== Making a cable ==
In these modern days, few people have a true 12v RS232 interface anymore on their computer - many developers prefer to use USB to Serial adapters as they are much easier to interface without the need for level translator ICs as in previous designs.
FT232RL adapter boards such as [https://www.amazon.com/WWZMDiB-FT232RL-3-3V-5V-Converter-Adapter/dp/B0CCF3C1YF this] or [https://www.amazon.com/HUAREW-FT232RL-Converter-Adapter-Support/dp/B0CS3K6ZLS this] may be easily adapted by removing the 3.3v/5v jumper and soldering the VCC (sometimes labeled 3v3) pin on the end header to the VCC_2v5 or VCC_1v9 pin on the HPRM port to provide the proper voltage reference for RX and TX signals.
Some FT232RL adapter boards will have 3.3v / 5v solder bridge pads on the back of the board, in this case you'll need to cut the trace connecting to default voltage to the FT232RL voltage reference pin in order to use the PSP's voltage reference instead of removing a jumper.
In all, four wires should be soldered from the HPRM cable to the FT232RL adapter: RX, TX, VCC_1v9, and DGND as in the photo below. '''Be sure to connect PSP RX to FT232RL TX and PSP TX to FT232RL RX!'''
Please note that wire colors '''will not''' be the same from cable to cable, especially with third party cables
NOTE: the 3.3v / 5v voltage jumper on the FT232RL board '''MUST''' be removed or else '''damage to your PSP will occur'''!
