Model FL3102

EXCEPTION -

If an illegal data value is entered which is not listed above, then

the Exception Code 03 (Illegal Data Value) is returned.

EXCEPTION -

If an EEPROM write occurs, then the Exception Code 04 (Slave

Device Failure) is returned.

NOTE -

By grounding the RESET input during the first 10 seconds of the 2 -

minute power-up cycle, the FL3102 Baud Rate will default to 19.2K. The red and
green LED’s will flash simultaneously while the RESET input is grounded. The
Data Format will be set to a default of 8-N-1 when the red and green LED’s flash
alternately after approximately 10 seconds, at which time the RESET input can
be released from ground.

7.7.12 Comm 1 Data Format

A read returns the Comm 1 data format of the FL3102. 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.

This function is indicated on the Low Data Byte and the High Data Byte is not
used.

NOTE -

By grounding the RESET input during the first 10 seconds of the 2-

minute power-up cycle, the FL3102 Data Format will default to 8-N-1. The red
and green LED’s will flash simultaneously while the RESET input is grounded.
The Data Format will be set to a default of 8-N-1 when the red and green LED’s
flash alternately after approximately 10 seconds, at which time the RESET input
can be released from ground.

7.7.13 Fire Window COPM Fault Total (Photodiode)

A read indicates the number of Fire Channel Window COPM Faults that have
occurred in the slave device. This fault is usually caused by a dirty Fire Detector
Window. The maximum count is 255 and then the counter will roll over to zero
and begin counting again.
