Collection: NMEA 0183 Buffers/Expanders

An NMEA 0183 buffer is a device or component used in marine electronics and navigation systems to manage and distribute NMEA 0183 data. NMEA 0183 is an older, standard protocol used in marine electronics for communication between various devices, such as GPS receivers, depth sounders, autopilots, and other navigation and communication equipment.

The NMEA 0183 protocol uses a serial communication format, and data is transmitted in the form of ASCII characters over a serial connection (typically RS-422 or RS-232). However, in a complex marine electronics setup where multiple devices need to communicate with each other, there might be issues such as signal degradation, data collisions, or electrical noise under which a NMEA 0183 Buffer can be of great help.
