Buffer for NMEA Buffer Box for NMEA Buffer 1 in 4 Out Marine Serial Line Splitter Isolating Buffer Converter Interface for 24V Circuit Systems

Input Signal ---- 4 input ports, supports up to 115,200bps, selectable auto manual switching by external switch, selectable primary secondary input by external switch. Professional manufactured, exquisite workmanship with unique design, ensure stable performance and high reliability.
Safe Operation ---- The marine serial line splitter supports over voltage protection, over current and surge voltage protection, reverse input and over current protection. There are wiring instructions at the wiring area to prevent wiring errors, and pluggable screw terminals for quick and easy installation and diagnostics.
Design ---- Galvanic isolation of Each output group, input, main circuits and power, selectable RS232, RS422, TTL on 8 output port. All components are rigorously inspected and meet the strictest quality standards for stable performance and long service life.
Durable Material ---- Isolating Buffer for NMEA Buffer Box is made of aluminium alloy shell, anti rust treatment, will not be oxidized and corroded by seawater or air, long term durability. In use, material is not prone to rust, and fading problems, which makes it can be used for a long time without frequent replacement.
Note ---- The primary function of a marine serial line distributor is to connect a single serial data line to multiple devices or systems. When there is only one serial data source, the serial line distributor can distribute the data stream to several different components or devices, enabling data interaction between multiple devices.
