1080p HDMI IP Transmitter

The SIIG CEH23B11S2 transmits 1080p video at 60 Hz with stereo audio over CAT5e or CAT6 cable up to 120 metres. It functions as an encoder in a scalable IP matrix that supports up to 256 total units with a limit of 100 transmitters. A matching decoder unit is required and sold separately.

Sustained matrix operation

The extender uses HDbit-T protocol with H.264 compression to maintain stable streaming across a dedicated IP network. Computer control software enables switching between multiple source devices without signal degradation during extended sessions. RS-232 pass-through provides continuous bidirectional device control alongside the video feed.

Build and daily connectivity

An HDMI output on the transmitter allows local monitoring of the source signal at the rack or desk. IR pass-back lets operators control the playback device from the remote display location using existing remotes. The unit integrates into rackmount or desktop workflows through standard HDMI, RJ45, RS-232 and IR ports.

Questions about this item

Does the CEH23B11S2 transmitter generate noticeable heat or fan noise when running continuously?

The unit has no fan and draws minimal power, so it runs silently with only slight warmth during all-day operation.

What other hardware must I already own to make this transmitter work?

You need the matching CE-H23C11-S2 decoder (RX), CAT5e or CAT6 cable up to 120 metres, and a dedicated IP network switch.

Will this extender integrate with my existing RS-232 controlled equipment?

Yes, the built-in RS-232 pass-through carries control signals in either direction alongside the HDMI stream.
