Power supply

The instrument is powered by 12V DC and draws 2.1A. Current is supplied with an IP67 waterproof Binder series 768 connector. Power on is indicated by a LED on the rear side of the instrument.

Communication interface

Measurement results are transmitted via RS232 and the series communication interface is bidirectional for reception of control instructions.

The RS232 interface uses 19200 baud, 8 data bits, one stop bit and no parity. Measurement results are transmitted from the instrument every 125ms using a proprietary protocol.

A 9 pin IP67 waterproof LTW D-sub connector is used, shown at the lower right side in the image.

Reset

The instrument is provided with a reset button, visible on the lower left side of the image below. Software controlled reset via RS232 is also available.

Ports not intended for customer use

A lid, shown at the centre of the image above, prohibits access to further ports that are not intended for normal customer use. The lid should not be removed.

The instrument is calibrated at production for optimal performance at ordinary use. It may be recalibrated using a switch behind the lid, but if incorrectly done it may reversibly affect performance negatively and this is strongly advised against.
