how to compare serial numbers and store them in differnt location

[sandy1]

hi,

I am developing test software using labview, which read/writes various data from DUT. I have to test 200 of them, and also i have add serail number to it.

 My question is,

• How can i register all 200 numbers.
• if i retest the dut, my program should recoginse the serial number and should dispaly that, this DUT has been used before.
• how can i log all serail numbers in sequence, and there results in log file?

First, how are you communicating with the DUT?  Can you ask it for its SN?  If it hasn't been set, how will the DUT respond?  Do you know when you are retesting or do you expect the software to determine that based on the response received from the DUT? 

What do mean by "register all 200 numbers"?

Hi,

I am using bar code reader to store srial number, into perticular location in DUT, so i can read/write back from DUT using dll.

When i scan the barcode , my labview program should compare serial number (if we are retesting the DUT), if it is used before, it should retest it and it should go back to  same location in log file  where i have stored details of DUT.

Hi Sandy1,

what have you done so far? Which format has your log file? Do you use a database? Can you already scan the barcode?

Are you using a barcode reader that acts like a keyboard? 

You say "if it has been used before" -- does that mean you are comparing to some information stored somewhere?

If you have any code, please post it.
