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.
