External GPS Receiver#

An external GPS receiver with DCF code output, e.g. GNSS 4500, can be connected to the HN 61c.R Master clock as a source of synchronization signal (e.g. if a sufficiently long extension of the coaxial cable of the magnetic GPS antenna is not available).

  1. Place the external GPS receiver (e.g. GNSS 4500) to your desired location.

  2. Connect the cables from the GNSS 4500 receiver to the HN 61c.R terminals according to the image and connection table below:
