5~10W Long Range Radio Modem FSK Wireless Radio Modem 1200~9600bps
Features:
1)High-speed, stable, compatible and reliable
2)Wide operating voltage: DC9V~36V
Integrated with bust-boost converter ,when input DC 9v~36v voltage,it can work properly without affect the function and performance of radio. Its power supply system support DC9-15V, DC24V and other occasions.
3)Transfer rate support the range of 1200~9600bps
User can modify the transfer rate by computer install the software to achieve optimal communication effect.
4) Variety of communication interfaces coexist:
Radio provide RS-485, RS-232 serial port, users do not need to switch. (user can only use only one interface at a time)
5)Data delay is less than 10ms, you can replace the RS-485 cable systems in a variety of occasions, the upper layer software without changes.
6)Support MODBUS,PPI and other communication protocols to support wireless download PLC program
7)RF power and working frequency can be setup by PC
