- The answer for a Cisco Rack
-
This products works with Windows 8 x64 plug N play no needed drivers and is idea for a Cisco Rack configuration. There is no need for an Cisco Access Server with this product.
Quality Value Price - just plain awesome

I am a HAM radio operator that has been fighting with Serial converters for years this one just plain works on XP, Win7 and Win8.
Quality Value Price - so far I have been unable to get it to work

have tried this adapter on two different computers: a new dell running windows 7 and new mac running windows 7 professional in parallels (my machines only work with windows). While the drivers successfully install the rs232 port does not show my machine connected to it. This is the second usb to serial port adapter that hasn't worked for me. the normal old style rs232 works fine. As the other reviews have been glowing, it may be specific to my machine. The adapter is a nicely constructed item that has a professional look and feel to it with what appear to be good quality cables. I'm sorry that I haven't been able to get it to work. I've tried for a total of about 3 hours. That's about my limit for this particular item. If I manage to get it to work I'll update and reevaluate.
Quality Value Price - Works as designed on Windows 7

This USB to serial port adapter has 4 separate serial cables that connect to a single USB 2.0 plug.
Each of the 4 serial cable ends is slightly more than 3 feet long. The USB cable end is one foot long. Total end-to-end length is a little bit more than 4 feet long.
Each serial cable is labeled "1", "2", "3", or "4" which makes it easy to track your connections. The connections always retain the same com port, so you won't need to reconfigure you software after restarting you computer.
The adapter has 3 separate LEDs: red = power, green = TX, yellow = RX.
The adapter comes with a CD-ROM that contains USB 1.1 and USB 2.0 drivers for many operating systems including Linux, Mac, Windows, and more. The release notes on the CD-ROM mention that newer drivers can be found at [...]
No paper instruction manual is included which might cause inexperienced computer users to have moderate difficulty with the setup. Experienced users will find the setup straight forward and simple.
Installation on Windows 7 was easy for me. I found the appropriate installer on the CD-ROM. I had to right-click the installer and select run-as-administrator. The first time I plugged the adapter in it took several minutes for the device to be detected, so be patient. Subsequent detections are fast.
All 4 serial adapters can be used simultaneously.
Overall I am satisfied with the quality of this device.Quality Value Price - Best USB to serial adapter I've used

This four port adapter has been absolutely rock solid under Linux. I just plugged it in and it worked. I have been using this non-stop for a couple of months now and have had absolutely zero problems. I usually run it at 115,200 baud but have had no problems when pushing it as high as 460,800 baud.
I have used a number of different USB to serial cables in order to work with numerous embedded devices and I always seem to have problems. I have seen adapters suddenly stop working, requiring me to disconnect and reconnect them or having their baudrate suddenly change or just start spewing garbage. Not this one.
The transmit and receive LEDs are also nice to have since they can indicate that something is happening on another serial line I am not currently looking at. The cables are nicely molded with the serial port number molded into each connector.
I am saddened to see that it is listed as no longer available since this is such a great adapter.Quality Value Price - Works Fine On My Ham Radio Applications

I installed this cable on a machine running XP Pro/SP3. I did a Windows Update prior to the installation. I let the OS find the driver on the provided CD ROM, rebooted, and the new COM ports were there. I redefined the ports using the Hardware Manager and the designations have "stuck" so far after about a dozen re-boots.
FWIW, I tried the cable with CTWin, Logger32, and N1MM. All worked fine, correctly communicating with two radios on two different COM ports and a Rotor-EZ equipped rotator on a third COM port. I have not tried it with WinKey as my LPT keying works fine (ergo, I do not use WinKey).
I experienced no RF susceptability problems on 160m-10m at 100W and 700W power power levels.
The "octopus" cables are conveniently long so that I do not need any extensions from the compuer which sits to the side of the radios.
The price of this quad converter is about half of another alternative that was recommended as being proven with Ham applications.Quality Value Price - Works Great!

Nice product, works just fine on my 64 bit Vista notebook, letting me use 4 serial devices simultaneously. I did have to force the drivers to use com port assignments that my computer says were already in use (though they really weren't).
Quality Value Price - Simply works with FTDI drivers on MacOS X
-
Just works with the FTDI drivers. Tested on MacOS X 10.7 Lion and the four ports show up as /dev/tty.usbserial-FTUJPJ7ZA through /dev/tty.usbserial-FTUJPJ7ZD . Cables are quite long.
Quality Value Price - includes Microsoft "signed" driver!
-
I was upset when I first tried to install it on windows XP as the included drivers did not work properly. But MS Update fixed it automatically . A good proper product. Very satisfied.
Quality Value Price - EXCELLENT Product!!

The USB "jungle" under my desk was becoming a nightmare & I was quickly running out of ports on my USB hub to connect my ham radio equipment to, so I went looking for a good multi-port USB~RS-232 adaptor. Between my 2 main ham transceivers, the packet TNC and the internal TNC I needed 4 RS-232 ports that did RTS/CTS handshake correctly (Kenwood radios are kinda picky in this regard {especially the TM-D710A in EchoLink sysop mode}, as is my TNC). I had been told by numerous fellow hams that USB~RS-232 adaptors that used the FTDI ICs where the only way to go, so I limited my search to these. I saw this item on Amazon & read a review from a fellow ham that had dealt with this same issue, and he praised this unit highly, so I decided to purchase it.
I'm VERY pleased with the results. I've hooked up the adaptor to my Toshiba laptop PC (my "shack computer") and to the Kenwoods and everything works just like it is supposed to. There where no issues with the adaptor operating correctly with the radios running full power output (100W on the HF bands & 50W on 2M/70CM) - no "glitches" at all. One thing that had concerned me was possible interaction between the 4 ports when 2 or 3 of them are active (actually passing data) at the same time, which is the situation when running packet. However, no such interaction had been observed.
I would HIGHLY recommend this USB~RS-232 adaptor to any ham that is running multiple radios and/or aux. items like a TNC that wants reliable data transfer when you've got a bunch of RF floating around the shack on multiple bands. Gearmo makes a fine product in this item & I WILL personally recommend it to my ham friends.
NOTE: I would recommend that anyone that uses this product go to FTDI's web site & download the ComPort Reassign utility - it makes Com Port assignment of the ports on this device much easier than using Device Manager in Windows.Quality Value Price
