5. Interfaces 5.1 Wiegand / Data/Clock 5.2 Magstripe Emulation 5.3 IndicatorsNote:For all interfaces except RS485 the pull-ups have to be connected to the clock and to the data lines as well. The value of the pull-ups depends on the current and voltage which is required for the controller input.V10/09/08 rf_prm15_wi_en 9PRM15Function of LEDs and Beeper:Yellow LED:Reader is ready to operate.

5.4 RS485 InterfaceMost 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. The resistor value matches the cable´s differential mode characteristic impedance (in most cases 100 − 120 Ω).At the RS485 bus you need a controller with fail-safe biasing meaning a pull-up and a pull-down resistor on the cable. The fail-safe biasing provides a known state in which there is no active driver on the bus. Therefore this is essential regardless of data rates and length of cables.Technical data (for baud rates up to 100 kBps):Max. cable length: 1200 m (4000 feet)Max. stub length: because of reflections stubs should be kept as short as possible;exceptions allow a length up to 5 m (16 feet)Recommendation for the cable: twisted pair, cable-cross section at least 0.22 mm2 (AWG 24) differential-mode characteristic impedance 100 − 120 Ω10 rf_prm15_wi_en V10/09/08PRM15

6.4 Tamper SwitchBy 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.12 rf_prm15_wi_en V10/09/08PRM15
6.5 Magstripe Interface according to ISO 7811/2-1995Data Encoding TableValue Bitpattern Meaning0 0 0 0 0-1 “0”1 1 0 0 0-0 “1”2 0 1 0 0-0 “2”3 1 1 0 0-1 “3”4 0 0 1 0-0 “4”5 1 0 1 0-1 “5”6 0 1 1 0-1 “6”7 1 1 1 0-0 “7”8 0 0 0 1-0 “8”9 1 0 0 1-1 “9”10 (Ahex) 0 1 0 1-1 unused character11 (Bhex) 1 1 0 1-0 start sentinel (start character)12 (Chex) 0 0 1 1-1 unused character13 (Dhex) 1 0 1 1-0 field separator14 (Ehex) 0 1 1 1-0 unused character15 (Fhex) 1 1 1 1-1 end sentinel (stop character)The least significant bit of every digit is sent first; the fifth bit is an odd parity bit for each group of 4 data bits.The complete message always looks as follows:left edge - start - data characters - end - LRC - right edgeThe LRC is calculated by the following procedure:Each of the 4 bits in the LRC character is an even parity bit of the equivalent bits in the telegram including start and stop sentinel; i. e. the first LRC bit is an even parity bit for all the least significant bits in the telegram and the 4th bit of the LRC is the even parity of all the most significant bits.The fifth bit is the odd parity of the 4 LRC bits (it is not calculated over all the parity bits).On magstripe cards the space left and right of the information (edge) is filled with an unknown number of zero bits (this is not a valid character as the parity is invalid). As most terminals need some of the zero bits (known as “clocking bits” too) and do not care about additional zero bits, deister decided to send 16 zero bits at the left edge as well as to the right edge.V10/09/08 rf_prm15_wi_en 13PRM15
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.Example:The short information “86” would be transmitted as follows:0000000000000000-11010-00010-01101-11111-01011-0000000000000000edge start “8” “6” stop LRC edgeA “1”-bit is transmitted as a logic low level; the falling as well as the rising edge of the clock pulse may be used to clock in data. 6.6 Protocol for PRM15 with RS485 (no partyline protocol)The interface is operated using 9600 baud, 8 data bits, 2 stop bits and no parity bit.Message Format: Example14 rf_prm15_wi_en V10/09/08PRM15
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 15PRM15
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.Yellow LED: The rotatable switch (S2) must be turned to the left.Green LED: The setting of the rotatable switch (S2) matched the best performance.In some cases there might be two settings of the switch indicating the best performance. If there are two possible positions for the rotatable switch (S2), we recommend to select the position before the yellow LED has been blinking.The ETF ends after switch S1 has been pressed again. It will also end automatically after 6 minutes.If the reader should be mounted directly on metal surfaces (distance to metal less than 2 cm), switch S3 has to be actuated before the rotatable switch S2 is being turned. 7.2 Possible Interference SourcesWarning:It is possible that external interference sources may influence the reading range, e.g. monitors, switching power supplies, power cables parallel to data cables, mounting on metal surfaces etc.LCD monitors have a minimal influence on the reading range. In particular the reader should only be mounted on non-metallic material, such as plastic or wood. Metal screws (M6 – ISO 1207, 4762 or 7045) for mounting of the reader have an insignificant influence on the reading range.The unit needs to be operated with a power source with limited power consumption according to EN 60950-1(2001) paragraph 2.5.Note:With growing distance between reader and interference source the influence will decrease.Use only linearly regulated power supplies which are offered by deister electronic GmbH. In order to reduce the influence of external electrical interference the cable shield has to be connected to ground (GND) of the power supply.16 rf_prm15_wi_en V10/09/08PRM15
7.3 Mounting considerationsIn 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.Note:●If a metal plate has been installed between the two readers, the back-to-back distance may be ignored. However, the reading/writing range will be reduced by approximately one third.●Reduced transponder reading/writing range and the simultaneous reading/writing of a transponder by two or more readers may result if the readers are being installed less than 50 cm apart.Picture: Visualization of separation distances (vertical and back-to-back)V10/09/08 rf_prm15_wi_en 17PRM15
