Note 1 About the Mode switch depends on input bit number.

DVI output supports up to 8-bit. If the input signal has 9-bit or higher, the lower bit is assigned on the Dual Link side.

The mode switch should be set as below in that case.

2.5 Concerning the DDC power supply

The LVDS output of the IA-542-B provides the DDC power (+5V) supply. The maximum supply current of the DDC power supply is shown below.

● from AC adaptor … Max 500 mA

● from LVDS connector … Max 50 mA

DDC power supply is output as Fig. 2.5.1 shows.

+5V
