Bus Message Delay:
This command sets / displays the
minimum delay in 6.67ms units by
which the RS485 responses are
delayed.
0 = 0ms minimum delay
1 = 6.67ms minimum delay
2 = 13.33ms minimum delay
3 = 20ms minimum delay (default)
4 = 26.67ms minimum delay
5 = 33.33ms minimum delay
6 = 40ms minimum delay
7 = 46.67ms minimum delay
8 = 53.33ms minimum delay
9 = 60ms minimum delay
NOTE : In practise, the actual delay
can be upto 6.67ms longer than the
minimum due to processing times.

11.9.1 Operations Log Display Formats (OLG)
The Operations Log holds approximately 10,000 vehicle detect message entries if
the processor board is fitted with large RAM chips (667/1/26601/002). Only around
1,000 entries (less on PB681 firmware) can be recorded if the small RAM chips are
fitted (667/1/26601/001, now obsolete).
