Installation Warnings

All warnings and notices must be followed to ensure the correct operation of the PRO-NBF-1. Incorrect installation may invalidate the guarantee.
It is highly recommended that all of the installation instructions be read before commencing the installation. There are important warnings and notes throughout the manual that should be considered before the installation is attempted.

Warning 1: Accuracy
The Actisense PRO-NBF-1 is designed to accurately transfer data from the input to its outputs. No data integrity checking is performed by the PRO-NBF-1. Any incomplete, inaccurate, or corrupt data received on the PRO-NBF-1 input will be duplicated to the PRO-NBF-1 outputs. The accuracy of the data is dependant on the NMEA Talker or other source device that generated the data.

Warning 2: Installation and Operation
This product must be installed and operated in accordance with the instructions provided. Failure to do so could result in personal injury, damage to your boat, and/or poor product performance.

Warning 3: Installation Code of Practice
When wiring the power supply to the PRO-NBF-1 ensure the isolation switch is off. Wiring the PRO-NBF-1 while the connection is live may damage the PRO- NBF-1 and is in breach of the guarantee. Any connection to a battery or power supply must meet the mandatory essential safety requirements that may be imposed by local regulatory agencies.
All wiring should be in accordance with the requirements of the NMEA 0400 installation specification.

Warning 4: Mounting Requirements
Select a flat location to mount the PRO-NBF-1. Mounting on a contoured surface may cause damage to the case.
Do not mount the PRO-NBF-1 while the device is powered.
Do not mount the PRO-NBF-1 while the cable harness is connected.
Note that the terminals are pluggable for easy disconnection when mounting or removing the PRO-NBF-1.

Mounting the PRO-NBF-1

Bulkhead Mounting Method:
Actisense recommends the PRO-NBF-1 be installed using DIN rail for the most secure installation. However, the PRO-NBF-1 can be secured to a bulkhead using the four screw holes on either side of the PRO-NBF-1.

DIN Rail Mounting Method:
Install the DIN rail in the desired location.
Attach the PRO-NBF-1 to the DIN rail as shown in the diagrams below.
Ensure the PRO-NBF-1 sits flush against the DIN rail.

Terminals

The PRO-NBF-1 comes with 2-way and 3-way screw connectors. Screwless terminals are available as an accessory. PRO-NBF-1 connectors are pluggable, meaning they can be easily removed for quick and simple wire installation without the need to unmount the PRO-NBF-1 from its installed location.

Screw Connector

Screwless Connector (Supplied as an accessory)

Open the clamp inside the screwless connector by pressing down on the orange button with a small (2mm) flat-headed screwdriver. This will allow the wire to be inserted. For best connections do not twist the wire strands.
Release the orange button to lower the clamp onto the wire strands for a secure termination.

Connecting Power to the PRO-NBF-1

• The PRO-NBF-1 requires a power source providing between 10 and 35 Volts DC.
• The PRO-NBF-1 ‘+ ’ Terminal should be connected to the vessel power supply ‘ + ’ Terminal with the correctly rated fuse (in accordance with NMEA 0400 Standard)
• The PRO-NBF-1 Negative ‘-’ Terminal should be connected to the vessel’s DC Ground Plate.
• The PRO-NBF-1 should only be used with standard negative ground DC systems.

NMEA 0183 Listener and Talker Designations

The NMEA has updated the NMEA 0183 specification to ensure a consistent naming convention is used for labeling ports. The designation follows the same rules as used for Rx and Tx labeling but uses Talker and Listener instead.
The input / receiving (Rx) port will be labeled as a ‘Listener’ port.
The output/transmitting (Tx) port will be labeled as a ‘Talker’ port.
When a port is labeled ‘Listener’ it is an input and when it is labeled ‘Talker’ it is an output.

Connecting to the PRO-NBF-1 Listener Port (INPUT)

The input to the PRO-NBF-1 is labeled ‘Listener’ and this is where the NMEA Talker should be connected:

• Connect the PRO-NBF-1 Listener A/+ to the positive data line of the NMEA Talker. When connecting RS232 or NMEA 0183 version 1 Talkers, this will be the Tx/data out of the Talker.
• Connect the PRO-NBF-1 Listener B/- to the negative data line of the NMEA Talker. When connecting RS232 or NMEA 0183 version 1 Talkers, this will be the ground / common of the Talker. Always check the manual for the correct wiring.
  Note: Only one NMEA Talker can be connected to the PRO-NBF-1 Listener (Input) ports.
  Note: The NMEA Listener (Input) ports are fully isolated and are compatible with all versions of NMEA 0183 and with RS422, RS232, and RS485 voltage levels.

Connecting to the PRO-NBF-1 Talker Port (OUTPUT)

The output to the PRO-NBF-1 is labeled ‘Talker’ and this is where the NMEA Listener should be connected:

• Connect the PRO-NBF-1 Talker A/+ to the positive data line of the NMEA Listener. When connecting RS232 or NMEA 0183 version 1 Listener, this will be the Rx / Data In of the Listener.
• Connect the PRO-NBF-1 Talker B/- to the negative data line of the NMEA Listener. When connecting RS232 or NMEA 0183 version 1 Talkers, this will be the ground / common of the Listener.
  Care should be taken when creating this connection. It is only possible to wire B/- into GND thanks to Actisense ISODrive technology providing protection. Consult the relevant User Manual if not using Actisense Products for wiring instructions.

Connecting an RS232 Device (PC) as a Talker

A PC can be connected the same way as an RS232 type NMEA Talker.

• Connect the NBF-3 Listener A/+ to the Tx pin of the RS232 connector. (PIN 3)
• Connect the NBF-3 Listener B/- to the Ground pin of the RS232 connector. (PIN 5)

Connecting an RS232 Device (PC) as a Listener

A PC can be connected the same way as an RS232 type NMEA Listener.

• Connect the PRO-NBF-1 Listener A/+ to the Tx pin of the RS232 connector. (PIN 2)
• Connect the PRO-NBF-1 Listener B/- to the Ground pin of the RS232 connector. (PIN 5)

Troubleshooting Guide

The first level PRO-NBF-1 diagnostics/fault finding can be performed by observing the LED behavior. The normal behavior of the PRO-NBF-1 LEDs is described below. If the LEDs are not behaving as expected, this will indicate a fault in either the device connected to the PRO-NBF-1, the wiring/connections, or the PRO-NBF-1 itself.

Power (Blue ‘PWR’) LED
Solid blue to indicate the presence of power.| • Ensure that the power terminal plug is correctly located and seated.
• Ensure that the wires are securely connected to the plug.
• Ensure that positive power and ground wires have been connected with the correct polarity.
• Ensure that any external power fuse has not blown and that the external power isolation switch is closed.
• Ensure that the power supply meets the Voltage and Current requirements as defined in the Specifications
Listener (Green ‘IN’) LEDs
Flashes on receipt of any data|

• Ensure that the PRO-NBF-1 has power, refer to “Power (Blue ‘PWR’) LED” above.
• Ensure that the (NMEA Talker) device connected to this input is powered and is configured to output data.
•Ensure that the plug is correctly located and the wires are securely connected to the plug, with the correct polarity.
• Ensure that two data wires are connected to the PRO-NBF-1 Listener terminals. If the (NMEA Talker) device does not have a ‘negative’ data connection/wire, connect its ground to the ‘B/-’ on the PRO-NBF-1 Listener terminal instead.

Talker (Amber ‘OUT’) LEDs
Flashes on transmit of data| • Ensure that the PRO-NBF-1 has power, refer to “Power (Blue ‘PWR’) LED” above.
• Ensure that the plug is correctly located and the wires are securely connected to the plug, with the correct polarity.
• Ensure that the corresponding Green (Data IN) LED is lit to indicate that data is being sent to the PRO-NBF-1.
• For PC Connections, Actisense NMEA Reader can be used to determine if there is any data on the output.

Technical Support and the Returns Procedure
All installation instructions and any warnings contained in this manual must be followed before contacting Actisense technical support. If the troubleshooting guide did not help resolve the problem and an error persists, please contact Actisense Technical Support to help trace the issue before considering the return of the product. If the Actisense support engineer concludes that the PRO-NBF-1 unit should be returned to Actisense, a ‘Return Merchandise Authorisation (RMA) number will be issued by the support engineer.
The RMA number must be clearly visible on both the external packaging and any documentation returned with the product. Any returns sent without an RMA Number will incur a delay in being processed and a possible charge. Any cables originally supplied with the product are to be included in the returned box.
