Model HR-731-S
6.0 Operation
The HR-731-S operates with a +5V power supply.
The HR-731-S has an input for HDMI source connection and a RS-232 port for
bi-directional data transmission between the Sender and the Receiver.
A fiber optic output connector is used to extend the HDMI signal to the Receiver
HR-733-R via a fiber optic cable up to 1000m.
The LINK LED will be on when there is an optic link between the Sender HR-
731-S and the Receiver HR-733-R. If no link is established between them, it will
be off.
The VIDEO LED will be on when there is a video source displayed on the sink
LCD.
The CEC and RS-232 LEDs are used to indicate the mode the data channel is set
to. By default they are in RS-232 mode. However, they can be switched to either
mode by sending a serial command ==>DCn to the Sender (see section
6.2).
