Trouble Shooting

We strongly recommend using high-quality CAT5e, CAT6 UTP/STP/FTP cable. Improper installation may cause unstable connection, and video & audio interruption.
The highest data rate can be 850Mbps, which might affect other devices at the same LAN.
Either UTP or SFP can be used as a transmission medium.
When the cable of the external IR receiver connects to RX, the front panel IR will be disabled.
Analog audio of Rx (MIC IN) is mono sound for microphone only, not stereo audio (Line-in)
The output power of a USB is up to 500mA per port, 1500mA in total.
RS232 does not support hardware handshakes.
