Troubleshooting:
1. Transmitter/Receiver boot time requires 30 seconds and will be able to be controlled after booting, The first reboot after
reset-to-default will be longer than 30 seconds.
2. We do not recommend using with existing LAN connections to avoid large video, data transmission or multicast packets
which will slow down your other LAN devices.
3. When using a Gigabit Ethernet switch it must support IGMP and Jumbo Frame over 8K in order to achieve the best
quality results.
4. If monitor shows green screen, check to see if the Ethernet switch is running under gigabit mode and if IGMP/Jumbo
Frame function in the Ethernet switch is enabled.
5. If the video is not smooth, please check if IGMP function is enabled or if the bandwidth of the switch is close to
maximum.
6. If the Ethernet cable is not connected it may cause unpredictable problems or OSD messages to error, please connect
the Ethernet connection and reboot.
7. Default EDID is 1080p with 7.1 audio. You can use Menu function 44 to copy EDID from the monitor of the Receiver.
8. If the monitor of the Receiver displays briefly then turns black but OSD shows properly, check that the HDCP version
supported by the monitor is adequate for the video source, and that the casting mode of Transmitter/Receiver are the
same and the HDCP setting is correct.
9. If receiver switches to a transmitter with no video input, it will show a blank screen or the last still image for a few
seconds.
10. Fast switch mode might cause the screen or audio to briefly behave abnormally when switching channels.
11. When output resolution is fixed, the screen or OSD might be cutoff a little if the source resolution is much different than
the receiver output (like 1080p downscale to 720p).
12. For high resolutions (like 1080p) the OSD response will be delayed a little bit.
13. In video wall mode, the OSD may not be in the correct size and position
14. RS232 only supports data transmission (TXD, RXD), it does not support hardware handshake (RTS, CTS, DTR,
DSR…)
15. When an AC adapter is used, that power has priority over power from PoE.
16. The front panel IR will be disabled when the external IR cable is plugged in.
17. If IR remote does not work properly, check the battery (especial in low temperature) and reset IR ID.
18. Audio in of Receiver only works in Unicast mode, and the audio in and audio out of Transmitter must be
connected.
19. Audio in of Receiver is designed for mono Mic In, not for stereo Line In.
20. When using a computer or mobile APP for management of the IP address, these devices should be set in same
subnet as the Transmitter/Receiver.
21. When TV wall setting parameters between APP/PC software and IR menu/Web are different they might conflict with
each other. We recommend setting a TV wall by one of two ways to prevent conflicts.
22. When using PC software and APPs, refer to their respective software operating instructions.
23. We do not recommend controlling by the front panel, computer software and APP at the same time as this can
cause conflicts.
