Julian Time Set
The Set Time commands (D,H,M,S) will initialize the time in all counter modules. If a
particular counter has all Julian clock fields enabled the output string will have the
following inserted after the last A/D channel and before the CR/LF:
,DxxxHxxMxxSxx_xx
The x's would be ASCII characters (0-9) as required. The time registers are not incremented
until enabled with the 'J1xx' command, so they can be set up then synchronized by sending
the enable command at the correct time.
In Packed BCD and excess format the letters D,H,M,S, and _ are stripped and the data
encoded as per the Mag data above. The Day info is put into 2 bytes with the most
significant nibble of the most significant byte set to zero.
Julian Time Enable
This command starts/stops the Julian clock. To start the clock on counter 0 the command
would be "J100". "1" turns on the clock, while the "00" selects counter 0. To turn off the
clock update on counter 2 the command would be "J002".
