Adapter
The VoiceLift adapter is an RJ-45 to captive screw adapter cable assembly that is
used to connect the VoiceLift receiver with a PVS 204 SA PoleVault switcher. It
provides a means of connecting RJ-45 connectors with captive screw connectors,
enabling a plug-and-play connection from the receiver to the switcher.
The adapter also breaks out power from the PoleVault switcher’s MLC port to the
receiver, eliminating the need for a separate power supply.
