Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver
Attaching a Ground Wire to DXLink Transmitters/Receivers
Note:
Technically this type of grounding is only required when a DXLink Transmitter or Receiver is connected
to an ungrounded device, but this added grounding measure can be used at the discretion of the installer.
If the system is experiencing problems with delivery of DXLink signals to/from an Enova DGX Digital Media
Switcher or Enova DVX Solution, adding a ground wire from the TX/RX to the switcher may improve
performance. The problem is likely caused by the use of a single phase powered system that does not provide an
earth ground for a source or destination's chassis and shields. This can inject unnecessary AC voltage on the
HDMI cable shield that can lead to DXLink signal integrity issues. To check for indications of this type of power
in the system, look for a two pronged plug or a cord that has only two wires.
Items Required
Phillips #1 screwdriver
6 foot ground wire with ring terminal ends (provided)
Note:
Currently shipping DXLink Transmitters and Receivers provide a designated ground location on the
rear of the chassis for attaching a ground wire. For instructions on attaching a ground wire to DXLink Modules
without a designated ground location, see page 134.
Attaching a Ground Wire to a Common Earthed Ground
Connect the running end of the ground wire (fixed end attached to a DXLink Transmitter or Receiver) to a common
earthed ground (ideally, referenced to the Enova DGX Switcher or Enova DVX Solution).
Important:
If one DXLink Transmitter or Receiver is grounded, any remaining ungrounded units that are
connected to the same board on the Enova DGX Switcher must also be grounded.
Attaching Ground Wire to Module
Important
: Before attaching the ground wire to the chassis, ensure all connectors are clear.
To attach a ground wire to a module:
1.
If powered, power down the DXLink Module.
2.
Remove the designated ground screw and washer from the rear of the module.
3.
Secure the ring terminal of the ground wire against the chassis with the ground screw and washer.
