USR-LG206-P # RS-232/485-LoRa konverter modem/ipari vezeték nélküli adatkommunikáció/3500 méter átviteli táv, USR IOT
Úgy tekintsen erre az eszközre, mint „egy virtuális soros vezetékre a levegőben”, amely az összes távoli berendezését összekapcsolja egy központi számítógéppel. Teljesen átlátható, protokolltól független átjáróként is alkalmazható, használható AMR-hez, SCADA-hoz, általános távoli megfigyeléshez, vezérlő és adatcserélő alkalmazásokhoz.
- Az USR-LG206-P egy fél-duplex LoRa - soros konverter pont-pont protokollal.
- Két soros készülék között pont-pont átvitelt valósít meg.
- Két USR-LG206-P konverter összeköt két soros RS-232 vagy RS-485 portos készüléket bámilyen adatátviteli protokollal.
- Pont - pont protokoll és fix pontos átviteli mód.
- Nagy kommunikációs távolság, interferencia mentes átvitel, nagy ézékenység és air waking up.
- RS-232 vagy RS-485 port EMC védelemmel.
