3.2.1 GPIO supply voltage - IOVDD

For digital communication with other circuitry the pins of the serial interface UART may be operated from supply voltages different from DVDD. Therefore an interface voltage supply pin IOVDD is available which must be connected either to DVDD or to an external supply within the tolerated voltage range of IOVDD.

If DVDD=0 V (e.g. in any sleep mode or if VDD<VOFF) and IOVDD is supplied, there may be unpredictable and varying current from IOVDD caused by internal floating nodes. It must be taken care that the current into IOVDD does not exceed 10 mA while DVDD=0 V. If DVDD=0 V and IOVDD is not supplied, do not apply voltage to any above mentioned pin. This may lead to unpredictable malfunction of the device.

IOVDD voltage must not exceed VDD voltage! A malfunction of the module may be caused by such inverse supply!

USER MANUAL V1.2

TCM 310 / TCM 310C / TCM 310U

3.7 Built-in Repeater

TCM 310x provides the option to activate a one or two-level repeater for EnOcean radio telegrams.

1-level repeater: If a received telegram is a valid and original (not yet repeated), the telegram is repeated after a random delay. This delay will be chosen such that the maximum TX maturity time (as standardized in ISO 14543-3-10) of 40ms will not be exceeded.

2-level repeater: If a received telegram is valid and original or repeated once, the telegram is repeated after a random delay. This delay will be chosen such that the maximum TX maturity time (as standardized in ISO 14543-3-10) of 40ms will not be exceeded.

Repeated telegrams are marked as “repeated” by an increased repeater counter. Configuration of the repeater functionality is done via serial interface commands.

For detailed recommendations regarding the usage of repeaters please refer to our application note EnOcean Wireless Systems - Installation Notes (PDF), 09/2010.

TCM310x also provides selective repeating. It is possible to add filters and these will be applied during repeating. Selective repeating can be done based on:

 Sender ID  Destination ID  RORG  dBm value

It is possible to define white lists or black lists for selective repeating and for filtering of received radio telegrams passed via ESP3 independently.

All configuration values set via ESP3 commands are held in RAM and will therefore be lost after RESET or after a deep sleep phase. Only Smart Ack mailboxes are stored in FLASH and are available also after RESET or a deep sleep phase.

After sending a CO_WR_RESET command, the following CO_READY event indicates wake up reason 06 meaning ”A memory request from the CPU core does not

correspond to any valid memory location.” This is caused by the real reset cause

used when CO_WR_RESET will be performed. It is not a SW/HW malfunction. When using repeaters, care must be taken to ensure that regulatory transmitter duty cycle limits (if applicable) are not exceeded.

2-level repeating function should only be activated after careful study of the radio conditions! Otherwise the system function can be compromised by collisions of telegrams.

USER MANUAL V1.2

TCM 310 / TCM 310C / TCM 310U

3.8 Smart Acknowledge

TCM 310x provides a post master function with 20 mailboxes for sensors using Smart Acknowledge technology. For more information on smart acknowledge please refer to the EnOcean End Equipment Profiles (EEP) 2.6 specification.

When teaching-in a device using Smart Acknowledge please take care to switch off all TCM 3xy devices which are not continuously powered. Otherwise these TCM 3xy modules could be declared postmaster. If power supply to such postmaster will be switched off then Smart Acknowledge would not work due to the absence of the postmaster.

Smart Ack radio telegrams will be received and internally processed (post master, mailbox, etc.). There is no forwarding of such telegrams to the serial ESP3 interface.

3.9 Remote Management

TCM 310x provides a transparent radio channel also for remote management messages with a message length of up to 256 bytes. This enables an external micro controller connected to TCM 310 to handle remote management request from external devices or to control other devices via remote management.

For more information on remote management please refer to the EnOcean End Equipment Profiles (EEP) 2.5 specification.

4 APPLICATIONS INFORMATION

4.1 Transmission range

The main factors that influence the system transmission range are type and location of the antennas of the receiver and the transmitter, type of terrain and degree of obstruction of the link path, sources of interference affecting the receiver, and “dead” spots caused by signal reflections from nearby conductive objects. Since the expected transmission range strongly depends on this system conditions, range tests should categorically be performed before notification of a particular range that will be attainable by a certain application.

The following figures for expected transmission range are considered by using a PTM, a STM or a TCM radio transmitter device and the TCM radio receiver device with preinstalled whip antenna and may be used as a rough guide only:

 Line-of-sight connections: Typically 30 m range in corridors, up to 100 m in halls  Plasterboard walls / dry wood: Typically 30 m range, through max. 5 walls  Line-of-sight connections: Typically 30 m range in corridors, up to 100 m in halls  Ferro concrete walls / ceilings: Typically 10 m range, through max. 1 ceiling  Fire-safety walls, elevator shafts, staircases and supply areas should be considered as

screening.

The angle at which the transmitted signal hits the wall is very important. The effective wall thickness – and with it the signal attenuation – varies according to this angle. Signals should be transmitted as directly as possible through the wall. Wall niches should be avoided. Other factors restricting transmission range:

 Devices mounted on metal surfaces (shielding and detuning of antenna may cause heavy

loss of transmission range)

 Hollow lightweight walls filled with insulating wool on metal foil  Suspended ceilings with panels of metal or carbon fibre  Lead glass or glass with metal coating, steel furniture

The distance between EnOcean receivers and other transmitting devices such as computers, audio and video equipment that also emit high-frequency signals should be at least

0.5 m

A summarized application note to determine the transmission range within buildings is available as download from www.enocean.com.

4.4 Power supply requirements

In order to provide a good radio performance, great attention must be paid to the power supply and a correct layout and shielding. It is recommended to place a 22 µF ceramic capacitor between VDD and GND close to the module (material: X5R, X7R, min 6.3 V to avoid derating effects).

In addition, an HF SMD EMI Suppression Ferrite Bead such as the Würth WE-CBF HF SMD EMI Suppression Ferrite Bead (Würth order number 742863160) shall be inserted in the power supply line.

For best performance it is recommended to keep the ripple on the power supply rail below 10 mVpp (see 3.4).

All GND pins must be connected to GND. Be careful not to create loops! The ground must be realized ideally on both sides of the PCB board with many vias. At least there must be a short star connection. Otherwise RF performance can be reduced!

4.5 Layout recommendations

The length of lines connected to I/Os should not exceed 5 cm.

It is recommended to have a complete GND layer in the application PCB, at least in the area below the module and directly connected components (e.g. mid-layer of your application PCB).

Due to unisolated test points there are live signals accessible on the bottom side of the module.

Please follow the following advices to prevent interference with your application circuit:

 We suggest avoiding any copper structure in the area directly underneath

the module (top-layer layout of your application PCB). If this is not possible in your design, please provide coating on top of your PCB to prevent short circuits to the module. All bare metal surfaces including vias have to be covered (e.g. adequate layout of solder resist).

 It is mandatory that the area marked by the circle in the figure below is

kept clear of any conductive structures in the top layer and 0.3 mm below. Otherwise RF performance will be degraded!

Furthermore, any distortive signals (e.g. bus signals or power lines) should not be routed underneath the module. If such signals are present in your design, we suggest separating them by using a ground plane between module and these signal lines.

The data above are also available as EAGLE library.

In order to ensure good solder quality a solder mask thickness of 150 µm is recommended.

In case a 120 µm solder mask is used, it is recommended to enlarge the solder print. The pads on the solder print should then be 0.1 mm larger than the pad dimensions of the module as specified in chapter 2.3. (not relative to the above drawing).

Nevertheless an application and production specific test regarding the amount of soldering paste should be performed to find optimum parameters.

4.6 Soldering information

TCM 310x shall be soldered according to IPC/JEDEC J-STD-020C standard.

TCM 310 shall be handled according to Moisture Sensitivity Level MSL4 which means a floor time of 72 h. TCM 310 may be soldered only once, since one time is already consumed at production of the module itself.

Once the dry pack bag is opened, the desired quantity of units should be removed and the bag resealed within two hours. If the bag is left open longer than 30 minutes the desiccant should be replaced with dry desiccant. If devices have exceeded the specified floor life time of 72 h, they may be baked according IPC/JEDEC J-STD-033B at max. 90°C for less than 60 h.

Devices packaged in moisture-proof packaging should be stored in ambient conditions not exceeding temperatures of 40 °C or humidity levels of 90% r.H.

5 AGENCY CERTIFICATIONS

The modules have been tested to fulfil the approval requirements for CE (TCM 310) and FCC/IC (TCM 310C / TCM 310U) based on the built-in firmware.

5.1 CE approval

The modules bear the EC conformity marking CE and conform to the R&TTE EU-directive on radio equipment. The assembly conforms to the European and national requirements of electromagnetic compatibility.

The conformity has been proven and the according documentation has been deposited at EnOcean. The modules can be operated without notification and free of charge in the area of the European Union, and in Switzerland.

The following provisos apply:

 EnOcean RF modules must not be modified or used outside their specification limits.  EnOcean RF modules may only be used to transfer digital or digitized data. Analog

speech and/or music are not permitted.

 The final product incorporating EnOcean RF modules must itself meet the essential re-

quirement of the R&TTE Directive and a CE marking must be affixed on the final product and on the sales packaging each. Operating instructions containing a Declaration of Conformity has to be attached.

 If the transmitter is used according to the regulations of the 868.3 MHz band, a so-

called “Duty Cycle” of 1% per hour must not be exceeded. Permanent transmitters such as radio earphones are not allowed.

 The module must be used with only the following approved antenna(s):

Duty cycle lock for 868.3 MHz

In order to ensure the 1% duty cycle is not exceeded a watcher is implemented in firmware. This watcher limits the transmission of telegrams beyond the defined 1 % boundary.

USER MANUAL V1.2

TCM 310 / TCM 310C / TCM 310U

The EnOcean Duty cycle watcher implementation works as follows: the 60 minute regulatory interval is divided into 10 rolling time slots of equal length. For each of these time slots, the total transmission time is recorded. In addition to that, the transmission time in the current time slot is recorded. New telegrams will only be transmitted if the total transmission time in the previous 10 time slots (representing a full 60 minute interval), the transmission time in the current time slot, and the transmission time of the current telegram combined do not exceed the regulatory limit. The time slots are rotating, freeing always the last slot.

5.2 FCC (United States) Certification

TCM 310C / TCM 310U LIMITED MODULAR APPROVAL

This is an RF module approved for Limited Modular use operating as an intentional transmitting device with respect to 47 CFR 15.231(a-c) and is limited to OEM installation. The module is optimized to operate using small amounts of energy, and may be powered by a battery. The module transmits short radio packets comprised of control signals, (in some cases the control signal may be accompanied with data) such as those used with alarm systems, door openers, remote switches, and the like. The module does not support continuous streaming of voice, video, or any other forms of streaming data; it sends only short packets containing control signals and possibly data. The module is designed to comply with, has been tested according to 15.231(a-c), and has been found to comply with each requirement. Thus, a finished device containing the TCM 310C / TCM 310U radio module can be operated in the United States without additional Part 15 FCC approval (approval(s)

for unintentional radiators may be required for the OEM’s finished product), under EnO- cean’s FCC ID number. This greatly simplifies and shortens the design cycle and develop-

ment costs for OEM integrators. The module can be triggered manually or automatically, which cases are described below.

Manual Activation

The radio module can be configured to transmit a short packetized control signal if triggered manually. The module can be triggered, by pressing a switch, for example. The packet contains one (or more) control signals that is(are) intended to control something at the receiving end. The packet may also contain data. Depending on how much energy is available from the energy source, subsequent manual triggers can initiate the transmission of additional control signals. This may be necessary if prior packet(s) was(were) lost to fading or interference. Subsequent triggers can also be initiated as a pre-

caution if any doubt exists that the first packet didn’t arrive at the receiver. Each packet

that is transmitted, regardless of whether it was the first one or a subsequent one, will only be transmitted if enough energy is available from the energy source.

Automatic Activation

The radio module also can be configured to transmit a short packetized control signal if triggered automatically, by a relevant change of its inputs or in response to receiving a signal from another transmitter, for example. Again, the packet contains a control signal that is intended to control something at the receiving end and may also contain data. As above, it is possible for the packet to get lost and never reach the receiver. However, if enough energy is available from the energy source, and the module has been configured to do so, then another packet or packets containing the control signal may be transmitted at a later time. The device is capable to operate as a repeater, which can receive signals from the following list of FCC/IC approved transmitters, and retransmit the signals.
