DVP-ES2/EX2/SA2/SE/SX2 offers 3 communication ports (COM1~COM3), and DVP-SS2 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.

COM3 (ES2/EX2/SA2/SE): RS-485 communication port. COM3 can be used as master or slave. (For
