10.5. RS-232 Command Aransmission
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.

Bi-directional Control Data
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.

Bi-directional Control Data
The third-party control system is connected to the Lightware
crosspoint via a LAN connection to access all RS-232 remote ports.
Control commands can only be sent to and received from the matrix
on the LAN connection by the control system.
The baud rate can be 9600, 19200, 36800, 57600. There is a stop bit
and no parity bit covering all consumer devices on the market to be
suitable for the communication. The control protocol has two different
methods for sending and receiving RS-232 data from or to the frame:
ASCII mode could be used only with human readable characters while
binary mode can handle any data.
Maximum 54-byte data can be sent / received at once, e.g. it is not
possible to transfer files or to do a firmware upgrade via the router.
It is also important, that the control interfaces on the router (USB,
IP, and RS-232) use a shared resource. Please ensure that across all
connections no more than 8 unanswered queries are in progress. If
proper locking can not be implemented, waiting for 600 ms between
each query on each connections is generally sufficient.
