FX3Uand D225 device connection
Note: 1. The example in the figure is to connect D225 equipment with RS422 to RS232 line, and
also introduces the connection method with communication expansion module
2.Plug the 12V/1A power adapter directly into the power hole of the D225 device, or plug the 12V
power cord connector into the power terminal hole next to the power hole, pay attention to the
positive and negative.
3.The network cable in the example in the picture is connected to the router, and the same LAN as
the computer
Connection instructions: (1) D225 device power cord (12V/1A), (2) D225 device network cable
connected to the router, (3) and (4) connected via RS422 to RS232 cable, the RS422 interface of
the PLC is connected to the D225 device RS232 interface, (5) PLC power cord, (6) If the D225 device
is not connected to the PLC RS422 interface, it can also be connected to the D225 device through
the PLC expansion communication module, and the RS232 expansion communication module is
directly connected to the D225 device through the RS232 line The RS485 expansion communication
module is directly connected to the RS485 port of the D225 device through the RS485 line, (7) the
RS485 port of the D225 device
