Interface Definition
One - out - Three Cable
The L2 has three terminals for its outlet, namely a DC3.5 - 1.35 power supply head (power port), an
RJ45 receptacle (network port), and a GH1.25 - 4Y plug (serial port). Users can connect to the L2
through the provided power adapter, serial port adapter module, data cable or network cable to
achieve power connection, control signal transmission and data transmission, etc., or they can also
customize and use materials suitable for the scene requirements to replace the adapter module to
improve the overall protection ability (such as dust and water resistance). The specification of the
serial port seat is GH1.25mm 4PIN.
The wire sequence definition of the L2 cable is as follows:
