NX-100 NMEA 0183 Expander

The NX-100 0183 Expander allows multiple listeners to be connected to a single talker. The NX-100 takes either a single-ended RS-232 or a differential RS-422 input signal. It conditions and buffers the input signal to provide three single-ended RS-232 outputs and one differential RS-422 output. It also provides up to 2kV_RMS input-to-output-to-power isolation using optical and transformer technology.

Features:

2000 volts full galvanic isolation between inputs, outputs and power supply.
1 NMEA 0183 / RS-232 input; 1 NMEA 0183 / RS-422 input.
3 NMEA 0183 /RS-232 outputs; 1 NMEA 0183 / RS-422 output.
Wide operating voltage range of 9 to 24 volts DC.
Transient protection on all inputs and outputs.
Fully potted electronics in flame retardant ABS plastic case (UL94V-0) with mounting flanges.
Thermoplastic (UL94V-0) terminal blocks with tin plated brass screws and terminals accepts 24 to 14 AWG.
Buffers and Converts NMEA 0183 signals.
