Cooper Bussmann BU-905U-L-T Transmitter Quick Start Guide

Resetting Your Unit to Factory Defaults

To reset the default factory configuration:

1.Set the RSSI rotary switch to position 0 using a screwdriver.

2.Power on the BU-905U-L-T transmitter.

3.The BU-905U-L-T transmitter flashes all LEDs at medium flash (i.e., 1.6Hz).

NOTE: If the LEDs do not flash, you must repeat steps 1 and 2 until the LEDs flash before continuing.

4.Set the RSSI rotary switch to another position (i.e. position 1) within 5 seconds.

5.Set the RSSI rotary switch to position 0 within another 5 seconds.

6.The BU-905U-L-T transmitter lights all LEDs for 2 seconds before returning to normal operation.

NOTE: If the LEDs do not light for 2 seconds, you must repeat the process from step 1 until the LEDs light before continuing.

7. You can now link the transmitter and receiver units.

Linking Your Transmitter and Receiver Units

You must reset the transmitter unit to factory defaults (to disable encryption) before linking the transmitter and receiver units. For more information, see the previous section.

NOTE: You must complete the linking process in 60 seconds.

To link the transmitter and receiver units:

1.Press and hold down the RSSI Pushbutton on the receiver.

2.Power on the receiver while holding down the RSSI Pushbutton

3.Release the RSSI Pushbutton as soon as the Receiver LEDs flash (within 5 seconds of powering the receiver).

4.The receiver will flash all LEDs for a maximum 60 seconds while it tries to link to the transmitter.

5.Power on the transmitter. The transmitter sends a special “Link” message to allow the receiver to recognize the transmitter.

6.When the units link, the receiver lights all LEDs for 2 seconds before returning to normal operation.

NOTE: If the receiver LEDs continue flashing within the 60 seconds, the units are not linked and you should retry the linking process by powering the transmitter off and on again. If you exceed the 60 seconds, you must restart the linking process from step 1.

7. You can now bench test your configuration before deploying.

Thank you for selecting the BU-905U-L-T transmitter for your telemetry needs. We trust it will give you many years of valuable service. To ensure your BU-905U-L transmitter enjoys a long life, double-check ALL your connections with the user’s manual before powering on the unit.

WARNING: Incorrect termination of supply wires may cause internal damage and will void warranty.

Exposure to RF energy is an important safety consideration. The FCC has adopted a safety standard for human exposure to radio frequency electromagnetic energy emitted by FCC regulated equipment as a result of its actions in Docket 93-62 and OET Bulletin 65 Edition 97-01.
