SKU CH-BDJH-QTWZS MPN CEH27911S1

Splits one HDMI source to two Cat6-linked displays with loop-out, IR, ARC and RS-232 control

  • Splits one HDMI source to two displays over Cat6
  • Loop-out port passes the signal to a local monitor
  • IR emitter and receiver ports enable remote control forwarding
  • RS-232 terminal block allows serial device integration
  • ARC support returns audio from the display to the source

1×2 HDMI Splitter Over Cat6

The SIIG CEH27911S1 distributes one HDMI source to two remote displays over Cat6 cabling while keeping a local loop-out for a third screen. Built for meeting rooms, lecture halls, education sites, home theatres, restaurants, shopping centres, libraries and show rooms, it handles IR, RS-232 and S/PDIF alongside the video path.

Extends beyond standard cable reach

Replaces direct HDMI runs that hit distance limits or lack IR and audio return. The jump is worth it when the display sits farther than a passive cable allows, when you need IR control at the far end, or when a local monitor must stay active while the signal travels over structured wiring.

Maintains signal across the full Cat6 link

Under continuous operation the extender keeps video, IR, RS-232 and S/PDIF streams stable across the 12 V transmitter and 5 V receiver pair. Loop-out, IR emitters, IR receivers and serial control all remain active without drop-out during extended sessions in classrooms, venues or digital-signage installations.

Questions about this item

What rack or wall space does the CEH27911S1 transmitter and two receivers need for mounting?

The transmitter requires one 12V/2A DC jack and the two receivers each need a 5V/2A DC jack; all three units are compact desktop boxes that sit on a shelf or can be secured with Velcro or screws through their base slots.

Which cable connections must be made in the correct order to avoid a no-signal error on the CEH27911S1?

Connect Cat6 cables between the TX and both RX units first, then attach the HDMI source to the TX input and displays to the RX outputs, and finally apply power; powering up before the Cat6 links are seated often causes the extenders to miss the HDCP handshake.

When should the IR emitter and receiver cables on the CEH27911S1 be checked or replaced?

Inspect the 3.5mm IR cables if remote control becomes intermittent; dust or bent pins on the emitter/receiver plugs are the most common failure point and spare 3.5mm IR cables are inexpensive to swap in.
