Title
RS232 Documentation
Introduction: RS-232 is a communication protocol that can be used to send commands to and retrieve status information from projectors and other RS-232 enabled devices. Most commonly the RS-232 capability of projectors is used in conjunction with a control system capable of managing several other systems, such as lighting, curtains and audio systems, often via a touch panel remote. Simpler RS-232 implementations require nothing more than a personal computer, an RS-232 capable projector and the appropriate cable.
Configuration: Insert RS-232 configuration text here. Setting Bits per second (bps) Data bits Parity Stop Bits Flow control Emulation

NOTE 1: For ALL valid queries please wait 45 seconds after the power on sequence is run. If run before this timeframe a “Block item#” error will be sent through the serial port indicating invalid command. NOTE 2: Power query after a power on sequence will approximately 20 seconds then will report “On”.
