D3.2.2 Operation Mode
The Field Wireless System supports one operation mode (Expert Mode) only.
When [Operation Mode] is selected in the menu tree in the left pane of the Configurator, the tab
shown in Figure D3-12 appears in the main window.

At this tab, [Expert Mode] is selected. No operations can be performed at this tab.
D3.2.3 Hopping Patterns
Field Wireless System uses the frequencies of 16 channels in the range of 2.4000 to 2.4835 GHz
as prescribed by IEEE802.15.4.
In order to coexist with other types of wireless systems using the same 2.4 GHz band, field wire-
less devices change wireless channels according to a prescribed order while transmitting.
This wireless channel order is called a hopping pattern.
When a Field Wireless System is comprised of several field wireless subnet and the wireless fre-
quencies overlap, changing the hopping pattern and preventing interference in the transmissions
of field wireless subnets provides stable transmission.
When [Hopping Patterns] is selected in the menu tree in the left pane of the Configurator, the tab
shown in Figure D3-13 appears in the main window.
