CP -21 GP S Op tio n Bo a rd
The GPS (Global Positioning System) option board is designed for use in a CP-21 and allows the RTU
to determine its location and synchronize its clock to universal time anywhere in the world. Location
and time information is obtained by connecting a GPS antenna to the option board SMB-F connector
which then allows the option board to communicate with nearby satellites.
