F.C.S. (Frequency channel select) function supported
This is a function that allows for the selection of the frequency channel to be hopped to via frequency hopping. When the
frequency used by wireless LANs, AGVs, or other wireless devices is known, selecting a different frequency channel will allow
for hopping only to the selected frequency channel, thereby reducing communication collisions with other wireless devices and
stabilising communication.
∗ The number of selectable frequency channels varies depending on the country of use.
¡Countries other than the U.S., Canada, and South Korea: 5 to 79 ch ¡U.S., Canada, and South Korea: 15 to 79 ch
∗ If no channel is selected, hopping/communication is established on 79 ch by default.
Frequency hopping
Event communication system
A stable wireless environment is established using an
original protocol which is not affected by interference.
Interference from other wireless equipment is reduced.
Wireless communication is performed only when there
is a variation in the information, thereby suppressing
the frequency of radio wave output in wireless
communication and reducing interference with other
wireless devices.
