USER MANUAL V0.904 STM110C 2.8 Serial Data Reception via Transceiver Modules TCM 200C / TCM 210C For a detailed description please refer to the User Manual of TCM200C/TCM210C. Type of STM110C protocol which is seen at the serial outputs of the receiver modules is “4BS” (4 Byte Sensor): Description of STM110C radio data content: ORG = 7 dec.
USER MANUAL V0.904 STM110C 3 APPLICATIONS INFORMATION 3.1 Module Mounting User PCB User PCB Space required Energy stores The STM110C module requires some external circuitry configuration and connecting to the application-specific sensorics circuit. This external circuitry should easily find place on a small PCB that can be connected upside down to the EnOcean module via the STM dual row header. This allows the realization of very compact sensor units.
USER MANUAL V0.904 STM110C 3.2 Antenna Mounting Positioning and choice of receiver and transmitter antennas are the most important factor in determining system transmission range. The STM110C transmitter module is supplied with a soldered whip antenna as standard. By using that antenna, very compact sensor equipment can be implemented with good radio transmission characteristics.
USER MANUAL V0.904 STM110C 3.3 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.
USER MANUAL V0.904 STM110C 3.4 Connecting the solar cell The supplied solar cell has been designed especially for maximum module performance at smallest dimensions. The active solar area is divided into two to provide independent module power supplies: V_SC1: Main power supply input. Must be connected to the small active area of the solar cell or to another external energy source respectively V_SC2: Goldcap charging input.
USER MANUAL V0.904 STM110C 3.5 Solar Cell Handling, Soldering & Mounting The EnOcean solar cell technology guarantees the highest stabilized efficiency values. At the front, the solar modules have a glass covering that protects the photovoltaic layer from the effects of the environment and weather. The rear features contacts for the electrical connection. Handling Prevent injuries due to the sharp glass edges.
USER MANUAL V0.904 STM110C (a) In Pb alloy soldering, the soldering iron shall be set up and stabilized at 240°C before and in the calibration. For Pb-free solder wire, the soldering iron shall be set up and stabilized at 255°C before and in the calibration. (b) Take little solder wire on the soldering iron tip and put the tip in contact with the contact-pad of the temperature meter for 1 minute.

USER MANUAL V0.904 STM110C Corrosion protection Corrosion protection is essential to the lifetime of the solar module. The solar module is extremely resistant to temperature effects. But mounting must particularly provide protection against humidity. The proper choice of suitable sealing material is important. The best method is protection by a transparent cover, mainly important for outdoor applications. Also well-suited is a casing by silicone (not acrylic!).
USER MANUAL V0.904 STM110C 3.6 Using an Alternative Power Supply, e.g. Battery Alternatively to the use of the supplied solar cell, the module power supply input V_SC1 can be driven by another suitable external energy source. The external energy source must fulfill the following requirements: Parameter Open circuit voltage Ampacity (Peak) Ampacity (continuous) Min 2.2 10 1 Typ Max 5.
