Appendix D:
Verifying the NMEA 0183
Message
Verify the message supplied by the NMEA 0183 talker by
connecting its output to a laptop using an RS422-to-USB
adapter cable and viewing its data stream using PuTTY,
HyperTerminal, or other terminal emulator.
Follow these instructions to verify the message.
Note: These example instructions assume you will be using
PuTTY.
1. Using an RS422-to-USB adapter, connect the NMEA
0183 talker to the adapter’s RS422 input. Then
connect the adapter to the laptop’s USB port.

type, and baud rate.
