Scanner Beeping

For a very long time users that are involved in operations have requested that the scanners beep differently when there’s some sort of problem: incorrect box, unknown box, incorrect order, incorrect carrier, etc. And for a very long time we’ve been trying to figure this out… to no avail.

A couple of weeks ago I had the chance to talk with John Markhorst from DVFG who showed me how he made his scanners beep. After realizing that the technology used to power the scanners that we use at Komet was pretty much the same, John pointed me in the right direction on how to make this work. Now I’m excited to share with the Komet users that we’re able to make the scanners beep.

Most people won’t get excited by this or even realize the huge impact that this very simple thing has on the day to day operations within the warehouse. One of our customers expressed that someone that works in the cooler “almost cried” when he heard about the news. It’s a very big deal and it’s a very positive change that will make the warehouse operations more efficient. 

I’m quoting John on his response after I let him know that it worked:

“Old School” RULES!!!!    K.I.S.S.

For those of you that are curious on the tech side this is all that it took:


One line of code that will make a HUGE difference. Once again I want to publicly thank John Markhorst for his contribution and help on this: he deserves all the credit. We were searching for the solution in outer space and the answer was in our backyard.
