4.4 Synchronisation
display
Correct function of the synchronization of multiple detectors is indicated by the scrolling effect of the LEDs in
an 8s rhythm. As the device address increases from left to right, the scrolling LEDs also run from left to right
for all synchronized detectors.
Polling of the Master detector is also possible, as described in 4.2 (M)ode button. The Master sends the
synchronization signals over the ribbon cable to the other detectors (Slaves). Selection is random.
4.5 DIP
switches
The 8-pole DIP switch is used for selecting the device address and for enabling termination for the CAN bus
and RS485 interface. The DIP switches are located inside the enclosure. As shipped all DIP switches are in
the OFF position.
