Pripojeni GPS modulu k AIS radaru

[peter tesar]

Zdravim,
ja pouzivam k AIS prijimacu (pripojenom k PC cez RS232) GPS Navilock 
pripojeny cez USB (v podstate cez RS232 cez zabudovany USB-to-RS232 
prevodnik). Vsetko musi byt na rovnakom protokole NMEA (to treba 
nastavit v konfiguracnom programe ku GPS, casto totiz GPS prijimace 
komunikuju prednostne v nejakom proprietarnom protokole, ale zatial 
vsetky co som mal v rukach vedia prepnut aj do NMEA). Musi to byt aj na 
rovnakom bitrate (tusim 38400).
Nerobi to ziadne problemy, ten NMEA protokol je jednoduchy a do praxe 
vyborny.
