PufangTech`s SCADA radio modems have air data rates of 19200bps in 25KHz channel spacing and 9600bps in 12.5KHz. For master station of SCADA system, RS232 interface port is usually standard, while RS485 is often adopted by slave station.
Our SCADA Radio Modem has short Transmit-to-Receive turn around time that enables fast polling in your wireless telemetry system. It is easy to use and implement transparent data transmission.
RS232 or RS485 serial inputs and outputs are supported by PufangTech`s SCADA radio modems. The serial baud rates can be changed from 1200bps to 115200bps with a Windows based program on PC.
