The data display is a DASH1 with special firmware to allow it to interface with the BRAKEBOX. The display comes with the correct connections so it can be connected to the main BRAKEBOX immediately. If a longer lead between the 2 units is required then a simple 9 way serial lead extension can be used. The vacuum type windscreen mount that comes with the display is exceptionally strong and provides an excellent mount to clean glass provided it is used correctly. The display is backlit for use in all lighting conditions. Note that for correct operation the display must be connected to the BRAKEBOX prior to power being applied. If this is not done and the unit does not start up, simply cycle the power off and on.
