Driver - GPS
Rx GPS
For use with a CP-21 GPS option board (superseded). Allows a Kingfisher RTU to determine its location and
synchronize its clock within 10 milliseconds of universal time anywhere in the world (GPS option board
required).
Comment: A 12-character description.
Device #: (1-249) Address assigned to the GPS option board. Data returned from the GPS option board is
stored in network registers corresponding to this address.
Update Freq (secs): (1-255, typically 1 sec) Setting determines how often the GPS option board sends the
new GPS data to the RTU.
Time Offset (mins): (0-1440) Enter the time offset to the Greenwich mean time of the local RTU. (eg.
Melbourne = GMT + 600 mins).
Synchronize Clock?: If ticked, the RTU real time clock is updated at the rate specified by the Update
Frequency above.
Dest. For Position: (#R1 to #R2043) Specified as a local register but indicates the first network register to
begin storing the position data from.
#Rx = degrees of latitude
#Fx+1 = float 0-59.999999 (6 decimal places) minutes of latitude
#Rx+3 = degrees of longitude
#Fx+4 = float 0-59.999999 (6 decimal places) minutes of longitude
Dest. For Time: (#R1 to #R2045) Specified as a local register but indicates the first network register to begin
storing the time data from.
#Rx = hours (0-23)
#Rx+1 = minutes (0-59)
#Fx+2 = float 0-59.999 seconds
Dest. For Altitude: (#R1, #R3 … #R2047 odd registers) Specified as a local register but indicates the
network float register to store the altitude data in. #Fx = float of altitude.
Dest. For #Satellites: (#R1 to #R2048) Specified as a local register but indicates the network register to
store the number of satellites data in. This is the number of satellites that are currently in contact with the
GPS option board.
Communicating With A GPS Option Board
When using a GPS option board the RTU should be configured as follows:
• First ensure that the GPS option board is supported by the type of RTU that is being used and that the
latest firmware is loaded in the RTU (as detailed in protocols.pdf available from www.cse-
semaphore.com/mykingfisher).
• Configure the port as follows (from Configuration, Port List): Type=GPS, Baud Rate=19200, Pre
TX=0ms, Post TX=0ms and Protocol=GPS.
• Add the configured Device address and port number of the GPS option board to the network list in
Configuration, Network List (this must be a unique address in the RTU network). Specify a Timeout of
2000ms.
• The GPS option board must be configured on the first ladder scan using the RX GPS block.
