Wake On LAN (WOL)

Wake-on-LAN (WOL) is an Ethernet networking standard that allows a computer to be turned on or woken up by a network message.

A Wake on LAN message can be generated in iViewer. This must be programmed through guiDesigner.

Make sure you have created a project in the Projects Tree.

In the System Manager, add a system. Configure it with the following properties:

• System Name: WOL (this can be whatever you want it to be known as)
• Protocol: UDP
• IP Address / Hostname: 255.255.255.255
• Port: 7 or 9 (either - try both if one doesn't work, this is dependant on your hardware being controlled)
• Port Origin: Set this to any port number above 1024. Lower port numbers might not be usable depending on the mobile platform you are running iViewer on.
• Leave all other settings as default
• Press OK

Next, we will use the WOL Generator to create the “Magic Packet” required to make the WOL command work.

To do this:

1. Click on View on the menu bar, then choose WOL Generator
2. Enter the MAC address of the device you want to wake up in the format 00-00-00-00-00-00
3. Make sure Hex Format is ticked
4. Click Generate Magic Packet

The WOL magic packet will be generated in the field below.

An example of a WOL magic packet:
\xFF\xFF\xFF\xFF\xFF\xFF\xAF\x45\xE4\x5A\xD3\x44\xAF\x45\xE4\x5A\xD3\x44\xAF\x45\xE4\x5A\xD3\x44\xAF\x45\xE4\x5A\xD3\x44\xAF\x45\xE4\x5A\xD3\x44\xAF\x45\xE4\x5A\xD3\x44\xAF\x45\xE4\x5A\xD3\x44\xAF\x45\xE4\x5A\xD3\x44\xAF\x45\xE4\x5A\xD3\x44\xAF\x45\xE4\x5A\xD3\x44\xAF\x45\xE4\x5A\xD3\x44\xAF\x45\xE4\x5A\xD3\x44\xAF

Now we need to create a command.
Add a command to the system you created earlier with the following properties:

• System: select the WOL system you created earlier
• Command Name: This can be a description of what you are waking, eg. Wake Media PC
• Command Value: Paste the WOL Magic Packet value here
• Click OK

You may now use this command as you would any other, eg:

• Add it to a button
• Add it as a startup command, so that whenever iViewer is launched it wakes up the device
