Error 505 – Sender video connection not detected

Your sign’s controller is not properly connected to the sender card. This may be due to a disconnected cable, a faulty cable, or a faulty port on the sign controller.

With the power turned off to the sign, open the sign cabinet and check the connection between the sign controller and send card. Ensure that a secure connection is made between these two components. Depending on your sign model, this cable may be one of two types: HDMI to DVI, or DVI to DVI.

If this does not resolve the issue, contact support.
