1. GENERAL DESCRIPTION The radio transmitter device PTM 200C from EnOcean enables the implementation of wireless remote controls without batteries. Power is provided by a built-in electrodynamic power generator. The PTM 200C device serves the 315 MHz air interface protocol of EnOcean. Together with the receiver device RCM 130C, this device can be easily integrated in operation and control units for the implementation of different application specific system solutions.
1.2 Typical Applications • Building installation • Industrial automation • Consumer electronics Key applications are wall-mounted flat rocker switches with 1 or 2 rockers, as well as handheld remote controls with up to 4 single pushbuttons. Because the RF transmitters are self-powered (no batteries), maintenance-free RF systems are possible. 1.3 Features Overview Power supply: .............................................................

2.2 Contact Nipples Designation With 4 contact nipples, the PTM 200C offers 2 channels with 4 action states each (upper/lower nipple is pressed/released when activating the energy bow). The nipples’ designation is as follows: STATE O A CHANNEL B I Figure 10: Contact nipple designation Radio signals of the PTM 200C device are event-controlled (energy bow is pressed/released) with contact nipple code (channel/state) and unique device identification (fixed 32-bit ID).
2.3 PTM 200C Radio Telegram For the transmission of the telemetric signals, EnOcean has defined a new dynamic radio data telegram that is adapted to the individual application.
2.3.4 Reliable radio transmission within systems operating many sensors The very short telegrams of EnOcean transmitters enable the operating of a large number of transmitters within the same radio cell; the error rate caused by telegram collisions remains extremely low. Statistically viewed, the transmission reliability is still greater than 99.99% in the case of 100 radio sensors that transmit once every minute.
3. APPLICATIONS INFORMATION 3.1 Laying the antenna > 25mm For best performance the antenna cable should be layed as shown in the figure below. ~ 63mm A B I ~ 102mm O ~ 42mm Figure 13: Laying the antenna Important note: o The distance between antenna foot point and antenna end must be > 25mm o The antenna area should be maximized o The antenna should be placed at the same height above the ground plane as the rotation axis for the switch rocker (see example below) ©EnOcean GmbH, W.
Figure 13: Example of a well suited antenna 3.2 Construction of application specific Switch Rockers For CAD system development support, 3D construction data is available from EnOcean (IGS data). Using this data, the mechanical interface is fixed, and the shape and surface of the rocker(s) can be changed according to requirements. Recommendation for suitable rocker material is Ultradur B 4520 with a surface roughness of min. Ra 1.0 ym.

3.5 FCC/IC Approval Requirements This device complies with Part 15 of the FCC Rules and with RSS-210 of Industry Canada. If this device is operated in compliance with the following requirements it can be operated without notification and free of charge in the area of the United States of America and in Canada.
4. DEVELOPMENT TOOLS 4.1 Evaluation Kit EVA 105C EVA 100C is an evaluation kit to support a simple setting-up operation of the receiver side when the EnOcean transmitter device PTM 200C is evaluated. EVA 100C supports a quick evaluation of RCM 130C receiver operation modes and supports the fast development of applications.
5. Patent protection PTM200C is protected by the following patents: o o o US 6,747,573 US 7,019,241 Further patents pending ©EnOcean GmbH, W. Heller Page 19 of 19 PTM 200C User Manual V1.
