The 50g has a serial port. A simple cable makes it compatible with RS-232 levels.

Just to be clear on this subject, that simple cable will have to feature inside one "50G CMOS Digital Serial interface" to "RS232 interface" Converter, besides the cable wires and connectors that an even simpler cable would feature.

I agree it is simple, at least for anyone expert on electronics to build one properly, by converting the voltage and current levels on the Tx an RX lines and smart enough to not deplet the 50G batteries in the process.

I believe that is what Hpcalc have done, according to published information from the developer.
