1 V-BOX Hardware Interface

Please ground during use(especially S and E series) to prevent hardware from being burned due to interference. If the vbox is installed in an electric control cabinet, make sure that the electric control cabinet is also grounded.

2、9-pin COM port: used to communicate with various PLC brands, servos, single-chip Microcomputer, instruments and meters on the market, and supports RS232/RS422/RS485. For specific interface definitions, please refer to the "V-Box Pin Definition" chapter.

35

3、Ethernet port: It can be used to connect to the network and communicate with HMI, various PLC brands, servos, single-chip Microcomputer, instruments and other equipment.

36

4、Antenna interface: 4G, WIFI antenna interface, used to enhance the signal.

37

5、IO contacts: H series comes standard with 2 relay outputs (DO) and 2 optocoupler isolation inputs (DI).

38

6、USB MINI interface: used for configuration debugging and Box configuration download.

7、Indicator light：

40

　　（1）Signal indicator: used to indicate the signal strength of WiFi/4G. When the SIM card status is abnormal, the signal cannot be detected or the signal is abnormal, the first grid of the signal indicator (signal light 1) will flash, and the other signal lights will be off.

41

　　The signal value of WiFi can be checked through the system register HSW146 of V-BOX, and the signal value of 2G/4G can be checked by the system register address HSW166.

42

　　①When 1<=signal value<=5: signal light 1 is always on;

43

　　②When 5 < signal value < 8:signal lights 1, 2 are always on;

44

　　③When 8<=signal value< 12: signal lights 1, 2, 3 are always on;

45

　　④When 12<=signal value: signal lights 1, 2, 3, 4 are always on.

46

　　（2）P/R light: V-Box operation indicator, this light flashes when V-Box is operating normally.Otherwise,V-Box firmware do not run well.

47

　　（3）NET light: network communication indicator. When the V-Box communicates with other devices through the network, this light flashes.

48

　　（4）LINK light: server connection indicator.

49

　　①When the V-BOX is not connected to the network, this light is off;

50

　　②When the V-BOX's network connection is normal, but not connected to the server, this light flashes;

51

　　③When the V-BOX's network connection is normal and the server is successfully connected, this light is always on.

52

　　（5）COM light: serial port communication indicator. When the V-BOX communicates with other devices through the serial port, this light flashes.

53

54

（6）4G signal range is 0-31 (usually needs to be greater than 20), WiFi signal range is 0-100 (usually needs to be greater than 80)

55

8、IO interface：

56

　　（1）Xn：Switch signal input terminal, with optocoupler isolation input.

57

　　（2）Yn：Switch signal output terminal, relay output.

58

　　（3）S/S：Input mode selection terminal, S/S connected with 24V+ means supporting NPN input mode; S/S connected with 24V- means supporting PNP input mode.

59

　　（4）COM：Output common.

60

9、RS485 communication terminal

61

　　（1）A+：RS485+ terminal.

62

　　（2）B-：RS485- terminal.

63

　　（3）GND：Common ground terminal of RS485 terminal.
