8.9.1. Input port status

Description: Shows the actual status of the input ports. The response length changes
regarding the frame size. The meaning of the values changes regarding the input board
types as the boards have different functions and capabilities.
Command {:ISD}
Response (ISD●<INPUT_D> )CrLf
Explanation: The first input board is a HDMI board. Input 1 and 2 have a connected
source but no signal. Inputs 3-5 have DVI signals and inputs 6-8 have HDMI signals. The
second input board is a DVI board. Input 11 and 12 have DVI signals. The Test Input port
has a HDMI signal.
Legend: <INPUT_D> may contain 9, 17, 33 or 80 hexadecimal numbers. Each number
represents the state for the corresponding input port. (The response characters are
grayed in eights for easier reading only.)
Port state sensing availability is differs with input board types. The meaning of the
responded number depends on the actual board type for that port. The binary
representation of the responded hexadecimal numbers is shown below.
