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
eight selectable frequencies (channels).
Each Newton can be assigned to one of two groups, Group A or Group B, and each group can
be subdivided into 4 channels, channel M (Master), channel 1, channel 2 and channel 3. These
channels are set using the dip switches n°1, n°2 and n°3 located on the transmitter and
receiver, according to the schemes shown in the following table:
Associated transmitters and receivers must be configured with the same group/channel
number.
Example installations as follows:
1. Single Newton3:
Setting Channel M on both the groups as shown in the figure will not require the
connection of a synchronisation wire.
