LED Position Indicators

LED Position Indicators can be applied to a wide range of applications…

tabs • drives • jackplates • rudder indicators • water level • fuel level

These state-of-the-art indicators by Livorsi Marine, Inc. are capable of reading CAN Bus protocols such as SmartCraft® (with Gateway), NMEA 2000® as well as 0-5 volt or resistive-type (ohms) inputs. The technology used for these indicators can be applied to a wide range of applications such as trim tabs, drives, jackplates, rudder indicators, water level, or fuel level.

Power Supply:

Input supply voltage of 12 VDC, with reverse polarity protection

The LED position indicators eliminate the need for mechanical 33C cables which are typically used for drive and tab indication. These cables have a tendency to deteriorate, will fail over time, and are inaccurate due to lost cable motion. With the LED position indicator, mechanical cables are replaced by more reliable network wiring that allows 'plug n play' connectivity into existing tab or drive position sensors.

If you do not have drive trim or tab sensors, we have the solution. For applications or retrofits that do not have electronic position sensors, Livorsi can provide you with a mechanical to electronic converter solution so that you may take advantage of the accuracy and benefits of Livorsi's LED Position Indicators.

What sets these displays apart from anything else is the single middle green LED. During calibration, this LED display can be set to indicate 50% of actuator travel, fuel level or whatever you are monitoring. What makes it so special is that it allows you to establish the optimum running angle - or sweet spot (not at 50%), to dial-in the vessel for optimal running efficiency so the novice boater always runs at the correct trim.

No matter what information you are looking to display (fuel level, drive trim, tab position, etc.), the data is brought into the communication network (Rx) with 'plug n play' harnessing and is received via the network cable to the LED indicator for display. The LED indicator can also transmit (Tx) this information via CAN bus to other compatible displays such as Garmin, Lowrance or Raymarine via NMEA 2000® and SmartCraft® (with Gateway) protocols. If your boat is already transmitting (Tx) NMEA 2000® data (tabs, drives, fuel level, water level, rudder angle, etc.), simply plug the indicator into the NMEA 2000® backbone to begin displaying the desired feature on the indicator.

The super bright LED's can be seen in direct sunlight even with polarized sunglasses. With a range of 250 brightness intensity levels, you are guaranteed the best view possible, day or night. We accomplish this with the use of an ambient light sensor which provides automatic adjustment of the LED brightness according to available light conditions.

Setup of the indicator is performed via the proximity/ambient light sensor located on the front of the unit. Simple to follow and easy to use step-by-step instructions are included to ensure installation and setup is a snap.

By setting the 'running point', the indicator can more accurately track the entire range of operation, giving more resolution than if only a high and low point were known.

In order for these new indicators to function, there must be either an electronic sender to transmit the signal, or a mechanical to electrical device to convert the mechanical operation into an electronic voltage or resistance, which will ‘feed’ the signal to the indicator. Many of today’s tabs, drives, jackplates, fuel or water tanks, or rudders already have a sender on it. These versatile indicators can be used with a wide variety of senders such as voltage, resistance, or CAN bus NMEA 2000®, SmartCraft® or SAEJ1939 protocols. We have many ideas to adapt senders for these devices. Let us know your situation, and we will determine the best solution for your application.

The type of sender used whether voltage, resistance, or CAN bus must be known at the time of order with respect to how the indicator will be programmed to read the type of connection used.
