Appendix G - Ground Wire Attachment Appendix G - Ground Wire Attachment Applicability This appendix covers attaching a ground wire to a DXLink Module without a designated ground location. If the module has a designated ground screw, see page 37. 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.
