Terminal Description
pin 1: NC :IN: Not in use.
pin 2: NC : O : Not in use.
pin 3: POWER ON : O : Power ON signal output.
pin 4: AUS OUT : O : Video on signal output. When video manu-
al operation selection SW or Auto Select is
detected, High is output.
pin 5: CAM 2 OUT : O : The second camera on signal output. When
the second camera manual operation selec-
tion SW or Auto Select is detected, High is
output.
pin 6: CAM 1 OUT : O : The first camera on signal output. When the
first camera manual operation selection SW
or Auto Select is detected, High is output.
pin 7: DIMMER : O : Dimmer control signal output.
pin 8: EEP CS : O : The chip select signal output to the EEP-
ROM.
pin 9: VSS 0 : - : LED power ground.
pin 10: VDD 0 : - : Positive voltage supply.
pin 11: EEP DI :IN: The serial data input from the EEP-ROM.

pin 13: EEP CK : O : The clock pulse output to the EEP-ROM.
pin 14: SI :IN: Serial data input.
pin 15: OSD SO : O : The serial data output to the on screen dis-
play IC.
pin 16: OSD SCK : O : The clock pulse output to the on screen
display IC.
pin 17: OSD CS : O : The chip select signal output to the on
screen display IC.
pin 18: CAM 1 A IN :IN: The first camera Auto Select input. Active
Low.
pin 19: DIM A IN :IN: Dimmer signal input. Meanwhile, when this
terminal becomes Low when the first cam-
era, the second camera or the video has
been selected, the dimmer signal output ter-
minal becomes High.
pin 20: VDD : - : Positive voltage supply.
pin 21: A VSS : - : Negative voltage supply for analog section.
pin 22: CAM 2 A IN :IN: The second camera Auto Select input.
Active Low.
