Communicates Successfully Every Time

I have hundreds of clients who have equipment with which I occasionally I have to communicate. I use an Apple laptop with the latest OS. Because the client's devices use only PC Windows, I use Parallels to convert to the Windows platform. Then I use the Keyspan serial adapter and a special modem to get the signal onto the phone lines. The Keyspan works every time.
I've been using this USB to serial adaptor for close to 5 years, and I've used others as well, and they're supposed to be compatible.... Don't hold your breath! This is the one that will work with almost any OS and/or software! I am a 35 year alarm technician and also work with other tech as well. Save your time this is the one for you! In my field, we still are way behind the time as most of the modems still used for downloading and programming systems are at least 35 years old as well (Hayes Smartmodem) Which run around 300-1200 baud.
I bought this product so I could download info from the internet to my car diagnostic device. I looked at a lot of them but only Tripp Lite 19HS fit the bill. When I received it I plugged right to my computer and it did the job.
I have used this product for over 8 years. They are the only ones that will always work no matter what platform you are on. Other usb-serial adapter are hit or miss as to functionality on different computers and system. This is the only one that I have found that the hardware and software are from the same people. This is the only ones that I would and do recommend.
A lot of legacy and even current AV equipment still uses serial cable communication. I have a MacBook Pro running Yosemite, with Windows 8.1 running in Parallels. MOST of the AV configuration software is Windows only. This device allows my Virtual Windows PC to talk to an external serial device with this adaptor as if it were all native on it's own machine. Fantastic!
I've used this for years to allow older serial based equipment to work with newer hardware and it's been perfect. Currently using it with a Mutoh SC-650 as it was easier than finding a laptop with a DB9 port. I'd have no hessitation is buying another as and when the situation requires it. Recently went to set-up a mac book to cut graphics and was surprised to find current mac support on such an old adapter as well. Nice that it's not been abandoned.
I have been using this with a vinyl cutting plotter and when it works, it is flawless. BUT the problem lies in the fact that it does not always work, many jobs are interrupted midway thru which is extremely irritating and gets expensive when cutting for a large job. No I would not recommend it.
