Waveshare UART TO ETH User Manual

RS485 TO ETH ( B)
than 1 second, the module will restart with the default
IP of 192.168.1.254, static IP mode, 255.255.255.0
gateway, and 192.168.1.1 gateway. You can also set
your own reset parameters with the param.txt
configuration file.
RUN
OUT
Working indicator, the chip works properly, and will
output a square wave with a period of 2 seconds. You
can connect a 4.7K resistor and then connect the LED
to the ground and the LED is on indicating the chip
has been working.
EN
OUT
The 485 transmit controller, normally 0, becomes 1
when the module sends data to the serial port. It can
be connected directly to the TXD_EN pin of the
MAX485 chip.
RTS
OUT
Hardware flow control output. After the flow control is
set to CTS/RTS, DTR/DSR, RTS=0 normally, if RTS=1, it
means the module can't receive data and the user
MCU should stop sending data to the module.
CTS
IN
Hardware flow control input, when the chip is
configured for CTS/RTS, DSR/DTR serial mode, only
when CTS=0, the chip serial port will output data to
the outside.
GND
Ground
Ground
LINK2
OUT
When it is 0, it indicates that the module RJ45 network
cable is connected.
ACT
OUT
Data indicator. When it is 0, it indicates that there is
data being sent and received at the serial port. But
when there is data, this pin will jump between 0 and 1.
ACT=1, which cannot be used as a flag for no data
communication.
LINK
OUT
TCP connection indicator. When it is 0, the module has
established TCP/UDP connection with the network
server, and the module can send and receive data
normally. If the network cable is unplugged at this
