2.2 Plug-in check
⚫Step 1: Insert the TF card with firmware into the TF card slot on the side
⚫Step 2: Plug the 12V adapter into the power supply, the H68K will power itself on and
finish powering on
◼Step 3: Observe the blinking of the No. 1 indicator light. If it stops blinking after
about 20S of rapid blinking (stays on), the OP is on normally. If it is blinking
otherwise, it is Android mode etc. At the same time the prominent power button light
will light up warm white.
⚫Step 4: Use a network cable to interconnect the following network ports in turn to
confirm that the electrical interface of the device is normal.

1 Some other open source firmware may not have the same control over the lights, but being able to
light or blink is less of a problem.
2 The default built-in Android firmware is only boot TF card boot, which does not support
WIFI, so C D F does not support Android + WIFI firmware.
3 So m e TF cards (with burned firmware) are not compatible with H68K and will start up

abnormally, there will be no light flashing on the power on and the OP will not start up,
you need to change the card. The TF
card sent by default is supported.
⚫Step 5: Press and hold the protruding illuminated power button and after
approximately 5S, you can observe that the No. 1 light goes out and the power button light
goes out. The hibernation shutdown is complete.

2.3 Backstage access
⚫Step 1: Insert the card, power on and self-start, wait until the No. 1 indicator light
turns on, then the H68K OP mode is successfully powered on.
◼Step 2: Connect one end of the cable to the H68K ETH1 and the other end to the PC
network port; H68K ETH0 is the WAN port and ETH1 2 3 is the LAN port. The PC PC
needs to be set to DHCP mode (as shown below).
◼Step 3: Type 192.168.100.1 into your computer's browser, enter and the login screen
will pop up. Note that some open source firmware

2.4 Broadband dial-up routing and network allocation
methods
●The C D version is recommended for the first level of routing to the home network,
in the weak box, without WIFI.
2.4.1 Device connection topology diagram
2.4.2 Distribution methods
●Step 1: Connect the wire sequence
Connect the wire sequence as shown in the topology diagram above. Connect the incoming
optical cat or incoming network port to ETH0 (WAN port).
●Step 2: Back Office Login
The H68K waits for a successful power-up, the PC PC cable is connected to the ETH1 (LAN
port) and the H68K is wired to access the H68K backend.
●Step 3: Set up PPPOE dialing
Click on the [Network] button, click on the [Interface] button and click on [Modify] at the
WAN port
