PTM 230

1 GENERAL DESCRIPTION

The radio transmitter module PTM 230 from EnOcean enables the
implementation of batteryless radio switches for applications in
e.g. building technology or industrial automation. Power is
provided by an external electro-dynamic power generator such as
ECO 100 or a short energy pulse.

The PTM 230 module serves the 868 MHz air interface protocol of
EnOcean. Together with the receiver module RCM 120, this
module can be easily integrated in operation and control units for
the implementation of different application-specific system
solutions.

1.1 Functional Principle

When a short energy pulse is supplied to the PTM 230 module an RF telegram is transmit­ted including a 32-bit module ID and the polarity of the supply voltage. In addition the in­formation of 2 inputs is transmitted. With the 2 inputs one rocker of a PTM 200 can be
simulated.

1.2 Features Overview

Power supply external electro-dynamic power generator or energy pulse
Frequency / Transmission power 868.3 MHz / max. 10 mW EIRP
Data rate / Channel bandwidth / Modulation type 120 kbps / 280 kHz / ASK
Minimal switching interval 45 ms
Antenna λ/4-whip antenna mountable, no antenna mounted
Transmission range approx. 300 m free field, 10m in industrial environment

range strongly dependent on surrounding material and position relative to energy harvester or metal surfaces

Serial Telegram type (RCM120) RPS of type 2
Module identifier individual 32-bit ID (factory programmed)
Radio standards R&TTE 1999/5/EC, ETSI EN 300220-3 V1.1.1
EMC standards 89/336/EC, 92/31/EWG, EN 61000-6-2, EN 61000-6-4

2.3 PTM 230 Radio Telegram

2.3.1 Frequency range and transmission cycle allowed

The EnOcean technology operates the 868.3 MHz radio channel, which is exclusively re­leased for short-time data transmission in Europe. All transmitters have to stick to a duty
cycle of max. 1% within one hour. Permanent transmitters such as radio earphones are not
allowed. For conventional applications, it must be ensured that the PTM 230 radio module is
not operated more than 15000 times within one hour (one operation: button is pressed and
released). Within this calculation, the extraordinary short telegram length is considered
including three subtelegrams.

2.3.2 Modulation process

As modulation process, EnOcean uses incoherent amplitude modulation (ASK). Digital am­plitude modulation enables the implementation of very efficient energy-saving transmitters
because only the “1”-bits are transferred. At the same interference signal level, the trans­mission security of the alternative FSK method is identical to that of the ASK method.

(Reference: Pehl, Digitale und analoge Nachrichtenübertragung, Hüthig 2001)

2.3.3 Transmission timing

The transmission timing of the radio module PTM 230 has been developed to avoid possible
collisions with data packages of other EnOcean transmitters as well as disturbances from
the environment.

With each transmission cycle, three identical subtelegrams are transmitted. The transmis­sion of a subtelegram lasts approximately 0.7 ms. To optimize data security, each telegram
is repeated twice within about 20 ms, whereas the delay between the second and the third
transmission burst is effected at random.

3 APPLICATION INFORMATION

3.1 Antenna Mounting

Positioning and choice of receiver and transmitter antennas are the most important factors
in determining system transmission range. The PTM 230 modules are supplied without an­tenna. For standard applications the use of a whip antenna is recommended (87 mm/ 0.14
mm

2

Cu-wire). This antenna enables very compact unit with good radio characteristics. For
mounting the antenna, the following notes should be considered to optimize the system
performance:

Mounting a 1/4-wave whip antenna:

For good transmit performance, great care must be taken about the space immediately
around the antenna since this has a strong influence on screening and detuning the an­tenna. The antenna should be drawn out as far as possible and must never be cut off. Pri­marily, the far end of the wire should be mounted as far away as possible from all metal
parts, PCB strip lines and fast logic components (e.g. microprocessors). To avoid radio fre­quency hash from the motherboard, which desensitizes the unit, PCB strip lines on the
motherboard should be designed as short as possible, and using PCB ground plane layer is
also recommended. To avoid possible damage to the module the end of the antenna should
be insulated.

Note that 868 MHz whip antennas do not show any directional effects under free-field ra­dio-wave propagation conditions (spot-wise radiator).

3.2 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 these system conditions, range tests should categorically be per­formed before notification of a particular range that will be attainable by a particular appli­cation.

The following figures for expected transmission range are considered by using the PTM 100
radio transmitter module and the RCM 110 or RCM 120 radio receiver module with the pre­installed whip antennas and may be used as a rough guide only:

• 10 m in industrial applications with metal in the vicinity

• 30 m for obstructed environment (e.g., through two brick walls inside a building)

• 300 m for unobstructed environment (“free field”)

Further notes to determine the transmission range within buildings are available as down­load from www.enocean.com

.

3.3 Approval Requirements

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 corresponding do­cumentation has been deposited at EnOcean. The modules can be operated without notifi­cation and free of charge in the area of the European Union, in Switzerland, in Cyprus, in
Czech, in Estonia, in Hungary, in Latvia, in Lithuania, in Malta, in Poland, in Romania and in
Slovenia. 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 transmitters are used according to the regulations of the 868.3 MHz band, a

so-called “Duty Cycle” of 1% per hour for each transmitter must not be ex­ceeded (also see chapter 2.3.1).
