How to switch the input impedance (signal level) of the synchronization signal
When the ET-MD95RGB input module (sold separately) is mounted, the user can switch the input impedance
(signal level) of the synchronization signal with the analog RGB input.
Choose 75 ohm when connecting with the equipment whose synchronization output impedance is 75 
Ω such as a
signal selector, or switch to HI-Z (TTL) when connecting with the equipment whose synchronization output is TTL
such as a video card of a PC.

• Switch the input impedance according to the input signal.
• The factory default is 75 
Ω.
• The clock phase and image position may become out of balance during this switching operation.
Please make readjustment accordingly.
