The URA-232 is a video, audio and uni-directional RS-232 over UTP receiver. The receiver is located at a distance from the AV/RS-232 source and connected to a compatible UTP sender or extender. The URA-232 has a digital input configurable as contact or voltage. User defined serial strings can be sent depending on the state of the digital input and also remotely from a compatible UVA-232-4 or UVA-232-8 sender or via serial command. Using the remote capability, you can have URA-232 and URA-232-XT units daisy chained and talk to all the connected devices serially with each sending the same or completely different serial strings.
