VGA Over Cat5 Receiver For 150 m Runs

The StarTech ST121R receives a VGA signal sent over standard Cat5 twisted-pair cable at distances up to 150 m. It is built for installers who need to place displays far from the source in classrooms, lobbies or server rooms. No drivers or software are required, so deployment is a simple hardware connection.

Included Mounting Brackets And Power Adapter

The box supplies a 9 V DC power adapter and metal brackets for surface mounting the aluminum enclosure. These items let technicians secure the receiver near the display and power it from a local mains outlet without sourcing extra parts. The unit draws 0.6 A from the supplied adapter.

Resolution Drops As Cable Length Increases

At 50 m the extender supports 1600x1200, at 100 m it supports 1280x1024, and at the full 150 m it supports 1024x768. Buyers who need higher resolutions at the maximum distance cannot meet that requirement with this standard. Daisy-chaining and audio transmission are also not supported.

Questions sur cet article

How far can I run Cat5 cable before the 1024x768 image degrades?

The receiver supports 1024x768 at up to 150 m or 500 ft over Cat5 UTP or better cable.

What resolution drops first when the cable run approaches the maximum distance?

At 150 m the highest supported resolution is 1024x768; higher resolutions require shorter runs such as 1280x1024 at 100 m.

Does the aluminium enclosure stay cool enough for continuous 24-hour operation without a fan?

The passive aluminium housing dissipates heat from the low-power 9 V DC 0.6 A supply, so no active cooling is needed for all-day use.
