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.

NOTE

Declares notes for the user as well as other useful information, where no

harmful or dangerous situations can be expected.

1.2 Security Advice

The QuasarMF HF RFID Reader was not designed for use in dangerous environments. Using

this product in applications where a failure could directly results in severe injuries or death

(“high risk activities”) is not permitted. This includes but is not limited to applications in

nuclear facilities, flight control systems, life support systems or weapon systems. The

manufacturer denies the suitability of this device for such scenarios.

1.3 Export Restrictions

The QuasarMF contains components that underlie US Export restrictions. It is therefore

forbidden to export the product to countries that are on the US trade embargo list. The

same applies to any countries that are on the EU embargo list.

1.4 Further Documents

While this documentation explains the electrical and mechanical characteristics of the

QuasarMF RFID Reader, it might be useful to also read the metraTec Protocol Guide, which

explains the protocols used to control the reader in full detail.

We also offer general information about how to set up the connection of the reader to the

antenna for optimum system performance in our HF Antenna Integration Guide.

3 Power Supply and Electrical Specification

The QuasarMF is powered using 24 V DC which are connected at the front of the device

(X3). 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 > 00 kHz.

4 Communication

The QuasarMF offers several options as a host interface. Each version has a USB connection.

Additionally, versions with Ethernet, WiFi or ZigBee are available, the latter two on special

request.

4.1 USB Driver Installation

The basic option for connecting the QuasarMF with your host PC is using the USB

connection every reader has.

1. Connect the reader with a 24V DC power source as described before.

2. Connect the reader with a PC using a USB cable (X4).

3. Install the USB driver. metraTec offers the needed driver including Installation

Guides for Windows XP and Windows 7 (as downloads from metraTec's website).

Technical Documentation metraTec QuasarMF Page 8 of 14

Antenna Connection

To send and receive data to and from the tags an appropriate HF RFID antenna (13. 6 MHz,

0 Ohm) has to be connected to the reader. This is done via the BNC connector on the

reader (X1).

Since the design of HF antennas can be a task requiring expert knowledge, metraTec RFID

Solutions offers a range of standard antenna types for HF applications which are compatible

to the QuasarMF. Further, we offer an antenna design service for custom designs. Most

antennas come equipped with standard BNC connectors which can be directly connected to

the QuasarMF. In cases in which a different antenna geometry or connector is needed

please contact [email protected].

To connect the antenna to the reader or multiplexer the devices are equipped with BNC

jacks. Necessary cables are therefore equipped with BNC plugs at both ends. When

connecting antennas with multiplexers or readers please keep in mind that the cable has a

signal dampening effect reducing the HF power reaching the antenna. If long cables are to

be used in connection with one or more multiplexers the reading range can be reduced

measurably. Using higher quality cables can reduce the power loss in cases in which this is

important. Recommended cables with different lengths can be ordered from metraTec as

accessories.

ATTENTION

Always connect an 0 Ohm antenna as described above first, before

powering the device. Powering the reader without an appropriate 0 Ohm

load for a longer time could damage the reader permanently.

6 Digital Input/Outputs

The QuasarMF 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 2 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 2 0 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. Outputs are equipped with internal overcurrent and

overtemperature shutdown.

The pins X2.1 and X2.2 are connected directly to the power supply input, i.e. the applied

voltage is 24 V DC. This can be used for power supply of e.g. sensors, etc. The power of

these pins is only limited by the power of the power supply used.
