RS485 Interface Most RS485-buses require termination resistors across the conductor pair. The need for termination has to be proofed for each installation. Especially for fast transitions, high data rates or long cables the resistors are absolutely necessary. Only both ends of the main cable require termination resistors, additional resistors excessively loads the driver. The resistor value matches the cable's differential-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-down resistor on the cable. The fail-safe biasing provides a known state in which there is no active driver 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 possible Exceptions allow a length up to 5 m (16 feet) Recommendation for the cable: V19/07/04 twisted pair, cable-cross-section at least 0,22mm² (AWG 24) differential-mode characteristic impedance 100-120 Ohm deister electronic GmbH 30890 Barsinghausen Germany RDL150 RS485/RS232 Mechanical Dimensions All dimensions in mm Status: red LED, displays errors and error telegrams or valid data Read: green LED, displays succesful reading of a transponder Power: yellow LED, always lighting if power supply is connected Further explanation on page 10. deister electronic GmbH 30890 Barsinghausen Germany V19/07/04 RDL150 RS485/RS232 5.1 Rear view (opened Housing) The switches S1, S5 and S7 will be explained in chapter 4.3 V19/07/04 deister electronic GmbH 30890 Barsinghausen Germany RDL150 RS485/RS232 5.2 LED Explanation 1) Yellow LED: Line voltage indicator After connecting the power supply, the device shows it is ready to operate by permanently activating the yellow LED. If a transponder is read, the yellow LED turns off for a moment. 2) Green LED: Read indicator If a transponder data was read, the answer telegram is sent and the reader activates the green LED for about 50 ms. No visual activity of LED during write instructions. 3) Red LED: Status indicator Displays 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 transponder is 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 firmware The description for upgrading the firmware will be found in chapter 6 • Undervoltage operation of the reader (e.g. U < 8 V/DC) 10 deister electronic GmbH 30890 Barsinghausen Germany V19/07/04 RDL150 RS485/RS232 5.3 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: Yellow LED: Green LED: The rotatable switch (S5) must be turned to the right The rotatable switch (S5) must be turned to the left 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 position before 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 than 2 cm) the switch S7 must be actuated before the rotatable switch is turned. V19/07/04 deister electronic GmbH 30890 Barsinghausen Germany 11 RDL150 RS485/RS232 Installation Instructions 6.1 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. LCD monitors have a minimal influence on the read range. In particular the reader should be mounted on non-metallic material, such as plastic or wood. Metal screws (M6 - ISO 1207, 4762 or 7045) for mounting the reader have an insignificant influence on the read range. Note: With growing distance between reader and interference source the influence decreases. 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. 12 deister electronic GmbH 30890 Barsinghausen Germany V19/07/04 RDL150 RS485/RS232 6.2 Mounting Considerations The 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 simultaneously by two or more readers. min. 500 mm To ensure proper operation and optimal read/write range, take the following precautions: min. 500 mm Figure: Visualization of separation distances (vertical and back-to-back) 1. Mount all readers before tuning any of the readers 2. 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 transponder 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 two readers is acceptable. V19/07/04 deister electronic GmbH 30890 Barsinghausen Germany 13 RDL150 RS485/RS232 Upgrading Firmware To 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. 14 deister electronic GmbH 30890 Barsinghausen Germany V19/07/04 RDL150 RS485/RS232 • Start programming procedure by clicking 'Program'. • Program displays "Flash Loader Programming" while the green LED and the red LED are switched 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 process should run properly now. • If this update variation also fails, please contact your service partner or sales representative at deister electronic GmbH.
