Mac driver for guc232a serial#
I don't rate it perfect because it is only a low-power version of a conventional serial port.ġ.

Drivers are supplied on CD for Win 98 SE but not for Linux.
It has stayed at COM5 for several cycles when left in the same USB port. However it may settle down when I'm through experimenting. It has also changed Comm port number upon restarting the computer. The GUC232A has a tendency to come back as a different Comm port each time you change USB ports. But with a sound card application, you won't ever need a Hamcom interface. Any op amp should get its supply somewhere else. You especially will not have enough current to use the CUG232A to drive a Hamcom interface, which uses 4 diodes to rectify certain RS-232 outputs to produce +&- 5 volts for a 741 op amp. After the resistor place a diode with cathode to ground.

In addition to using a Darlington optoisolator (ECG3045 in my case), I used a 1200-ohm resistor in series with the input LED. A single-transistor optoisolator will NOT turn on well enough. It is NOT satisfactory to drive LED optoisolators used in most homemade PTT interfaces UNLESS that optoisolator has a Darlington transistor. So it is NOT satisfactory with LED monitors in the serial line. It works with the Pakratt 232 TNC, which appears to have LSTTL buffers. It is quite satisfactory for equipment with buffered interfaces. The GUC232A puts out +&- 6 volts at low current-probably CMOS.
