1080p HDMI Extender Over IP

The SIIG CE-H23A11-S2 transmits 1080p video and stereo audio up to 120 metres over CAT5e or CAT6 cabling. It functions as a transmitter and receiver pair for point-to-point links or scalable matrix switching. Installers and AV integrators use it to bridge source devices and remote displays across structured wiring.

IR Pass-Back and Matrix Software

An IR pass-back channel lets users control the source from the display location without extra cabling. Included computer software manages input selection and switching across the matrix. The transmitter also provides a local HDMI output for confidence monitoring at the rack.

120-Metre CAT5e/6 Reach

The extender delivers 1080p at 60 Hz over a single UTP run of up to 120 metres. This distance ceiling determines whether the link fits the installation; longer runs require fibre or active repeaters not included here. Buyers needing greater reach must choose a different transport method.

Questions about this item

Will the CAT5e or CAT6 cables need periodic replacement for a 120m run?

UTP CAT5e or CAT6 cabling is rated for the full 120m distance; no scheduled cable replacement is required unless physical damage occurs.

What limits the number of transmitters when the matrix scales to 256 total units?

The system supports up to 256 total units but caps transmitters at 100; adding more receivers beyond that requires additional transmitter units (part CE-H23B11-S2).

How much power does each transmitter or receiver draw during all-day operation?

Each unit ships with a 5V 2A external power adapter, so maximum draw per transmitter or receiver is 10 watts under continuous use.
