Inverse Data Checksum (IDC) byte:
This byte will only be send if data length (LEN) is greater than 0. It is an 8 bit checksum of the data bytes (bytes 7 to
LEN+6) where a bit-wise inversion has been performed. The checksum is initialised to 0. The 8 bit sum (without carry) of
bytes 7 to LEN+7 is be 0xFF.
IDC = 0xFF – (DAT0+DAT1+DAT2+….), where only 8 bits are used
If a message checksum fails the controller will reply with the attention byte 0x15.
10. DDC/CI support
The monitor supports remote control by DDC/CI over DVI/DP (refer to 7.1 for pin assignments of the different
connectors). The DDC/CI uses the MCCS protocol, and we propose downloading the softMCCS software to get started and
learn more about this.
