For more details regarding I/Os please refer to Dolphin Core Description. 3.2.1 GPIO supply voltage - IOVDD For digital communication with other circuitry (peripherals) the digital I/O configured pins of the mixed signal sensor interface (ADIO0 to ADIO7) and the pins of the serial interface

(SCSEDIO0, SCLKDIO1, WSDADIO2, RSDADIO3) 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 men-

tioned pin. This may lead to unpredictable malfunction of the device. Inside TCM 320x the signals VDD and IOVDD are internally connected! Therefore the above mentioned issues have to be considered when writing own firmware 2013 EnOcean | www.enocean.com TCM 300x / TCM 320x User Manual | Page 14/53 USER MANUAL TCM 300 / TCM 300C / TCM 300U TCM 320 / TCM 320C / TCM 320U based on API. For I/O pins configured as analogue pins the IOVDD voltage level is not relevant!

However it is important to connect IOVDD to a supply voltage as specified in 3.4.

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. 2-level repeating function should only be activated if really needed! Otherwise the system function can be compromised by collisions of telegrams. 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. Please note that in Mode 0 2-level repeating is not possible

(for backward compatibility to TCM 220C)!

The figure below shows the basic circuit for a stand-alone repeater. 2013 EnOcean | www.enocean.com TCM 300x / TCM 320x User Manual | Page 18/53 USER MANUAL TCM 300 / TCM 300C / TCM 300U TCM 320 / TCM 320C / TCM 320U Teach-in procedure 3.8 Modes 1 to 4 support teach-in of transmitters. Please make sure not to remove supply voltage while in LRN mode! The flash con-

tent could get corrupted!

3.8.1 Setting the receiver to learning mode Via CLR Pin (ADIO4): Contact to GND longer than t = 2 seconds. Learning Mode LRN is entered after clearing ID memory. Via LRN Pin (ADIO3): Contact to GND longer than t = 0.5 seconds. In multi-channel receiver mode, the pin has to be contacted several times until the desired channel num-

ber is selected (the number of channels is given by the selected operating mode). Via Remote Config Control: Please refer to documentation of remote management. 3.8.2 Confirmation of Learning Mode Mode Confirmation 0 1 2 3 4 5 No Learn capability LMI HIGH continuously, LRN_TOGGLE toggling every 1 s. LMI HIGH continuously, CHANNEL0 toggling every 1 s. LMI HIGH continuously, current CHANNELx toggling every 1 s. LMI HIGH continuously, DIM IND HIGH, and PWM toggling every 1 s between 10% and 100%

Reserved for future use 3.8.3 Teaching in a transmitter In learning mode LRN, the sensitivity of the module is limited to in-room operations and learning of repeater powered signals is disabled (to avoid unintentional learning). Therefore ensure that the associated radio transmitter will be in a distance less than 5m to the re-

ceiver (not necessary within Remote Learn Mode). Trigger the telegram of the associated radio transmitter within 30 seconds:

Operate the switch radio transmitter (RPS or HRC) at least once (press I-button or O-

button of the rocker that is to be assigned to the selected receiver channel). If the same rocker is operated again within 4 seconds it will still be learned. If the same rocker is op-

erated again after more than 4 seconds it will be deleted again. Please note that teach-in without rocker information is not possible Please note that scene switches (HRC and last 3 ID bits 0B111) cannot be teach-in!

Or activate the sensor radio transmitter (1BS, 4BS) least once with active LRN bit

(DI_3=0, please refer to Standardization EnOcean Communication Profiles). If the same transmitter is operated again after more than 4 seconds with active LRN bit it will be deleted again. 2013 EnOcean | www.enocean.com TCM 300x / TCM 320x User Manual | Page 19/53 USER MANUAL TCM 300 / TCM 300C / TCM 300U TCM 320 / TCM 320C / TCM 320U Please note that in modes 2, 3, and 4 only RPS or HRC telegrams can be learned!

3.8.4 Confirmation of correct learning/deletion The output which is toggling every second while in teach-in mode (see above) will stay switched high for 4 seconds to signal that a transmitter has been learned. In case a trans-

mitter ID has been deleted it will stay 4 seconds low. 3.8.5 Learning of further transmitters After confirmation, the receiver changes again to readiness for learning. Further transmit-

ters can be learned immediately. If available the next receiver channel can be entered by connecting the LRN pin to GND longer than t = 0.5 seconds. A maximum of 30 radio transmitters can be learned (further attempts will be ignored; instead of learning confirma-

tion, operating mode is entered). Each rocker of a radio transmitter is counted as one transmitter. 3.8.6 Selecting the next channel By fresh contacting of the LRN pin to GND the next remaining channel is selected. In one-

channel mode or after the last channel, the operating mode is entered again. 3.8.7 Leaving learning mode LRN mode is left in either one of the following events:

Output of last available channel is toggling and a fresh contacting of the LRN pin to GND for 0.5 seconds is performed No ID has been added/deleted during the last 30 seconds. Memory was full and another ID was sent to be learnt 3.8.8 Deleting a transmitter Deletion of one specific transmitter: Use the same procedure as learning the associated transmitter. As transmitter delete confirmation, the corresponding function outputs remain in inactive state for 4 seconds while LMI keeps active. After that, a wrongly deleted transmitter can be learned again immediately. In order to delete a PTM transmitter the same rocker as during learn has to be operated. If several rockers of a PTM transmitter have been learned, all have to be deleted separately. Deletion of all learned transmitters: Connect the CLR pin longer than 2 seconds to GND All learned transmitters on all channels are deleted at the same time. After this, the re-

ceiver enters Learning Mode. 2013 EnOcean | www.enocean.com TCM 300x / TCM 320x User Manual | Page 20/53 USER MANUAL TCM 300 / TCM 300C / TCM 300U TCM 320 / TCM 320C / TCM 320U Remote management 3.9 TCM 3x0 supports the remote management specification which is available from EnOcean upon request.

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 3.11 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. 2013 EnOcean | www.enocean.com TCM 300x / TCM 320x User Manual | Page 22/53 USER MANUAL TCM 300 / TCM 300C / TCM 300U TCM 320 / TCM 320C / TCM 320U 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:

Switch mounted on metal surfaces (up to 30% loss of transmission range) Hollow lightweight walls filled with insulating wool on metal foil False 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 com-

puters, 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. 2013 EnOcean | www.enocean.com TCM 300x / TCM 320x User Manual | Page 23/53 USER MANUAL TCM 300 / TCM 300C / TCM 300U TCM 320 / TCM 320C / TCM 320U 4.2 Antenna options TCM 300x 4.2.1 Overview Several antenna types have been investigated by EnOcean.

Please take care to fix the antenna cable in case vibrations are expected. 2013 EnOcean | www.enocean.com TCM 300x / TCM 320x User Manual | Page 26/53 USER MANUAL TCM 300 / TCM 300C / TCM 300U TCM 320 / TCM 320C / TCM 320U 4.3.1 Positioning of the whip antenna Positioning and choice of receiver and transmitter antennas are the most important factors in determining system transmission range. For good receiver performance, great care must be taken about the space immediately around the antenna since this has a strong influence on screening and detuning the an-

tenna. The antenna should be drawn out as far as possible and must never be cut off. Mainly the far end of the wire should be mounted as far away as possible (at least 15 mm) from all metal parts, ground planes, PCB strip lines and fast logic components (e.g. micro-

processors). Do not roll up or twist the whip antenna!

Radio frequency hash from the motherboard desensitizes the receiver. Therefore:

PCB strip lines on the user board should be designed as short as possible A PCB ground plane layer with sufficient ground vias is strongly recommended See also section 4.5 for power supply requirements. Problems may especially occur with switching power supplies!

4.3.2 Mounting 50 antennas GND X remove TCM320C: X remove For mounting the receiver at bad RF locations (e.g. within a metal cabinet), an external 50 antenna may be connected. The whip antenna must be removed in this case!

TCM 320 provides soldering pads for an SMA connector, e.g. from Tyco Electronics:

Modification procedure:

TCM 320: Remove whip antenna and resistor, then mount SMA connector. TCM 320C: Remove whip antenna and 12 pF capacitor (see figure above). GND GND GND 50 Then mount SMA connector TCM 320U: Remove whip antenna and resistor, then mount SMA connector. 2013 EnOcean | www.enocean.com TCM 300x / TCM 320x User Manual | Page 27/53 USER MANUAL TCM 300 / TCM 300C / TCM 300U TCM 320 / TCM 320C / TCM 320U For 315 MHz and 902 MHz modules (TCM 320C and TCM 320U) please note that a full radio approval needs to be performed if modules are used with external antennas other than the pre-installed whip antenna. When using the SMA connector pads please make sure no mechanical forces are exerted on the 16-pin connector! It is recommended to use a strain relief for that purpose. 2013 EnOcean | www.enocean.com TCM 300x / TCM 320x User Manual | Page 28/53 USER MANUAL TCM 300 / TCM 300C / TCM 300U TCM 320 / TCM 320C / TCM 320U 4.4 Recommendations for laying a whip antenna PCB with GND PCB without GND Antenna too close to GND area 2013 EnOcean | www.enocean.com TCM 300x / TCM 320x User Manual | Page 29/53 Antennatoocloseto GND areaAntennaend ledback to footpoint USER MANUAL TCM 300 / TCM 300C / TCM 300U TCM 320 / TCM 320C / TCM 320U Power supply requirements 4.5 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 F ceramic ca-

pacitor between VDD and GND close to the module (material: X5R, X7R, min 6.3 V to avoid derating effects). In addition a 470 nH coil shall be inserted (Murata LQW18A, 0603) 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). 4.6 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!

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 0.3mm 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 RVDD line should be kept as short as possible.

Nevertheless an application and production specific test regarding the amount of soldering paste should be performed to find optimum parameters. 2013 EnOcean | www.enocean.com TCM 300x / TCM 320x User Manual | Page 33/53 USER MANUAL TCM 300 / TCM 300C / TCM 300U TCM 320 / TCM 320C / TCM 320U 4.7 Soldering information 4.7.1 TCM 300x TCM 300x has to be soldered according to IPC/JEDEC J-STD-020C standard. TCM 300x shall be handled according to Moisture Sensitivity Level MSL4 which means a floor time of 72 h. TCM 300 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. TCM 300x modules have to be soldered within 6 months after delivery!

74279266 (0603), 74279205 (0805) from Wrth. During radio transmission and reception only small currents may be drawn (I<100 A). Pulsed current drawn from RVDD has to be avoided. If pulsed currents are necessary, suffi-

cient blocking has to be provided. Voltage dips 4.11 The modules are supporting the handling of supply voltage dips (as requested e.g. by EN60669-2-1). As soon as the supply voltage drops below the VON3 threshold level the current consumption is reduced. TCM 300 will enter short term sleep mode (worst case 35 A), TCM 320 will enter standby mode (1.8 mA) for 200 ms. As long as the voltage at VDD does not drop below VOFF during that phase the module will restore the output state as set before the voltage dip. The minimal difference between VON and VOFF is 0.35 V. The electric charge needed to bridge this interval is:

1.8 mA x 200 ms = 360 C for TCM 320 0.035 mA x 200 ms = 7 C for TCM 300 This electric charge can be stored in an external capacitor. The required capacity (do not forget to add component specific tolerances and some extra margin) calculates as:

360 C / 0.35 V = 1028 F for TCM 320 7 C / 0.35 V = 20 F for TCM 300 If other external circuitry has to be supplied the calculations have to be done accordingly, using the total current consumption of module and external circuitry. 3 For a detailed definition of VON and VOFF please refer to Dolphin Core Description. 2013 EnOcean | www.enocean.com TCM 300x / TCM 320x User Manual | Page 36/53 USER MANUAL TCM 300 / TCM 300C / TCM 300U TCM 320 / TCM 320C / TCM 320U AGENCY CERTIFICATIONS 5 The modules have been tested to fulfil the approval requirements for CE (TCM 300 / TCM 320) and FCC/IC (TCM 300C / TCM 300U / TCM 320C / TCM 320U) based on the built-in firmware.

mentation has been deposited at EnOcean. The modules can be operated without notifica-

tion 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 es-

sential requirement 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 868.3.3 MHz band, a so-called Duty Cycle of 1% per hour must not be exceeded. Perma-

nent transmitters such as radio earphones are not allowed. The module must be used with only the following approved antenna(s). Type Parameter Value Wire/Monopole at RF_WHIP Maximum gain 1.0 dBi External antenna at RF_50 Antenna type Passive Impedance

mitting 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 sys-

tems, door openers, remote switches, and the like. The module does not support continu-

ous 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 300C / TCM 320C / TCM 300U /

TCM 320U 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 OEMs fin-

ished product), under EnOceans FCC ID number. This greatly simplifies and shortens the design cycle and development 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 trig-

gered 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 some-

thing at the receiving end. The packet may also contain data. Depending on how much en-

ergy 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 didnt 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. TCM 3x0C (315 MHz):

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 EnOcean serial protocol 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.

ence is in the H_SEQ code, TX_TELEGRAM is identified by 3. RX_Telegrams are identified by the H_SEQ codes according to table in A.1.3. Before sending commands via the serial interface please always wait for the re-

sponse to the previous command from the module. The reaction time is below 5ms. Be aware that an already received radio telegram might (concurrently to the command) be sent through the serial port before the command gets processed. A.2.1 Detailed description of ORG, DATA_BYTE, and STATUS fields Interoperability of different end-products based on EnOcean technology is an important success factor for establishment of the technology on the market. For this reason EnOcean Alliance pursues standardization of communication profiles, ensuring that sensors from one manufacturer can communicate with receiver gateways of another, for example. End-users thus have the entire product portfolio - enabled by EnOcean - at their disposal. And product manufacturers can focus on their own special field. Profiles of existing and upcoming types of equipment are defined in the following download document. Refer back to EnOcean Alliance about adding other profiles. http://www.enocean-alliance.org/en/enocean_standard/

A.3.1 ID Range commands Every TCM 300 supports a unique 32 bit ID and in addition a range of 128 IDs starting at an BaseID address. At production, every TCM 300 is programmed with a unique ID and a BaseID address. The BaseID number can be read via the serial interface. In order to allow a replacement of one unit with another unit (without having to go through the learning pro-

cedure with every receiver), the ID range can be changed via the serial interface. The allowed ID range is from 0xFF80_0000 to 0xFFFF_FFFE. 32 0 BaseID 25 most significant bits 0 0 0 0 0 0 0 0xFFFF_FFFF cannot be used. This address is reserved as broadcast ID.
