IP, which allows these products to be connected within a single system. Note that
HDCP content cannot be used when using these products in tandem.
• CAT-5 or CAT-6 cables should not exceed 330 feet (100 meters) between the
Sender / Receiver unit and the network.
• By default, all Sender and Receiver units are set to channel 0.
• This product does not support HDCP or dual link resolutions.
• By default, the source device will use the EDID from the display (or other sink device)
which is connected the Receiver unit. See EDID Management for more information.
• If terminating network cables in the eld, please adhere to the TIA/EIA568B
specication. See the Network Cable Diagram for details.
