The BUF-2B provides six independent outputs from any standard NMEA 0183 source. Four outputs are set at the NMEA standard RS-422 signal level.  Two outputs are jumper selectable to either RS-422 or RS-232 for interface to a standard computer serial port.    Pluggable connectors are used for power input, NMEA input, and each NMEA output for ease of installation and troubleshooting.  LEDs are provided to indicate power input and NMEA input.
