Introduction
The SLT110 provides accurate digital instrumentation for boat
speed and average boat speed, trip distance and total distance
traveled, water temperature, elapsed time and provides a race
timer that can be preset to two different (pre-programmable)
values.
TheSLT110displaysspeedandaveragespeedupto50.0Knots
(58 M.P.H.) in tenths, very accurate water temperature in
degrees F or C in tenths, trip log to 999.9 miles and permanent
logto9,999miles. Adowncountingracetimerispresettablefor
two different start times from 1 to 99 minutes each. It beeps off
the minutes and last ten seconds before reaching zero. After
reaching zero, the race timer continues to track elapsed time.
Speed can be displayed in Knots, MPH and KM/H with
selectable display damping. Temperature can be displayed in
degrees Fahrenheit or Celsius. Speed, temperature and clock
speed may all be calibrated using the front panel keys.
Five levels of backlighting can be selected and remotely
switched ON/OFF. All setup and calibration constants are
saved to a non-volatile memory. The SLT110 outputs NMEA
0183 data of boat speed, logs, and water temperature and works
on both 12 and 24 VDC systems.
The SLT110 with its large display digits draws only .035 amps
andonly.055ampswithfullbacklighting. Bothtransommount
and thru-hull mount speed/temperature transducers are avail-
able separately.

Installation
Before starting the installation, please read this entire section
first. Finger tighten the screws that mount the instrument
bracket - It is not necessary or recommended to use tools.
lDrill a 2-1/8" (55mm) mounting hole where you desire to
mount the instrument (Figure 1).
lConnect the various wires from Cable 1 and Cable 2 as
shown in Figures 2 and Figure 3.

T and Q) keys are used to select
what to display, set backlight levels, calibrate speed, tempera-
ture and clock speed and set/change constants and units of
display. Newinformationisautomaticallysavedtonon-volatile
memory.
BacklightIntensity
Press :the key 1/2 second to adjust the backlight level for
night viewing. Each time you press the :key 1/2 second, the
level will get brighter 1, 2, 3, 4, OFF, 1, 2, ... etc. The blue
backlightON/OFFcontrol wire incable#1 must be switched
to +12/24V for the backlights to work and offers external
backlight ON/OFF control. If ON/OFF control is not
required, connect the blue wire to +12/24VDC permanently.

Lkey again while displaying the
distance traveled log will toggle the display between total
distancetraveledandtripdistancetraveled. Thetriplogdisplays
with a decimal point such as "82.3" and the permanent log
displays to a full digit such as "562" so you always know which
log you are viewing.

Display Average Speed
Press the Skey for a second time to display the average speed
An “A” will be displayed above the speed to indicate Average
Speeddisplay. Thedampingusedtocomputetheaveragespeed
is adjustable and can be set between 1 and 20 (see page 10).
Display Trip Log
Press the Lkey for a second time to display the trip log. The
trip log displays with a decimal point such as "82.3" and the
permanentlogdisplaystoafulldigitsuchas"562"soyoualways
know which log you are viewing. Each time you press the L
key the display will toggle between Permanent Log and Trip
Log.
Display Elapsed Time
Press theTkey for 1/2 second to displaythe elapsedtime since
the instrument was turned on. When the elapsed time exceeds
60 minutes, the elapsed time clock displays hours and minutes
in place of minutes and seconds and the semi-colon flashes.
Resetting the Trip Log/Elapsed Time Clock
While viewing the Trip Log, press and hold the :key for 10
seconds (till you hear a long beep) to reset both the trip log and

elapsed time clock to zero.
Display/Start/Setting the Race Timer
The race timer can be started with one of two different values
between 1 and 99 minutes (factory preset to 5 and 10 minutes).
To start the timer with the first value, press both the tand :
keys. The display will start counting down from 5:00, beeping
at each minute and for each of the last ten seconds. To start the
timer with the second (10 minute) value, press both the :and
skeys simultaneously.
If the timer was already running, the current value is displayed.
To stop and preset the timer, press the appropriate key
combination(tand:or the:andskeys). Torestartthetimer,
press the appropriate key combination again.
The race timer start times are factory preset to start at either 5
or 10 minutes. To change the first start value, press and hold
the tand :keys for ten seconds and use the tand skeys to
adjust the first start value to any number between 1 and 99
minutes. Press the : key to save the new value to memory.
To change the second race timer start value press and hold the
:andskeysfor ten secondsand use thetandskeysto adjust
the second start value to any number between 1 and 99 minutes.
Press the : key to save the new value to memory.

CalibratingSpeed
To calibrate the displayed speed value, press and hold the Skey
for ten seconds while viewing boat speed (until you hear a long
beep). Usethetand s keystoadjustthevaluetoreadcorrectly.
Press the : key to save the new value to memory.
Selecting Speed & Log Units of Measure
While viewing Speed, Average Speed, Trip Log or Permanent
Log,simultaneouslypressboththetandskeystostepthrough
U1(Knots/N miles),U2 (MPH/Miles) and U3(KPH/Km). The
units of measure for the logs will automatically be adjusted
according to the chosen units of measure for the speed.
Selecting Average Speed Damping
Press and hold the tand skeys for ten seconds while viewing
Average Speed (until you hear a long beep). Use the tand s
keysto adjustthe Speed Dampingvalue toany numberbetween
1 and 20. Press the : key to save the new value to memory.
The factory default Speed Damping is set to 10.

Calibrating Temperature
To calibrate the temperature value, press and hold the Tkey for
ten seconds while viewing water temperature (until you hear a
long beep). Use the t and skeys to adjust the value to read
correctly. Press the : key to save the new value to memory.
Selecting Temperature Units (Deg. C/F)
While viewing water temperature, press both the tand skeys
to toggle between Cand F.
Calibrating Clock Speed
While viewing Elapsed Time, press and hold both the tand s
keysforten seconds(untilyouhearalongbeep). Usethetand
skeys to adjust the displayed value UP and DOWN from 50.
Raisingthe valueabove50makestheclock runfaster,lowering
the value below 50 makes the clock run slower. Press the :
key to save the new value to memory.

NMEA 0183 Sentences
The SLT110 outputs serial data of boat speed, water tempera-
ture and both permanent and trip logs in NMEA 0183 serial data
format. The sentences are output in the following formats:
Water temperature (C): $VWMTW,xx.x,C*CS
Total/Trip Logs (N.Mi): $VWVLW,xxxx,N,yyy.y,N*CS
Speed (Knots/km/h): $VWVHW,,,,,xx.x,N,yyy.y,K*CS
