Startup packet is sent to yourBullhorn Web account.

  8. Place the RM3250 unit onto the base. Align the cut-out below the Bullhorn label on the dome to the screw (next to blue dot) on the base.

    If you plan to configure the unit using a USB 5-pin mini-b cable instead of Bluetooth, do not place the unit on the flat base. Configure the unit first and then secure the unit on the base. Refer to RM3250 Configuration for configuration instructions. Otherwise, continue with next step.

  9. Optionally, you can test the satellite signal before completing the installation. Refer to Testing Cellular Reception and then continue with the next step.

  10. Secure the unit by tightening the screws. Torque the dome screws and fitting to the following measurements:

    • dome screws - 10-12 in-lbs.

    • cord grip body - 60 in-lbs.

    • cord grip gland nut - 30 in-lbs.

    Do not twist the dome on the base if the cut-outs do not line up with the screws. Lift the dome off of the adapter and replace it in the correct position.

    Only if using AC power — turn rectifier ON to restore power to field wiring.
