NMEA OUTPUT

The Clipper Log has an NMEA output version 0183 sending
sentences $VWVHW and $VWVLW. The blue lead is the
NMEA output positive.

CLIPPER LOG REPEATER

Connect the Clipper Log Repeater as follows:

Red wire to positive (+12V)
Silver/Black wire to negative
Blue wire to Blue wire on Clipper Log master unit (NMEA)

The log repeater repeats all information from the Clipper log
master unit.

To set the display back light press the

ILLUM

key.

Pressing

ILLUM

whilst `L` is shown on the display will

gradually decrease the illumination. Pressing

ILLUM

whilst

`H` is shown will gradually increase the illumination.

A brief press of

ILLUM

will roster between ‘L’ and ‘H’.
