But unfortunately its not freely available (like FTDI on their site).Does anyone have this tool for me, so I can test my interface with a custom VIDPID Thanks.
The PL2303 is a standard USB-to-serial converter which has a default VIDPID. If an external EEPROM is connected, a custom VIDPID can be set. The problem is that no information is available about the contents of this EEPROM. Pl2303 Eeprom Writer Utility Software Software Tool CalledA software tool called EEPROM Writer Program is available to program this EEPROM through the PL2303 itself, but I cannot find this tool anywhere. In the past, it was freely available on the manufacturers website, but now not anymore. If any body have that documentation Please give me a link or upload.

Feb 26, 2008. This application note provides the latest important migration guidelines for PL-2303HX Edition. The table below shows the software comparison for all the PL-2303 chip edition series. That the PL-2303HXD is using a newer version (1.0.0.5) for the EEPROM Writer program (see. Nov 27, 2010. First post here (sorry its quite a length one). Heres the problem - I have two USB to serial adaptors (identified as using the Prolific PL-2303) which arent identical in appearance but appear the same when detected by OSs. I would like to be able to identify them through software without having to know which adaptor is plugged into which USB bus or whatever. If serial device X is connected to adaptor X and serial device Y connected to adaptor Y, when in linux the kernel can detect an assign these USB devices different device names between reboots. Ive compared the devices in Windows Device Manager, and also with lsusb -v in linux and theres little to distinguish between them. Ive read the following thread from this forum about being able to reprogram the EEPROM - edaboard.comthread62529.html - however for adaptor 1 if I leave the eeprom writer program settings as default, change the serial number or the PID and press write, I get an error message Compare EEPROM failed Followed by an alert Write EEPROM successful But it clear isnt as the PID hasnt changed and (although Im not certain I know where to look for the serial number) the serial number doesnt appear to change either when reviewing device info (nothing seems to change). ![]() Since that first time of using the EEPROM writer with that device, I get exactly the same behaviour as adaptor 1 when writing. When trying to read the EEPROM I get the alert message The EEPROM isnt programmed yet, confirming the previous writes dont seem to have done anything. Ive also read jethomson.wordpress.com20100221diy-usb-to-serial-cable-for-3usd which in the last two paragraphs mentions the following from the blog owner: I looked into this, but my memory is a bit hazy on the details. IIRC you need a special USB board that puts out 6V to program the EEPROM in the rev. ![]() Books by Charu Nivedita, Kaavuum nnum, sti-- sti-- sti--, Matumit conna pmpu kataika, Kmarpa kataika, Ticai ariyum paravaika, Cinim cinim, Trkktali, Tirakkatali. A has a 2-wire EEPROM interface though, and I think if you program an external EEPROM correctly you can tell the PL2303 to report itself as High Power device and therefore get 500 mA from the USB port. If you get it to work, write back and let us know Ive also emailed Prolific to ask for access to their versions of the EEPROM writers as one of their product sheets for the 2303 suggests that EEPROM writers between the different versions of the adaptors (X, HX etc) arent compatible. If anyone has any info to help with this, it would be greatly appreciated - seems Im running out of things to try. First you should make sure you cant differentiate the two devices by serial number.
