Not connected Do not connect! 2.2.1 Interface 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 can 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 sleepmode) and IOVDD is supplied, there may be un-predictable 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. 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. In TCM 320/TCM 320C VDD is internally connected to IOVDD! Therefore the above mentioned issues have to be considered when writing own firmware based on API. IOVDD voltage must not exceed VDD voltage! A malfunction of the module may be caused by such inverse supply! For I/O pins configured as analog pins the IOVDD voltage level is not relevant!

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 2.2 regarding the configuration options. The figure below shows an example circuit for a repeater. 2-level repeating function should only be activated if really needed! Otherwise the system function can be compromised by collisions of telegrams. Please note that in Mode 0 2-level repeating is not possible (for backward compatibility to TCM 220C)!

Therefore ensure that the associated radio transmitter will be in a distance less than 5 m 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.

In case a trans-mitter ID has been deleted it will stay 4 seconds low. 2.8.5 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 trans-mitters can be learned (further attempts will be ignored; instead of learning confirmation, operating mode is entered). Each rocker of a radio transmitter is counted as one transmit-ter. 2.8.6 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. 2.8.7 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 2.8.8 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.

This functionality is switched on in all operating modes. For detailed information on smart acknowledge please refer to the Smart Acknowledge sys-tem specification. 2.11 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.
USER MANUAL V0.82 © 2010 EnOcean | www.enocean.com TCM 300 / 300C / 320 / 320C User Manual V0.82 | Page 20/43 TCM 300 / 300C / 320 / 320C 3 APPLICATIONS INFORMATION 3.1 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.

They all have advantages and disadvantages as shown in the following table. Advantages Disadvantages Whip Antenna (15 cm @ 315 MHz, 8.6 cm @ 868 MHz) Cheap Automatic placement difficult Omnidirectional Bending influences performance Large size Chip Antenna (AMD1103-ST01 @ 315 MHz/868 MHz) Omnidirectional Expensive Small size Very sensitive to environment (GND plane, components), minimum distance space to other components needed Automatic placement possible Splatch Antenna (ANT-315-SP1 @ 315 MHz, ANT-868-SP1 @ 868 MHz) Omnidirectional Expensive Not very sensitive to environment, low distance space to other components re-quired Large size Automatic placement possible Helical Antenna (ANT-315-HE @ 315 MHz) Omnidirectional Large distance space to other components required Cheap Large size (3D) Through hole component, no SMT 868 MHz modules used in Europe do not need additional approval if the external antenna fulfils the following requirements: Antenna type Passive Mandatory for radio approval Center Frequency 868.3 MHz Mandatory for radio approval Impedance ~50 Ohm Mandatory for radio approval Maximum gain ≤ 8 dBd Mandatory for radio approval VSWR ≤ 1.5:1 Important for compatibility with EnOcean protocol Return Loss > 14 dB Important for compatibility with EnOcean protocol Bandwidth ≤ 20 MHz Important if 10V/m EMC required for device

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 3.5 for power supply requirements. Problems may especially occur with switching power supplies! Specification of the TCM whip antenna; L=150 mm @ 315 MHz, L=86 mm @ 868 MHz

Please take care to fix the antenna cable in case vibrations are expected. 3.3.2 Mounting 50 Ω antennas For mounting the receiver at bad RF locations (e.g. within a metal cabinet), an external 50 Ω antenna may be connected. The whip antenna must be removed in this case! TCM 320 / 320C provide soldering pads for an SMA connector, e.g. from Tyco Electronics: Modification procedure:  TCM320: Remove whip antenna and mount SMA connector  TCM320C: Remove whip antenna and 12pF capacitor. Then mount SMA connector For 315 MHz modules (TCM 300C and TCM 320C) please note that a full approval is needed if modules are used with external antennas. 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. 50Ω GND GND GND GND X remove TCM320C: X remove

It is recommended to place a 22 µF 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. It is recommended to keep the ripple on the power supply rail below 10 mVpp (see 2.4). 3.6 Layout recommendations 3.6.1 TCM 300/300C recommended foot pattern Top layer

TCM 300 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. 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 300 modules have to be soldered within 6 months after delivery!

As long as no transmitter has been learned, all received EnOcean 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 inter-face. The data block format is explained later in this document; it depends on the type of sensor from which the telegram has been received. A.1.1 Message format 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. Message format for asynchronous serial communication A.1.2 Byte signals and bit order  9600 bps; 8 data bits, no parity bit, one start bit, one stop bit  Line idle is binary 1 (standard)  Each character has one start bit (binary 0), 8 information bits (least significant bit first) and one stop bit (binary 1) Signals and bit order sending a byte TxD Sync Header Byte0 ByteN-1 ...

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 0xFF800000 to 0xFFFFFFFF. In order to prevent misuse, this feature can only be used 10 times! Please note: The unique ID cannot be changed. Command (TCT) Response (RMT) SET_BASEID OK, ERR, ERR_IDRANGE RD_BASEID INF_BASEID A.3.2 Receiver sensitivity commands The receiver sensitivity can be changed by the following commands. In LOW sensitivity mode, only transmitters in the vicinity of the module are received. Command (TCT) Response (RMT) SET_RX_SENSITIVITY OK RD_RX_SENSITIVITY INF_RX_SENSITIVITY A.3.3 Reset command Command (TCT) Response (RMT) RESET A.3.4 SW Version Command (TCT) Response (RMT) RD_SW_VER INF_SW_VER A.3.5 Error messages Error Messages (RMT) ERR ERR_TX_IDRANGE ERR_IDRANGE ERR_SYNTAX

In case of full duplex communication it may happen that serial telegrams get corrupted and lost. Therefore it is recommended to check for “OK” where applicable. ERR Bit 7 Bit 0 Standard error message response if after a TCT command the operation could not be carried out successfully by the TCM. SET_BASEID Bit 7 Bit 0 With this command the user can rewrite its ID range base num-ber. The most significant ID byte is BaseIDByte3. The informa-tion of the 25 most significant bits is stored in FLASH. The allowed ID range is from 0xFF800000 to 0xFFFFFFFF. 32 0 BaseID This command can only be used a maximum number of 10 times. After successfully ID range reprogramming, the TCM answers with an OK telegram. If reprogramming was not successful, the TCM answers sending an ERR telegram if the maximum number of 10 times is exceeded or an ERR_IDRANGE telegram if the BaseID is not within the allowed range. 0xA5 0x5A 0x8B 0x58 X X X X X X X X X ChkSum 0xA5 0x5A 0x8B 0x19 X X X X X X X X X ChkSum 0xA5 0x5A 0xAB 0x18 BaseIDByte3 BaseIDByte2 BaseIDByte1 BaseIDByte0 X X X X X ChkSum 25 most significant bits 0 0 0 0 0 0 0

INF_BASEID Bit 7 Bit 0 This message informs the user about the ID range base number. BaseIDByte3 is the most significant byte. SET_RX_SENSITIVITY Bit 7 Bit 0 This command is used to set the TCM radio sensitivity. In LOW radio sensitivity, signals from remote transmitters are not detected by the TCM receiver. This feature is useful when only information from transmitters in the vicinity should be proc-essed. An OK confirmation telegram is generated after TCM sen-sitivity has been changed.
