I also like the software that comes with it, which allows you to actually see the data that is being transferred through the serial port.

I have purchased several - at different times - for both business and home use and have always found them to be utterly reliable; very simple to use and with what seems to be rock-solid software behind them

The included software is useful.

Pros: software and drivers for the Mac

The software for the CarChip would sometimes freeze with my old computer with the serial interface

I plugged in the adapter, started the MX-800 software and configured it to match the serial port (in my case COM6) and it worked perfectly!

I develop software that connects Win 7 x 64 bit computers to older industrial machines through RS-232 connection .

Once the software and hardware was set up correctly (communication ports, etc) everything worked great

No other cable that I tried worked or included the correct software to do this.

The software loaded up fine and it worked the first time

A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source

The software that KeySpan makes available for configuring and monitoring traffic is also very handy for troubleshooting connections.

The software is very easy to manage and works easily.

The software is easy to load and use

Installed the software and it worked first time.

Not a technical review, but I installed the software and it worked as it was supposed to

Since the adapters still work fine except for the USB port, I simply desoldered the cheap-o port from each of the new adapters and replaced it with an FCI port (FCI PN 61729-1011BLF -- 54 cents each)

I know this cable is much more expensive that the cheap-o ones you find elsewhere, but if you're a Mac user, don't waste your time with any other USB-serial cable.

Works as it should once I

Works as it's supposed to.

As a matter-of-fact it is the only rs232-to-usb I would recommend as it is the only one I tried that actually worked!!

I plugged in my serial devices to the Keyspan and they worked just as they did when I plugged them in directly to a serial port

Unit worked exactly as it should, don't waste you money on cheaper ones, this is the one that works

Not a technical review, but I installed the software and it worked as it was supposed to
