Power
This system has three power supply interface, a power hub, a 5.08 terminal, pin 9 of the two
serial com (through the PCB jumper short circuit, default closed).
Power supply socket, outer diameter 5.5 mm inner 2.1 mm standard size, inside plus, outside
minus. The input voltage range 5 ~ 48
V,
current 150 MA. We default supply high quality 5 V / 1
A power adapter.
Power supply socket, the terminal and pin 9 of the com , mutual unicom, can choose one
power supply in, and another power supply out, better adapt to the use environment.

interface
It have 2 * RS232 interface. The serial port is male (needl), RS232 level (can be directly
connected to computer serial), part of RS232 pin sequences consistent to computer COM port.
When connected with the computer, we need to use cross cable (2-3 cross, 7-8 cross, 5-5 direct,
7-8 can don ’ t connect, but musn ’ t direcly connect to computer. Otherwise, it might lead to
irregularly work).
The DB9 interface contains the RS232, RS485 and RS422 interfaces.
