RS-232 Command Transmission
Lightware Hybrid Modular Matrix system provides bidirectional RS-232 signal transmission at remote
endpoints. The feature is implemented on certain boards like .... transmitters and receivers. The desired
third-party device can send and receive commands directly to/from the far endpoints. No additional cable is
required as the commands are sent through the cable (fiber, TPS) that is connected to the I/O board in the
matrix.
Lightware Hybrid Modular Matrix system provides easy interfacing of RS-232 control commands for devices
at remote endpoints through bidirectional RS-232 ports on the matrix I/O boards (MX-HDMI-OPT-IB, MX-
HDMI-OPT-OB, and MX-TPS-IB, MX-TPS-OB), transmitters and receivers. The desired application (e.g. control
system, touch screen) sends and receives short RS-232 control commands directly from the far endpoints.
The commands are sent out directly from the far endpoints independently on each optical or TPS port over
the same fiber or CATx cable, used by the video/audio transmission so that no additional cable is required
for system control.
Home Cinema Application
The RS-232 control command is transmitted from the touch control to the projector through the matrix and
the receiver on a single fiber, which also transmits the video and audio. The touch screen can control the
matrix as well to perform crosspoint-switching or change settings in the frame.
Conference Room Application
Both professional sources and displays can be controlled through the AV network. The touch screen control
sends a “presentation starting” command to the control system, which adjusts the lighting and shutters,
turns on the projector and switches the crosspoint’s output to the lectern laptop.
