3.5 Control priority functions for lighting

and blind groups

Since one RXC controller can be assigned to a number of lighting or blind groups, each

with different group values, a method must be found to determine which group is to act

on the RXC controller. The diagram below highlights the problem on the basis of the

groupings illustrated earlier.

If, for example, a command applies to group Aop, this will transmit the command to the

associated RXC controllers, including RXC controllers 1, 2, 6 and 7. At the same time,

however, group AOx also acts on these controllers. How is this resolved?

RXC 1, 2, 6, 7

RXC 3..5, 8..10

&: Rules for bindings

The problem described above is solved as follows:

• Assign priorities to the blind and lighting groups.

• When a controller belongs to several groups of the same priority, the last command

always takes precedence.
