PYTHAGORAS 2
5 INFRARED ALIGNMENT AND CONFIGURATION
5.1 Channel Selection
To prevent interference by one barrier with another on the same site, barriers are equipped with
four selectable frequencies (channels).
The receiver and its associated transmitter must be configured with the same channel number.
This configuration is performed by using switches 3 & 4 on the control unit.
The channel is confirmed by the receiver and the transmitter when the barrier’s
power is turned on.
(Once the barrier’s power is turned on, the channel
selection switches have no effect when operated.)
The use of different channels allows installing several Newton barriers (max 4) without the need
of implementing sync. cables and without any type of reciprocal interference (optical
synchronism). The two examples shown in the Figure indicate how the use of different channels
allows installing several Newton barriers without their interfering with each other.
