RTS-03 Usb to Serial Adapter
RTS-03 USB to serial adapter

Price: $23.00

Product Code: RTS-03

The RTS-03 Adapter works with RT Systems Version 4 software and the original RT Systems serial cables for radio programming.

RTS-03 adapter forms an RS-232 comport that can be used by other applications. This USB to serial adapter forms a port that allows data to flow properly between decives without interference from its electronics.

Use it whenever the cable from the radio manufacturer comes with a DB-9 connection (packet cables, firmware upgrade cables, CAT cables, etc.).

This adapter WORKS... and you have RT Systems support to help you should you need it.

3 of 5 Just worked; needs better packaging design May 17, 2020
Reviewer: greg forrest from pleasanton, CA United States  
I own four USB/Serial converters from RTS.  None of the cables or drivers have ever failed.  However, the fact that the conversion device is integral to the USB plug is poor design.  This often prevents other devices from using an adjacent port, but worse, it can get snapped off too easily.  I always have to add a 1-ft. flexible jumper to these.   The best design I have seen for these:  electronics contained in a rugged, sealed/molded plastic "clump" between two flexible cables.   Perfect example:  

Also - after using Amazon for so long (could not in this case), I now appreciate how fast Amazon and their suppliers must get the package in the shippers hands (not just get the shipping label).  Ordering directly from any supplier remains a crap shoot; RT was OK but this might have been delayed a bit.  

But I still won't buy any other brand yet..including Gigaware/RS as they have hosed me in the past  :)

1 of 5 RTS-03, order 104620 April 21, 2020
Reviewer: AGERanger from Henderson, NV United States  
I bought this cable to interface with the CAT Jack , a DB-9 Male jack, on the back of a Yaesu FT-450D. The RTS-03 shows up if you do a search on the radio.  This cable comes with a DB-9 Male.  A straight serial cable comes with 2 DB-9 Female connectors. Both of my old computers have serial ports with DB-9 Male connectors. Are you getting the picture? If I had the serial cable, I wouldn't need the RTS-03 either. Sure, a DB-9 female to DB-9 female adapter is only $3 at the local Fry's, but I still have to go get it to use the RTS-03.


That would have been the USB-63 cable.  Right gender and complete interface without having to add another cable.

5 of 5 RTS-03 / USB to RS232 Cable January 23, 2020
Reviewer: John W. from West Melbourne, FL United States  
Works like a charm. Windows-10 Installed the drivers without any user intervention. A quality product that I fully recommend if you require an RS232 Port.
