Captive Screw

EDID

The captive screw connectors allow you to cut cables to a suitable length, reducing cable clutter 
while providing a more reliable connection.

Rondo has two EDID modes: Internal and Learn.
Internal mode selects the highest common resolution and audio between the source and all 
displays.

Note:

 4K, 3D, and multichannel audio are only available on internal mode if all displays are capable of it.

Learn mode selects the highest common resolution and audio betwen the source and output 1.
To switch between internal and learn modes, press and hold the EDID button. While EDID is being 
learned, the learn led will blink. EDID learn is complete when the EDID learn LED goes solid.

Connecting

The captive screw connectors have 
a contact bar that is adjusted to 
compress the wire against the top 
contact plate. Use the screws at the 
top of the connector to compress 
the wire against the contact plate.

When connecting the cables to the female captive screw connector it is important that the wires be 
terminated correctly. The female captive screw connector has a contact plate at the top and must 
have the wires touching it for signal to pass. When wired correctly 

(see picture A)

 the signal will pass, 

incorrectly 

(see picture B)

 no signal will pass.

Female captive screw connectors 
are included: Power
