USER MANUAL

TCM 515 –ENOCEAN TRANSCEIVER GATEWAY MODULE

1General description

1.1 Basic functionality

TCM515 is an addition to the existing TCM 300 / 310 / 320 transceiver module family con-

sisting of the following products:

◼TCM 515

868.3 MHz ASK, EnOcean Radio Protocol version 1, main market Europe

◼TCM 515U

902.875 MHz FSK, EnOcean Radio Protocol version 2, main market US and Canda

The term “TCM 515” in this document refers to all members of the TCM 515 family unless

noted differently.

TCM 515 products are limited to OEM installation ONLY.

TCM 515 is optimized for application requiring smallest possible size and integrated security

handling such as line-powered actuators or controllers.

For applications requiring highest radio performance - such as gateways or access points

covering larger areas –consider using TCM 310 which provides the highest possible sensitiv-

ity and noise immunity.

TCM 515 provides a transparent radio link between EnOcean radio devices and an external

host connected via UART interface using the standardized EnOcean Serial Protocol V3 (ESP3)

communication protocol.

TCM 515 receives and transmits radio telegrams based on a 50 Ohm or whip antenna con-

nected to the host PCB. It forwards received radio telegrams to an external host processor

or host PC via the ESP3 interface. Messages received from an external host via the ESP3

interface will be transmitted by TCM 515 as EnOcean radio telegrams according to the chosen

frequency.

TCM 515 is implemented as 31 pin reflow-solderable module with optimized form factor for

size constrained applications. It is not pin compatible with existing TCM 310 products. Figure

1 below shows TCM 515.

Note 2: TCM 515 up to revision DB-08 requires approximately 50 ms in total for start-up after power up. Starting

from revision DB-09, this time is reduced to approximately 15 ms in total.

During start-up, TCM 515 waits for a configurable additional delay period before starting RX mode to allow for power

supply stabilization. The default delay period is 200 ms; this is adjustable via ESP3 command (see chapter 3.2)

Note 3: TX to RX switch over time is measured from the transmission of the last bit (end of frame) of a radio frame

until the receiver is ready to receive the first bit (preamble) of a radio frame

2Functional information

2.1 High level functionality

TCM 515 is a fully integrated radio transceiver family which enables communication with

other devices implementing the EnOcean Radio Protocol (ERP).

TCM 515 is used to exchange (send and / or receive) radio telegrams with external sensors,

switches or actuators.

TCM 515 is connected to an external host which for instance could be a microprocessor, a

controller or a gateway via the EnOcean Serial Protocol v3 (ESP3) interface.

ESP3 commands are listed within this document for information purposes only; for details

about ESP3 commands refer to the ESP3 specification available from

https://www.enocean.com/esp3

Figure 2 below shows the integration of TCM 515 into a typical system environment.

Figure 2 –TCM 515 system environment

USER MANUAL

TCM 515 –ENOCEAN TRANSCEIVER GATEWAY MODULE

2.2 Functional modes

TCM 515 implements the following functional modes:

◼Power-up and system initialization

◼Telegram reception (including security processing, filtering and repeating if required)

◼Telegram transmission (including security processing if required)

◼Low Power Sleep

The transition between these functional modes is shown in Figure 3 below

Figure 3 –TCM 515 functional modes

Subsequent chapters describe these functional modes in more detail.

USER MANUAL

TCM 515 –ENOCEAN TRANSCEIVER GATEWAY MODULE

2.3 Device Interface

TCM 515 implements a 31 pin reflow-solderable interface. Solder mask data is available on

request from EnOcean.

2.3.1 Pin-out

The pin assignment (as seen from the top of the device) is shown in Figure 4 below. Solder

mask and mechanical data is available from EnOcean.

USER MANUAL

TCM 515 –ENOCEAN TRANSCEIVER GATEWAY MODULE

2.4 Power supply

TCM 515 is supplied by the VDD and GND Pins and supports a supply voltage range from 2.0

V to 3.6 V. For best radio performance it is very important to minimize noise on the supply

voltage lines. Please see chapter 11.5 and 11.6.

2.5 Antenna

TCM 515 receives and transmits data based on a 50Ω whip antenna connected to its RF_50

input (Pin 2). Please see chapter 12.

2.6 UART interface

TCM 515 communicates with the external host using the standard ESP3 serial (UART) inter-

face based on the signals UART_TX (Pin 21, direction from TCM 515 to external host) and

UART_RX (Pin 20, direction from external host to TCM 515).

The default interface speed of the ESP3 interface is 57600 bit per second and data is trans-

mitted using 8 data bits, 1 STOP bit and no parity (8N1).

It is possible to select faster communication speeds during operation using the ESP3

CO_SET_BAUDRATE command (see chapter 9.1). The following interface speeds are sup-

ported by TCM 515:

◼57600 bit per second

◼460800 bit per second

Additionally, it is possible to change the default ESP3 interface speed at power up from

57.600 Bit per second to 460.800 Bit per second by connecting the nTURBO input (Pin 31,

active low) to Ground.

Subsequent modification of the interface speed during operation using the CO_SET_BAU-

DRATE command is always possible irrespective of the state of the TURBO input pin. Care

should be taken not to select a UART interface speed which cannot be supported by the

connected host processor as this would prevent subsequent communication.

USER MANUAL

TCM 515 –ENOCEAN TRANSCEIVER GATEWAY MODULE

2.7 Reset

TCM 515 can be reset by pulling the nRST pin (Pin 24, active low) to Ground. Please see

chapter 11.9 for reset circuit recommendations.

2.8 Test Interface (TP1, TP2, TP3)

TCM 515 provides a test interface (TP1, TP2 and TP3). The intended use of this interface is

for analysis and debugging of customer products by EnOcean. It is strongly recommended

that customer PCB design provides the ability to connect to this interface.

USER MANUAL

TCM 515 –ENOCEAN TRANSCEIVER GATEWAY MODULE

3Power-up and system initialization

After power-up, TCM 515 executes the following functions:

◼Initialization of the MCU

◼Wait for pre-configured delay (default 200 ms)

◼Initialization of the radio

After that, TCM 515 is in ready for operation and will transition to receive mode.

3.1 Start-up timing

For TCM 515 devices up to device revision DB-08, the typical start-up time is 50 ms (exclud-

ing the configured additional delay).

For TCM 515 devices starting with device revision DB-09, start-up time and power consump-

tion has been reduced resulting in a shortened start-up sequence shown in Figure 5 below.

3.2 User-configurable delay

TCM 515 provides the option for a configurable additional delay between start-up and oper-

ation to allow the external power supply to stabilize before the device starts the radio. The

factory-programmed default value of this delay is 200 ms. It can be configured as persistent

parameter (maintained after power down) using the ESP3 command CO_WR_STARTUP_DE-

LAY.

USER MANUAL

TCM 515 –ENOCEAN TRANSCEIVER GATEWAY MODULE

4Telegram reception

After start-up, TCM 515 will enter receive mode. For each received telegram, TCM 515 per-

forms the following functions:

◼RX Frame processing

Received data bitstream is processed (detection and removal of preamble, start of

frame, end of frame and redundant bits, CRC check, subtelegram merge) and format-

ted as EnOcean radio telegrams

◼Repeater handling

Received telegrams are checked if they should be repeated based on the repeater

mode configured at TCM 515 (L1 Repeater, L2 Repeater, Selective Repeater) and the

repeater information reported as part of the radio telegram. If the received telegram

should be repeated then it will be inserted into the transmission queue. See chapter

6 for details on the repeater functionality.

◼Telegram filtering

Received telegrams can be classified according to user-defined characteristics so that

only telegrams matching these characteristics will be processed and forwarded to the

external host via the ESP3 interface. See chapter 4.2 for details.

◼Security processing

Telegrams from senders using high security mode can be automatically decrypted and

authenticated according to their security parameters stored in the inbound secure link

table. See chapter 7 for details.

◼ESP3 formatting and telegram forwarding

Processed telegrams will be formatted as ESP3 message and forwarded to the external

host via the ESP3 interface. See chapter 9 for details.

USER MANUAL

TCM 515 –ENOCEAN TRANSCEIVER GATEWAY MODULE

4.1 RX maturity time

The reception (RX) maturity time defines the longest possible interval between the reception

of the first subtelegram and the reception of the last subtelegram belonging to the same

telegram.

Considering the worst case of a telegram received after two levels of repeating, the RX ma-

turity time is always < 100 ms (39 ms + 29 ms + 29 ms) as shown in Table 9.

TCM 515 can be configured to wait for the RX maturity time (100 ms) after reception of a

subtelegram in order to determine the number of received subtelegrams. TCM 515 will in

that case report the actual number of received subtelegrams to the external host.

Alternatively, TCM 515 can be configured to immediately forward a received subtelegram to

the host and discard subsequent identical subtelegrams. This provides the lowest latency and

is the default operation mode for TCM 515.

The selection between these two options is done using the CO_WR_WAIT_MATURITY com-

mand as shown in Table 2 below.

4.2 Telegram filtering

By default, TCM 515 will forward all valid telegrams received by it (including such that are

addressed to a different receiver) to the host via its ESP3 interface.

Filtering allows to setup TCM 515 to forward only specific telegrams (e.g. only such that are

addressed to it) to the external host. Only radio telegrams that match specific user-defined

parameters will be forwarded to the external host (selective forwarding) or repeated (selec-

tive repeating).

Filtering therefore can be used to limit the amount of telegram processing required at the

external host or to optimize the available radio bandwidth.

4.2.1 Filter types

Telegram filtering is the process by which only radio telegrams that match specific user-

defined parameters will be forwarded to the external host (selective forwarding) or repeated

(selective repeating). The following parameters can be used as filter condition:

◼Source ID

Only radio telegrams originating from a specific sender (identified by its EnOcean Uni-

versal Radio ID = EURID) will be processed.

This filter type can be used for instance in actuators which only accept input from

devices (e.g. switches) that have been learned in.

◼Destination ID

Only radio telegrams addressed to a specific receiver (as identified by its EURID) will

be processed. This filter type can be used by a receiver to accept only radio telegrams

intended for itself.

Note that the Broadcast ID (0xFFFF:FFFF) cannot be used as destination ID filter.

◼Telegram Type (RORG)

Only radio telegrams of a specific type (RPS, 1BS, 4BS or VLD) will be processed. This

filter type can be used for instance if an actuator should react only on switch (RPS)

telegrams.

◼Received signal strength (RSSI)

Only radio telegrams above or below a specific signal strength will be processed.

The first case –above - can for instance be used during learn-in if an actuator should

only accept teach-in telegrams from devices close to the receiver.

The second case –below - can be used in repeaters where only weak signals (with

low RSSI) should be repeated in order to limit radio congestion.

Table 3 –CO_WR_FILTER_ADD

Each filter criterion can be defined as positive filter (message is forwarded / repeated if the

condition is true) or as negative filter (message is forwarded / repeated if the condition is

false). If for instance the filter condition is a certain source ID then it can be selected if only

telegrams originating from this source ID are repeated / forwarded (positive filter) or if all

messages except the one originating from this source ID are repeated / forwarded (negative

filter).

Moreover, for each filter criterion it can be defined if it shall apply for the forwarding func-

tionality or for the repeating functionality of TCM 515. The maximum number of filter criteria

is 30. Attempting to define more filter criteria will result in the response 01: RET_ERROR

(memory space full).

Note that more than one filter can be defined, e.g. it is possible to setup filter rules such that

telegrams originating from several source ID will be processed. If more than one filter con-

dition per functionality is defined then it can be defined if all conditions must be true (logical

AND) or one of the conditions must be true (logical OR).

4.2.3 Filter enabling

Once all filters have been defined, the CO_WR_FILTER_ENABLE command shown in Table 4

below has to be used to select the logical relation between the defined filters (logical AND

versus logical OR) and to enable the filtering mechanism for telegram forwarding via ESP3.

Table 4 –Syntax for CO_WR_FILTER_ENABLE command

The use of filters for the repeater is enabled by means of the CO_WR_REPEATER command

shown in Table 5 below. There, REP_ENABLE has to be set to 0x02 to enable selective re-

peating based on the defined filters.
