were selected on counter 1 the echoed command string would be "AI01:100110" followed
with a carriage return line feed.
Julian Clock:
The command "IJ" will command counter 0 to output which Julian clock fields have been
selected for output (note that the two digit counter number was not specified, so counter 0
responds by default). Counter 0 will modify the command string to "IJ:abcde" where the
letters a-e would be replaced with an ASCII '0' (field off) or '1' (field on). The five output
fields are:
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.
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).
