• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

I just acquired a KPC-3+ and am looking to start setting it up. Does anyone have a recommendation of a serial to usb converter that will work well this this system? I apologize if this has been asked, it is hard to search "usb" on the forum due to the commonality of the term. Thanks.

Get an RS-232 to USB converter that uses the FTDI chip. You will also find converters using the Prolific chip, but they can be a bit of a problem. The Prolific chip has been cloned and the Prolific drivers don't always work properly with the cloned chips.

You'll also need to convert from the DB-9 connector that most RS-232 to USB converters have to a DB-25 connector for the KPC3+. There are adapters and adapter cables available to do that, but they are getting hard to find. Check with a big online computer cable retailer like Cables2Go or Monoprice.

I prefer the Edgeport series from Digi. The driver software can be configured to make the device the same COM port number irregardless of which USB port it is plugged into. If you have a GPS connected to the devices with the Prolific chipset, Windows will usually enumerate it as a serial mouse and make the cursor jump madly around the screen. The Digi models do not do this.

Yes, Digi makes very good RS-232 to USB converters. A little price, though.

The Microsoft COMdisable tool will fix this with some versions of Windows. See the following:

Overview of the COMDisable Tool

I believe Windows 7 requires a Windows Registry fix to address this.

Yes, the Digi units are a little pricey but they seem to be one of the better options.

I've had mixed results with COMDisable. Registry is one way or it can be done through Group Policy too. Neither method is a trivial task and sometimes takes more than one attempt to get it right. The agency I work for has fought with this since Windows 7 came out and MDTs were upgraded to Win 7.

What about the good ol' Iomega GUC232A? You can still find them on amazon and microcenter-type sites.

I haven't found anything it won't work with to date.

We've been using the Quatech SSU-100's on XP for a couple of years. No issues even with Mother's old programs running in a DOS window. Bought them at Provantage.
