Null Modem Adapter |
This is an ordinary 9-pin null modem adapter. It is useful in conjunction with the HP 50g RS-232 serial cable to connect an HP 50g to a PC's serial port, or with two serial cables to connect two calculators together.
Because the 50g serial cable was intended primarily for communicating with other serial devices, this adapter is necessary to change the gender and swap the signal lines in order to communicate with a PC.
