IOGEAR USB PDA/SERIAL ADAPTER (GUC232A)

I bought a $3 adapter on another site and it didn't work (at all, despite A LOT of troubleshooting) and left me with no alternative but to simply purchase another. This one is still cheap, is well constructed and works as it's supposed to work.

Pros: Until it crashes it works great.Cons: Iogear has still not released an updated driver, and their current version causes a BSOD in Windows 7 as described by the previous reviewer. I contacted Iogear support, and the email response I received said that there was no problem with Windows 7 and their product is fully compatible. Obviously not.Until it crashes it works great. Iogear has still not released an updated driver, and their current version causes a BSOD in Windows 7 as described by the previous reviewer. I contacted Iogear support, and the email response I received said that there was no problem with Windows 7 and their product is fully compatible. Obviously not. I can't recommend this (or even use it) until they fix their driver, which they now deny is an issue.

It would not work with my digitizing tablet out of the box, and neither manufacturer could get it to work. I had to return it.

Pros: kinda works?Cons: My first windows 7 bluescreen was caused by this adapter. Garbles input & output. Drivers haven't been updated in a while, good luck with this guy.kinda works?

Pros: It's pretty good. Works on PC, Mac, Linux. I've been using this for well over a year.Cons: I use this with a Mac with Cisco devices. Be warned that there is a serious bug with this and the Cisco 4900M switch with the default driver. There is an open-source driver out on SourceForge that you will want to use instead. It's the chipset's fault.It's pretty good. Works on PC, Mac, Linux. I've been using this for well over a year. I use this with a Mac with Cisco devices. Be warned that there is a serious bug with this and the Cisco 4900M switch with the default driver. There is an open-source driver out on SourceForge that you will want to use instead. It's the chipset's fault. It's a pretty good device, but there is cheaper out there that will do the same thing, and there are better chipsets out there. Still, this isn't all bad.There is another low-end review here that also mentions the chipset issues. I would assume this guy is correct, based on what I've read and my personal experiences with this thing. I would not use this for PLC stuff.

Does exactly what it says, and works well with OSX. I've had several of these for years and have had zero problems with them.

Pros: Works without driver on SuSE Linux 11.1 /dev/ttyUSB0 is automatically created.Cons: On Windows XP, I need to load the driver. Else, the device is not recognised.Works without driver on SuSE Linux 11.1 /dev/ttyUSB0 is automatically created. On Windows XP, I need to load the driver. Else, the device is not recognised.

Pros: This is the easiest, most reliable USB to RS232 adapter I've used.Cons: None really; note this is about 16.5" tip to tip so some applications may require a serial or USB extension cable.This is the easiest, most reliable USB to RS232 adapter I've used. None really; note this is about 16.5" tip to tip so some applications may require a serial or USB extension cable. I've purchased two of them (I lost the first one only to find it the day after the second one arrived - typical) and am pleased with both.

Pros: Works just as it should. Not many cables out there that work with 64bit systemsCons: I wish it were cheaper.Works just as it should. Not many cables out there that work with 64bit systems I wish it were cheaper.

Pros: Works perfectly. It interfaces with the MSD ignition in my friends drag car perfectly. Downloads and uploads the files fast and hookup was easy. Software was available for the newer windows OS on the weblite and no problems with download and install.Cons: noneWorks perfectly.

Software was available for the newer windows OS on the weblite and no problems with download and install. none I just wish the cable was about 36"long. The cable is only 14" long and I have to place the laptop on the carbon fiber body to connect to the MSD ignition. I have to use a mat under it to prevent scratching the finish. I will try a serial extension cable.

Pros:Durable construction, Highly Compatible, Reliable This adapter uses the Prolific 2303 chipset. It works with Mac OS X and Windows 7. The best drivers can…

Pros: Works as designed. No issues on Windows 7 64.Cons: As others pointed out, you may need to download the drivers, but this only took a minute.Works as designed. No issues on Windows 7 64. As others pointed out, you may need to download the drivers, but this only took a minute.

The IOGear USB-Serial 9pin interface GUC232A is completely compatible bi-directionally with various modems and Garmin GPS units. Power is from the USB port. The installation process could be better. The CD instructions identified a WinXP Pro OS as a Win2000 OS. During CD installation, a needed driver file is not automatically installed - you need to find it on the CD in the Drivers folder. A reboot was necessary. however, the product is reliable with no failures from several copies purchased over the course of a couple years.

Pros: 3 yr warranty-works with Vista 64Cons: No Vista drivers on CD--Had to down load the drivers from website. Vista drivers should have been on the CD by now--Gosh Windows 7 is almost here.3 yr warranty-works with Vista 64 No Vista drivers on CD--Had to down load the drivers from website.

Pros: Worked perfectly out of the boxCons: noneWorked perfectly out of the box none

this does not work on a Mac.

Pros: Since laptops usually don't have serial ports on them any more I looked around and people said they could use it on mac to use Hyperterminal on various Cisco switches.I bought the product and downloaded the drivers from the website. Extracted the drivers installed the device and didn't have any problems.I can use Hyperterminal and Putty on these Cisco switches and didn't have one single problem. I am using a Macbook OSX Leopard and Vista Business (bootcamped) and works 100%Cons: NoneSince laptops usually don't have serial ports on them any more I looked around and people said they could use it on mac to use Hyperterminal on various Cisco switches.

Pros: Plug it in and it starts working right away, no hassle. Nice flashing LED.Cons: This will not work for old style APC UPSs that use Powerchute Business Edition. After a while the UPS will lose the serial communication. I replaced this with a SIIG PCI serial card and now the UPS never loses communication.Plug it in and it starts working right away, no hassle.

Pros: Well made. Good Reputation for most applications. They used to have Vista driversCons: There used to be a downloadable Vista driver but not now. If you look for the GUC232A Vista Driver at the IOGear site you see a list af drivers for various operating systems. The zipped driver for all but Vista is a file (GUC232A.zip) about 100 KB in size. But the one for Vista is called GUC232A-V.zip and is 1.76 MB in size. This turns out to be a single file (setup.exe) which is 2.012 MB in size and when run just tries to install a driver installer putting an empty ATEN folder in the "Program Files" directory. As a result you can't browse to any driver when prompted becuse there isn't any. IOGear has not explained this or sent a Vista driver.Well made. Good Reputation for most applications.

We need a product like this to run legacy RS232 audiologic equipment. I'm hoping I'm overlooking something and another user will spot it.

Pros: Connects to Vista just fine. I used the latest driver off their site.Cons: NoneConnects to Vista just fine. I used the latest driver off their site. None

Pros: It does send a true break signal. I'm using it with XP-SP2 and TeraTerm, physically connecting to a Sun Fire V240 console port and it does work. You get one yellow LED as feedback. When sending break it lights for one second. When the Sun spins the cursor you see the LED briefly flash, so it combines TX/RX feedback into one LED. For Linux use minicom for a VT emulator on a com port.Cons: Drivers are on included CD, i.e. not on Microsoft's site.It does send a true break signal.

Pros: Its a USB to Serial Converter that actually works, what more can you say.Cons: NoneIts a USB to Serial Converter that actually works, what more can you say. None

Pros: Works great, installed the latest driver, which also supports Vista! The break command works for Cisco equipment which a lot of other USB to Serial adapters do not support! Also has Mac OS and OS X support!Cons: NoneWorks great, installed the latest driver, which also supports Vista! The break command works for Cisco equipment which a lot of other USB to Serial adapters do not support! Also has Mac OS and OS X support! None Not sure if this works with x64 editions of Windows as there is no driver.

Pros: Works as long as 128kbps is okay for your device. A V90/92 needs more.Cons: Claims 232kbps but tech support says this is limited by the O.S. Not true. My USB modem uses Windows usbser.sys and develops a 232kbps port. The prolific ser2pl.sys limits the adapter to a "Slow" 128kbps port. I believe it is the Prolific driver limiting the speed.Works as long as 128kbps is okay for your device. A V90/92 needs more. Claims 232kbps but tech support says this is limited by the O.S.

I believe it is the Prolific driver limiting the speed. RS232 experts on the web say 232kbps is necessary to keep up with a v90/92 modem due to modem compression. Any USB->Serial adapter based on the Prolific chipset can't exceed 128. In the RS232 world, a 16550 is 128kbps, a 16C550 is 232kbps. There are specs that increase from there (16650, 16950, etc.) For a modem, I think I need an adapter that will mimic, at least, a 16C550 at 232kbps.

I was searching for a no-brainer way to connect my Lowrance M M GPS to my Mac G4 Powerbook. This was recommended by a co-worker who had gone through several difficulties with other adapters. It was so simple and it worked perfectly the first time. Driver installed quickly without issues; plugged it in and it worked. Superb product.

Pros: Windows XP native driver worked flawlessly. Alows for choice of any Com port.Cons: None for me.Windows XP native driver worked flawlessly. Alows for choice of any Com port. None for me. I bought this unit to interface with my Suunto Vyper dive computer. It worked flawlessly in minutes using the driver installed by XP. It doesn't get any easier than this.

Pros: Plugged it into my laptop and immediately used it with my MSD computer ignition software to tune a radical 63 vette. It doesn't go to sleep, so for reporting applications it is perfect.Cons: nonePlugged it into my laptop and immediately used it with my MSD computer ignition software to tune a radical 63 vette.

Pros: Works with Garmin GPS... eventually...Cons: The instructions say that driver installation may be difficult in Win XP if there is no Serial port already installed. Well, if there was, then I wouldn't need this cute little device... Let's just say it reminded me of when Win 2000 came out and no one had drivers available yet...or even like now, getting drivers to work in Win XP x64. If you have XP and want to use this device, use the driver on the cd under XP Drivers that is NOT certified for use with XP. The one that IS will NOT work... trust me...Works with Garmin GPS... eventually...

Pros: Works. FB for laptops with no serial ports.Cons: Have no idea where the driver disk is anymore as Windows always loads it up fine.Works. FB for laptops with no serial ports.

Pros: Worked out first try with the serial touch-screen monitors we have at work.Cons: noneWorked out first try with the serial touch-screen monitors we have at work. none The install cd, although it claims to install drivers, either didnt seem to do so, or it did it incorrectly.. might as well skip their install app and search out the drivers on the cd..

Pros: It simply works!A couple of weeks ago I purchased a Syba SY-USB-S USB to Serial adapter to use with my Magellan SportTrak Pro and my laptop. It is not configureable or adjustable, it defaulted to Comm 6 so making it useless for older serial devices that use only 1-4. A waste of $12, it's going in the trash.The IO Gear is a different story, it works like charm! The software driver is much better written and simple to change settings.Cons: It costs more but it's worth the extra money.It simply works!A couple of weeks ago I purchased a Syba SY-USB-S USB to Serial adapter to use with my Magellan SportTrak Pro and my laptop.

Strengths:Provides a quick and easy solution if you need an extra 9-pin serial port ... Weaknesses:Breaks down after a few years, cost (> $20) Setup of this cable is quick…

Pros: One of the reviews I read was from a gentleman who uses these in an IT support group. His comments were dead on. Plug it in, let XP recognize it, and it just works.Cons: None so far.One of the reviews I read was from a gentleman who uses these in an IT support group. His comments were dead on.

Works great with Linux! Another USB to Serial adapter would read, but not write. I tried this guy and he worked great! (right out of the box - no driver installation required).

This device gives you a 9 pin serial connection for use with PDA s and Blackberry, etc. If you only have a USB port free then this will make the USB work as a 9pin D-Shell Serial Port. Drivers for Windows are on the CD included. Can be set-up as Com1 - Com9.
