Microbrain Intelligent Technology ITS-AX2 - Power Supply Connection; Barrier Gate Control Signal

Here are the detailed connections of these
interface to the gate control board.
 Power supply connection:
The red wire("VCC") MUST be connected to the positive
output terminal of the 12V power supply,
The black wire ("GND") MUST be connected to the
negative output terminal of the power supply.
 Barrier gate control signal:
The green and blue wires are normally open signals 1 of
the radar onboard relay1.
The brown and purple wires are normally close signals 2
of the radar onboard relay.
The control line wires MUST be connected to the
originally loop detector interface and the public
common signal interface.
