I have tested several of these IC"s both new and suspect and I can not get a pass on any 74ls193,194 or 670"s. Is something buggy in the software ?

So I checked the data sheets and a 192 is functionally equivalent to a 193 and the software found it as a 192. The test for a 193 is different than the 192 though so I don"t know what"s going on there.

Still doesn"t explain why the programmer can"t find nor test a 194 or 670 although they are listed.

Any ideas ?

about 193,194 please download.
about 670, maybe VP-190 cannot support it because its hardware.

Please download what ? I don"t suppose there is an actual accurate list available from the maker of this device that says exactly what it will do and will not do ? I"m getting frustrated with the uncertainty.

I have attempted to test 74ls191,193,194,393,670 and 109"s that I  know are good but they all test bad on the VP-190.

Is this a software problem or is the 190 incapable of testing these  devices. If I knew the answer I could either attempt a fix of the      vectors or move on to a different product.

If this forum is monitored by Wellon staff then it would be nice to    hear from one of you on this. And please give me a coherent answer  not just "download the new soft."

OK I"ll download the new soft. I have recently updated so which version has the corrections I am looking for ?

If you are not a member of the support staff then I apologize in advance and thank you for your help. If your a Wellon employee then how do you not know what the device is capable of ? Does anyone at Wellon have this info that they could pass on ?  It would be really helpful.

Verson 4.6.0 is the new software verson.

For TTL testing, originally, it"s not the function of VP-190. Because some customers required this function for 190, we add this function in 190. But because of the limitation of the hardware, 190 can"t support some chips that higher-level programers support. We will soon seperate those chips and sorry for the inconvenient.
