Safety Instructions

• The device may only be used for the intended purpose designed by for the manufacturer.
• The operation manual should be conveniently kept available at all times for each user.
• Unauthorized changes and the use of spare parts and additional devices which have not been sold or recommended by the manufacturer may cause fire, electric shocks or injuries. Such unauthorized measures shall exclude any liability by the manufacturer.
• The liability-prescriptions of the manufacturer in the issue valid at the time of purchase are valid for the device. The manufacturer shall not be held legally responsible for inaccuracies, errors, or omissions in the manual or automatically set parameters for a device or for an incorrect application of a device.
• Repairs may only be executed by the manufacturer.
• Installation, operation, and maintenance procedures have to be carried out by professional and qualified personnel.
• Use of the device and its installation must be in accordance with national legal requirements and local electrical codes.
• When working on devices the valid safety regulations must be observed.
• Before touching the device, the power supply must always be interrupted. Make sure that the device is without voltage by measuring. The fading of an operation control (LED) is no indicator for an interrupted power supply or the device being out of voltage!

NOTE:

• Wearers of pacemakers
  • Although this device does not exceed the permissible limits for electromagnetic fields, you should keep a minimum distance of 25 cm between the device and your pacemaker and not stay in the immediate vicinity of the device or the antenna for long periods of time.

Commissioning of the device

IMPORTANT NOTICE In order to comply with the requirements of the European Radio Equipment Directive (RED) 2014/53/EU article 3 (3), points (d), the following points must be taken into account for the product ID MR103-E:

• When using the network interface (Ethernet), it may be necessary to create at least one user to enable various functions such as changing the configuration. The user and the password MUST be set by the person who puts the device into operation on first use before it is logically connected to a network or by an authorized entity within a network where access is limited to authorized entities.
• When security and/or network assets (keys, certificates, ethernet configuration parameters) are transferred via network interface (Ethernet) TLS encryption must be used to secure the communication.

Cyber Security related Firmware Updates

IMPORTANT NOTICE: In order to comply with the requirements of the European Radio Equipment Directive (RED) 2014/53/EU article 3 (3), points (d), you are required to register in the FEIG download area under https://www.feig.de/en/ and subscribe to notifications for cybersecurity-related firmware and software updates for the product ID MR103-E.

Firmware downgrade

IMPORTANT NOTICE: A firmware downgrade to older major release versions is not possible in order to prevent old major versions with known cyber security vulnerabilities from being executed on the device.

Installation

Interface Overview and Connections

Depending on the reader variant, different connections and interfaces are available.

Interface designation

Tab 4: Connector description

Antenna connection ANT1

There is an SMA socket on the circuit board or on the housing for connecting the external antenna.

NOTE:

• The antenna must be adjusted to the value 50 Ω (50 Ω L 15°).
• The optimum operating quality of the antenna should be in the range QB = 10…20. To determine the operating quality, the antenna must be supplied with a 50 Ω source, e.g. a network analyzer or a frequency generator.
• When connecting an antenna, make sure that it does not exceed the permissible limit values of the national regulations regarding radio equipment.
• The maximum tightening torque of the SMA sockets is 0.45 Nm.

DC Voltage on antenna connector ANT1

A DC voltage can be applied from the reader to the ANT1 antenna connection. This DC voltage can be used to supply an LED, for example.

NOTE:

• The DC voltage is only designed for low currents. The DC voltage (6,9 V± 1 V) can be loaded up to a maximum of 5mA.
• Only antennas that are suitable for DC voltage and do not short-circuit the DC voltage may be connected.
• When connecting other devices (e.g. VSWR meters), make sure that they are also suitable for DC voltage.
• This DC voltage is not suitable for supplying the automatic antenna tuner ID ISC.DAT.

• The device may only be supplied by a power source in accordance with EN 62368-1 Chapter Q.1 Power sources of limited power or with a power supply unit certified in accordance with NEC Class 2/LPS.
• For more information on available power supply units, see Accessories.

Connector for external Power Supply Unit

X2: RS232 Interface (ID MR103-A)
The transmission parameters can be configured via software protocol.

Connector X2 / Pin Assignment

X3: USB-Interface (ID PR103-USB / ID MR103-USB, USBC)
The USB interface is connected via socket X3 (ID PR103-USB / ID MR103-USB / -USBC). The assignment is standardized. The data rate of the reader is limited to 12 Mbit (USB Full Speed). A standard USBC cable can be used.

NOTE: Maximum length of the USB cab e: ≤ 3 m

X4: Ethernet-Interface (ID MR103-E)

• The reader has an integrated 10/100 base-T network interface with standard RJ-45 connection. The connection is made via X4 and has automatic crossover detection in accordance with the 1000BASE-T standard.
• For structured cabling, at least CAT5 category cables should be used. This guarantees problem-free operation at 10 Mbps or 100 Mbps.
• A prerequisite for using the TCP/IP protocol is that each device on the network has its own IP address. All readers have a factory-set IP address.
• The transmission parameters can be configured via software protocol.
