Connecting the GPS Antenna

For instructions on how to install a GPS/GNSS antenna, the signal cable, and accessories such as surge protectors, weatherproofing kits, or amplifiers, refer to the Installation Guide that came with the respective equipment.

For additional information regarding the GPS antenna location selection, see Choosing a GNSS Antenna Location.

  1. Connect the GPS antenna to the GPS connector (see Rear Panel Overview, using the supplied Type-N adapter cable, and an LMR-400 equivalent cable with surge suppressor and active GPS L1 antenna, such as Spectracom model 8230.
  2. Note the GPS receiver connection provides 5VDC power for the antenna.

Establishing a Network Connection

  1. Connect a network cable to at least one of the Ethernet connectors ETH0 to ETH4 on the back panel of the unit. Take note of the ETH port you chose.
  2. Note: You'll likely want to change the default IP address of the ETH ports you plan on using. This procedure is described under Configuring IP Address(es). (You will need an Ethernet cable, or a serial null modem cable for this.)
