In order to comply with the industry standby low-power consumption requirements (regulatory ErP Lot 26 Tier 3), the WM408i projector requires an extra configuration for connecting it to a room controller such as Crestron® or Extron®.

For your projector to respond to your room control, try these steps:

1. Open the projector menu by pressing the menu button on the remote control (see the WM408i user manual to learn how to navigate the projector menu) 
2. Go to Settings
3. Set LAN (Standby) to ON
4. Go to LAN
5. Set DHCP to ON
6. Write down the IP and MAC addresses listed on the LAN page, and reserve the IP address (static) in your router/server
7. Open your room controller
8. Send a WoL command (AKA "magic packet") using the MAC address through UDP. The standard "ON" command through your room controller will not wake up the projector due to the low-power consumption requirements (regulatory ErP Lot 26 Tier 3).

9. Turn the projector on. The normal RS232 commands should work with the projector (see the WM408i user manual for these commands)

The WoL (magic packet) command must be issued every time a wake-on-LAN is triggered.

Using Wake On LAN (WoL) from a Crestron Control® system

System PCs that support "Wake-on-LAN" (WoL) functionality can be turned on by sending what is referred to as the "magic packet." This signal can be sent in a number of ways, including from a Crestron Control system.

Refer to https://en.wikipedia.org/wiki/Wake_on_lan for additional information on PC requirements and how to construct the magic packet. Also listed are resources to help configure a PC to respond to the Wake-on-LAN command.

Requirements for PC / Computer Wake On LAN (WoL) Functionality:

• The motherboard must support WoL
• NIC (Ethernet card) must support WoL
• BIOS/ OS must be configured properly to support WoL

For these reasons, not every computer can be guaranteed to work with WoL. WoL works only when setup correctly on computer hardware and software that support it.

How does WoL work?
A data packet is broadcast out on the Network to all devices – those with active listening will receive the packet. A PC supporting WoL will provide standby power to the onboard NIC card, which reads the MAC address 16 times as the trigger to wake.

Implementing WoL in SIMPL Programming for Nureva Wall

1. SIMPL Configure View – Add "UDP/IP Communications" symbol to Ethernet devices. Use Configure (F6) to specify the Computers IP Address, or use 255.255.255.255 (which will broadcast to the entire network)
2. SIMPL Program View – Send the magic packet as a serial string to the <TX$> of the UDP/IP Communication (typically Port 9 is used)
3. Depending on what PC hardware and OS is being used, different options will exist for turning it on from possibly different power off states such as standby or hibernate

Data in the magic packet is the defined constant as represented in hexadecimal: FF FF FF FF FF FF followed by sixteen repetitions of the target computer's MAC address, is also sometimes followed by a four or six-byte password.

NOTE:  The “Enable” signal on Crestron’s UDP/IP communications cannot be held high in the SIMPL Windows program. The signal must first be driven High prior to the WoL magic packet being transmitted and then driven Low immediately after the magic packet has been sent. Latching the enable signal High prevents UDP communication between the Crestron processor and the Nureva projector which is mitigated by the High/Low signal sequence.

NOTE: The UDP/IP Communications definition in the SIMPL Windows program requires a setting of the Subnet. For example, if the IP address of the Nureva projector was set to 192.168.0.100, a Subnet broadcast address of 192.168.0.255 must be used to allow the projector to receive the magic packet and Power On accordingly. 

NOTE: Windows 8, 8.1, and 10 will shut down a computer into what is called an S4 state, which can't be turned on via WoL. A description of this can be found on the Microsoft support site. In order for WoL from deep sleep (S4 or deeper) to work, both the BIOS and the NIC must support the "Wake from deep sleep" feature. Newer computers usually have the ability to disable S4+ states natively via BIOS. If the NIC does not support WoL from S4+, both the OS and the BIOS will need to be configured to disable S4+ states, otherwise, the BIOS will not allow for WoL even from S3>.
