Moreover, the USB port can also be used to update the firmware for additional features and improvements.

Mounting/ Installation
It is highly recommended that all the installation instructions are read before commencing the installation. There are important warnings and notes throughout the manual that should be considered before installation is attempted. Incorrect installation may invalidate the warranty.

The A037 was meticulously engineered for application in light commercial, leisure and fishing boat and vessel monitoring markets. Although the A037 comes with conformal coating on the circuit board, the pinouts are open so seawater and dust has the potential to cause a short circuit. It should be securely fitted, avoiding direct exposure to water and areas where salt and dust may come into contact.
The following installation points should be checked before commencing the installation.
· Cable disconnection. Do not mount the A037 while the device is powered and disconnect any sensors, cables or NMEA 2000 drop cables before installation.
· Avoid electronic compass interference. Maintain a minimum distance of 0.5 meters from any electronic compass (such as Quark-elec AS08) and ensure that the connection cable remains separate from it.
· Avoid proximity to antenna cables. While there is no specific minimum distance requirement between the A037’s connection cable and VHF or other antenna cables, it is advisable to maintain separation. Do not bundle them together in a single cowling.
· Minimizing wire noise. Avoid running noisy wires (such as those connected to ignition coils) adjacent to sensitive gauge or alarm wires as noise may be induced into these wires and this may result in inaccurate measurements.
· Consider all connection cables. All connections need to be considered and prepared before selecting a proper installation location.

Mounting Location
Select a flat location to mount the A037. Avoid mounting on uneven or contoured surfaces, as this could potentially fatigue the device casing.
Ensure that the A037 is mounted in a suitable location appropriately between the NMEA 2000 bus and the senders or gauges.
The A037 is compatible with both existing analogue gauges and standalone use.
For Use Without Analogue Gauges
When directly connecting the A037 to the sender for measurement (where analogue gauges are absent), follow these guidelines:
· Position the A037 close to the engine. · Ensure that the cable length between the sender and the A037 typically does not exceed 2
meters.

For Parallel Use with Existing Gauges:
If the A037 is used alongside existing gauges to complement displayed information, consider the following:
· Mount the A037 near the gauges (instrument panel). · Keep the cable length between the gauges and the A037 typically within 2 meters.
2.2. Case Dimensions
The A037 enclosure is made of IP56 insulation class 2 plastic. External dimensions are 150×85.5x35mm.

Figure 2 Typical system connections.

The A037 Engine Data Monitor & NMEA 2000 Converter has the following options for connection to inputs, outputs, and host devices.

3.1. Sensor Inputs

· PT1000/PT100 input. PT1000 is the most widely used RTD (Resistance Temperature Detector) sensor in many industries as well marine engines. RTD sensors are temperature sensors that operate based on the principle that the electrical resistance of certain materials changes predictably with temperature. PT1000 temperature sensors offer a superior solution for demanding temperature measurement applications where accuracy, stability, and reliability are paramount. The platinum-based construction, higher sensitivity, and wider temperature range make them indispensable tools in industries ranging from pharmaceuticals to aerospace. While PT1000 sensors come with certain challenges such as initial cost and calibration requirements, their benefits far outweigh the drawbacks in most scenarios.

While PT1000 typically come with two wires, variants with three or four wires are also available. The additional wires are used to compensate for the resistance of the connecting wires themselves, minimizing errors in temperature measurement caused by wire resistance. For many marine applications, two wires of PT1000 are the preferred option. For many marine applications, the standard two-wire PT1000 is adequate. Consequently, this manual predominantly addresses the implementation of PT1000 sensors with two wires. However, the A037 also supports three and four-wire PT1000.

Although most two-wire PT1000 sensors are not polarized. It’s good practice to check the datasheet for accurate connection details. Establish a connection by attaching one lead to the A037’s GND (either pinout 6 or 15) and the other lead to PT1000 (pinout 1).
Performing calibration on the PT1000 sensor before using is an essential step to ensure optimal functionality. This calibration process can be executed through the configuration settings on a Windows computer. More details can be found from PT1000 Sensor Input Section.

Figure 3 PT1000 wiring (two wires)
Similar to the PT1000, the PT100 is another widely used platinum RTD sensor, commonly employed across industrial, marine, and automotive applications. The wiring for the PT100 shares similarities with the PT1000 when connected to the A037 device.
· DS18B20 Input. The DS18B20 is a popular, pre-assembled waterproof temperature sensor with the sensing component enclosed at its tip, making it ideal for measuring temperatures in liquids or locations distant from the A037. Being a digital sensor, there is no concerns about signal degradation over extended distances, and there is no need for pre-calibration before use.
The DS18B20 operates on a 5V power supply, achieved by connecting its VCC to the 5V pinout on A037 (Pinout 14) and GND to either Pinout 6,15 or 23 on A037. Additionally, the DS18B20 has a data wire responsible for transmitting temperature data to the A037. Connect the Data wire to the DS18B20 pinout on A037 (Pinout 13). Before powering up, thoroughly verify the VCC and GND connections to avoid potential permanent damage to the DS18B20. Once properly connected and powered up, the DS18B20 will operate seamlessly.

Figure 4 DS18B20 wiring
· DHT11 Input. Similar as DS18B20, DHT11 is a very common digital sensor, which output temperature and humidity data. It is an ideal device to detecting ambient/engine room temperature and humidity. DHT11 is pre-calibrated and ready for use. The single data wire interface makes the integration with the A037 quick and easy. Its small size, low power consumption and up to 20-meter signal transmission making it the best choice for use on boats.
Same as DS18B20, The DHT11 operates on a 5V power supply, achieved by connecting its VCC to the 5V pinout on A037 (Pinout 14) and GND to either Pinout 6,15 or 23 on A037. Additionally, connect the Data wire to the DHT11 pinout on A037 (Pinout 12). Ensure to carefully review the connections before initiating the power-up process to prevent any possible permanent damage to the DHT11. Upon successful connection, the sensor will function smoothly.

· Four Tank level inputs. Resistive liquid tank level sensors are very commonly used to monitor the liquid level in boats water tanks. The A037 supports up to 4 tanks, which can be used to monitor fuel, fresh water, waste oil, live well and black water level. After connecting the sensors, the user will need to calibrate the sensor and setup the proper capacity value via the configuration tool.
· Five Voltage inputs. The A037 supports various voltage output sensors for engine and battery monitoring, capable of measuring parameters such as oil pressure, engine rotation rate, battery voltage, temperature and more. With five voltage channels, the device offers comprehensive calibration options, allowing users to create an 8-point calibration table or select a predefined industry-standard calibration table for the most common sensors and gauges.
· Two RPM inputs. Two RPM inputs can be assigned to Port and Starboard, whereas the analogue or pulse inputs can be independently assigned to both engines, as desired. RPM signals could come from different sources depending on the engine. They may come from an alternator output, the ignition coil, or pulse sender (diesel engines).
· Tilt/ Trim input. This resistive input can be connected to Tilt/trim sensor directly or the parallel with tilt/trim gauge to monitor the position of the engine position.
· Rudder input. Connect this input to rudder angle sensor to get the angle information. Prior to usage, users must calibrate the resistance data using the configuration tool.
· Coolant Temp input. This is a resistance input specified for temperature sensors, tailored for measuring coolant temperature with pre-configured settings available with the option to manually enter the values.
· Air Temp input. Similar to the Coolant Temp input, this is another resistance input channel specifically designed for air temperature sensors.
· Oil Temp input. Similar to the Coolant Temp input, this is the third resistance input channel specifically intended for oil temperature sensors. The input sensor data will automatically convert to the related PGNs, allowing it to be displayed on the multifunction displays (MFD).
· Shunt input (battery status) input. The shunt serves as a sensor for measuring the load or unload current in a battery. Connect this input in parallel with the shunt to monitor the battery status.

Alarm and Relay Output
· Two Alarm and relay outputs. Two relay outputs can be used to trigger warning devices, e.g. light, buzzer, alarm.

Communication Ports
· WiFi port. The A037 enables the users to input engine data via WiFi on a PC, tablet, or other WiFi-enabled device. The NMEA 2000 data is output via WiFi in PCDIN format. Please be noted that due to the nature of NMEA 2000 data, most engine data is not supported by NMEA 0183

format. In contrast, NMEA 2000, introduced after 2000, was designed with engine data support in mind, reflecting evolving industry needs.
· USB port. The A037 is equipped with a type-B USB connector and comes with a USB cable. This USB connector can be directly linked to a USB port on a PC. The USB port serves two main functions: configuration of the A037 and firmware updates. It’s important to note that the converted sensor data is not transmitted via the USB port.

3.4. NMEA 2000 Port
The A037 Engine Data Monitor features an NMEA 2000 connection, enabling it to integrate seamlessly with an NMEA 2000 network on the boat. The A037 reads all available sensor data, converts the received data to NMEA 2000 PGNs, and outputs these PGNs to the NMEA 2000 network. This allows the data to be easily read and displayed by other devices such as chart plotters, MFDs, and instrument displays on the NMEA 2000 network.
When a related sensor is connected and properly configured, the A037 outputs the following PGNs:

Figure 8 PT1000 RTD Sensor Probe

Upon connecting the temperature sensor to the A037 for the first time, it’s essential to use the windowsbased configuration tool, which can be downloaded from our website, to configure the A037 to seamlessly work with the PT1000 sensor. This will allow accurate conversion of the sensor’s signal to the NMEA 2000 PGN(PGN130312) for precise monitoring and data transmission.
In addition to the PT1000, the PT100 is also a popular platinum RTD sensor, frequently utilized in diverse industrial, marine, and automotive applications. When connected to the A037 device, the wiring, settings, and calibration procedures for the PT100 is similar as for PT1000. This manual primarily focuses on the detailed description of the PT1000, which can be utilized as a reference for working with the PT100.

6. Voltage Sensor Inputs
There are various voltage output sensors used for engine and battery monitoring, that can monitor oil pressure, engine rotation rate, battery voltage, current, temperature and so on.
The A037 features five independent voltage input channels, which can be connected to voltage output type sensors. Like Tank level sensors input, these five voltage inputs have comprehensive calibration function that allow you to create a 10-points calibration table.
Once the voltage sensor has been connected to one of the sensor input pinouts, the configuration tool (Windows PC application ­ can be downloaded from Quark- elec website) must be used to calibrate the sensor and to assign the correct input to the output data. The output voltage value from voltage sensor is converted to the NMEA 2000 PGNs by the A037.

6.1. Input Pinout Settings
The A037 supports up to 32VDC input voltage. A sensor typically is using two wires or pins to output, one is used for the output voltage, the other is for GND. Connect the output voltage wire to one of the voltage input pinouts (e.g., in below example its V2 input, Pinout 8) and the other wire to one of the GND pinouts (Pinout 6 or 23). The below details how to set up this pressure sensor. A voltage output pressure sensor generates an electrical signal corresponding to the pressure it measures. Typically, this signal is a direct current (DC) voltage, providing a ratiometric value relative to the measured pressure. Such sensors are frequently used in marine, automotive applications due to their commonality and effectiveness.
Here, an illustrative example is provided for setup a 0.5V to 5V pressure sensor.

1. Please ensure that all your electronic devices are switched off and disconnected from their power supply, to avoid creating a short circuit during the installation process. Connect the output of the pressure sensor to Pinout 8 and the other pin to GND (Pinout 6,15 or 23) of A037.
2. Power up the A037.

6.2. Calibration
The “Calibration” tool can be used to read and view the sensor data (in this example, its voltage), output by the sensor. This is required when setting up the “Data Output Set” table with the sensor data and the corresponding value to be displayed. The “Data Output Set” can be defined in the following way (as shown on the figure above)
1. The sensor’s manual or datasheet should contain a data table or graph showing the sensor’s voltage output in relation to the measured value. Please use this information to fill in the “Data Output Set” table in the configuration tool. In this example, for a measured value of 0.5, the A037 will output 0 Bar. For 1.5, the A037 will output 1.72 Bar, etc..
2. Start with the minimum value, a total number of ten “measured data: pressure value” pairs can be added to the data table. The last value added to the “Data Output Set” should be the maximum voltage value that the sensor can output. Spread the “measured data: pressure value” data pairs evenly through the sensor’s voltage output range.

7. Tacho Inputs (RPM)
The A037 supports two RPM inputs, which is suitable for use with the majority of boats equipped with two engines. The tacho inputs, RPM1 and RPM2 of A037 can measure RPM data from the engine. Both are designed to be connected to existing engine senders either with or without the gauge connected.
RPM signals could come from different sources depending on the engine. They may come from a ignition coil, alternator output, or electronics pulse sender. The A037 supports most of these, however the wiring methods may vary.
7.1. Ignition Coil
The following diagram shows how to connect the A037 to an ignition coil or alternator output signal or a single wire flowmeter. Connect the negative connection of the ignition coil to the RPM. And connect GND to GND of A037. If there is only one wire from ignition coil or alternator, then just don’t connect this. Single wire (negative connection) is sufficient.

Figure 22 Ignition coil wiring
7.2. Alternator
Connect the Tacho (also called AC Tap or marked as “W”) connection of the alternator to the A037 RPM input. Connect GND to GND of A037 if applicable.

Follow the steps below to set up the RPM input:

V 1.0

21 of 44

2024

A037 Manual
1. Click on “Input Pinout Settings” tab and select the “RPM 1: Pinout(25)” or “RPM 2: Pinout(24)” option from the dropdown menu, to which pinout the sensor is connected.
2. The Physic Variable and Units fields will be automatically filled in. These parameters cannot be changed. Enter the engine’s minimum and maximum RPM values. Select “-Sensors-” from the Sensor Type list.
3. Start your engine and keep it running.
4. By clicking on the Measure button, the configuration tool will display the pulse value(Hz) received from the engine/Tacho. In this example, it is measured as 30, while the engine is running at 1800PRM. This indicates that the engine or tacho is outputting a 30Hz signal at 1800 RPM. So, in the “Data Output Set”, set marker as 1800(30hz times 60 seconds) and the related value as 1800.
5. Repeat the above step multiple times to get a few more marker/value pair. In most cases, you will find these values are in liner patten. For example, when the engine runs at 3000 RPM, the output pulse is 3000/minutes(50Hz).
6. Fill above value pair into “Data Output Set” and put “o” and “o” in the first line and calculate the maximum value based on the above values using liner patten.
Practically, you may find that step 5 is unnecessary. Instead, you can obtain the Tacho PPR (Pulses Per Revolution) from the engine datasheet, or a plaque affixed to the engine. From there, you can calculate the relationship between the marker and the value. Below, you’ll find a general rule that can serve as a reference, but it’s advisable to verify this before finalizing the settings.
· For an ignition coil it can normally be counted as: PPR = (No. of cylinders × 2) / (No. of strokes × No. of ignition coils)
· For an Alternator (“W”. “R” or “AC”) pinout connection it can be counted as: PPR = (Crank pulley diameter / Alternator pulley diameter) × (No. of poles in Alternator / 2)
· For a hall effect or inductive sensor, it is derived from the number of teeth on the flywheel: PPR = No. of teeth on flywheel
7.5. N2K Output Settings
Once the calibration process completed, the next step is to activate the NMEA 2000 PGN which contains the RPM information. This can be done as shown below:
1. Click on the “N2K Output Settings” tab and select the “PGN 127488: Engine Rapid Update” option from the dropdown list.
2. For the first engine select “Instance 1 – Port” (for the second engine “Instance 2 – Starboard”, etc.)
3. For Engine Speed select the pinout to which the sensor is connected. In this example this is “RPM 1: Pinout(25)”.
4. If Engine Boost and/or Tilt/Trim data is also available for this engine, these can also be added to the PGN by selecting the pinouts to which these sensors are connected.
5. The last step is to tick the box next to “Enable PGN” and to click Save to save the new settings to the device. Repower the A037 Engine Data Monitor after the setup process to activate the new settings.

2. Set the Physic Variable to “Current”, the Units to “A” (Amps). 3. Set the Max Value to 100 and the Min Value to 0, if a 100 Amp shunt is being used. 4. The sensor type should be left on “-Sensors-“. 5. The “Data Output Set” table can be filled in based on the measured data. Start by filling in the
first row with a Marker value of 0 and a Value of 0. 6. Switch on one device or instrument, click Measure to read the sensor value and read the current
from the A016’s display. Fill in the second row with this data ­ the measured value into the Marker column, the current value into the Value column. If you have more than nine devices onboard, two or more devices can be switched on and added to the same measurement. 7. The configuration tool allows a total of nine measurements to be added to the “Data Output Set”. The last Marker: Value pair should be filled in with the measured value and the electrical current value measured with all devices and instruments switched on. 8. Click Save, to save the new data to the device.

9.1. Input Pinout Settings
The rudder input allows the customer to connect an existing resistive type of rudder angle sensor installed on a rudder and provides the rudder angle to NMEA 2000 autopilots, chart plotters and other devices. The A037 can support most rudder angle sensors in the market, including European (10 to 180 Ohm range) or American (240 to 33 Ohm range) standard sensors. The A037 can be installed as a standalone measuring rudder sensor data or work together with an existing analogue gauge.
9.2. Calibration & N2K Output Settings
The rudder angle readings can be calibrated with up to 10 calibration points to compensate for nonlinearity of the sensor’s resistance value vs rudder angle. To set up the rudder angle sensor with the A037, the data displayed by an existing rudder angle gauge can be used if this gauge displays the angle accurately, in degrees. If not, the rudder angle will have to be measured during the setup. The A037 can be set up to convert sensor data to an NMEA 2000 PGN as shown below:

The A037 allows sensor data to be broadcasted to a laptop, smartphone, or tablet via WiFi in PCDIN format. This is a very helpful feature when marine electronics technicians, engineers and installers are required to do data monitoring, troubleshooting or faultfinding work. The A037 supports the following three WiFi working modes: Ad-hoc, Station and Standby(disabled).
· In Ad-hoc mode, wireless devices can be directly connected to the A037’s WiFi network (peer to peer) without a router or access point.
· In Station mode, wireless devices communicate through an access point (AP) such as a router that serves as a bridge to other networks (such as the Internet or LAN). This allows your router to handle the data and traffic from your A037. This data can then be picked up through your router anywhere on your local area network. It is similar to connecting the device directly to the router, but using wireless technology. This way, the mobile devices can receive both the sensor data from the A037 and other AP connections such as Internet.
· In Standby mode, the WiFi connection is disabled.
The A037 is set to Ad-hoc mode as a default setting but can be easily set up to Station or Standby mode through the configuration tool. To check or to modify the WiFi settings, power up your A037 and connect it to your Windows computer via USB. Download the A037 configuration tool from our website and launch it on your computer. The A037 should automatically connect to the configuration tool and the “Connected” status message together with the device firmware should be displayed at the bottom of the configuration tool window.

To enable the A037 to output data via the NMEA 2000 network, you must ensure that the “N2K Output Settings” have been configured correctly. All supported N2K PGNs are listed in the drop-down tab, with detailed setup instructions available in the
related input sensor sections (Section 4 to Section 11).

After settings have been chosen, click “Save” and restart A037 to enable the changes to take place.
15. Upgrading Firmware
The current firmware version can be verified through the configuration tool (When connected, the firmware version will show in the bottom of the Configuration software window). The A037 operates with two firmware versions: one for the main board and an additional for the WiFi module. Upgrade the main board firmware (MCU) to access the latest features. The WiFi Module must be updated ONLY when instructed to do so by Quark-elec.
The user must take great care to ensure the correct firmware version is being applied to the appropriate module. Improper operation may result in the module freezing. In such cases, the A037 will need to be returned to us for repair to restore functionality.
To upgrade the MCU firmware, 1. Power up your A037 and then connect it to a Windows computer via USB. 2. Run the Configuration software. 3. Ensure the configuration tool is connected to the A037, and then press Ctrl+F7. 4. The following message will pop up on your screen:

Figure 49 Upgrading firmware
Click OK to continue with the firmware update. 5. Two new windows will pop up with a disk drive named “STM32(APP)” and the other called
STM32(WiFi) or similar. Copy the firmware into STM32(APP) drive and wait around 10 seconds to make sure the full file has been copied. In no circumstances must you copy to STM32(WiFi) as this could leads to freezing the product. 6. Close the window and the Configuration software. 7. Re-power the A037, and the new firmware will be active.
16. Factory Reset
Due to different reasons, it might be required to restore the A037 to its factory settings. This might be required if the A037 is transferred to another boat equipped with different type of sensors or if the boat is being refitted with a new set of sensors and devices. In these cases, the CTRL+F5 key combination can be used to delete all settings, instead of having to reset all settings manually.
To restore the A037 to its factory settings, please follow the steps below:
1. Connect your A037 to your computer via USB and power up your device.
2. Launch the configuration tool on your computer. 3. Ensure that the “Connected” status message is being displayed by the configuration tool,
together with the actual firmware version of the A037.
4. Press CTRL+F5 (on laptops CTRL+Fn+F5 key combination will have to be pressed).
5. A message will pop up on your screen asking if you would like to restore your device to its factory settings. Please confirm.
6. Wait for a few seconds, a new message will pop up on the screen confirming that your device has been restored to its factory settings.
7. Repower your A037.
Your device should now be restored to its factory settings.

21. Glossary
IP: internet protocol (ipv4, ipv6). IP Address: is a numerical label assigned to each device connected to a computer network. NMEA 0183: is a combined electrical and data specification for communication between marine electronics, where data transfer is one-directional. Devices communicate through talker ports being connected to listener ports. NMEA 2000: is a combined electrical and data specification for networked communication between marine electronics, where data transfer is one-directional. All NMEA 2000 devices must be connected to a powered NMEA 2000 backbone. Devices communicate both ways with other connected NMEA 2000 devices. NMEA 2000 is also known as N2K. ADC: Analogue-to-Digital Converter Router: A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet. WiFi – Ad-hoc mode: devices communicate directly with each other without a router. WiFi – Station mode: devices communicate by going through an Access Point (AP) or router. PGN: Parameter Group Number ­ refers to numerical IDs used to define different data groups used by NMEA 2000 devices to communicate. MFD: Multi-function Display ­ integrates and can control various marine electronic devices including chart plotters, radars, fish finders, GPS receivers, AIS receivers or transponders, etc. RPM: revolutions per minute is a unit for rotational speed. PT1000: is a type of resistance temperature sensor. DS18B20: is a digital temperature sensor. It is widely used due to its simplicity and accuracy. DHT11: is a digital temperature and humidity sensor used for environmental monitoring.
