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
Ω
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.
