deister electronic GmbH 30890 Barsinghausen Germany 7V19/07/04RDL150 RS485/RS2324. RS485 InterfaceMost RS485-buses require termination resistors across the conductor pair. The need for termina-tion has to be proofed for each installation. Especially for fast transitions, high data rates or longcables the resistors are absolutely necessary. Only both ends of the main cable require terminationresistors, additional resistors excessively loads the driver. The resistor value matches the cable'sdifferential-mode characteristic impedance (100-120 Ohm).At the RS485-bus you need a controller with fail-safe biasing, meaning a pull-up and a pull-downresistor on the cable. The fail-safe biasing provides a known state in which there is no activedriver on the bus and therefore it is essential, independent from data rates and length of the cable.(Bus with RS485 interface)Technical data (for baud rates up to 100 kHz):Max. cable length: 1200m (4000 feet)Max. stub length: because of reflections stubs should be as short as possibleExceptions allow a length up to 5 m (16 feet)Recommendationfor the cable: twisted pair, cable-cross-section at least 0,22mm² (AWG 24)differential-mode characteristic impedance 100-120 Ohm
deister electronic GmbH 30890 Barsinghausen Germany 8RDL150 RS485/RS232V19/07/045 Mechanical DimensionsAll dimensions in mmStatus: red LED, displays errors and error telegrams or valid dataRead: green LED, displays succesful reading of a transponderPower: yellow LED, always lighting if power supply is connectedFurther explanation on page 10.
deister electronic GmbH 30890 Barsinghausen Germany 9V19/07/04RDL150 RS485/RS2325.1 Rear view (opened Housing)The switches S1, S5 and S7 will be explained in chapter 4.3
deister electronic GmbH 30890 Barsinghausen Germany 10RDL150 RS485/RS232V19/07/045.2 LED Explanation1) Yellow LED: Line voltage indicatorAfter connecting the power supply, the device shows it is ready to operate by permanentlyactivating the yellow LED. If a transponder is read, the yellow LED turns off for a moment. 2) Green LED: Read indicatorIf a transponder data was read, the answer telegram is sent and the reader activatesthe green LED for about 50 ms. No visual activity of LED during write instructions.3) Red LED: Status indicatorDisplays error telegrams.The LED activates for about 200ms on the following events:• Communication error telegrams• Non executable commands• If the reader is set to polling mode (see Rdemo description, chapter xx) and a transponderis identified, the red LED lights up while the “valid data” is not polled by the host system.4) General status indicator:The green LED and the red LED are activated while the yellow LED is deactivated.This occurs during:• The start up phase after switch on the reader• While updating the firmwareThe description for upgrading the firmware will be found in chapter 6• Undervoltage operation of the reader (e.g. U < 8 V/DC)
deister electronic GmbH 30890 Barsinghausen Germany 11V19/07/04RDL150 RS485/RS2325.3 Easy Trim Function (ETF)This function allows adjusting the reader to its environmental conditions.The ETF is a semiautomatic function for trimming the reader to its best performance.The ETF starts if switch S1 is pressed.In this mode only one of the three LEDs is blinking. The individual meaning of each LED is:Red LED: The rotatable switch (S5) must be turned to the rightYellow LED: The rotatable switch (S5) must be turned to the leftGreen LED: The setting of the rotatable switch (S5) matched the best performance.It could be possible that there are two settings of the switch that match the best performance.If there are two possible positions of the rotatable switch (S5), it is better to choose the positionbefore the yellow LED is blinking.The ETF ends after switch S1 is pressed again. It also ends after 6 minutes.If the reader should be mounted directly on metal ground (distance to metal is lower than2 cm) the switch S7 must be actuated before the rotatable switch is turned.
deister electronic GmbH 30890 Barsinghausen Germany 12RDL150 RS485/RS232V19/07/046 Installation Instructions6.1 Possible Interference Sources*Warning:It is possible that external interference sources will influence the read range, e.g. monitors,switching power supplies, power cables parallel to data cables, mounting on metal etc.)Note:With growing distance between reader and interference source the influence decreases.LCD monitors have a minimal influence on the read range. In particular the reader should bemounted on non-metallic material, such as plastic or wood. Metal screws (M6 - ISO 1207, 4762or 7045) for mounting the reader have an insignificant influence on the read range.Use only regulated power supplies. deister electronic GmbH offers suitable power supplies.To reduce the influence of external electrical interference, connect the cable shield to ground(GND) of the power supply.
deister electronic GmbH 30890 Barsinghausen Germany 13V19/07/04RDL150 RS485/RS2326.2 Mounting ConsiderationsThe following problems may occur when mounting multiple RDL150 readers in close proximity.• The signal energy from one reader may interference with the read/write range of the other.• Overlapping read/write fields can cause a single transponder to be read/write simultaneouslyby two or more readers.To ensure proper operation and optimal read/write range, take the following precautions:Figure: Visualization of separation distances (vertical and back-to-back)1. Mount all readers before tuning any of the readers2. Ensure that the back-to-back distance is at least one meter• Note 1: If a metal plate is installed between the two readers, the back to back distance may be ignored. However, read/write range will be reduced to approx. 240 mm.• Note 2: Reduced transponder read/write range and the simultaneous read/write of a trans-ponder by both readers may result if the readers are installed less than 500 mm.3. Ensure that the vertical separation distance is at least 500 mm. A more narrow vertical separation gap may be used if the simultaneous read/write of a transponder by tworeaders is acceptable.min. 500 mmmin. 500 mm
deister electronic GmbH 30890 Barsinghausen Germany 14RDL150 RS485/RS232V19/07/047 Upgrading FirmwareTo perform a firmware update with deFlash please follow the steps below:• Connect reader serial interface with PC, then plug in power supply.• Start deFlash.exe• Select the COM-Port the reader is connected with.• Click 'Load File' and open the update file (xxxxx.bin) related to the device.
deister electronic GmbH 30890 Barsinghausen Germany 15V19/07/04RDL150 RS485/RS232• Start programming procedure by clicking 'Program'.• Program displays "Flash Loader Programming" while the green LED and the red LED areswitched on and the yellow LED is deactivated.• Wait until display shows, "Programming finished Version XXXXXX". • 'Exit' program.• If programming fails, repeat procedure as described above.• If repetition fails again, please disconnect power supply of reader, restart program deFlash.exe and plug in power supply of reader within 5 seconds. Programming processshould run properly now.• If this update variation also fails, please contact your service partner or sales representativeat deister electronic GmbH.
