3.
Connect the black (
Tally
Out
) and red (
Contact
) pigtail wires as shown above. The number next to the Tally Out and
Contact pins must correspond to the video input on the switcher.
NOTES:
•
The drain wire does not need to be wired to the switcher. The Show Me cables are grounded via the video
connectors.
•
Do not connect the Show Me cable to the +V pin on the Extron switcher.
Press the
Share
button to switch the connected source to the main presentation display.
Pressing the
Share
button creates a momentary contact closure, which triggers the switcher to select the connected source
device. If a tally output is available, the button lights blue.
NOTES:
•
The source device provides the +5 VDC supply voltage needed to illuminate the
Share
button. If the source device
does not supply this +5 VDC, the
Share
button does not light. Some mobile devices do not provide the required
voltage to light up the button.
•
Digital Show Me cables support embedded audio and CEC signals.
