Noland SX14 NMEA 0183 Expander 

The SX14 Expander is an advanced version of its predecessor (XP15) with very low power consumption, hi-speed operation to 38,400 baud, and outputs that withstand indefinite short circuits. It provides a single opto-isolated input and four independent differential (RS-422) outputs which are also compatible with RS-232 listeners.

Many marine instruments, although compliant with the NMEA 0183 specification, do not provide sufficient drive capability for multiple listeners. To overcome this, the SX14 has four outputs, each of which can drive multiple listeners, both RS-422 and/or RS-232, as needed. All outputs are isolated from each other, so that shorting one will not affect the others. A green data LED and a yellow fault LED indicate the unit is operating and connected properly.
