This is the small control box that can wake up the PC using Wake On LAN. You can just push a button, PCs will wake up from the power off status. There is no need to start up another PC in order to start up a PC with Wake On Lan. Wake on LAN packets are sent via WiFi LAN. The Box has a battery, and you can charge it from a USB Type-C port. Once charging full, you can use it for a month. If any buttons are not pressed for the specified time (default 30 seconds), the box will sleep automatically and conserve battery power. Up to four PCs can be registered.
This box can send a Wake on LAN packet to the Wireless Access Point. To transfer the packet, the Access Point needs to be set to Bridge Mode. If Router Mode is set, the Access Point won't transfer to the wired LAN.
Quick Wake Up - Simply press one of the up, down, left, or right buttons to turn on the PC corresponding to that button. 4 PCs can be registered.
Microcontroller on board - No need for a PC when you turn on another PC. Directly send packets to the target PCs.
Transmit a packet via WiFi - Wake-on LAN packets are transmitted via Wireless Network.
Battery Powered - Using LiPo battery. It can run for a month (In this case, every day a few times used).
Small Handy Box - This box is only 60mm(W) x 23mm(H) x 80mm(D) size. No need for any cables, it works.
Configurable - Setting parameters are set from the display menu. SSID/Password/Target PC Hardware Address(4 PCs)/Time Zone/Sleep Time/Sleep Mode/Display Off Time/Reset Settings.
At first, you can set the WiFi SSID and PSK-Password. To set them, push the Center Key, you can see the setting menu, then select the WiFi using the UP or Down Key, and click the Center Key. Then, select SSID and enter your SSID of the Wireless Access point using the Up/Down/Left/Right key. After entering the SSID, push the center key, select yes using the Right key, then, push the Center key. Similarly, set the PSK-Password.
Next, set the Hardware Address(Ethernet MAC Address) of the PC that you want to wake up. Select HW Address and push Center Key, select from PC1 to PC4, push Center key, then enter your Hardware Address like 00:11:22:33:44:55.
After setting, just push button corresponding the target.(Up Key : PC1, Down Key : PC2, Left Key: PC3, Right Key: PC4)
To charge a battery, just connect to a USB Type-C port from the bus-powered USB port. During the charge, the CHG LED is RED ON. After the charging is full, the FUL LED is GREEN ON. And the charging will be stopped automatically.
