Interfaces of Router V519

Hardware Interfaces

Front Side

  1. RJ45 Jack: LAN0 
  2. RJ45 Jack: LAN1
  3. DC Jack: DC7V~35V wide voltage, DC12V is better and recommended.
🧙Tips: 1) LAN0 can be used as WAN under regular router mode; 2) DC: 2.1mm Standard Round Interface, 7V~35V, Internal:+ (Positive), Outside: - (Negative).

Back Side

  1. 3G/4G/WIFI Antenna: SMA external rotation internal hole interface. 
  2. RESET: press for >5s when it’s powered on, SYS indicator will flash quickly and it’ll reboot. Then all settings will be reset to the default factory settings. 
  3. Serial Port: 4PIN PH2.0mm, GND/TX/RX/DC+ from left to right, DC+ can be used power supply to power on the router.
  4.  SIM card slot: Self-locking slot, press the white button on your left side and it will pop out.

Description for Serial Port

  1. From left to right: GND | TX | RX | DC+
Currently UART1 can only be used as RS232, it’s GND/TX/RX/DC+ from left to right. But for data transmission, only GND/TX/RX will be used, respectively connecting them to the 5PIN, 2PIN, 3PIN of computer’s serial port to establish serial communication. DC+ works as input and output connector of power supply. (E.g.: when input is 12V, then the output voltage is 12V too.)

Description for Antenna Port

There’re three SMA antenna ports, that is 3G/4G and 2x WiFi antenna ports. Users can select the appropriate antennas. Theoretically, the higher gain the antenna has, the better transmitting and receiving effect of WiFi it will be. For 3G/4G antenna, it’s recommended to use 3-5dB antenna. But for WiFi antenna, it depends on your requirement and coverage and supports max. 15dB.
