Use this article to install a Bullhorn RM4210 or RM4250 on top of a coupon test station.
Applies to: Bullhorn RM4210 and RM4250.
Steps
- Remove the protective cover over the test station head.
- Connect each wiring harness wire to its test point on the test station. Stay within the input limits listed below. The wires are color-coded and labeled for a Triton coupon test station. On other test stations: do not connect the orange AC Cpn wire unless you use a separate AC coupon, and keep the blue and red Test Cpn leads on the same connection. On Triton coupon test stations only, disconnect the wire from the Switch.
- Slip the test station adapter over the test station. Rotate it clockwise to secure it.
- Drop the tether cord attached to the unit down into the test station. Make sure the tether end catches across the diameter of the test station. The tether supports the unit if the test head needs to be opened later.
- Install the batteries into the bracket inside the unit and secure them with the strap.
- Connect the 8-pin terminal to its connection on the unit's board.
- Optional: connect a DC input or solar panel to the DC/Solar connector on the unit's board.
- Place the unit onto the adapter, carefully wrapping the wiring harness inside the dome. Line up the cut-out below the Bullhorn label on the dome with the screw next to the blue dot on the adapter.
- 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.
- For the RM4210, test satellite reception.
- Configure the unit for service.
Input limits
Stay within these limits to prevent damage to the unit:
- Voltage inputs must not exceed 100 V AC or DC.
- Current inputs for AC and DC current density must not exceed 0.2 A AC or DC.
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.
- The test station adapter fits test stations with a 3 inch diameter.
- Leave enough working space around the site to wire inputs, configure the unit and do routine maintenance.
- Place the unit in an area clear of obstructions. The RM4210 communicates by satellite and needs a clear view of the sky. The RM4250 communicates over a cellular network.
- Use only accessories that meet American Innovations specifications.
- Common harness connections: white Structure wire to the structure connection, yellow Ref Cell wire to the reference cell connection, and black Native Cpn wire to the native coupon connection. If there is no native coupon, cap off the black wire.
