HDMI over 2×RJ45 extender Cabletech ZLA0798 — AV signal extender up to 30 m

Cabletech ZLA0798 is an HDMI over 2×RJ45 extender designed to carry uncompressed HDMI audio-video signals over structured cabling up to 30 meters. The kit includes a transmitter and a receiver that connect to standard HDMI sources and displays, allowing installation where direct HDMI cable runs would be impractical. It transmits the AV signal via two RJ45 connectors, using commonly available Cat5e/Cat6 cabling to bridge longer distances while keeping device placement flexible.

Advantages

The extender supports straightforward point-to-point connection between a source and a display without requiring network switches, enabling reliable HDMI signal delivery over longer cable runs. Using two RJ45 ports improves signal integrity and compatibility with existing structured cabling. The compact transmitter and receiver units are suitable for wall-mounting or placement near devices, and the passive design simplifies setup with no complex configuration required.

Suitable for

• Connecting TVs and monitors located up to 30 m from an HDMI source
• Extending HDMI to projectors in meeting rooms and classrooms
• Integrating AV equipment in retail displays and digital signage
• Home theatre installations where HDMI cable runs are constrained

Key specifications

• Transmission medium: two RJ45 connectors over structured cabling (Cat5e/Cat6)
• Maximum recommended cable length: up to 30 meters
• Signal type: HDMI audio-video transmission (transmitter + receiver pair)
• Compatibility: standard HDMI sources and displays (TVs, monitors, projectors)
• Form factor: compact transmitter and receiver units for near-device placement

How to use

Connect the transmitter unit to the HDMI output of your source device and the receiver unit to the HDMI input of the display. Use two RJ45 cables between the transmitter and receiver, routed through existing structured cabling or direct patching, ensuring correct termination and good cable quality (Cat5e or Cat6 recommended). Power the units if external power is required, then select the appropriate HDMI input on the display. Verify resolution and audio settings on the source to match the display capabilities.

Usage recommendations

For reliable performance, use high-quality shielded Cat6 cabling and avoid routing near high-voltage lines or strong electromagnetic interference sources. Keep cable runs within the recommended 30 m for consistent image and audio quality. When installing in professional environments, test the link before final mounting and ensure connectors are securely terminated.
