The MiniPlex-BUF is an advanced NMEA buffer/splitter with one input and seven outputs, designed to seamlessly serve NMEA data from one source to multiple devices.
The offered NMEA signal is amplified to the correct NMEA level so that the connected devices receive a signal that complies with the NMEA standard. Fully isolated inputs and outputs ensure ground loops are eliminated. The outputs are short-circuit-proof, so that one or more short-circuited outputs have no influence on the transport of NMEA data to the other outputs.
The MiniPlex-BUF has a galvanically isolated input with a high-speed optocoupler. The input is able to process signals up to 38400 baud and fully complies with the NMEA standard, so that a reliable signal transmission is still guaranteed with long cables or a high level of interference. The isolation prevents unwanted ground loops between the connected device and the buffer. The buffer can withstand fault voltages up to 1500V.
The MiniPlex-BUF has 7 fully isolated outputs, each with its own opto-coupler and galvanically isolated power supply. As a result, the outputs are completely floating so that they can be connected to any type of input without any problems. Each output automatically adapts to the type of input it is connected to, whether it is single wire or differential. Even a connection to a grounded RS-232 input on a computer is no problem and will not affect the other outputs.
