Digital radio provides two-way wireless data transmission transparent channel, the radio is generally the standard RS232 interface, support 300 ~ 38400BPS rate, you can set the length of parity, and asynchronous data formats.
First, the radio parameter settings
New use of radio, only to set the transceiver frequency, transmit power and data rate form can be.
1, Receive frequency, transmit frequency
2, Transmission power
3, The serial port rate, format
Second, the radio station with PLC, RTU connection
Digital radio supports transparent mode (only RXD, TXD, GND three lines) and hardware flow control (with RXD, TXD, GND, with RTS, CTS, etc.).
1, Transparent connection
2, Hardware flow control
Third, the status indicator
Digital radio has PWR, DCD, TXD, RXD four status lights.
1, PWR: continuous light - power is applied to radio equipment, there is no failure is detected.
Fast flash (5 times per second) --- fault indication.
1 flash every 5 seconds --- the radio in sleep mode.
2, DCD: Flash --- indicates the air pulse radio receiver data frame.
--- Indicates a continuous light from another radio device is a radio transmitter to receive a continuous data signal.
3, TXD: Data interface connector on the EIA-232 signal is being received. The radio PIN2 pin serial data received and sent the air.
4, RXD: data interface connector on the EIA-232 signals being sent. The radio air data received and sent to the serial port PIN3 feet.
