The SP830/831 projector was fixed at 115,200 baud, and so needed to 460B baud rate converter. Code release 2.76A
allows for a new release of software (1.25 or later) in the projector to allow baud rate to be changed via the serial port.
You will need to connect to the projector via a D9 to 9-pin DIN connector cable and run HyperTerminal (or similar comms.
program) at115,200 baud. Type the command “X072X” (without the quotes). Then switch HyperTerminal to 19200, turn the
projector on manually, and verify that the command “X001X” turns the projector OFF. (Setting Flag0=1 can revert the coms to
38,400 to communicate with a 460b speed converter if one is installed.)
The projector lamp hours function and the Freeze functions do not work in the projector (with the current software), so the
Mute/Freeze keyboard is not supported. (This will be rechecked with the 1.25 release ... Ed)
The projector audio system, while it provides an audio input for each source, has control only of the internal speakers. There is
an audio output connector, but this is locked to ONLY the audio connectors associated with the D-SUB, at a fixed level. If
audio facilities are needed in an installation the T461 audio system MUST be used.
Aspect ratio setting is supported with dummy channels: “Set small4:3”, “Set reg 4:3” and “Set reg 16:9”.
