DualGroup is the function that divides all users of one Yapalong channel into 2 groups: group X and group O. The group arrangement is set by Binding procedure via 2C cable.
X unit can switch groups dynamically. A 2C Cable is needed for the switching. Toggle the 2C Switch on 2C Cable to switch groups. O unit cannot switch groups.
Since all communication happens on one channel, there is no adjacent channel interference (ACI).
Both Yapalong-5001 and 5002 have both functions of single group and DualGroup.
The number of total users cannot exceed 8. The number of users in either group is flexible. Yapalong-5001 is compatible with Yapalong-4000 or 5000, in single group or DualGroup. Yapalong-4000 or 5000 unit can only be bound as O unit.
The number of total users cannot exceed 12. The number of users in either group is flexible. Yapalong-5002 is only compatible with 5002 units, whether in single group or DualGroup.
