R, G, B and PSIG signal outputs.

The DC level is controlled to match the

SIG.C pin voltage.

Low output in power saving mode.

Analog 12.0V power supply.

R, G, B and PSIG output DC voltage

setting.

Connect a 0.01µF capacitor between

this pin and GND1.

When using a SIG.C of other than

Vcc2/2, input the SIG.C voltage from an

external source.

No connection.
