ACTISENSE PRO-NBF-1 NMEA0183 Buffer

The Actisense PRO-NBF-1 NMEA0183 Buffer can connect one NMEA0183 output (Talker) with up to 6 NMEA0183 inputs (Listener). The NMEA0183 data is isolated and buffered and distributed to the inputs with identically amplified data streams. Buffering ensures that each receiver receives the data at the required voltage rate, which ensures consistent data quality.

The NMEA0183 output device, as well as the NMEA0183 input devices, are optimally protected thanks to the insulation at the inputs and outputs. Helpful LEDs also indicate the status of the power supply, input and output.

The NMEA buffer features ISO-Drive™ technology at the outputs and OPTO insulation at the input, allowing you to connect the NMEA 0183 buffer.
Housing is made of stainless steel and makes the device robust and resistant, thereby increasing its longevity. The metal housing also acts as RF shielding, making the device ideal for professional use.

Installation
For quick and easy installation, the PRO-NBF-1 has two-piece connectors that allow the use of screw terminals, as well as a DIN rail mounting system (DIN rail not included). The device can also be mounted directly on a bulkhead.

Features

• 1x opto-isolated input
• 6x ISO-Drive™ outputs
• Outputs automatically adapt to the baud rate of the input
• Compatible with RS-232, RS-422 and RS-485 receivers
