PYTHAGORAS 3
12 INFRARED ALIGNMENT AND CONFIGURATION
12.1 Channel Selection
To prevent interference by one barrier with another on the same site, barriers are equipped with
eight selectable frequencies (channels).
Each IR Optical Module 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 IR Optical Module:
Setting Channel M on both the groups as shown in the figure will not require the
connection of a synchronisation wire.
