PRM15 1. General The PRM15 is a compact proximity reader with integrated antenna from the deister electronic HF product family. It has been designed for reading distances as used in door control applications.
PRM15 2. Technical Data Dimensions (mm): 300 x 300 x 30 mm Housing material: ABS Protection class: IP 54 (according to IEC 529) Electrical protection: Reverse polarity diode protection on power lines; high-speed transient voltage suppressor diodes on data lines Temperature range: +5 ...+60 °C (indoor use, non-condensing) -25 ...+60 °C (available for outdoor use) Power supply: 9...
PRM15 3. Mechanical Dimensions All dimension in mm.
PRM15 3.1 Rear view (opened housing) The switches S1, S2 and S3 will be explained in 7.1 “Easy Trim Function”.
PRM15 4. Wiring Diagram 4.1 2-Wire Wiegand 4.2 Magstripe Emulation/Data/Clock 4.
PRM15 5. Interfaces 5.1 Wiegand / Data/Clock max. 30 V max. 20 mA Pull-up resistor see above 5.2 Magstripe Emulation Pull-up resistor see above Pull-up resistor see above Pull-up resistor see above 5.3 Indicators 5 Function of LEDs and Beeper: Yellow LED: Reader is ready to operate. LED momentarily flashes during the reading of a card. Green LED, red LED, Beeper: The function of these indicators depends on how they are connected to the host system.
PRM15 5.4 RS485 Interface Most RS485 buses require termination resistors across the conductor pair. The need for termination has to be checked for each installation. Especially for high data rates, steep edges or long cables termination resistors are mandatory. Only both ends of the main cable, i.e. at the first and the last device, require termination resistors, additional resistors excessively load the drivers.
PRM15 6. Communications Protocol 6.1 Wiegand Standard 6.2 Data/Clock 6.
PRM15 6.4 Tamper Switch By connecting the terminal to further electrical devices it is possible for the user to control if the cover of the PRM15 housing is open or closed. The installation can be integrated into an alarm system in order to provide protection against tampering.

PRM15 The parity bits, the start and end characters, the LRC and the zero bits at the edge are generated automatically by the reader. On the one hand, they do not require space in the transponders (therefore we can encode 16 digits for the user), on the other hand this means that there will be a problem if one of the fields is missing.
PRM15 Calculation of the parity: LRC = 80h OR [52h Å 45h Å 30h Å 43h Å 35h Å 35h Å 37h Å 30h] = E3h (“Å” means Exlusive-OR) V10/09/08 rf_prm15_wi_en 15
PRM15 7. Installation 7.1 Easy Trim Function (ETF) This function allows adjustment of the reader to its environmental conditions. The ETF is a semiautomatic function for trimming the reader to its best performance. The ETF starts after switch S1 has been pressed (see 3.1 “Rear View”, switches). In this mode only one of the three LEDs is blinking. The individual meaning of each LED is as follows: Red LED: The rotatable switch (S2) must be turned to the right.
PRM15 7.3 Mounting considerations In order to ensure proper operation and an optimum reading/writing range take the following precautions: 1.) Mount all readers before tuning any of the readers. 2.) Ensure that the back-to-back distance is at least 50 cm. 3.) Ensure that the vertical separation distance is at least 50 cm. A narrower vertical separation gap may be used in case simultaneous reading/writing of a transponder by two readers is acceptable.
PRM15 8.
