USER MANUAL
TCM 300 / 300C / 320 / 320C
A
TCM 300 provides operating modes for unidirectional (mode 0) and bidirectional (mode 1)
communication. In mode 0 all received radio messages are provided at the serial interface
as described in annex A.1. In mode 1 it is also possible to feed telegrams via the serial in-
terface into the module which will subsequently be transmitted. In addition control com-
mands can be sent and control messages can be received. This is described in annex A.2
and A.3.
A.1
When the module is in “Serial Interface” mode, it transfers out data blocks of information
from the received RF telegrams. As long as no transmitter has been learned, all received
EnOcean radio telegrams are transferred. As soon as at least one transmitter has been
learned only telegrams of transmitters learned by the receiver are transmitted via the serial
interface. Telegrams can be shown on the PC using EnOcean WinEtel or DolphinView soft-
ware.
A.1.1 Message format (ESP2)
The following figure shows the message format. A block is composed of 2 synchronization
bytes, 1 byte for the header and N bytes for the message data.
