1 General Information / Security Advice 1.1 Notes on the use of this documentation This user manual and integration guide uses different symbols to point out potentially dangerous situations. The following signs and symbols are used throughout the document. ATTENTION Declares a potentially hazardous situation. If this is not avoided, the product or something in its surrounding could be damaged.
2 Product Description The QuasarLR is an HF RFID reader/writer for demanding industrial applications, where high reading reliability, speed and extensive special tag features are needed. Highlights include a reading rate of up to 100 tag-IDs/sec and reading and writing data on tags without needing to address them individually. This allows applications directly at conveyor belts, in production machinery and in electric control cabinets. 2.

3 Power Supply and Electrical Specification The QuasarLR is powered using 24 V DC which are connected at the front of the device. If you do not use a power supply supplied by metraTec, please make sure that your own PSU provides a supply voltage of high quality. If possible, use a PSU with high precision/high speed linear regulator. If you use a switching PSU, please make sure that the switching frequency is > 500 kHz. Fig. 2: Power Connector Description (ref. Tab. 1) Connector Description X3.
4 Communication The QuasarLR offers two main options as a host interface – USB and optionally an Ethernet connection. The main advantage of the optional Ethernet interface lies in the very long cable length that Ethernet allows between the host computer or network switch and the reader in the field. Additionally, versions with WiFi and ZigBee are available on special request. 4.
5 Antenna Installation To send and receive data to and from the tags an appropriate HF RFID antenna (13.56 MHz, 50 Ohm) has to be connected to the reader. This is done via the BNC connector on the reader. To connect the antenna to the reader or multiplexer the devices are equipped with BNC jacks and the cables are equipped with BNC plugs at both ends.
ATTENTION – FCC/ISED Compliance To comply with FCC Part 15 rules in the United States / with ISED Rules in Canada, the device must be installed by a professional installer to ensure full compliance. The operator of the device and the installer are responsible to ensure that only certified systems are deployed in the United States / Canada.
6 Digital Input/Outputs The QuasarLR has 2 digital input pins and 4 digital output pins which can be be read or set via the reader. The input pins are optically isolated 24 V DC inputs as common in automation technology in general. Up to 25 mA are needed to set the input to "high". The output pins are 24 V high side switch DC outputs with a maximum current of 250 mA per pin. These can be used to directly power e.g. signal towers. In total a maximum current of 1000 mA for all pins is allowed.

7 External Status LEDs The reader features 3 external status LEDs indicated the operating state. The LEDs are listed from left (24 V power connector) to right (USB connector). Status LEDs LED E1 LED E2 LED E3 Farbe green* green* blue Status 24 V Power OK RF Output on Transponder detected Tab. 4: Meaning of the external LEDs * Revisions up to 1.1 have red LEDs instead of green ones.
8 Internal Status LEDs Internally, the reader is equipped with 2 LED bars for status display which might be useful for the advanced system integrator for setting up and analyzing the system's status. The LEDs can be reached by opening the upper housing half after removing the upper two screws. The LEDs are labeled on the circuit board. The LEDs of the status bar signals the status of the reader as listed in Tab. 5.
The VSWR LED bar signals the tuning of the antenna. The standing wave ratio should be better than 1:2, and there should be only green or at least orange LED lights active. Tab. 6 lists the LED colors.
9 Further Notes 9.1 Environmental Electronic devices like the QuasarLR are covered by the (German) ElektroG (electronic waste law) as well as the European WEEE directive and as such may not be disposed of by way of the normal household trash. Instead they have to be recycled properly. For you as our customer this is no additional burden, however, as you can send the device back to us for proper recycling.
9.3 Regulatory Information FCC / ISED (USA / Canada) NOTE This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment.
