PVS 405D • Connector Wiring 50
NOTE: Some projectors require NULL connection wiring, which inverts the Tx and Rx
connections. See the projector guide for details.
IR control for a connected input device such as a BluRay player can be made through the
PVT wallplate.
The connections between the MLC 104 IP Plus and the PVS 405D switcher should look
like the figure below.
