NOTE
• This function can be used only when input is done with an analog RGB input module (ET-MD95RGB).
• This function enables switching only when receiving 480i in YCbCr mode. Switching cannot be done in
RGB REALITY mode, RGB mode, or when receiving signals other than 480i.
• The initial value is SMPTE.
Method of switching input impedance(signal level)for sync input
With analog RGB input, it is possible to switch the input impedance (signal level) of the sync signal. When
connecting with equipment (like a signal selector) whose sync output impedance is 75 ohm, use 75 ohm, and when
connection with equipment (like a PC video card) whose sync output is TTL, switch to TTL (HI-Z).

• This function can be used only when input is done with an analog RGB input module (ET-MD95RGB).
• Use by switching for each input signal.
• The initial value is 75 ohm.
• When this switching is performed, the CLOCK phase and image position may shift, so adjust again.
