Four. Product appearance
Five. Module indicator lamp and switch function specification
1. POW/SET;Module working status indication
A.Green light: the module works in the running state. B. red light: the module has the configuration parameters have been written, need to re power up.
2. TXD/RXD:Communication status indication
A.The green light flashes: the communication receives the data B. red light flashes: the module is sending data
C.The green light is always on: DATA+ and DATA- on the communication line RS485 line is connected to the reverse or the connection is broken.
Three Internal upper left corner reset switch
A. When the communication parameters (module address, baud rate, parity bit) do not know or communication parameter misspecification, and can not establish contact module communication, the solution is to reset the communication parameters; we use the clip to hold the reset switch is not open, 5 seconds after the [POW/SET] module of the red indicator lights, release the reset switch, the communication the parameters have been reset, as long as the power supply module after the restart time, the communication parameters of the module has been reset.
B. Communication parameters after reset: Address: 1, baud rate: 9600bps, parity: No.
