Like most people with modern PC’s I have no parallel port. I have a USB to 25pin parallel port adapter but I can’t get it to work. With this cable I have sucessfully connected an HP printer, however when I connect the JDM to it and then plug into a USB port no hardware is detected and I am not sure what driver to install.
Is there a generic USB to Parallel port driver that might work?
Anyone have any tips?
thank!
The JDM connects to the serial port (aka. COM port, RS232 port), typically a 9-pin male DSUB socket.
I don’t think a USB to serial adapter will work for JDM, as they probably do not generate the +/-12V on the Tx pin which is how JDM generates the programming voltage.
Luckily, my “modern PC” isn’t so modern that it doesn’t have a serial port.
oops my mistake! I meant to discuss the Pic Burner. I will move this to a different topic
Too slow 
In regards to the parallel port: I’m pretty sure all the parallel port to USB adapters are specifically meant for printers and their drivers only map it as a printer port and pretty much never as a general LPT.
