a: Julian day
b: Hour
c: Minute
d: Second
e: Fractional Seconds (to 10 milliseconds)
If counter 0 had all clock fields selected for output except the Julian Day it
would modify the command string to "IJ:01111" followed with a carriage
return line feed.
Software Version Number:
The command "IV02" will command counter 2 to send its two character
software version number. Counter 2 would change the command string to
"IV02:xx" where xx is the version number of the software. If Counter 2 was
software version "A4" then the echoed command string would be
"IV02:A4" followed by a carriage return line feed.
Reset command:
If the command 'RESET' is sent to the counter a power up reset will occur
initializing all parameters to default. The reset sequence will not start until the
reset command has finished echoing out the RS232 port to the next
counter/logging device. This allows each device down the chain to reset in
sequence.
Update command:
If the command 'UPDATE' is sent to the counter, any parameters that were
changed, will be saved and be the default parameters the next time the system is
powered on. This command must be sent before powering down of the changes
will be lost.
Jump to debug:
If the command string 'XBUG' is received the counter will do a one way jump to
factory debug mode where a rudimentary operating system allows probing of
registers, ports and memory for debugging purposes. It will only function properly
with a single counter module (no daisy chained counters).
4.4.7 Power-up Initialization
By default all counters will wake up thinking that they are counter #0 and begin to
output data at the default 10 hertz rate or as set by default parameters in flash
memory. This data will appear as a synchronization command to subsequent
