Sales sheetFor bid packages
What is the maximum transmission distance?
The extender reaches 50M (164 ft.) at 4K@60Hz over a single Cat5e or Cat6 cable.
Why choose an ultra-slim extender for this application?
The 61 x 88 x 18mm ultra-slim TX/RX chassis suits tight rack or behind-display mounting where space is limited, while still delivering 18Gbps 4K@60Hz HDR performance to 50M.
How is the system wired end to end?
Connect the HDMI source to TX HDMI IN, run a single Cat5e/6 cable to RX RJ45 IN (up to 50M), and connect the remote display to RX HDMI OUT. RS-232 and IR pass-through allow control of source and display equipment from either end.
What is the maximum resolution and bandwidth of the EXT-50M18G?
The EXT-50M18G is HDMI 2.0 / HDCP 2.2 compliant with 18Gbps bandwidth, supporting 4K x 2K @ 60Hz (4:2:0) with HDR in 4:4:4 chroma.
How does the HDMI loop-out fit into a system?
The TX unit's HDMI OUT (Loop) port drives a local confidence monitor or secondary display simultaneously with the extended signal to the RX, operating independently of the RJ45 output.
How is RS-232 control passed through?
A DB9 connector on both TX and RX passes RS-232 signals bidirectionally between the source-end and display-end control systems.
What cable type is required?
The extender runs over a single Cat5e or Cat6 cable, STP recommended for best signal integrity at maximum distance; avoid running it parallel to power lines.
What are the unit dimensions and weight?
The ultra-slim TX and RX chassis measures 2.40 x 3.46 x 0.71 in (61 x 88 x 18mm); TX weighs 0.35 lb (160g) and RX weighs 0.34 lb (155g).
4K signal is degraded at maximum distance. What should I check?
Ensure STP (shielded twisted pair) Cat5e/6 cable is used, avoid running the cable parallel to power lines, check connectors for damage, and try reducing cable length.
The HDMI loop-out is not working. What should I check?
The loop-out operates independently of the RJ45 output. Confirm the HDMI cable from the TX loop-out to the local monitor is a Premium High Speed cable, and power-cycle the TX.
