Introduction The MaxDS110 multifunction depth/speed instrument will simultaneously display three sets of data on three digital displays. Depth, boat speed, sea water temperature, trip and total logs, race timers, time-of-day, elapsed trip time and battery voltage can be displayed in a variety of different formats. High and Low alarms can be set for Depth (Deep and Shallow), boat speed, water temperature and battery voltage.
Installation and Wiring 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. Drill a 2-1/8" (55mm) mounting hole where you desire to mount the instrument (Figure 1).
OFF - the clock will keep running. Press and hold the for three seconds to re-enable the display. If you remove power from the MaxDS110 the Time-Of-Day clock will have to be set again. Changing and Controlling Backlight Intensity Press the : key for 1/2 second to adjust the backlight level for night viewing.
Summary of Display Configurations 1-16 Each time you select a new display configuration the Current Display Configuration number (in this case #1) is displayed for one second as shown in Figure 3. After one second the display shows the data for display configuration #1 as shown in figure 4.

Turning Alarms ON/OFF To “arm” the alarms, press and hold the key 1/2 second. The Bell symbol will be displayed when the alarms are “armed”. To disable the alarms press and hold the key for 1/2 second. Any press between 1/2 and 2 seconds will work.
Be sure to read the warnings about alarms in the Important Notes and Warnings section about which Data Sources and conditions will sound an audible alarm. Setting/Starting Clock/Time-Of-Day Alarms/Race Timers Press and hold both the keys for ten seconds (until you hear a long beep) to view and/or set the clock, time-of-day alarms and Race Timer1/Race Timer2.

Figure 23 shows what you will see when setting Race Timer 2. The race timers are set the same way as the clock. Only the minutes can be set for the race timers. Press the + key for 1 second when you are done to save the results to memory.
Calibrating a Data Source Calibrating the displayed data is possible for boat speed, sea water temperature, battery voltage and the clock. Press and hold the keys for ten sec- onds to enter the Calibration Editor (until you hear a long beep). The data source value, display identifier (1, 2 or 3) and the word “CAL”...
If the selected data source cannot be calibrated (such as Elapsed Trip Time) then “---” will be displayed for the Data Source value as shown here. Figure 25 - Calibration Editor Sample display when attempting to calibrate a Data Source that cannot be calibrated.
Figure 26 - Display Damping Editor Setting the Damping Value to “7” for the Data Source shown on digital display #3 Setting Units of Measure Units of Measure are factory set to Feet, Knots and Degrees F. The clock is set to display in 12 hour format.
Setting Keel Offset You can enter a Keel Offset value between -50.0 and +50.0 Feet/Meters or Fathoms to modify the depth display. Entering a negative number enables you to display the depth below the keel instead of the depth below the transducer. Entering a positive number enables you to display the actual water depth below the surface instead of the depth below the transducer.
Appendix A - Specifications Power supply: 12/24 VDC (9.5 to 33.0), 0.10 A nominal Operating temperature: 32 to 122 F ( 0 to 50 C) Size: 4.3" x 4.3” x 3.5” deep (110 x 110 x 89 mm).

Appendix B - Packing List The MaxDS110 package is supplied with the following items: 1) MaxDS110 instrument. 2) Dust/rain cover. 3) Closed cell foam waterproof bulkhead gasket (adhesive one side). 4) Printed user manual. 5) Warranty card. Page 24...
Appendix C - Optional Items A number of different transducer options are available for the MaxDS110: Depth Transducer Options: 1) ATB120A - 450 ft bronze thru-hull ACTIVE NMEA 0183 transducer. 2) ATB120B - 1000 foot bronze thru-hull ACTIVE depth NMEA 0183 transducer.
Appendix E - Important Notes and Warnings The front of the MaxDS110 is splash proof. The back is not sealed and must be protected from water. The nonvolatile memory in the MaxDS110 will retain data for a minimum of 10 years without power.
Page 29
The Time-Of-Day clock will have to be set again if you remove power to the MaxDS110 but all other data is saved to a nonvolatile memory and not lost. 9) After settings are changed it can take up to 30 seconds to save the data to the nonvolatile memory.
Appendix F - Critical Background Alarm Functions In addition to sounding the alarms for the functions currently being displayed, the MaxDS110 always monitors the following “Critical” functions in the background regardless of what is being displayed on the screen. The alarm will sound only if the alarms are armed, however.
