10.2 SYNCHRONIZATIONS

The barrier needs to be "synchronized" for proper functioning of the protection system and, in particular, to raise its security
level.
Synchronization is achieved through transmission of a "code" between barriers. This can be done in two modes: wired or
optical.
The advantage of optical synchronization is that it avoids having to run cables between the columns, as the code is
transmitted optically in the IR beam. However, consideration should be given to possible malfunctions due to the presence
of other infrared light sources (e.g. other IR barriers or photocells on gates).
During the design phase, it is advisable to include wired synchronization as it does not have this inconvenience.

IMPORTANT

USE OF BOTH TYPES OF SYNCHRONIZATION, OPTICAL AND WIRED, ON THE SAME SYSTEM IS
NOT PERMITTED.

The synchronizations should be connected as in the diagram above. Sync Out corresponds to the TX part of the column
and must be connected to Sync IN on the opposite RX column.

IMPORTANT The power supply negative must also have a common connection to the columns and shielded
cables (2x0.22) must be used for the synchronizations, preferably separated from the power supply, with the sheath
connected to the negative.
