Repeater functionality
LED zone controller based on TCM 330 can provide repeater functionality.
Repeaters are used to extend radio range as they retransmit received telegrams after a
random delay. TCM 330 supports both first level repeating (repeating only original tele-
grams) and second level repeating (where telegrams from a first level repeater are repeat-
ed for a second time).
Repeating in general and second level repeating in particular should be used only if re-
quired based on careful planning as it significantly increases radio traffic and thereby the
likelihood of radio telegram collisions.
TCM 330 provides the option for Link-based Repeating where only such telegrams are re-
peated that originate from devices that TCM 330 is linked to. This Link-based Repeating
option is enabled by default and should be disabled only if required.
