MP2x8i NMEA Buffer

Type approved NMEA buffer.

By combining the wishes of both technicians and clients we developed a user-friendly and reliable NMEA Buffer.
The MP2x8i NMEA Buffer has been designed to distribute NMEA-0183 or other RS422 signals from one transmitter up to 8 listeners. In dual buffer mode it can even operate as two independent buffers with 1 input and 4 outputs.
