Note: No audio out, so volume control keys not supported. Freeze and mute toggle kbds supported. Use JED T461 for audio.
Note: Turn off auto-search.
Note: You must set baud rate to 19200 and enable RS232 in secret factory menu (see above). After exiting from the secret
menu, you MUST cycle 240VAC power. (not just projector standby. Pull the cord!)
Note: These projectors have a nasty hang-up habit, where coms just stops and only recovery is a 240v power cycle (i.e.
at the power point or by pulling the power plug. Until BenQ fix this, DO NOT INSTALL IT POWERED FROM A
CEILING POWER POINT. Instruct the user on how to “power cycle” the projector if it stops communicating.
