Hi Marco,

it´s not only a cable adapter, but a Serial-to-parallel-convertor.
You can´t just solder some cable to a parallel connector.

Okay; I want to build me a platine having a RS232 port, fitting for the ActiveSync cable, and a parallel output as a normal PC has. Which ICs,batteries and other things do I have to use??

Go to eBay and look for the parallel printer cable for Jornada 6xx/7xx/820,
Part-No. F1274A. It´s the same for your 620 LX!
You can get it there for less money than building it from parts!

Since the failure of the LAN card, I do not want to buy any electronics on ebay anymore.

If I go to hardwarebook.net can I use those settings to make an adapter for a cable to connect my j720 to a serial keyboard? I know that there were special keyboards made for the 720 but have not been able to find them.
