Appendix D – Cable Details and Pinout Info
Overview
The DXLink devices, HDMI TX, Multi-Format TX, Wallplate TX, and HDMI RX, all have connectors
for HDMI. The Multi-Format devices have an additional port for HD-15 connectors.
The following table shows the video connections available on each of the DXLink devices.
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 44.
HDMI Connector Cable Pinout
HDMI connectors are found on the HDMI TX, the Multi-Format TX, the Wallplate TX, and the
HDMI RX DXLink modules. 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.
