Application Diagrams


One to One Mode
Direct connection between the Transmitter and Receiver or through a Gigabit LAN via a dedicated gigabit switch hub.
One to Many Mode
Requires a dedicated Gigabit switch. If using an existing network, configure a VLAN to segregate the Transmitter and Receivers from other network traffic. Each VLAN can support only one Transmitter, but up to 253 Receivers.
Troubleshooting
- Display shows 'Please check the TX and RX connection': Verify power adapters are connected and the network cable is firmly plugged in.
- Display shows 'X' on Transmitter: Ensure the HDMI source is connected and powered on; try a different HDMI cable.
- Display shows 'X' between Transmitter & Receiver: Check the network cable connection and reseat the receiver's power adapter.
