3.7 Repeater configuration
TCM 3x0 provides the option to activate a one or two-level repeater for EnOcean radio tele-
grams.
1-level repeater: If a received telegram is a valid and original (not yet repeated), the tele-
gram is repeated after a random delay.
2-level repeater: If a received telegram is valid and original or repeated once, the telegram
is repeated after a random delay.
The repeated telegram is marked as “repeated” by an increased repeater counter.
Setting the repeater level:
At start-up of the module repeater on/off and repeater level are determined.
Please refer to the table in 3.2 regarding the configuration options.
The figure below shows the basic circuit for a stand-alone repeater.
2-level repeating function should only be activated if really needed! Otherwise the
system function can be compromised by collisions of telegrams.
Please note that in Mode 0 2-level repeating is not possible
(for backward compatibility to TCM 220C)!
