I have a prolifc USB to serial cable that I want to use to recieve infrared signals coming from a TSOP Sensor

I saw it is possible to connect a classic rs232 connector with TSOP here.

How can I connect it without damaging something ?


You most probably can't do that. The standard software for a TSOP-RS232 combo relies on the ability to read the hardware serial port very fast. An usb-to-serial cable does not offfer this option, it only offers a windows serial port interface, not the serial port hardware (register level) interface.

One option is to have a microcontroller read out the TSOP and send the decoded information to the PC, like shown here.
