Frequently Asked Questions - CHE-HDBT300U Comprehensive

What is the maximum transmission distance of the CHE-HDBT300U?

The CHE-HDBT300U can transmit signals up to 100 meters over Cat6 cable, and up to 70 meters over Cat5e cable at 4K resolution.

Does this receiver support 4K HDR content?

Yes, it supports 4K@60Hz 4:4:4 with HDR10 and Dolby Vision, provided the source and display are compatible.

Can I use it with a non-HDBaseT transmitter?

No, the CHE-HDBT300U is designed to work with HDBaseT Class A transmitters. For other types, a compatible transmitter is required.

How is the receiver powered?

It can be powered via Power over Ethernet (PoE 802.3af) from a compatible transmitter, or via the included 5V DC power adapter.

What cable type is recommended?

Use shielded Cat6 cable for best performance and to avoid interference. Cat5e may also work but limits distance and resolution.

Does it support audio return from the display?

No, the CHE-HDBT300U does not support ARC (Audio Return Channel). Audio is transmitted from source to display only.

How can I check if the connection is active?

The receiver has LED indicators: a green light for power, a yellow light for link status, and a blue light for signal activity.

What should I do if there is no picture?

First, check all cable connections and ensure the power LED is on. Verify that the transmitter is powered and compatible. If using PoE, make sure the transmitter supplies sufficient power. Also, try a different HDMI cable.

Can I daisy-chain multiple receivers?

No, the CHE-HDBT300U is a point-to-point receiver. It cannot be daisy-chained; you would need a matrix or splitter for multiple displays.

Is the device wall-mountable?

Yes, the metal enclosure has mounting holes for optional brackets (sold separately) to secure the unit behind a display or under a desk.
