Appendix D – Cable Details and Pinout Info
Overview
The DXLink units; DX-TX, HDMI TX, Wallplate TX, Decor Wallplate TX, and DX-RX; all have connectors for HDMI. DXLink Transmitters
(except the HDMI TX) have an additional port for HD-15 connectors.
The following table shows the video connections available on each of the DXLink units.
IMPORTANT:
System configurations will vary, necessitating different cable requirements for each system. Cables not available
through AMX should come from a trusted cable supplier.
NOTE:
When cabling video through either the HDMI port or HD-15 port, installers should be aware of how cabling will affect audio
signals. For information on audio precedence, see “Audio Type Precedence” on
page 41.
HDMI Connector Cable Pinout
HDMI connectors are found on all DXLink units. These connectors are used to pass HDMI or DVI-D signals (using a DVI-to-HDMI
cable adapter) from a source device to a DXLink Transmitter or from a DXLink Receiver to a destination device. The following table
provides cable pinout details for HDMI connections.
