Connection to VBOX #

The Multi-Function Display has 2 LEMO connectors at each end. The top left and top right connectors share the same function and are used for connection to the VBOX CAN bus and to supply power to the display. The bottom left and bottom right connectors are serial connections. The function of these connectors is to allow firmware upgrade via a PC and to provide connection to a thermal printer for instant paper record of test results. Also in the serial connectors is a digital output, which will either send a pulse or toggle its state when a split line is crossed.

Mounting #

The MF display is supplied with a windscreen suction mount. This can be connected using the ¼ 20 fitting on the rear side of the display. Make sure the hole on the rear of the display that is used for the buzzer is not obstructed. 
 

Note: Exposing the windscreen mount to large changes in temperature over a prolonged period of time may cause loss of suction. We would recommend that the suction mount is removed when the days testing is complete.
