Appendix D – Cable Details and Pinout Info
Overview
The DXLink units; Multi-Format TX, HDMI TX, Wallplate TX, Decor Wallplate TX, and HDMI RX; all have
connectors for HDMI. The Multi-Format units 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 52.
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.
