Warning: This is the pin outs of the plug which we have made and successfully tested with our own software on our own PC's. You use this information at your own risk! It's easy to make a mistake and we take no responsibility for the potentially serious consequences. The serial port on IBM compatible PC's conform to the RS232 electrical standard and use a male DB-9 connector. (older PC's may use a DB-25 in which case a converter will be required). The DB-9 connector as the following 9 pins.
To make the loop back plug the following pins need to be connected together
This diagram shows the connections that need to be made. It's the rear view of the female DB-9 connector that's required for the plug. The red lines and gray dots show the connections that need to be made on the back of the plug. Female DB-9 connector - Rear view |
