The child clock, as the name implies, is the child clock and the mother clock. The child clock is a time monitor hanging on the terminal, such as indoor or corridor, and the mother clock is a time source from the satellite / Internet. After the internal processing, the parent clock is sent to the user terminals through the switch, including Zi Zhong, computer, camera and other network devices.

Commissioning of master clock

The equipment is a standard 1U chassis, which can be installed in the standard cabinet by installing screws.

Insert one end of the power cord into the power supply unit of the device, then plug it in and then connect to the 220V power supply.

After confirming the error, press the switch of the equipment, the screen of the equipment is lit up, and the device is activated normally.

When the clock is normal, it is necessary to use the antenna to test whether the satellite can receive the satellite. If the satellite is not tested, the antenna will be changed to several places to try out the effect, so as to exclude the problem of antenna or satellite reception.

After receiving the satellite, the mother clock will display the number and working state of the current satellite, indicating that the master clock has been synchronized with the satellite successfully, and the current time is accurate.

There are 3 ways to login the device management interface:

The first is the direct connection of the computer, and the www.syn029.cn can be reached in the browser to reach the management interface.

The second is direct connection or through the switch, in the computer browser input the parent clock's original IP login to the management interface.

The third way is to login to the management interface through software.

After entering the management interface, you only need to change the IP and gateway, and the others need not be changed.

Debugging of sub clock

In order to avoid the product failure caused by the violent transportation of the sub clock, it is hoped that the user will receive a simple connection test after receiving the child clock to see if the display of the child clock is normal. If the display is normal, then the connection of the master clock will be made.

The power supply mode of sub clock is mostly 220V alternating current power supply, the power supply of sub clock is 2 220V power supply, and the physical interface is phoenix terminal.

The antenna used to receive the satellite time signal is a white mushroom antenna. It is called mushroom head antenna. In order to ensure the firmness and reliability of the antenna installation, we have mounting brackets and expansion screws in the antenna installation. We only need to place 3 fixed holes on the roof and then place them on the roof.

Lightning protection and rain protection measures

Because antennas should be erected in outdoor roofs / Windows / balconies / balconies and other places, attention should be paid to 1, lightning protection, the mushroom head rack on the roof / roof of the antenna, and it will inevitably be struck by lightning. Under normal circumstances, the use of lightning arrester can be avoided, connecting between the host and antenna, the interface is BNC, 2, rain proof, white mushroom head outer layer has already done waterproof and rain prevention measures. When installed, it can not be inverted and horizontally placed. It can only be vertical fixed. The only thing to pay attention to is that when the wiring is not allowed, the rain can not flow down the cable of the antenna. In the equipment, we need to make a U type waterproof.
