“Show Me” Cables
The Extron “Show Me” cables are for use with Extron TeamWork systems. They feature a Share button for remote input source
selection and a control pigtail, which may be wired directly into Extron switchers with contact closure and tally outputs. The figure
below shows the HDMI “Show Me” cable, but all the “Show Me” cables have these same features (see the figure on page 2)

3. Connect the black (Tally Out), red (Contact In), and drain wire (ground) pigtail wires.
ATTENTION:
• The figure above illustrates how “Show Me” cables connect to the Extron MPS 601 switcher. The contact, tally out,
and ground connectors may be organized differently on your switcher. Ensure the port number for the contact, tally
out, and ground wires matches the video input port number. In the example above, the VGA connector is inserted into
Video Input 2 and the pigtail connectors are also connected to port 2.
• The video input must be grounded. For some switchers, the “Show Me” cables are grounded via the video
connectors. If this is not the case, it is necessary to connect the drain wire to the ground (G) connector.
• 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. Some mobile devices do not provide the required
voltage to light up the button.
• Digital “Show Me” cables support embedded audio and CEC signals.
Connect the Switcher to the Display Device
Connect the switcher HDMI output to the HDMI input of the display device, using the provided cable. Do not use HDMI to DVI
adapters. If necessary, see the user guide for the display device.
