RS-485 AHDC
™ Technology
Since RS-485 is bidirectional which means the driver is turned on only when it
needs to transmit some data, otherwise it is in floating mode. SUNIX
developed a new design to control the direction of driver (On or Off)
automatically which is called Auto Hardware Direction Control/Carrier Sense.
AHDC/CS
™ works on the same principle and only turns on the driver when
UART needs to
transmit some data; but the advantage is that AHDC/CS™.
Auto Hardware Direction Control (AHDC
™) technology makes it easier to
manage 2-wire RS-485 half-duplex communications, eliminating the need for
software interference. User does not necessary to write extra code for
Windows applications to control the half-duplex protocol. Auto Hardware
Direction Control (AHDC
™) technology is the key feature of SUNIX UART, and
this function is default enabling.
