network cable up to 328 feet (100 m) in length. To ensure proper data transmission, use a Category 5e
STP cable or better.
1. Turn off the projector and HDBaseT transmitter.
Note: Make sure the projector and HDBaseT transmitter are turned off when connecting or
disconnecting a network cable between the two devices.
2. Connect one end of the network cable to the HDBaseTport on the transmitter.
3. Connect the other end to the projectors HDBaseTport.
