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 transmission medium.

When the cable of 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)

Output power of USB is up to 500mA per port, 1500mA in total.

RS232 does not support hardware handshake.
