The GPS 66 can use DifFerential GPS (DGPS) corrections in RTCM SC­
UM version 2.0 format, DGPS corrections in this format can be received
from an external device (capable of output in 6 of 8 byte format as
specified by RTCM SC-104, version 2.0) by connecting the device to the
input port on the back of the GPS 65 and selecting an RTCM input
interface mode. Two RTCM input modes are available, one which allows
