Page 14: Output Formats
OUTPUT FORMATS If the optional pressure sensor is fitted and enabled then the only data format that supports this is the Valeport NMEA format. A number of other formats have been implemented to provide compatibility with existing systems. VALEPORT NMEA $PRVAT, xx.xxx,M, xxxx.xxx, dBar*hh<CR><LF>... - Page 15 The serial output will be in the following format: Rxx.xx<cr><lf> where xx.xx can range from 0.10 to 99.99. If no echo was received the output will be R99.99E<cr><lf>. Example: R00.13 R00.12 R00.12 R00.12 R00.12 R00.12 R00.12 R00.12 VA500 Altimeter Manual Page 15 0430831e_VA500_Altimeter_Manual...
