these pda's arent available anymore though .. so we need to switch ...
the software we use on the pda's (written by me so i could change it a bit) uses com1 (rs232 port)
the current pda's seem to use mini usb ... so i am now looking for a mini usb to rs232 converter .. which i cant find :(
i can find a lot of usb to rs232 converters (which i use in another project without any problems) ... but i couldnt find a pda with plain usb on it yet .. and i am not sure wether the driver for these usb-rs232 converter will work on windows mobile
