Help JP1 with 9 pin serial D

uncle · Post by **uncle** » Thu Sep 02, 2004 4:22 am

I want to make a JP1 cable for my OFA 8060 but my computer has the 9 pin D serial connector. I know I could buy a converter but as I am making the cable from scratch it may as well be made witha 9 Pun D. Does any one have the instructions or could help me with the alternative connections for a 9 Pin Rather than a 25 pin.

This is my forst post and I am a newbie. Once I am up and running and gained more knowledge I hope to help others.

Do you want to build a Simple or serial interface?

Simple interface

Is there any advantage for going for anything else

The Simple interface connects to the parallel (printer) port and cannot use a 9-pin connector. That 9-pin connector on your PC is a serial port.

That explains it.

I assumed it was a serial interface. That could have been a right Shambles. I am an electronics engineer as well. (What do you mean not a very good one)

I will now build One and repost.

Cheers Mark for replying

Technically it is, but not RS232 serial. The serial communication with the EEPROM chip is doe with what is called "bit banging", which is manually turining bits on and off, and reading the bit status in software.
