Smart Acknowledge

TCM 3x0 modules provide a post master function with 15 mail boxes for systems using

EnOcean smart acknowledge technology. This functionality is switched on in all operating

modes.

For detailed information on smart acknowledge please refer to the Smart Acknowledge sys-

tem specification.

When teaching-in a device using Smart Acknowledge please take care to switch off

all TCM 3x0 devices which are not continuously powered. Otherwise these TCM

3x0 modules could be declared postmaster. As soon as the power supply is

switched off a postmaster would be missing and Smart Acknowledge would not

work any longer!

Transmit timing

The setup of the transmission timing allows avoiding possible collisions with data packages

of other EnOcean transmitters as well as disturbances from the environment. With each

transmission cycle, 3 identical subtelegrams are transmitted within 40 ms. The transmis-

sion of a subtelegram lasts approximately 1.2 ms. The delay between the three transmis-

sion bursts is affected at random.
