Linx DVI 8x8 commands can be sent through the RS-232 port to control
the system.

•

The RS-232 port transfers commands using the asynchronous
serial protocol at 9600 to 115, 000 baud.

•

The port is configured as DCE and can handle full duplex
transfer.

•

Support for hardware and software handshaking is provided.
