Connecting the GNSS Input

  1. Install the GNSS antenna, surge suppressor, antenna cabling, and GNSS preamplifier (if required). Refer to the documentation included with the GNSS antenna for additional information regarding GNSS antenna installation.
  2. Connect the GNSS cable to the rear panel antenna input jack.
    In the event that NO antenna is connected to the rear panel jack, NetClock will—once it gets powered up (see Powering Up the Unit)—activate the Antenna Problem alarm, causing the front panel “Fault” light to be blinking orange (the Antenna Problem alarm indicates an open or short exists in the antenna cable.)
    Unless there is an open or short in the antenna cable, the "Fault" light should stop flashing orange once the GNSS antenna and coax cable are connected to the rear panel. If the "Fault" light does not stop flashing after connecting the antenna, refer to Troubleshooting GNSS Reception.

Initial synchronization with GNSS input may take up to 5 minutes (approximately) when used in the default stationary GNSS operating mode. If using GNSS, verify that GNSS is the synchronization source by navigating to MANAGEMENT > OTHER: Reference Priority: Confirm that GNSS is Enabled, and its Status for TIME and 1PPS is valid (green).
