Igangkjøring av enheten
VIKTIG MERKNAD 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
VIKTIG MERKNAD: 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
VIKTIG MERKNAD: 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.
Installasjon
Housing version
- The readers are designed for indoor applications.
- Wall and under-counter mounting are possible with the optionally available mounting kit.

Fane 4: Koblingsbeskrivelse
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
En 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:
- 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.
- Denne DC voltage is not suitable for supplying the automatic antenna tuner ID ISC.DAT.
