Omron K3HB RS232 Communication

[ReadingA]

Morning All

I'm trying to alter an old program that was reading a Druck 282 DPI to read an Omron K3HB DPI over RS232. I have the coms string for the Omron (02H 01 00 0 0 0101 C0 0002 00 0001 03H), but it does not seem to be working. I've attached a screen grab of the code I'm working with.

Any help would be appreciated.

Hi Andy, 

Have you tried using this VI to test for a response from the Omron?

Are you able to find the Omron as a VISA resource?

Let me know how you get on with these examples.

Hi Tim

I've run both programs. The VI for getting a response gave nothing, I was getting 0 bytes at the port. The one for VISA resources found nothing, generating an error at the VISA find resource node.

I guess from that the Omron is not communicating with VISA?

Better post the vi instead of a png of the BD 😉

Seems that you need to send the hex values.

Have you set the display style of your string input to hex?

If not, do so 😉  by rigth click the string control and set it to hex display

Hi Andy, 

Have you tried following these steps for configuring a serial device?
