V-BOX Hardware Interface

Hardware interface of V-BOX H series

Hardware interface of V-BOX S series

Hardware interface of V-BOX E series

V-BOX interface description

Power interface: DC24V power input 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.

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.

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.

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

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

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

Indicator light：

• Signal indicator: Except the P/R, NET, LINK, COM led light on right side, those 4 signal lights on the left side used to indicate the signal strength of WiFi/4G. Show like following picture:

  

  • Signal strength value of WiFi can be viewed by the internal register HSW146
  • Signal strength value of 4G can be viewed by the internal register HSW166
  • There are some different display for signal lights  means V-Box connection on different status:
    • 4 signal lights are keep off: Not recognize SIM card yet;
    • Signal light 1 (Counting from top to bottom) is blinking: SIM card status abnormal or signal abnormal;
    • 4 signal lights are blinking at the same time: Not able to connect with 4G base station;  
    • Signal light(s) is/are keep on which means the connection is OK;
• P/R light: V-Box operation indicator, this light flashes when V-Box is operating normally.Otherwise,V-Box firmware do not run well.
• NET light: network communication indicator. When the V-Box communicates with other devices through the network, this light flashes.
• LINK light: server connection indicator.
  • When the V-BOX is not connected to the network, this light is off;
  • When the V-BOX's network connection is normal, but not connected to the server, this light flashes;
  • When the V-BOX's network connection is normal and the server is successfully connected, this light is always on.
• COM light: serial port communication indicator. When the V-BOX communicates with other devices through the serial port, this light flashes.

IO interface：

• Xn: Switch signal input terminal, with optocoupler isolation input.
• Yn: Switch signal output terminal, relay output.
• 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.
• COM：Output common.

RS485 communication terminal

• A+: RS485+ terminal.
• B-: RS485- terminal.
• GND: Common ground terminal of RS485 terminal.
