MODEL XP15
NMEA 0183 Expander
DESCRIPTION
: The XP15 Expander is an advanced version of its predecessor (XP14)
with an additional output, a bicolor status LED and more short circuit protection on the
outputs. It enables NMEA 0183 talkers to drive multiple listeners . It provides a single
opto-isolated input and four independent differential RS-422 outputs plus a fifth RS-232
output for driving single-ended listeners such as PC’s. Although intended for 4800 baud
operation, it will also operate at 9600 baud.
Many marine instruments, although compliant with the NMEA 0183 specification, do not
provide sufficient drive capability for multiple listeners. To overcome this, the XP15 has
five outputs, each of which can drive multiple listeners if needed. All outputs are isolated
from each other, so that shorting one will not affect the others.
The XP15 can operate on any DC voltage from 10-30 Vdc. A bicolor LED on the unit
flashes green when input data is detected, but will turn red or yellow if a supply current
