1.1 Introduction

The SL150 is a high quality digital speed log. It
mounts into a 1¼" (32mm) diameter instrument
hole.
The SL150 is capable of displaying speed readings
up to 50 knots or 58 miles per hour, permanent log,
trip log, trip time, and water surface temperature. In
addition, a programmable racing count down timer is
provided.
Both logs accumulate distance regardless of the
mode the instrument is in. The accumulated logs
are maintained in all modes until reset, even if
power is removed.

• Owners manual

pressed. All functions are controlled entirely by
these three keys.

1.3 Rear panel

The rear panel contains a Fuji 4-pin connector for
connection to the speed transducer. It also contains
red and black wires for connection to the power
supply and a blue wire for NMEA output for interfacing
with WS150 and RP150 or other NMEA listeners.
