Last year Smart-e announced the 4K-TX940, one of the very first true HDBaseT HDCP 2.2 splitters on the market. Now the company has followed up by releasing the 4K-TX941, an enhanced version of the 4K-TX940 that includes a powerful new addition – the ability to transmit RS232 signals through the same Cat 6 cable that distributes the 4K HDMI video signals.

In addition to all previous benefits provided by the 4K-TX940, including transmitting 4K UHD resolution HDMI signals over 100m of Cat 6 cable, four HDBaseT ports with POC and enhanced EDID management, the 4K-TX941 allows the source device to send RS232 signals to the displays providing a valuable method of remote control.

Communicating with displays using RS232 signals allows a user to remotely perform any action that the screen itself can perform. Smart-e says this gives a quick and easy solution to the various problems that often build up within screen installations over time.

All displays ultimately have a finite life-span, and whether they are negatively affected by screen burn, back light failure or projector lamp failure they will all eventually stop working. Using the 4K-TX941, a user can remotely deactivate as many screens as are not currently in use, thus extending their active use whilst saving power and the reducing the cost to the environment.

Additionally, accessible public displays can be manually interfered with, so it is important to check if the input channel or other settings have been altered. Using the RS232 function of the 4K-TX941 allows the control system to monitor the status of the display and change it back to the correct settings when necessary.

In addition to these more major benefits, the 4K-TX941 can be used to control screen features, including volume control and brightness. Connecting the RS232 to the 4K-TX941 is simple, using a three-pin screw terminal block which allows for the inevitable variation in cable pinout. 4K-RX904 receivers at the display end have the same connector providing ease of installation.

This HDCP 2.2 compliant 4K-TX941 compact unit is well suited for digital signage use in retail, houses of worship, education and transport infrastructure.

The 4K-TX940 is available direct from Smart-e and its distributor network. To assist with the installation process and technical queries, Smart-e is also providing dedicated product training sessions for installers. All Smart-e equipment comes with a three-year warranty and a high level of unlimited technical support.
