Data Sheet - D e t a i l e d D e s c r i p t i o n
Serial 2-Wire Differential SSI Connection
With the addition of a RS-422 / RS-485 transceiver, a fully differential data transmission, according to the 21-bit SSI
interface standard is possible. To be compatible with this standard, the DCLK signal must be inverted. This is done by
reversing the Data+ and Data- lines of the transceiver.
Note: This type of transmission is read-only.
