whether the serial server and the upper computer software to establish
a communication link.
1) The indicator light is green when the network port sends data to the
serial port. The flashing time is 1 second longer than the actual
communication time, making it easier to find short data communication.
2) When the serial port sends data to the network port, the indicator light is
both blue and green. Since blue is brighter, seeing blue indicates that
there is a serial port returning data to the network port. This can
determine whether the device has a response to the command of the
upper computer, if there is no corresponding indicates that the serial
port baud rate is wrong or the serial port is not connected well.
Use indicator light to debug communication method:
1) If the Link light is not green, the network cable is not well connected. Please
check the network cable.
2) If the Link lamp is not blue (only consider the TCP operating mode), then the
upper computer software does not establish a connection with the serial port
server. Please consider whether the IP address is configured in the same
network segment.
3) If the Active light is green, data is sent from a network port but not returned
from a serial device. Please check whether the baud rate is configured well
and whether the RS485 plus or minus is reversed.
4) Installation method: the equipment shell is equipped with 35mm standard
guide rail. When there is a guide rail, the equipment can be directly installed
into the guide rail.
