What this product does

The Fosmon HD8239FLUS extends a single HDMI source over Cat5e, Cat6, Cat6a or Cat7 cable up to 164ft with Cat5e or Cat6 and up to 230ft with Cat6a or Cat7. It delivers 1080p at 60Hz video with HDMI 1.3 and HDCP 1.2 compliance and supports surround sound up to 7.1 channels for home, office or commercial installations.

Thermals noise and power

The unit operates from a single 5V 1A DC adapter connected to the transmitter only, using Power over Cable to supply the receiver without a second plug. No fans or active cooling are present, so the extender runs silently in normal use with negligible power draw.

When the jump is worth it

This replaces short HDMI runs that cannot reach distant displays or projectors, adding IR pass-through for remote control of the source device. It is not suited for buyers who need 4K resolution, HDR metadata or HDMI 2.0 bandwidth, and it does not support runs beyond 230ft without additional repeaters.

Questions about this item

How do I install the HD8239FLUS and what step is often missed?

Connect the transmitter to the source, run a shielded CAT6a or CAT7 cable up to 230ft to the receiver, plug the single 5V1A power supply into the transmitter only, then press the EQ button so the unit auto-adjusts for the cable length; the step most people skip is pressing that EQ button after power-up.

What maintenance or replacement will the HD8239FLUS need later?

The only field-replaceable parts are the 5V1A DC power adapter and the IR blaster or receiver cables; the transmitter and receiver units themselves have no user-serviceable components and require no periodic maintenance.

What limit appears first during sustained use of the HD8239FLUS?

The 165 MHz single-link bandwidth ceiling (4.95 Gbps) caps the signal at 1080p60, so the first hard limit you hit is resolution and refresh rate — higher resolutions or frame rates cannot be passed regardless of cable quality.
