Does the AT-HD577 support 4K video?
Yes, it supports 4K UHD at 60 Hz with 4:4:4 chroma sampling, ensuring high-quality video with deep color.
Can the transmitter be powered from a compatible receiver?
Yes, the AT-HD577 supports Power over Ethernet (PoE) per IEEE 802.3af, so it can be powered by a PoE-compatible receiver, eliminating the need for a local power supply.
What type of cable is needed for HDBaseT transmission?
Use a shielded CAT6a cable (or better, such as CAT7) to achieve the maximum transmission distance and reliable performance. Standard CAT5e may work but with reduced distance.
Can I send IR and RS-232 signals along with video?
Yes, the AT-HD577 supports IR pass-through and RS-232 control via the HDBaseT link, allowing remote control of the source device from the display side.
Is the AT-HD577 HDCP 2.2 compliant?
Absolutely, the device is HDCP 2.2 compliant, which ensures compatibility with protected 4K content from streaming services and Blu-ray players.
What do the LED indicators on the AT-HD577 show?
The unit includes power and link LEDs. The power LED illuminates when the unit is powered, and the link LED indicates an active HDBaseT connection with the receiver.
Can I use an Ethernet switch between the transmitter and receiver?
No, the HDBaseT signal is point-to-point and cannot be routed through a standard network switch. The transmitter must be connected directly to the receiver.
How should I clean and maintain the transmitter?
Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or sprays. Keep the vents unobstructed to ensure proper cooling.
Is the AT-HD577 plug-and-play?
Yes, it is plug-and-play. Connect the HDMI source to the transmitter, the HDBaseT cable to the receiver, and power is automatically applied via PoE if the receiver supports it.
