Dear Experts,

I have a visor pda , it is handspring visor pda . but i do not have the serial cable . so can anyone help me to make it, ..
nb. i discovered the following.....


The serial port on a Visor operates at TTL levels, not at RS232 – so if you want to connect to something that has a standard RS232 serial port, you’ll need a RS232 converter.  We have that in our serial cables for Visor, such as our PDCH-M9-6.

The pinout at the Visor connector is:
Pin 1 – Visor Rx
Pin 4 – GND
pin 8 – Visor Tx
These signals are at TTL level.


Thanks for your help
