4. RS485 Interface
Most 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 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: twisted pair, cable-cross-section at least 0,22mm² (AWG 24)
differential-mode characteristic impedance 100-120 Ohm

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)

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: The rotatable switch (S5) must be turned to the right
Yellow LED: The rotatable switch (S5) must be turned to the left
Green 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 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.

6 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.
)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 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.
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.

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.
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 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 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 two
readers is acceptable.

7 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.

• 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.
