Description:

This driver controls the Panasonic AE900 digital projector, a popular and inexpensive LCD video projector. The driver is PDL based.

Quirks and Limitations:

Though the projector's protocol is two way, it will not provide any information other than power status when the projector is off. So, if the driver comes up when the device is off, it will not provide reliable information until the projector has been powered on. In addition, the projector does not respond to commands when it is transitioning from power-off to power-on and vice versa. To accommodate this the standby field has been defined which is true whenever the projector is off or the projector is in a power transition state. You can use this field to 'wait on field' in your power on sequence so that you do not send commands that will not be processed.

Connection Details

The Panasonic AE900 provides serial control but does not provide a standard serial connector. Panasonic sells an adapter with part number ET-ADSER that converts this connector into a standard DB-9. The serial parameters are 9600,N,8,1.
