10.4 Power mode transitions

Transition diagram

This diagram shows all modes available on the projector (ON, READY, ECO STANDBY), and the actions necessary to change mode.

SymbolDescription
Short pressing the Power on/off button on the local keypad or on the remote control unit.
Long pressing the Power on/off button on the local keypad or on the remote control unit.
Wake-On-LAN (WOL). Only works if a network was connected with the LAN port of the projector while the projector went to ECO STANDBY.
API command to change the power state of the projector (Power ON, Power OFF, Go to ECO).See Pulse user guide for more info (E.g. PJLink).
RS-232 ASCII command to Power ON the projector when in ECO STANDBY.
Auto light source off and auto standby features. Default disabled (factory settings). For configuration see power saving settings in the Pulse user guide.
The projector starts default up in READY mode when plugging in the power cord.
Wake-On-LAN (WOL)

Wake-On-LAN (WOL), the standard ethernet network command, can be used to awakened or to turn on the projector by network message.

Used alone, the WOL command allows to switch in READY mode. A JSON command must be performed in addition to make the projector turn in to ON mode:

  1. Send WOL.
  2. Wait for connection to façade/prospector (the unit does provide feedback when it’s ready).
  3. Wait for ready state.
  4. Sleep 5 seconds.
  5. Send JSON “power on” command (to switch in ON mode).
Note: Wake-On-LAN (WOL)

The link speed of the projector network interface in ECO mode is reduced to 10Mbit/s. This is standard practice in the industry to not waste power. Hence, the network connected with the projector must support such a low link speed to enable the remote wake up of the projector. This implies that all peripherals (switchers, routers...) in the network path must support WOL and configured correctly to support WOL.
