<h3>TCM</h3>
<ul>
  The TCM module serves an USB or TCP/IP connected TCM 120 or TCM 310x, TCM 410J, TCM 515
  EnOcean Transceiver module. These are mostly packaged together with a serial to USB
  chip and an antenna, e.g. the BSC BOR contains the TCM 120, the <a
  href="http://www.enocean.com/de/enocean_module/usb-300-oem/">USB 300</a> from
  EnOcean and the EUL from busware contains a TCM 310 or TCM 515. See also the datasheet
  available from <a href="http://www.enocean.com">www.enocean.com</a>.
  <br>
  As the TCM 120 and the TCM 310, TCM 410J, TCM 515 speak completely different protocols, this
  module implements 2 drivers in one. It is the "physical" part for the <a
  href="#EnOcean">EnOcean</a> module.<br><br>
  Please note that EnOcean repeaters also send Fhem data telegrams again. Use
  <code>attr &lt;name&gt; <a href="#blockSenderID">blockSenderID</a> own</code>
  to block receiving telegrams with TCM SenderIDs.<br>
  The address range used by your transceiver module, can be found in the
  parameters BaseID and LastID.
  <br><br>
  The transceiver moduls do not always support all commands. The supported range
  of commands depends on the hardware and the firmware version. A firmware update
  is usually not provided.
  <br><br>
  The TCM module enables also a wired connection to Eltako actuators over the
  Eltako RS485 bus in the switchboard or distribution box via Eltako FGW14 RS232-RS485
  gateway modules. These actuators are linked to an associated wireless antenna module
  (FAM14) on the bus. The FAM14 device frequently polls the actuator status of all
  associated devices if the FAM14 operating mode rotary switch is on position 4.
  Therefore, actuator states can be retrieved more reliable, even after any fhem downtime,
  when switch events or actuator confirmations could not have been tracked during the
  downtime. As all actuators are polled approx. every 1-2 seconds, it should be avoided to
  use event-on-update-reading. Use instead either event-on-change-reading or
  event-min-interval.
  The Eltako bus uses the EnOcean Serial Protocol version 2 (ESP2). For this reason,
  a FGW14 can be configured as a ESP2. The attribute <a href="#TCM_comType">comType</a>
  must be set to RS485.<br><br>

  <b>Define</b>
  <ul>
    <code>define &lt;name&gt; TCM [ESP2|ESP3] &lt;device&gt;</code> <br>
    <br>
    First you have to specify the type of the EnOcean Transceiver Chip, i.e
    either ESP2 for the TCM 120 or ESP3 for the TCM 310x, TCM 410J, TCM 515, USB 300, USB400J, USB 500.<br><br>
    <code>device</code> can take the same parameters (@baudrate, @directio,
    TCP/IP, none) like the <a href="#CULdefine">CUL</a>, but you probably have
    to specify the baudrate: the TCM 120 should be opened with 9600 Baud, the
    TCM 310 and TCM 515 with 57600 baud. For Eltako FGW14 devices, type has to be set to 120 and
    the baudrate has to be set to 57600 baud if the FGW14 operating mode
    rotary switch is on position 6.<br><br>

    Example:
    <ul><code>
      define BscBor TCM ESP2 /dev/ttyACM0@9600<br>
      define FGW14 TCM ESP2 /dev/ttyS3@57600<br>
      define TCM310 TCM ESP3 /dev/ttyACM0@57600<br>
      define TCM310 TCM ESP3 COM1@57600 (Windows)<br>
    </code></ul>
  </ul>
