GLX-RSS-4 User Manual FCC Part 15.21 - Information to the user/installer Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. FCC 15.105(b) - Information to the user/installer This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules.
GLX-RSS-4 User Manual RADIATION EXPOSURE STATEMENT The device meets the exemption from the routine evaluation limits in section 2.5 of RSS 102. This equipment should be installed and operated with a minimum distance of 20 centimeters between the radiator and users. L'appareil satisfait à l'exemption des limites d'évaluation de routine de la section 2.5 de RSS 102. Cet équipement doit être installé et utilisé à une distance minimale de 20 centimètres entre le radiateur et l'utilisateurs.
GLX-RSS-4 User Manual 2. Connector Pin-Out The Radar Surveillance Sensor RSS-4 uses single or dual connector to interface external systems: circular M12 IP68 connector with 8 positions for Ethernet connection with PoE supply option and additional M12 IP68 12 positions connector with additional interfaces and connectivity options. Picture 1. Radar view on the back side of the device Details of the 8 and 12 position M12 connectors are shown on Picture 2.

The power supply for the Radar is provided on this pin.
GLX-RSS-4 User Manual 3. RSS-4 Radar Sensor Installation The Surveillance Radar Sensor installation should be done by skilled personnel to avoid any damage to the device. Radar Sensor can be pole mounted or mounted to the fixed object. It is also possible to mount Surveillance Radar Sensor to the tripod for mobile applications. Fixing of the Surveillance Radar Sensor is done by four M6 screws on the back side of the device.
GLX-RSS-4 User Manual It is also recommended to use threadlocker glue for better lock of screws. Radar assembly was tested for vibrations and screw locking with Loctite 243 medium strength threadlocker glue. In all mounting variants, the Surveillance Radar Sensor should be solid fixed to the holder and holder should be implemented solid to reduce vibrations and movements of the device. In case radar is moving or strong vibrations are present on the device false detections of void targets are possible.
GLX-RSS-4 User Manual 4. Coverage area design guidelines For the best radar positioning and optimal coverage area design there are few basic factors to take in to account when designing coverage area: 1. Radar sensor coverage area for the RSS-4 sensor 2. Minimal target return signal to be detected 3.
GLX-RSS-4 User Manual Picture 5. Radar coverage area - vertical plane Minimal detectable target RSS-4 radar sensor detects moving and stationary targets in the radar field of view by transmitting modulated electromagnetic wave in 24 GHz frequency range (Kband), and measuring the frequency shift of the reflected electromagnetic wave.
GLX-RSS-4 User Manual • • • Walking human: 0,75 m2 (-1,25dBsm) Average car: 4 to 8 m2 (6 to 9 dBsm) Average truck: 6 to 10 m2 (7,78 to 10dBsm) Average RCS measurement is averaged in reflected angle and time. RCS for most targets is not constant for all incident and reflected angles and it is not constant in time as the consequence of the target moving. Typical measurement of radar crosssection for the standing human in all angles is shown on the picture 6. Picture 6.
GLX-RSS-4 User Manual Shape of the monitored area The shape of the monitored area that must be covered by the radars will mostly affect radar arrangement and quantity required to cover the area. In some cases, it will be possible to cover the area with single radar, in some cases more radars will be required to cover the area.
GLX-RSS-4 User Manual be larger, and it can be simple calculated from basic geometry. To decrease minimal detection distance tilt down of the sensor can be used. It is recommended to keep tilt down in range from 0° to 9°. • When using wireless links to connect radar sensors to control center or some other radio frequency equipment is used on the location it is recommended to move antennas of this equipment minimum 2m from the RSS-4 radar sensor.
GLX-RSS-4 User Manual 5. Initial radar setup The unit configuration is done through the web-based user interface. To access the user interface, connect the radar to the Ethernet network, and then access the radar interface through a web browser of a PC computer that is connected to the same Ethernet network. Default factory settings for connection to the radar are: Default IP address: Default password: Configuration interface: Boot time: 192.168.0.208 radarpwd http://192.168.0.
