Installation
4.4.2
Connections for DVI and RS-232 with real DVI
loopthrough
In this case, the master display or SET1 must be configured as master, the other
displays (SET2, 3 and 4) are to be configured as slave. The RS-232 data
transmission to the slave units is done by using the I²C EDID lines in the DVI
cable. See also the RS-232 DIP switch setting paragraph for the master/slave
configuration of the display.
