I have successfully downloaded the HMI program into NB7W-TW00B, but there is no display on the HMI because the communication indicator which is connected by the RS232 cable doesn't light up.
I have verified the wiring and pinout of the RS232 communication cable. What else can be done to troubleshoot this issue?
