Show Me Cables
The Extron “Show Me” cables are for use with Extron TeamWork systems. They feature a Share button for remote

and tally outputs.

3. Connect the Green (Tally Out) and Yellow (Contact) pigtail wires as shown above. The number under 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 will light up 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 +5VDC, the Share button will not illuminate. Many mobile devices do
not provide the required voltage to light up the button.
• Digital “Show Me” cables support embedded audio and CEC signals.
