4. Serial InterfaceYou can use the serial interface for three general purposes: querying the qik for information, setting itsconfiguration parameters,

Note: These lines are not compatible with RS-232 serial, which is inverted and uses voltages thatwould be out of spec (e.g. -12V to 12V). To connect t
