A few years ago I tried Extron’s DTP HDMI 4k TX (60-1271-12) to connect a classroom podium to a ceiling-mounted projector located in an auditorium. I was replacing older VGA technology and needed a solution that would allow for easy cabling options.
The Extron DTP HDMI 4K 230 Tx is a transmitter for sending HDMI, audio, and bidirectional RS‑232 and IR signals up to 230 feet (70 meters) over a shielded CATx cable to Extron DTP®‑enabled products. It provides an economical and effective means for extending HDMI with embedded multi-channel audio from HDMI-equipped devices. In addition, the DTP HDMI 4K 230 Tx accepts analog stereo audio signals for simultaneous transmission over the same shielded twisted pair cable. It supports video signals at resolutions up to 4K. The compact enclosure size and remote power capability make the DTP HDMI 4K 230 Tx ideal for discreet placement in lecterns, beneath tables, or wherever needed to meet application requirements.
I purchased the DTP transmitter and receiver and ran a cat6 cable from the podium to the projector. Connected both unit, and presto, the image was projecting on the screen. One of the fastest installs ever.
Now I will share with you a few tips I have picked up along the way.
Network cabling – while I have had success using non-Extron network cables, we had issues early on when we didn’t use Extron’s XTP DTP 24 Shielded Twisted Pair Cable. Sometimes you get what you pay for. Save time and just purchase a 1,000′ roll.
Power supplies – if you plan to use Extron’s DTP HDMI 4k TX (60-1271-12) in a stand-alone configuration, but sure your part number includes the power brick. If you are using the DTP 230 TX with some of the new IN1608 xi switchers, the DTP ports with supply the DTP 230TX with PoE.
If you ever have any questions about Extron technology for the classroom, please don’t hesitate to reach out to me. I’m happy to share my 15 years of experience using Extron technology and interactions with Extron professionals.
