Basic Operation of the R890
When power is supplied to the reader, the antenna in the reader will emit a continuous low-frequency RF field. When a card is placed within this field, the antenna inside the card will gather the energy present in the field to power the internal circuitry of the card. The card will then transmit its unique identification (ID) number to the reader. After receiving the signal, the reader verifies the validity of the signal. If the signal is valid, it will be decoded by the reader and sent in the appropriate output format to the host controller through data cables. The controller then determines what action to take in response to the information received from the reader.
R890 Card Presentation Test
Place the card parallel to the R890 extended range proximity reader and move it toward the reader until the card code displays on the controller screen. At this point, the card is read, decoded, data transmitted to the controller and the controller has responded accordingly. To read the card again, remove and re-insert the card into the reader's field.
R890 General Installation Notes
LED and "beeper" operations are programmed via the Centaur® access control software, if using another controller refer to appropriate instructions.
Do not use "twisted pair" with either output format.
Pull the orange wire low to illuminate the red LED.
Pull the yellow wire low to illuminate the green LED.
Pull both the orange and yellow wires low to illuminate the red and green LEDs, producing an amber color.
Pull the brown wire low to activate the "beeper".
Follow the recommended cable types and lengths listed in the “Technical Specifications”.
For open collector (non-terminated output), consult your system manufacturer for correct cable length and type.
R890 Mounting
Please consider the following when selecting a mounting location:
Avoid installing within 3m (10ft) of computer monitors or CRTs. The distance may vary depending on the monitor and CRT type.
Avoid installing near large metallic surfaces such as steel walls or chain-link fences.
Avoid installing in proximity to sources of broad spectrum EMI noise such as motors, pumps, generators, DC to AC converters, uninterruptible power supplies, AC switching relays and light dimmers.
Avoid installing in proximity to potential sources of RF signal transmitters such as cellular telephones and two-way radios.
