Old HMI NT21-ST121-E

[504bloke 1]

Ok, have an old HMI and need to load the software from it

Purchased a USB to RS232 C200HS-CN220-Eu from mark at placable.com

Have tried every different com setting and put the HMI in transmit mode but the laptop will not communicate (NT Support tool) with the HMI

Screen Shots attached

Is there something I am missing ??

You'll need to check to see if COM3 is being used by another device.

It shouldn't be - VM on a Mac and plug it in and use it for omron

How would I check to see if something else is using it ?

In your base OS, goto Devices and see which COM ports are occupied.
