        As an Amateur Radio operator I needed an interface device to connect my serial devices to the computer. There are many USB/Serial adpators on the market. The Keyspan USB/Serial adpator has proven time & again to be the hands down favorite due to its reliability, quality and performance. You will not regret this purchase, especially if your looking to interface your serial devices to the computer.

                I was having a lot of problem with a low quality adapter. Through troubleshooting I realize the problem was the adapter and I received a recommendation to get the Keyspan USA19HS. As soon that I connected it the problem of transmitting data for a software upgrade went away immediately. Great product and easy to use with Windows 7. I recommended!

                  I have one in use on a computer running 24/7.
                  Each time I need to go out in the field and program another unit, I had to disconnect it and bring it along. Now I keep one in my go kit.
                  The adapter has never failed me and I have read of the knock offs out there that do not always perform.
                  Well pleased and although more expensive than others, you get what you pay for.

                                    The adapter was very useful and the performance was excellent. I had used several others but this one worked just after installation and it was fast too.

                                              I use this adapter for programming many different devices. I have used multiple other USB to serial adapters that haven't communicated consistantly. This is the first adapter that works everytime on every different device I try to communicate with. It worked so well our programming group standardized on them and I purchased one for everyone on my team.
