for any NMEA sentences received. Any pair of characters
within the NMEA specification are recognized.
The MX500 does process floating numerical formats in
the received sentences.
Although the current version of the NMEA 0183 standard
requires that a checksum be present, the checksum is
not required by the MX500. However, if the checksum is
included in the NMEA sentence, the MX500 will reject any
sentence where the checksum and data do not correlate.
Viewing Input Data
You can view data being sent to the MX500 by other
equipment or loop a MX500 output port back to an un-
used input port to verify if it is outputting data to other
equipment. This is a great tool to use when you are first
interfacing equipment.
