Review: Great way to get RS-232 on newer computers - For the past several years, I have been using computers that have no RS-232 serial ports. In spite of that, I have several pieces of equipment that I use regularly that still communicate with the computer over RS-232. I put off purchasing a USB to RS-232 converter because of all the horror stories about the effectiveness of this type of converter. After I purchased a new piece of radio equipment that did not offer a USB port for computer-radio communication, I finally broke down and ordered this converter. I chose the 4 port converter since I have so many different pieces of equipment that would be using it at any given time. This is what I like about this converter: - It has 4 ports. This is a very important feature for me due to the number of pieces of my equipment that are still RS-232 only. A single port converter was useless for my needs. - After installation, the different applications and equipment worked flawlessly with the converter. - Communication speeds can be faster than standard RS-232. - Worked on the first try, right out of the box. - It is supposed to work on Mac OS X and Windows (I have only tried Windows so far, but Mac will be set up shortly). This is what I don't like about the converter: - Pricey! But, it has great Mac support that others don't offer. - When installing the four serial ports in Windows, the software goes through a process of warning you that new hardware is found four times. Since this software is not WHQL tested, you also get a warning that this software has not been Windows tested four times. It takes forever to click through all the information pop-ups. If Keyspan would like free, unsolicited advice, either WHQL test the installation software and hardware, or give the installer a "Yes to All" option so that the installation doesn't require so much user attention to complete. As stated earlier, I run about 50% Mac and 50% Windows, so I will be installing this on a Macintosh computer soon. I'll make an effort to update this review for the Mac users out there.
Review: This took a while to get working right. I ... - This took a while to get working right. I needed to download updated drivers from the web to get it to configure properly. Works OK now.
