    Involvement Level: Expert (understands the inner workings)

    Pros: small, works with windows xp, windows 7, 32 and 64 bits, windows 8, prolific chip, for windows xp use the prolific driver 2.0.2.1, for windows 7 use prolific 3.2.0.0, for windows 8 let it to chose the right driver---------> it works for me that way. for more inofmation--------> http://www.miklor.com/COM/UV_Drivers.php

    Cons: at the beggining was hard to find the drivers, but after found this website ( http://www.miklor.com/COM/UV_Drivers.php ) everything works perfect on every single windows from xp to 8.

    Other: Great adapter. I would answer anyone doubts about this adapter. Till now I boutgh about 20 adapters and all of them worked as it should.

  • Good converter, crappy cable

    posted by Cubytus on 12:42:22 G7T 26/07/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: A very affordable way to add a serial port to a USB-only computer. Converter itself is well-built and seems sturdy.

    Cons: No indication as to what the controller is inside. This is important for many USB-to-serial applications. Extension cable is really bad quality, doesn't match the good build quality of the converter itself. Software comes on a small CD, which is bad since many computers cannot take it nowadays. No website to load updated software??

    Other: If you need a converter to serial, this is one good purchase. Will work in Linux. Not sure about Mac.

  • good but had to use good drivers

    Involvement Level: Expert (understands the inner workings)

    Pros: it is a good price

    Cons: The quality is not that good . it is fragile. already broke one. Driver installation under windows 7 are not working out of the box.

    Other: despite the cons it does the job. So reagarding the price it worth it

  • Good product, but comes with a few caveats

    posted by NicknameInUse on 05:13:13 G12T 09/12/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: The price is competitive and the unit comes with an extension cord and driver cd. Build quality is "unpolished" (some sharp edges, not so neat finishing, etc) but very sturdy. After a bit of tinkering it -mostly- does what it should do.

    Cons: As confirmed by Prolific, the PL-2303 chip is not an original, but a copy. This means you won't be able to use the latest official Prolific or Microsoft certified drivers for Windows XP, Vista and 7, otherwise you will just be met by a yellow exclamation mark in your list of devices. Use the drivers on the cd, or one of the older versions many other reviewers have already posted. Unfortunately, I didn't manage to get it to work on all machines I tried it on, nor with all programs and hardware I would like it to work with. My wholly unscientific test gave a success rate of about 65%.

    Other: It's a good product, but as with so many devices with a bit of built-in 'intelligence', it might take a few tries to get it working. No guaranteed success: it all depends on a bit of luck, the OS, the software and hardware you use it with -- and on your patience.

  • It works!

    posted by bob91343 on 00:33:44 G11T 22/11/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Unit works as advertised. I am amazed that something sophisticated like this is so inexpensive, but that's DX's reputation.

    Cons: No instructions; I had to figure it out. The first one I ordered didn't work. DX was very good and sent me another. This one works fine.

    Other: I am satisfied and would recommend this product to anyone who is computer savvy. I had to change the Baud rate and port number to use it, and most people would not know how to do this.

  • cheap usb rs232

    posted by dxlooka on 11:47:57 G6T 05/06/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: -price, definitivly -extension cable included -works with win 7x64 with driver from internet: http://www.usglobalsat.com/store/download/546/win_drivers.zip

    Cons: -does not work with win7 out of the box. -not really well-made, very sharp DB9 connector (could shape bisquits with it:), also usb connector is a bit wabbly -extension cable could be longer (!)

    Other: i haven't tested all speeds, but it works with very basic settings as every other rs232. a must have for any low-level engineer or just diy-er

  • Not true RS232

    posted by critiacrof on 08:17:26 G6T 08/06/2011 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: -great product, my pc doen't have a serial port, so this product is very usefull.
    -great price. At a local store you pay 10 times as much.
    -small size
    -includes a usb extention cable
    -includes driver cd

    Cons: -not a very riggid contruction. In falls appart very easily.
    -not true rs232, it only has positive levels.
    -cable is not good in quality, but this doesn't matter.
    -only rx and tx pins are connected

    Other: Good enough product for most uses, but don't expect it to replace a real serial port.

  • Perfect for microcontroller projects

    posted by bhassett on 04:24:16 G9T 08/09/2010 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: I had no trouble using it with any Operating System.
    Works in Ubuntu without any drivers, shows as a ttyUSB device.
    To use in Debian or any similar Linux, you may need to add the standard modules usbserial and pl2303.
    To use in XP or Vista, insert the supplied CD before plugging in for the first time.

    Cons: There is absolutely no user guide.
    The serial port is not officially RS232 because it only supports positive voltages. However any device built in the last 10 years should have no trouble with this variant of RS232.
    The supplied USB extension cable is very lightweight and is unshielded. It does the job, but just barely.

    Other: This is now my favourite way to connect my microcontroller projects to a PC. It is so cheap that I can put a USB port on every project just in case I might need it for debugging.

  • With MAX211

    posted by verleihnix on 02:59:44 G7T 29/07/2010 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: The 3 I got have a Max 211 or a ADM211. These two ICs are RS232 line driver to meet the specifications of RS232. Levels are -10V to 10V. If you want to use it in a microcontroller project you have 2 possibilities to get it working: 1. use another level driver as the MAX232.
    2. solder the max211 out. TX ist on the old PIN 6 and RX on Pin 19.

    Cons: Some solderings are very bad. I solved this with a few more solder.
    Now it has a level driver. So you have to remove it if you want to use it with a microcontroller.
    I you want to remove the MAX211 be very careful. Its very easy to destroy the pads.
    The PL2303 is glued.
    Had a problem with the driver in Win xp.

    Other: a good USB RS232 Converter but I´m not sure if it has a original pl2303 chip. Got a Code 10 Error in Win xp. Solved this with another driver.
    New Version with level driver. So not so good for a microcontroller project.

  • Ok but you get what you pay for

    posted by xSmurf on 16:16:52 G5T 26/05/2010 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: This is a simple USB <> RS232 converter. Not much to say here. It's the cheapest one available on DX an as others report it's PL2303 based which has wide driver support (now a days).

    Cons: The PL2303 IC is actually a blob of epoxy (and a generic Maxim level converter) making it harder to to this adaptor for DIY USB <> TTL Serial. None the less, the epoxy blob shouldn't stop me as I will tap in on the level converter once I pass the module under the rework station.

    Other: You get what you pay for, as at this low low price, what you get is a blob of black epoxy! ;)
