Use this article to install a Bullhorn RM3250 with the flat base.
Applies to: Bullhorn RM3250.
Steps
- Attach the flat base to a mounting bracket. Use an existing bracket or the optional adjustable bracket.
- If needed, mount the assembly to a structure, such as a pole, near the external device.
- Bring the wires from the external device up through the bottom of the flat base.
- Connect the external device to the 10-pin terminal.
- Connect the 10-pin terminal to its connection on the RM3250.
- Install the batteries into the bracket inside the RM3250 and secure them with the strap.
- Connect the two battery connectors to the board. The larger, round battery goes to P4. The bundled pair of batteries goes to P3. Once the batteries are connected, the unit sends a Startup packet to your Bullhorn Web account.
- Place the unit onto the base. Line up the cut-out below the Bullhorn label on the dome with the screw next to the blue dot on the base.
- Tighten the screws to secure the unit. Do not twist the dome if the cut-outs do not line up with the screws. Lift it off and set it down in the right position.
- Only if you use AC power: turn the rectifier on to restore power to field wiring.
Good to know
- Electrostatic discharge (ESD) can damage electronic parts. Wear an anti-static wrist strap attached to an unpainted metal surface when you open the unit or handle its electronics.
- Keep field wiring as short as possible, and use shielded twisted pair wire. American Innovations recommends AI part number 211061-000 (Belden 5308UE) or equivalent for wiring inputs.
- If wires will be buried or covered, protect them with conduit.
- If you plan to configure the unit with a USB 5-pin mini-b cable and not Bluetooth, configure it before you put it on the base.
Torque values
- Dome screws: 10 to 12 in-lbs.
- Cord grip body: 60 in-lbs.
- Cord grip gland nut: 30 in-lbs.
