USB to Parallel converter

March 19, 2009 at 07:19:27
Specs: Windows XP, 512

I am having software exe that will read data from parallel port.
But i want to use this exe in a laptop that has no parallel port.
So i bought a USB to parallel converter and installed in laptop.

But this converter is not getting detected with my exe.
There in software exe for reading from parallel port i gave port address as 0x378.

What is the address i should give for this converter??

Any ideas??Plz share...

Your information is not clear at all.
If you are not good with English, please use a free online translator to convert what you want to say from your language to English, and copy the result and paste it here.
I could translate my answers to your language as well, if you tell me which one you
use.

If you don't plug the adapter directly into a port built into the laptop it may not work correctly, and in that case the software for it may not install correctly.

Did you follow the installation directions?
e.g. you are often supposed to install the software for the device FIRST, then you plug in the device - the software installation may prompt you to plug in the device after it has installed all or most of the software.

0378 is the standard I/O address for LPT1
O278 is the standard I/O address for LPT2
etc.

0378 should be fine, since you say you have no parallel port on the laptop otherwise.

All of the standard I/O addresses for parallel ports are not used by anything else except other parallel ports.

What are you connecting to it?

A printer or scanner or a multifunction printer/scanner/etc. and most other parallel port connected devices require you set the parallel port mode to EPP, ECP, or EPP and ECP - usually EPP is fine.

Hello,

Let me explain in detail...
Actually i want to program a electronic chip through parallel port.
But my laptop doesnt have parallel port.
So i purchased a USB to Parallel port converter.

But this converter is unable to communicate with my chip programmer software.

Plz suggest..

You have not said so, but you must be plugging a chip programming device into the parallel port of the adapter.

See the documents or Help for the programming device and the USB to parallel adapter, or it's software, or look on the web site of the maker of the devices for trouble shooting information.

As I have said, most modern devices must have the parallel port mode set to EPP, ECP, or EPP and ECP mode. They won't work if that is set to SPP or Bidirectional mode.
.......

Unfortunately, there are many devices that will work fine connected to a regular parallel port that WILL NOT work with a USB to parallel adapter. A USB to parallel adapter should work fine with a printer, or probably a scanner, but it may NOT work with many other things.

They only way you can confrm whether you have that problem is to try connecting the chip programming device to a computer with a regular parallel port.
.......

If you want any further help, I need the make and model of
- the USB to parallel adapter
- the chip programming device.

What are you using to connect the chips to the BAFO adapter?

If the BAFO adapter is not being detected correctly in Windows.............

If it's not being seen at all, or if it is being detected but it has a problem in Device Manager

If you don't plug the adapter directly into a port built into the laptop it may not work correctly, and in that case the software for it may not install correctly.
See response 3 in this:
http://www.computing.net/answers/wi...

The BAFO manual for your adapter.
It's just instructions for how to install it properly in various operating systems.
This may also be on a CD that came with the adapter.
This is a direct link to the download.......
http://www.bafo.com/download/2007_d...

Make sure you have followed the instructions correctly.
If you're not sure whether you did, un-install anything listed for it in Add/Remove programs and install it again the proper way, according to the instructions for the operating system you are installing it in.

"But this converter is not getting detected with my exe."

"....i use ISP(in system programming) software of Asim Khan;s..."

If the BAFO adapter is being detected in Windows fine, but the problem is your programming software does not find it,
according to the above manual, apparently the BAFO adapter software may be using the standard I/O address for LPT2, which is 0278, or another I/O address other than 0378.

That makes sense, since a mboard that already has a parallel port is usually using the standard I/O address for LPT1 - 0378 , if the BAFO adapter used 0378 it would conflict with the other parallel port, and some people buy a USB to parallel adapter to add a second parallel port even if they already have a parallel port.

You can find out which I/O address the BAFO adapter is using by double clicking on the entry for the adapter in Device Manager, choose the Resources tab, and the I/O address it is using is listed there.
It may have it's own entry, and/or it's Resources may be listed only under Ports - LPTx.
Use whatever I/O address that is, in the configuration of your ISP software.

If the ISP software has a setting for the parallel port mode, it must be set to EPP, ECP, or EPP and ECP - usually EPP is fine.
.......

If finding the I/O address the BAFO adapter is using and using that in the programming software configuration does not help..........

According to the info at that link you supplied, the BAFO adapter cable can be used for:
"...printers, scanners, external CDROM drives, tape backups and webcams....."

According to research I did when a friend was thinking of using a USB to parallel adapter, unfortunately, there are many devices that will work fine connected to a regular parallel port that WILL NOT work with a USB to parallel adapter. Your BAFO USB to parallel adapter should work fine with " ...printers, scanners, external CDROM drives, tape backups and webcams...." but it may NOT work with many other things.

The only way you can confrm whether you have that problem is to try connecting whatever you are connecting to the parallel port on the BAFO adapter, to a regular parallel port on a computer that has a regular parallel port (you would use 0378 , and EPP or etc.., in the ISP software configuration in that case, or in any case whatever I/O address is listed in the Resources for LPTx under Ports in Device Manager) .

Yes mostly BAFO USB to Parallel adaptor works only for Printers , Scanner etc.


Current Scenario: Currently when i plug this adaptor, i see Windows XP detecting as new hardware found and when i go and check in the Device Manager section "a new device called " USB Printing Support" is added. But since this comes below the USB section in Device Manger.
This Doesn't have any address. ( like 378 ...)
I am expecting this device to be found under the PORTS section like " New LPT1 port" . Not sure whether there is really any way to do this.

Issue with adaptor or software ISP Software Tool is a Used for uploading Code to IC's.
Software is available from below sites
http://isp-programmer.software.info...

This software will try to detect a Parallel Port in the System.
But unfortunately software is not able to find as i am using a Laptop.

Now a days Laptops dont have Serial & Parallel ports. they come only with 3/4 USB ports,,but if i have any Parallel port supporting Hardware ,what should i do then ?

"Current Scenario: ....."

See the first part of response 6.

Windows must detect the BAFO adapter correctly.

I haven't used a USB to parallel adapter, so I don't know what you should see, but when I add a parallel port card, it's Resources are listed under Ports - LPTx , x being a different number than for the built into the mboard parallel port is using - I would think there should be a listing there if the software installed correctly.
.....

"This software will try to detect a Parallel Port in the System."

It will probably detect a standard parallel port in a system fine, but you may have to manually set settings for a USB to parallel adapter.
Or it may not be able to be used with a USB to parallel adapter at all, as I have already pointed out.
....

"...if i have any Parallel port supporting Hardware ,what should i do then ?..."

See the last paragraph in response 6
....

You still haven't told me how you're connecting the chips you're programming to the parallel port.
You may have to connect a chip in order for the ISP software to work.

My chip sits on DIP connector in the board with parallel port.
I am connecting my usb to parallel converter to that port.

what do you mean by connect chip in order??

"what do you mean by connect chip in order??"

You may have to connect a chip to the "DIP connector in the board with parallel port" to the parallel port on the BAFO adapter before you run the ISP software.

Yes..I am doing in the same way..
Connecting first and then running ISP software
