Wired Connection (HDMI Only)
The Unit can also be connected using the HDMI cable directly connected from the Tuner to the Display.
Both, the RF and the IR remote controls can be used to operate the unit.
The remote signal from the RF remote control is received by the Tuner Box and the IR signal from the IR
remote control is received by the Display Unit.
With the Display’s Main switch on, the TV can be turned on by:
Pressing the power switch on the RF remote control
Pressing the power switch on the IR remote control (Pointed at the Display Unit).
Pressing the power switch on the Tuner Box.
Note: Turning on the Display’s Main power switch, turns on the Tuner Box. Turning it off does not turn off
the Tuner Box. (This is true for wired or wireless connection).
CEC is a HDMI control feature that enables the Tuner Box and the Display Unit to control each other.
CEC stands for Consumer Electronics Control.
Based on a one-wire bidirectional system, the CEC line allows he Tuner and the Display to share a
communication channel.
The LVDS signal from the Global Core 6 (IC5100) and the sound data from the sound processor IC4510 in
the Tuner Box are applied to the LVDS transmitter in the DH board.
The CEC control signal from the GenX8 CEC System MPU (IC1500) and the LVDS data are transferred to
the Display Unit via the HDMI cable.
The TMDS data and the DDC-IIC are provided to an Equalizer circuit in the GH board to equalize the
signals encoded in the transition-minimized differential signaling (TMDS) format.
The Equalizer is used to compensate for signal decay and degradation due to cables and connectors.
The signal is then applied to IC24510 for processing.
