Troubleshooting Guide
First level PRO-NBF-1 diagnostics / fault nding 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.
Name of LED and it’s behaviour If LED does not light
Power (Blue ‘PWR’) LED
Solid blue to indicate 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 dened in the Specications
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 congured 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.
