1 GENERAL DESCRIPTION

1.1 Basic Functionality

The radio transmitter module PTM 330 from EnOcean

enables the implementation of wireless sensors and

switches without batteries.

Key applications are handheld remote controls or indus-

trial switches.

Functional Principle

When an energy pulse is supplied (e.g. by ECO 200 from

EnOcean) an RF telegram is transmitted including a

unique 32-bit module ID, the polarity of the energy

pulse, and the operating status of 4 digital inputs. The

RPS telegram content can be configured if other content is needed.

PTM 330 can be connected to ECO 200 via a contact spring. There are two meander struc-

tures on the PCB which allow usage of a rubber pad to set the level of two digital inputs.

Alternatively PTM 330 can be mounted as an SMD component onto a host PCB. In this case

energy supply pins and digital input pins are accessible via contact pads.

2.7.2 User defined operation

Via the configuration interface it is possible to define different content of DATA_BYTE3 and

define if a N-message or U-message shall be sent. This allows for example to transmit

other ORG=5 telegrams, e.g. “Mechanical handle”, as described in the EnOcean Equipment

Profiles defined by EnOcean Alliance.

2.8 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 0.7 ms. The delay between the three transmis-

sion bursts is affected at random.

3.5 Soldering information PTM 332/332C

PTM 332 has to be soldered according to IPC/JEDEC J-STD-020C standard.

PTM 332 shall be handled according to Moisture Sensitivity Level MSL4 which means a floor

time of 72 h. PTM 332 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..

PTM 332 modules have to be soldered within 6 months after delivery!

3.6 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

 Ferroconcrete 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 fiber

 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.

4 AGENCY CERTIFICATIONS (in preparation)

The modules have been tested to fulfil the approval requirements for CE (PTM 33x) and

FCC/IC (PTM 33xC) based on the built-in firmware.

4.1 CE approval

The modules bear the EC conformity marking CE and conforms 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 docu-

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 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).

4.2 FCC (United States) Certification

PTM330C and PTM332C LIMITED MODULAR APPROVAL

This is an RF module approved for Limited Modular use operating as an intentional trans-

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 PTM330C/PTM332C 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 EnOcean’s

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 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. 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 avail-

able 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.

OEM Requirements

In order to use EnOcean’s FCC ID number, the OEM must ensure that the following condi-

tions are met:

 End users of products, which contain the module, must not have the ability to alter the

firmware that governs the operation of the module. The agency grant is valid only when

the module is incorporated into a final product by OEM integrators.

 The end-user must not be provided with instructions to remove, adjust or install the

module.
