# AIS Device Type definition
# ais_fa30_rr (Furuno FA-30 AIS ship presence)
# Furuno FA-30 AIS receiver outputting standard !AIVDO, !AIVDM, and proprietary $PFEC strings,
# prepended with a binary character.
# $PFEC strings are for internal data communication between the monitor unit and UAIS transponder.
# YYYY-MM-DDTHH:MM:SS.SSSSSSZ !AIVDX,n,s,,C,XXXXX,0*cc
# YYYY-MM-DDTHH:MM:SS.SSSSSSZ = time stamp
# AIVDX = AIVDM: data from another vessel, AIVDO: data from our own vessel
# n = number of sentences
# s = sentence number
# C = AIS channel (A or B)
# XXXXX = encoded AIS data; each ASCII character corresponds to 6 binary bits
# 0* = end of AIS data marker
# cc = checksum
