DX-28 ACTISENSE NMEA 0183 Dual expander

The DX28 Expander is a 2-channel signal splitter/amplifier for NMEA 0183 data signal distribution. It can be configured as one 1-in x 8-out expander two 1-in x 4-out expanders or an autoswitching expander. The two inputs are completely independent and can operate at the same or different baud rates up to 38 400. The selectable auto-switching feature enables automatic switchover to the AUXILIARY input when signal is lost from the PRIMARY input. A bicolor (green/red) status LED on each input shows data activity and a third LED (yellow) provides “overcurrent” fault indication.
