4.10.8 Options (0x0008)
A read returns the status of the settings for the Detector Sensitivity, Relay Delay, Relay
Latching/Non-Latching and Relay Energized/De-Energized features either from the Options
dipswitch or the FLASH depending on the setting of the dipswitch override bit listed above. A
write command changes the settings for the FLASH only when the dipswitch override bit is
enabled. The bits, 0-7 in the register, map directly to the dipswitches 1-8 as shown in Table 21.
NOTE:
If one writes to register 0x005B, the delay value will be changed, but bits 2 and 3 in
register 8 will not be affected. If register 0x0008 is then written to, it will reset register
0x005B if the bits are different from their previous values. If you intend to set the delay
through register 0x005B, bits 2 and 3 of register 0x0008 should always be written as
11.
EXCEPTION:
If an attempt to change the FLASH Options is made while the dipswitch
override bit is disabled, then the unit shall return an Exception Code 03 (Illegal Data
Value).
4.10.9
COM1 Address (0x0009)
A read command returns the current address for Com1. A write command changes the address
to the requested value. Valid addresses are 1-247 decimal.
Factory
default is
1
.
NOTE:
If the address is not in range an Illegal Data Value (03) is returned. By grounding the
RESET input during the first 1 second of the power up cycle, the FL4000 Address will
default to 1. The address will be set to a default of 1 when the red and green LED’s
flash alternately after approximately 1 second, at which time the RESET input can be
released from ground.
