Introduction
The M4 is our heavyweight acoustic receiver, combining the latest digital signal processing with the smartest software. This means that true multifunction channel operation is available and there is no compromise between transmission range and signal detection. We have designed the M4’s multifunctional capacity to accommodate a series of full-function channels allowing simultaneous use of standard sensors, net sounders – including narrow band – and high resolution net sounders. All of these are available over an extended frequency range and with selectable configurations for ultramodern net monitoring systems.
The M4 incorporates a host of features that are ready to be implemented, including sensor crossreferencing for positioning and distance, and sensor remote control.
The M4 receiver is built to be configured and upgraded using standard software tools and operated with Mac OS, Firefox® web browser and Java™ Runtime Environment (JRE).

‡ Add as NC-1-07 in the system web page.
Connecting the Hydrophone to the Receiver
You need to connect the hydrophone to the receiver to be able to display sensor data received by the hydrophones.
Procedure

• Connect the extension cable of the junction box to a hydrophone input on the receiver:
• Using an NMEA converter junction box (P/N: NC-2-TEMP), connect to the hydrophone input 1 or 2 at the back of the receiver to be able to receive water temperature from Marport hydrophones.

Note: Hydrophone inputs 1 and 2 allow to receive temperature from an NMEA connection, so you need an NMEA converter junction box. If you connect to other hydrophone inputs or have no NMEA converter, you will not have temperature data from Marport hydrophones.
Adding Temperature Data from the Hydrophones to the System
You can add the hydrophone to the receiver as a sensor in order to display in Scala/Scala2 the temperature of the water surface.
Before you begin
Important: In order to receive temperature data, make sure the hydrophone is connected to an NTC input on the receivers or is connected using an NMEA converter junction box. See Connecting the Hydrophone to the Receiver on page 22 for guidelines.
Procedure

1. From Scala/Scala2, click Menu > Expert Mode and enter the password copernic.
2. Click Menu > Receivers.
3. Right-click the IP address of the receiver at the bottom of the page, then click Configure Receiver.
4. From the left side of the page, click Sensors.
5. Under Add Sensor Product:
   a) Select Hydrophone in the Product Category menu.
   b) In the Product Name menu, select NMEA temperature if using an NMEA converter junction box, or NTC temperature if the hydrophone is connected to an NTC input.
   c) In Hydrophone Location, select the number of the receiver’s port on which the hydrophone is connected.d) Click Add Sensor.

Results
The water temperature is displayed in Scala/Scala2, in the control panels, under Sensors Data / Mx.

Understanding Receiver LEDs Boot sequence
When you power on the receiver, the LEDS on the receiver must light up the following way:

• Hydrophone LEDs become blue / red / green.
• LED in the letter A becomes blue / green / red, then stays red.
• When data are emitted or received, ETH LED blinks green.

Hydrophone LEDs
The LEDs on the hydrophone inputs identify the type of hydrophone that is connected to the receiver.

• Blue: passive hydrophone
• Red: active hydrophone
• No light: no configured hydrophone

Frequencies and intervals

The diagrams below show the bandwidth of the different types of Marport sensors and intervals you must respect when adding other sensors.Figure 1: PRP sensors (e.g. Catch sensor, Trawl Speed, Spread sensor…)
Example: If the frequency of the sensor is 40kHz, there should be no sensors between 39.9-40kHz and 40-40.1kHz.Figure 2: NBTE sensors (e.g. Speed Explorer, Trawl Explorer, Catch Explorer, Door Sounder)
Example: If the frequency of the sensor is 40kHz, there should be no sensors between 39.8-40kHz and 40-40.6kHz.Figure 3: HDTE narrow band mode
Example: If the frequency of the sensor is 40kHz, there should be no sensors between 39.8-40kHz and 40-41kHz.
Figure 4: HDTE wide band mode
Example: If the frequency of the sensor is 40kHz, there should be no sensors between 39.8-40kHz and 40-42.6kHz.

Examples of frequency allocations

• We recommend to allocate frequencies between 34 and 56 kHz for wideband hydrophones and between 41 kHz and 44 kHz for narrowband hydrophones.
• Echosounders are usually placed around 38 kHz, make sure to allow enough distance with them.

Example of a system with Spread, Catch, Trawl Speed sensors and Speed Explorer, Catch Explorer, HDTE and Door Sounder.

Example of a system with Spread sensors with positioning, Catch sensors, Trawl Explorer and Catch Explorer.
Example of a system for purse seining, with a Seine Explorer and depth Seine sensors.

Bandwidth
Mandatory distance with other sensors
Avoid allocating frequencies between 37 and 39 kHz because this range is generally used by echosounders.
