EXCEPTION -
If an illegal data value is entered which is not listed above, then the Exception
Code 03 (Illegal Data Value) is returned.
NOTE
:
By grounding the RESET input during power-up cycle (approximately 10 seconds), the
FL3100H, and FL3101H Baud Rate will default to 19.2K.
5.7.13 Comm 1 Data Format (0CH)
A read returns the Comm 1 data format of the FL3100H / FL3101H. A write changes the data
format to the requested data format. After the data format has been changed to the addressed
unit, the Modbus communications may cease or start producing Comm errors because the data
format has changed; therefore the master will have to change its data format to the slave’s new
data format in order to restart or provide proper communications.

EXCEPTION -
If an illegal data value is entered which is not listed above, then the Exception
Code 03 (Illegal Data Value) is returned.
NOTE:
By grounding the RESET input during power-up cycle (approximately 10 seconds), the
FL3100H, and FL3101H Data Format will default to 8-N-1.
5.7.14 UV Signal Count (0DH)
A read indicates the number of UV Signal Counts that have occurred within 500 ms, which is
the time duration that is required to detect a fire in the UV spectrum.
5.7.15 IR Signal Count (0EH)
A read indicates the number of IR Signal Counts that have occurred within 500 ms which is the
time duration that is required to detect a fire in the IR spectrum.
5.7.16 UV Fault Total (0FH)
A read indicates the total number of UV COPM Faults for an indefinite period of time until the
Clear COPM Fault command is activated. The maximum count is 65535 and then the counter
will rollover to zero and begin counting again.
5.7.17 IR Fault Total (10H)
A read indicates total number of IR COPM Faults for an indefinite period of time until the Clear
COPM Fault command is activated. The maximum count is 65535
and then the counter rolls
back to zero and begins counting again.
