Rear Panel Features

  1. Secondary cellular (WWAN) antenna connector: This SMA female connector connects the router’s secondary cellular antenna. It is highly recommended to use the secondary antenna for diversity. In most circumstances, dual antennas will provide improved signal strength thus better performance.
  2. LAN 0 port: This RJ45 port connects the router to a 10/100 base-LAN. The port is autosensing for speed and wiring (straight-through or cross-over). LAN 0 port will used to configure the device.
  3. LAN 1 port (optional): not used
  4. Serial 0 port: RS232 serial port.
  5. Power cord input: This socket connects the router to a power source using either the supplied Power Supply or DC Power Cord. The barrel plug connector can be secured by rotating it by 90 degrees once installed into the DGPS-Box.
  6. Primary cellular (WWAN) antenna connector: This SMA female connector connects the router’s primary cellular antenna.
