Communication Ports

DVP-ES2/EX2/SA2/SE/SX2 offers 3 communication ports (COM1~COM3), and DVP-SS2/EC5 offers 2
COM ports (COM1~COM2). COM ports of the above models support DELTA Q-link communication
format on HMI. Refresh rate of HMI can be increased by this function.
COM1: RS-232 communication port. COM1 can be used as master or slave and is the major COM port
for PLC programming. (It is not applicable to DVP-SE.)
COM2: RS-485 communication port. COM2 can be used as master or slave. ES2-C V40 or later does
NOT support 600 bmp.
COM3 (ES2/EX2/SA2/SE): RS-485 communication port. COM3 can be used as master or slave. (For
COM3 (SX2): Conversion from the USB port to RS-232 port. COM3 can be used as slave only.
The 3 COM ports on the models mentioned above support Modbus ASCII or RTU
communication format.
USB (COM1) (SE): USB communication port. It only can be used as a slave. The communication
mode and format can not be modified.
