and format. If a valid baud rate and format is not found, the MVP will change its baud rate and try again. If
you do not have the MVP connected to a GPS, set the Port 2 Receive field to “Disabled.”
Note: If the MVP includes the “Chelton Interface Option” and Port 2 Tx Format (Out) is set to “Chelton
Data,” Port 2 Receive (GPS In) will only auto detect for GPS signals at 9600 baud.
“Port 2 Receive Status”: When the Port 2 Receive field is
set to “Auto Detect Enabled” the Port 2 Receive Status field
will show one of the following:
“Trying 9600”: The MVP is looking for a GPS
signal at 9600 baud.
“Trying 4800”: The MVP is looking for a GPS
signal at 4800 baud.
“OK: Moving Map 9600”: The MVP has found the
moving map format at 9600 baud.
“OK: NEMA 4800”: The MVP has found the
NEMA format at 4800 baud.
“OK: NEMA 9600”: The MVP has found the NEMA format at 9600 baud.
Note: If the MVP cannot find a valid GPS signal, the Port 2 Receive Status field will switch (every six
seconds) between “Trying 9600” and “Trying 4800.” If the MVP cannot find a valid GPS signal or the
MVP is not connected to a GPS, the Port 2 Receive field should be set to “Disabled.” The Tx port
will not transmit when the Receive Port is “Trying.”
“Port 2 TX Format (Out)”: This field sets the format of the transmitted signal on Port 2 output. The
following selections are available:
“Disabled”: Disables the output.
“Old Shadin”: Outputs the older Shadin fuel flow data to a GPS unit. Works with many older
ARNAV, King and some newer Garmin GPS units.
“Shadin”: Outputs the Shadin fuel flow sentence to a GPS unit. Works with Garmin and many other
GPS units.
“Modified Shadin”: Outputs the Shadin fuel/airdata sentence to a GPS unit. Works with many UPS
GPS units and some Garmin units.
“Chelton Data”: This selection is only available for units ordered with the Chelton Interface Option. If
Chelton Data is selected, Port 2 input and output will only operate at 9600 baud.
