The numbers in parenthesis ( ) are the extended characters if the year is sent to the Trackman in 4
digits vs 2.
For data sent to Trackman, the “SY3” command has been modified to allow 4-digit entry of the
year. The existing 2-digit year value remains valid also. If the system receives 4-digits within the
year field (before the trailing space character is received) it accepts the value with the following
rules applying. If the year is less than or equal to 1950 it assumes it is 20XX. If it is greater than
1950 then it assumes it is 19XX. If it receives only two digits that are less than or equal to 50 it
assumes it is 20XX. If it is greater than 50 then it assumes it is 19XX.
