Synchronism function must be used to increase the robustness of the infrared barrier. It is enabled by removing jumper J2
from the RX and connecting the SINC (Synchronism) terminals of the RX and TX through a standard cable for alarm systems
(not supplied with the product).
Note:
if you are using a source to supply the TX and another to supply the RX, you must connect the GND of both sources for the synchronism
function to work correctly.
It is mandatory to use the Synchronization
function over distances greater than 60m or
environments with a high rate of fog or rain

In outdoor environments with a high rate of fog or rain, install the sensors at a maximum of
50% of the distance specified for each model, in order to avoid false alarms. In these places, it is
recommended to use the SYNC function
Sync cable to avoid false triggering.
