ETN21 and barcode reader

4 posts in this topic

Hi there, Actually I'm using an Omron V500 reader in serial to a SCU board. I would like to use it in Ethernet. I have a ETN21 and a Moxa NPORT 5110 Serial-TCP Server. Actually I have a trigger, I enable the reading and I wait in the SCU serial port the message from reader. I want to do the same, but waiting the answer in a ETN21 socket . I would like to understand how it works , if you have suggestions and it there are FB just for reading, keeping opened the socket. Another question is how to simulate from a PC the traffic of Reader ( send TCP packet ) because I have not the reader here and I would like to test program ( i just have the ETN21) Thank you in advance! Regards

Thanks for sharing. But It seems that the platform is not the same as the topic talks about.

Like you said, the barcode scanner you are testing now can decode and scan linear and 2d barcode from any commonly used image format. Then I assume it definitely reads and decodes EAN 128 since it is quite a popular barcode type. And why test it first? Edited by makaveiljojo
