1 Basic information
1.1 Introduction
The interface options enable this stationary reader with integrated controller to be connected
directly to a PC, processor or controller.
1.2 Applications
The reader was especially designed for applications where it is necessary to read and write several
transponders at the same time from different distances.
• Control of incoming goods and dispatch
• Event ticketing
• Operating data collection
• Lending processes
• Paperless operations such as electronic delivery papers, invoices, receipts

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)
