Serial ports
QHY16803A provides two serial ports, which are connected to the built-in USB hub through FTDI
USB to Serial chip. These two serial ports provide standard RS232 signal level(

10V). You can use
it to connect your camera to electric focuser and even equatorial mount. But note that this signal
level is different from TTL signal level used in EQMOD. If you want to connect your camera to
equatorial mount through EQMOD, A signal level convertor between TTL and RS232 is needed.
After you finished installing the drivers, the serial ports drivers should also be installed. You can
