USER MANUAL TCM 300 / TCM 300C / TCM 300U TCM 320 / TCM 320C / TCM 320U 4 APPLICATIONS INFORMATION 4.1 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 TCM 300 / TCM 300C / TCM 300U TCM 320 / TCM 320C / TCM 320U 4.2 Antenna options TCM 300x 4.2.1 Overview Several antenna types have been investigated by EnOcean. Please refer to our application notes AN102, and AN105 which give an overview on our recommendations. All TCM3x0 modules have been approved with whip antenna, and TCM300U with helical antenna in addition. 868.

USER MANUAL TCM 300 / TCM 300C / TCM 300U TCM 320 / TCM 320C / TCM 320U 4.3 Antenna options TCM 320x TCM320x is equipped and approved with a whip antenna. Specification of the TCM whip antenna: L=150 mm @ 315 MHz, L=86 mm @ 868.3 MHz, L=64 mm @ 902.875 MHz AWG24 wire composed of 7 strands of AWG32 wire Material is PVC according to DIN VDE 0207 Self-extinguishing and flame retardant according to EN 50265-2-1 / IEC 60332-1 Isolation material may break at temperatures below -15 °C.
USER MANUAL TCM 300 / TCM 300C / TCM 300U TCM 320 / TCM 320C / TCM 320U 4.3.1 Positioning of the whip antenna Positioning and choice of receiver and transmitter antennas are the most important factors in determining system transmission range. For good receiver 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.
USER MANUAL TCM 300 / TCM 300C / TCM 300U TCM 320 / TCM 320C / TCM 320U For 315 MHz and 902 MHz modules (TCM 320C and TCM 320U) please note that a full radio approval needs to be performed if modules are used with external antennas other than the pre-installed whip antenna. When using the SMA connector pads please make sure no mechanical forces are exerted on the 16-pin connector! It is recommended to use a strain relief for that purpose. © 2013 EnOcean | www.enocean.

USER MANUAL TCM 300 / TCM 300C / TCM 300U TCM 320 / TCM 320C / TCM 320U 4.5 Power supply requirements In order to provide a good radio performance, great attention must be paid to the power supply and a correct layout and shielding. It is recommended to place a 22 µF ceramic capacitor between VDD and GND close to the module (material: X5R, X7R, min 6.3 V to avoid derating effects). In addition a 470 nH coil shall be inserted (Murata LQW18A, 0603) in the power supply line.
