The color of the cable for RJ45 connector meets the 568B standard:
1-orange and white, 2-orange, 3-green and white, 4-blue, 5-blue and
white, 6-green, 7-brown and white, and 8-brown.
The 1 and 3, 2 and 4 pins on the M12 interface are differentiated
signal pins in pairs. The orange-and-white and orange pair, green-
and-white and green pair, blue-and-white and blue pair, and brown-
and-white and brown pair in twist pair cables must be used in correct
pairs while being connected with the signal pins. For example, the
above figure, the orange-and-white and orange and green-and-
white and green pairs are used.
4.2 Grounding
Grounding protects the device from lightning and interference. Therefore, you
must ground the device properly. You need to ground the device before it is
powered on and disconnect the grounding cable after the device is powered
off. There is a grounding screw (see Figure 1) on the front panel of the device.
The screw is for chassis grounding. After crimping one end of the grounding
cable to a cold pressed terminal, secure the end of the grounding cable to the
grounding screw and firmly connect the other end to ground.
4.3 Power port
There is a power port on the front panel of the device. You need to connect the
power cable to the power port to provide power to the device. Power port is
equipped with M12 connector, which is dustproof, waterproof, and anti-
vibration. The device supports redundant power input, when one power input
is faulty, the device can continue operating properly, thereby improving
network reliability.
