Thursday, November 15, 2007 8:32 AM Hi larry Well after trying a cheap ebay adapter (prolific) and having no joy and then getting a PCMCIA serial and finding i had no way of changing the com port from 5 to 1-4 required for the software . I got one of your adapters from GPSbits in the UK, now bearing in mind this was causing much stress and hours of internet searching , connected it up driver installed fired up the software little link LED lights up , then click go online and success the little transmit and reciever leds blink away and i have a screen full of data :-) so just thought you might like to put this on your site as i'm sure i'm not the only one with this problem . So SMT6 piggy back engine management by www.perfectpower.com works great with the little purple box of magic ! Regards Gary
VISTA NEWS: July 2007, All our CD's now have Vista drivers, and XP, and 98, etc. BUT NOT 64 BIT versions yet, but soon!
Vista news Feb 2007: Do not load our driver CD - just plug-in and let Vista find drivers on-line! (revised July 2007, you can run our CD now, Vista drivers are on our CD now).
Vista News, 6th Dec 2006, California, USA :
Dear Larry, I went ahead testing your USB to Serial device against Vista....I tried all versions of Vista, there are five separate versions. Good news. They all work! Vista automatically found a driver for the unit and I didn't have to use the CD you supplied. Just wanted to give you a heads up that everything came out OK and your device has no issues at all with Vista. Antuan.Great news, and what's more even better (for us:) Antuan said several other units he tested did not work with Vista!
Feb 2007, Carol in San Jose needed to sync her Palm Vx to her HP dv800z laptop (which has only USB), she found us, bought our USB-G4, and reports back:
The adapter arrived today and it worked--just like you said it would. I'm sooooo happy. Been struggling with this problem of getting my Palm Vx to synchronize for over a year! You guys are great! Thanks for the courteous, speedy service. Carol,
FIREWORKS! (news June 2007) we are honored to be chosen by ODA Enterprises to be the exclusive provider of USB-serial adapters to all their customers world wide. We sell and support this unit in over 20 countries! Everyone loves fireworks and we love helping the show go on.
Woha, news April 2006, the GARMIN support people are telling customers to go to PFRANC.COM!!!!! How cool is that? (BTW we LOVE GARMIN! GRMN stock is over $100 per share! -more here. BTW: A little interesting sub-fact, Garmin sells the same unit I do, made by the same company (MCT) but Garmin sells it for twice as much as I do! But hey, they are busy growing a $billion company so are finding it difficulte to support these non-GPS things they don't make. Garmin's part number is: 010-10310-00. I introduced Garmin to this MCT unit back in the year 2000.
June 2006 news: For several months now, Suzuki Marine has been telling dealers who are using it's engine diagnostic computer systems to call Purple Computing (that's me) for "the" USB-serial adapter that works (with my support that is:-) and so far we have had 100% success.
-*--- Jump down to Latest DRIVERS HERE.
Notice: Our drivers are "signed" by Microsoft now! We include the drivers on a CD with a full "install shield" with every unit! (btw: this phrase I wrote a long time ago on this page and it's a little goofy, so I was surprised that someone would copy it, ... do a google for "our drivers are signed by" and notice that Rad can't manage to come up with his own words? (1/11/07) geee Rad, I'd be embarrassed.
All our USB-serial adapter cables have a cool translucent PURPLE plastic case/housing so you will know for sure that it's OUR unit, made for us by MCT, supported by us, and is the latest and greatest version. Why PURPLE? Well my company (one and only since 1983) is named Purple Computing. Oh, and unlike my new found competetor, Rad, I have only this one little company and only one web site selling, only this one model. Rad told me on the phone he has thousands of web sites selling these things and he'll crush me out of business. Well, I'm still here Rad. Not easy for sure because he's a powerful force in the internet marketing game. I don't know how anyone could survive when he decides to go after you.
There are lots of other USB-serial adapters, some look the same, some are old surplus, some new, several different chips and drivers, some work for some things but not others, one on eBay is selling for $1.99, --- how to shop, what to do? One thing, make sure it has drivers for your system, don't ever say "yes" to that "are you sure" question Windows asks you, just take the unit back and get your money back, there is no need to take that risk anymore. But the easiest way to shop is call me, or read the rest of this page. I know, understand, and have supported this one model since the year 2000, and I will continue to - for the duration. Not for every possible application in the world, but some, and everything Garmin related for sure,... and we (me, Ardel, and Richard here in Oregon, and our Pfrancs in 20 countries!!!!) always have the newest hardware and drivers, - So --- BUY NOW ---> scroll WAY down this page - or click: find a dealer (aka Pfranc).
Wow, this page is getting big - and lately it's getting thousands of visits a day - so maybe I should organize it? Yeah, right after I organize my office, - that'll be the day. Hey, I'm too busy having fun helping folks get a serial port added to their new laptop.
May 2006, .... news: ... Works with Megasquirt - MegaTune (fuel injection computer) applications! (more here).
May 2006, ... still new things people are using our adapter for!
Hi Larry, my name is: Chris. I just purcased your usb to serial converter. i just wanted to say thanks and it works great. i am in the 2 way radio business and program radios for 911 centers and emergency officials. this product allows me to use my new up to date computer without a built in serial port in my daily business. thanks alot, chris hobbs --------- end of message -------
Many of our customers are using it with a Meade telescope - here a fellow Oregonian reports his success:
Friday, July 27, 2007 9:33 AM Hi Larry, my name is: Galen up in McMinnville. I just wanted you to know that the USB-to-RS232 converter you sent me a few months back has been working flawlessly to communicate with my Meade ETX-105 telescope with Autostar. The other "brand name" adapter I was using just wouldn't work in this application no matter what I tried. Your adapter worked out of the box and has not given me even a single error in over 3 months.,, and the cost was very reasonable. --------- end of message -------
News: Nov 2005, Do you Linux? Check this out here: eTrex, Kismet, GpsDrive, Google Earth!!! ... once again a happy customer (Chris in Switzerland) is helping all of us have more fun with a Garmin GPS, computers, awesome software, and our little USB-G4! Thanks Chris! -- it's a WIKI page subject to change/edit/deletion at any time so I made a copy here. As of 11/18/05 the Wiki page was accessed 7 times. ... Um, sorry to make this page even MORE a mess but if you've not used GOOGLE EARTH set down your beer and go do it now! Then imagine using it with your GPS! ... just a glimps of the awesome fun things to come. For now it's time for a beer. --- I'm getting so much Linux info/feedback I started a page just for Linux serial adapter issues. If I had another lifetime I'd spend it with Linux.
News: July 2005, Magellan Meridian Platinum GPS? What's a Magellan? We are 100% Garmin. I don't have a Magellan so can't support it, but that has not stopped our customers from buying our USB-G4 serial to USB adapter! Yeah I've got a little margine but not enough to spend too many hours trying to help get things going, but he buys it anyway and guess what? It works! You can find more Pfranc Magellan news here. Still, I'm staying with Garmin. As Cramer would say: "Garmin's for me."
News: June 2005, ... Works with MotoSAT the Direcway Internet dish auto positioner - according to Ron. He tried units from two other suppliers without success and then tried our Purple USB-G4. He says: "... worked perfectly. ...process was flawless ... Your product and service are exemplary." Thanks Ron! BTW Ron is actually: Professor Ronald A. Howard Professor since 1965, School of Engineering of Stanford University. Did you see that? STANFORD! Where Knuth (the father of Computer Science) plays! Donald, I've been watching 30 years, where's Volume 4?
News: May 2005, ... Works with LabVIEW ( a $4095 software program for engineers ). You know, we started helping folks make a cable for their Garmin GPS in 1996, then in the year 2000 some new laptops were being made without a serial port - so we looked into how to add a serial port via the USB bus but discovered countless problems. Because the problems were so diverse and our limited resources (one technical guy - me) we concentrated on supporting only the relatively small Garmin GPS community (5 years ago), but now that we have that success, and thanks to many thousands of great customers who try our adapter for other things and tell us about it, and because of Windows XP, new hardware and improved drivers, we are learning we can support more applications - like LabVIEW and many others. Click here for more about the LabVIEW success
News: Feb 2005, Works for INDY 500 RACE TEAMS!!!....
Helping folks (4 years now) add a RS232 serial port (via their USB bus) is fun,
and helping small (and big companies) is fun,
but helping an Indy 500 race team is really fun!
I sure hope they win! Here's the story:
Larry, Yes your unit works great with our app. Here's a link! dreyerreinbold.com/racing Thanks, --- Larry Berg

News April 2004: Wow, today I noticed that Garmin (who we love and support the best we can) is selling (looks like this same unit) GARMIN part number: 010-10310-00 (once again), but this time it's a lot better (if Version 2.4+) than it was a couple of years ago ( thanks to Pfranc.com we like to think). I don't know if their photo is accurate. The short version we make (our part number: USB-G4) is more convenient I think, and because it basically adds a standard COM port to your computer, it should have "nuts not screws" because every 9 pin serial port I've seen in the last 30 years has nuts. It's the cables that plug into your computers serial port that has the screws. Ha, don't take my word for it, go check. Still it took me months and months to convince some people. Is it just me? Hey, I'll tell you how much I love Garmin (stock symbol GRMN), I still have a bunch of shares that I paid $18/share for in the 90's, and I'm never going to sell them! Well maybe I'll sell some when they hit $100 a share, but just a little - so I can afford to buy the latest and greates Garmin GPS - ha, maybe a G1000 for my turboprop amphibous ultralight? (Update: 3 years have passed, it's 2007, GRMN went past $100, split 2 for 1 then up to $120!, the question is: did I sell? Answer=no, and I still don't have a G1000 :-(()
News March 2004: Almost everyday someone calls and asks:
"Is your unit the same as U232-P9 (U232P9)?". The caller
was told to go to Pfranc.com and buy a U232-P9. Why?
Well because there are a lot of units being sold out there
that simply just don't work. Anyway, the answer to the
question is yes -- our unit is MCT part # U232-P9, however!
- Always a however - that model number is not enough. You
want VERSION 2.4. MCT makes these units for other companies
and they make a custom version just for us.
Our part numbers are USB-G4 (for the
4 inch version) and USBdb9m for the 6 foot version.
Be careful. MCT (a giant contract manufacture in Taiwan)
has revised the hardware and the software drivers several times over the
years and the model number alone does not tell whole the story.
You absolutely want the newest version, which is U232-P9(2.4).
Or just order from us (or one of our distributors). We've
sold and supported this product since early 2000 and
helped MCT, Garmin, many application software providers,
and countless end users find and fix the problems.
Two customers have confirmed to me in person that our adapter works with Garmin GPS + XP + The Capn software! (13-June-03)
Some Windows 2000 systems want to install our Win98 drivers for some strange reason! Don't let it. It won't work. During the new-hardware-install-wizard dialogue, look for a checkbox named [x] INSTALL ONE OF THE OTHER DRIVESR" and check it. Then look for the driver for Win2000 (which is not easy to see because you have to scroll the window left! argh!).
-*--- Jump down to Latest DRIVERS HERE.
Each USB-COM device has a unique serial number inside that Windows reads and uses to "remember" which driver and what COM port number to use, etc. for that specific device. This means you can set one unit to be COM-52 (via Device Manager) and another as COM-3 and they will remain that way even when the devices are unplugged. Not knowing this can lead to a lot of confusion especially if you have more than one USB-COM device and more than one computer. Windoz considers a COM # “in use” even though the corresponding USB-COM device is not plugged in. You can override it with device manager. Long ago I thought the device itself was "remembering" what COM port number it was, but I was wrong, it's Windows and so is specific to each Windows system and each unique (via serial #) device. Very cool, but if someone doesn't tell you this stuff, it's very hard to figure out on your own, at least it sure was for me. Is it just me?
APPLE - Mac - --- yes!But not if it has an Intel CPU !:-((
I don't have a Mac and I really can't personally support it
but many of our customers are telling me and teaching me that
our purple USB-G4 is working well (with a little knowledge) and
Mac users are really cool customers:
MORE Mac news: (6-Feb-03) OS X version 10 drivers are here!!!! (I mean there on MCT site). Go get 'em! I got a report from Europe today that they work!
MAC news: 20-Jan-2004..... a patch for OS 10.3 (Panther). A customer helps us help others. Go up a few lines and click on "Virtual COM ...." link.
MAC: Our old OS X MAC drivers are new enough?...news Feb 2005: ... Sam said; " I downloaded 10.0.2, which is for one of the earliest versions of the Mac operating system OS X. However, the device driver interface usually is not changed in later versions of the OS. The downloaded version worked just fine with my version, 10.2.8. (The latest version of OS X is 10.3.8; version 10.4 is expected later this year.)"
I'll be adding a lot more info on the pages at the links above to try and better support Mac users with this product, even with the newest OS X, but you know, there is a fantastically great company named Keyspan who really knows how to support a Mac with a Serial-USB device way better than me. It may cost a little more but in the end could be worth it. Check out KEYSPAN (click here).

News: - XP drivers Reports below: -- we love XP! it works! Well, it works better anyway.: and now we have MICROSOFT APPROVED DRIVERS!
News: Belgium, 6-Feb-03 (Jean-Louis is Pfranc of Belgium and stocks our USB converters.)
----- Original Message ----- From: "Lerinckx, Thierry"PROBLEM:Sometimes Windows thinks a GPS (or other serial device) is a mouse! At startup, after Windows sets up the USB to COM port converter, it looks to see if a serial mouse is attached to the COM port it just setup and under some conditions thinks a GPS is a mouse! Two customers told me their laptop running XP thinks their Garmin GPS is a Ballpoint mouse! And then it won't let you use your new COM port! Not nice!
SOLUTION: Click: Control Panel, System, Hardware, Device Manager, Mice, Microsoft Serial Ball Point, Actions, disable, OK. Reboot. (this info thanks to Rick, via Ed Johnson via Joe and Jack\'s GPS web ).
Problem: Our converter would transfer lots of data then up and lockup!
USB is not simple. There are HOSTS and there are DEVICES. DEVICES (like a mouse, keyboard, modem, and your PDA) can connect to a HOST (like your Desktop or Laptop) ONLY! Devices do not connect to Devices (not yet anyway, watch for OTG and tell me when it arrives!) A DEVICE is so complex it needs to have a little computer inside. A HOST is even more complex because it must manage a bunch of devices which are attached to it in a "party line" configuration - all wanting to talk and party at the same time - what a mess. A USB Device cannot connect to anything other than a USB HOST - no way, no how, period. Click here to learn WHY.
I was told that the new HP iPAQ 1910 and Dell Axim do not offer a serial port. The 1910 I'm not sure about but the Axim does, just that you need a special TTL to RS232 (spell expensive) cable. (it wouldn't be so expensive if they would use my patented circuit, but you know how they are, it not their money, it's yours!:-)
A USB Device (key word here is "device") cannot connect to a serial port. It's impossible because a "device" must connect to a USB "host" port - period - end of story.
A USB COM adapter is a very complex USB Device that contains a little computer and a real serial port, and together with special virtual COM port windows driver software lets you add a serial "COM" port to your computer via its USB bus. This is just a small sample of why USB-to-serial converters do not "just work" in all situations. It means that you may not actually end up as happy, or be as lucky as the people here (below). However, most of the time they can, and do, appear to "just work", as you will see below, and it's really great when that happens! --- Someday we hope to figure all this out so we can tell you where and when it will work and not work and why. I'm trying to learn how to write my own Windows drivers so I can better understand and fix the problems. It's not just our converters and drivers, but all of them! Until then - the best we can do for you right now is to tell you everything we know and do everything we can to try and get it to work for you're application. I started out just wanting to support just Garmin GPS's with plugs and have now somehow become the #1 importer/distributor/re-seller and "product advocate" for this USB unit made by MCT in Taiwan. Thanks everyone for your patience, understanding, and help!
(received 11/19/02) -- Our USB converter was not working for Doctor Prugent in Argentina in his laptop running Win2k and Oziexplorer until upgrading to V.3.90 Hi Larry Your USB-G4 is working OK, I´m using the OziExplorer with Garmin 12 XL GPS. I got the final solution when I Upgraded the Oziexplorer to V.3.90 Thanks to your serial/ USB adapter I saved a lot of money in aspirins. Thank you very much My best Carlos Dr. Carlos A. Lac Prugent Vicerrector Académico Universidad CAECE http://www.caece.edu.ar firstname.lastname@example.org Tel: (54) 11 - 5217-7888 (received 11/07/02 - funny, the USB VID for this product is 0711 - lucky numbers, lucky days.) Hi Larry, my name is: Brian in Fredericksburg, VA. I got your USB to RS-232 adapter today. Thanks for being so prompt in shipping this great product! Just a positive comment- I have a Sony GRX series laptop which has no built in serial port. Sony is happy to sell you their 'docking adapter' with one serial port- for over $200.00! Well, it took me about 5 minutes to install the drivers for the USB-RS-232 serial adapter and my ICOM R-8500 is talking flawlessly to my Sony laptop. It also let me hook up and talk to a Radio Shack Pro-2067. (same thing as the Radio Shack Pro-92 and a couple GRE scanners.) I'll let you know how things go in talking to GE/Fanuc 90-30 PLCs in the next week or so. Thanks again! .....Brian..... (you can add this to your 'satisfied user comments' section if you wish.) --------- end of message ------- (note from larry: remember, this device does not work with everything or for everyone. It's so easy to install the wrong drivers or to have older software that can't deal with USB devices well.) Hi Larry, (Received 10/23/02) It works just fine now! It took me a while to find it, but an update was buried on the National Geogrphic site. To shorten the process for other customers, if they are using TOPO on XP, they need TOPO 2.75 which is just out, so on none of the CDs. Thanks for your help Steve ((((( Thanks Steve, The main message/lesson here - again - is this: THE APPLICATION SOFTWARE can work with real COM ports yet NOT work with USB converters! Everything has to be bug free, the OS, the USB converter drivers, AND the application! larry, pfranc.com)))) Hi Larry, (Recieved 9/27/02) Your cable works great. I have a Garmin Color StreetPilot GPS unit in my truck and new HP computer with XP has no serial ports. Just as you indicated, the computer thought the GPS was a mouse. Once I disabled that not so great Windows Plug-n-Play feature, it worked fine. I'm running ESRI's Arcpad 6.0 to view my location on custom made maps on the large laptop screen along with the normal StreetPilot display... Too cool! Thanks, Mark Hi Larry, (Received 9/15/02) Happy days are here again! Just received the converter a few minutes ago. Installed it on my laptop running XP Pro. Hooked up my Palm IIIx and synced without a hitch. Thanks for a great job. BYE Hi Larry, (Recieved 8/29/02) Just bought 2 USB>serial converters to interface my laptop to my robotic telescope (Meade LX200) and CCD imaging setup. They work great! The telescope has 2 RS232 ports to control pointing, and the autoguider uses a third (provided for by the laptop's existing COM1). Without your converters I wouldn't be able to run the 'scope under computer control. One slight hassle (solved) was that after installing the drivers my Logitech trackball was no longer recognised. I think the problem was pre-exisiting and due to a conflict with the Laptop's built-in pointing device (one of those touch-pad things). Anyway, the solution was to go into the BIOS and select the option to disable pointing devices using IRQ12. The Trackman re-appeared and it works fine now. Hi Larry, (Recieved 8/26/02) Thought I'd let you know that your converter arrived yesterday, and it's working good. I use it to connect a Yaesu FT-817 ham radio to a HP Pavilion laptop running XP. The application is a program called 817 Commander which allows you to control a transceiver with your computer. All that was needed to make it work was to change the COM# that the adapter and XP assigned from COM3 (which my modem was trying to use!) to COM1. Now I can drink my beer and operate my radio at the same time. It's a life saver! GySgt J. Dunton MCAS Futenma, Okinawa Hi Larry, (recieved 8/25/02) Just wanted to let you know that it works like a charm in Red Hat 7.3 :) All I had to do was plug it in. No configuration necessary. Drivers were already on the OS. Thanks again! Brian Hi Larry, (recieved 6/7/02) Sure you can publish my results. After testing 13 different USB-to-Serial Adapters, only yours and one other work with all my gear. It seems that only these two fully implement all the control signals in RS232! It works fine in XP too. Regards, Richard Baldwin Hi Larry, (recieved 6/5/02) Another success story for your serial-USB converter! After failed attempts with both Belkin and Palm's converters, I installed yours and it works GREAT! My Palm Vx, MindPath IR50 infrared mouse, and Nextel cell phone dialer are all working properly on my Dell X-200 laptop with Windows XP Pro. A couple of hints for others that I learned the hard way. HotSync "highjacks" COM4 if you allow it to open at Startup, so I removed it from the Startup menu and open the software manually. Also, the "virtual port" doesn't respond well to "standby" or "hibernate" modes, so be sure to exit the application and remove the USB cable before putting it into either of those modes. THANKS AGAIN for saving hundreds of dollars of serial port appliances! Take care, (another) Larry Hi Larry, (recieved 5/21/02) Nice talking with you last week on the phone. The USB to serial converter arrived today, and it took about 5 minutes to get it set up and working; my PALM IIIc is now talking to my laptop running WINDOWS XP Pro. I had originally purchased a converter from PALM, because I did not want to waste time with a converter that would not be compatible with PALM products. BIG MISTAKE! To make a long story short, I have yet to get the PALM converter to work after HOURS of fiddling with it - yours took about 5 minutes to get up and running. Thank you for a great product, and good luck in your endeavors. I will tell others of your superior converter. Ron Schuetz Hi Larry, ( 15-Apr-02 ) I am running C-Map digital marine charts on an IBM laptop (no serial port), XP Pro. I just plug in yours and my yacht's position appears on the chart. I tossed my Belkin (USB converter) overboard! Thank you for the great service and product.

Download the latest drivers on-line!
Click on "SUPPORT" at the top of the page, then
under Download in the left menu click on "Driver".
Choose "USB Connectivity" then U232-P9.
It's a very rare thing now to have to download drivers as we
always have the latest on the CD we ship with every unit,
AND - guess what? The new Vista machines new-hardware-found wizard goes on-line
to a special microsoft.com place and find and load the
drivers for our unit! So just be on-line, plug-in, and off you go!
No CD required. You can check with Device Manager what COM port # got assigned,
you'll find our unit right where it belongs under Ports-COM-n-LPT.
Note: March 2006 I added a new page just for Linux issues!
Joe Philipps in Buffalo, NY, Linux users can use the "mct_u232 driver in drivers/usb/serial". Searching for "MCT P87C52UBAA" Joe discovered it in the kernel source. (Thanks Joe!) Also check the Driver here! -- A customer named Roelof JT Jonkman (roel\@SiliconDefense.com) pointed me to these places for lots of great Linux-USB info, http://www.linux-usb.org and http://www.kroah.com/linux-usb. He said you can contact him with Linux questions as he bought one of our converters and got it to work! (Thanks Roelof!)
