USB to Serial Adapters

Eric and Lance,
the pcmcia card to 232 works fine burning with Download.exe and hypertrm, to be honest, the price was only £15, this is the way I would recommend people to go as its rock solid

Hi Phillip,

Have you said where you got your card? When I was looking for one
almost 3 years ago the cheapest new one was about 10 times your cost.
Ebay ones were few / far between and also expensive.

Phil,

That's the same price as the cheapest USB adaptor that I got, and is almost certainly much more reliable... Thanks for searching it out.

Guyz I have a laptop that does not have a serial port......so can I use a USB to serial port convertor to do this or how???? Please help me to solve this problem.

Thank U....

The problem I am seeing is that the com port is a moving target. Seems like everytime I run MT the MS is on a different com port. Tonight it was on com10. Since MT only goes up to com9 I am sol. At least until it decides to go back into the single digits.

Ran across this on how to reassign the com port from:
http://www.beaglesoft.com/232usb.htm:

Windows XP port reassignment

1) Follow steps 1 and 2 in "How to Check the Driver Installation."

2) Right click on the "Prolific USB to Serial Port" and click on Properties

3) Click on the "Port Settings" tab. Click the "Advanced" button.

4) Pull down the scrollbar on the bottom, left side and select COM 1, 2, 3 or 4 (NOTE: Choose one that does not say "in use" next to it). Click "OK."

5) Click "OK" again. Notice that the device will show up as being on the same COM port that it was before (i.e., COM5), but will show up on the new port if you close the Device Manager and open it again.

6) Close the device manager. You may have to run the software that came with your device to make it rescan the COM ports.


Now if I could figure out why no one can burn VE or settings with the Prolific cable.

The Prolific adapter sold by SewellDirect (pn SW-1301) won't work on my Sony VAIO no matter how I configure it. It'll pass the loopback but won't communicate with the MS/MSII. Same blue casing and clear cable.

Too bad...

I had the same problem until I saw one of Eric's posts regarding a setting:

interWriteDelay = 1 ; Ignored if writeBlocks is "on".
writeBlocks = off ; or off (default is on)

This is located in the megasquirt-I.ini file (at least for MS-I it is). This is located in
D:\Program Files\MegaSquirt\MegaTune2.25b356\mtCfg or wherever your equivalent is.

"interWriteDelay = 1 ; Ignored if writeBlocks is "on".
writeBlocks = off ; or off (default is on)"

Using this with the Prolific USB to Serial adapter and it works faultlessly (set FIFO buffers ON, Recieve and Transmit Buffers to low (1))

If you put it into a different usb port it`ll assign a new COM value for each USB port, you can force it to use COM4 for example but you`ll have to do it for each usb port you plug it into.

Succesfully flashed the MS, datalogged and written VE tables with it..

Hi Phil,

Is this the same adapter that you purchased?
