Each GB60 black box can control up to two RA60 series radars. The system can also utilize more radars when several GB60s are networked. The RA60 is a dedicated GB60 radar series connecting directly to the GB60 black box via Ethernet. All the RA60 radar functions such as range, gain, rain & sea clutter and many more are controlled on the display via the KM60 keyboard or other GB60 dedicated operating units.
