I have a problem connecting to omron hmi nt21.
I would like to take backup. I use a serial converter rs232 usb to connect to omron hmi. The fault is: time out error. Number port is set by me OK.
I always set transmit mode in HMI opction.
Can anyone help me.
Hi,
You can check the below link. You required two cable. First USB to Serial and from that serial cable to HMI.
