• users
• WiFi password and behavior
• TX and RX frequencies (if known in advance)
• Higher TX power (to be ready for antenna alignment) – see section “Important” below
Note
This setup can be used for link configuration, however full radio performance can't be expec-
ted (high modulations, full TX power range, etc.) because standard conditions between units
(antenna interface, polarization planes, free space attenuation) are not met inside the box.
•
• High RF Output power does not necessarily lead to better RX signal quality, because the
receiver input can be saturated with too strong signal - see
• Until a WiFi password is set, red light periodically flashes together with green light - see
Section 1.5, “Status LED ( S )”
Important
Maximum secure TX power for RAy units inside the box is 0 dBm. Higher TX power risks
the damage of sensitive input circuits!
•
• If you need to configure higher TX power to be ready for antenna alignment during installation
on the mast, first you have to turn units in to position where waveguides are not heading to
each other, so reasonable attenuation is ensured. Secure is for example to put RAy units
in parallel in to a direction without any metal material in front of the microwave beams (it
could reflect waves back to units).
• Maximum time, that units can be powered up inside the box is 10 minutes (standard room
temperature expected). Longer time may lead to the unit overheat! If more time is needed
for configuration, units have to be unpacked from boxes.
3.2. Service access
The RAy3 link is supplied with a default configuration of access parameters:
For Ethernet access through RJ45 or SFP ports:
• Unit L has the service IP address 192.168.169.169 and mask 255.255.255.0
• Unit U has the service IP address 192.168.169.170 and mask 255.255.255.0
For WiFi or Ethernet access via USB/WiFi or USB/ETH adapter:
• Both units have service IP address 172.17.17.17 and mask 255.255.255.0
For Ethernet access through RJ45 or SFP ports an IP address has to be set on your PC that is within
the mask, e.g. 192.168.169.180. For WiFi or USB/ETH access an IP address for laptop or mobile or
tablet is set automatically by DHCP (enabled by default).
Then open the HTTP or HTTPS configuration interface, e.g. https://192.168.169.169 or ht-
tp://172.17.17.17
Access is allowed over HTTP, HTTPS or SSH.
The default username and the password is "admin" (it is strongly recommended to change it).
See
Configuration > Link settings > Service access > USB accessories
chapter for detailed information.
The Antenna Alignment Web Tool can also be used for antenna direction alignment. It can be accessed
via a web browser utilizing IP addresses with „/tk“ at the end (e.g. http://172.17.17.17/tk for WiFi or
USB/ETH adapter or http://192.168.169.169/tk or http://192.168.169.168/tk for ETH1/ETH2 ports).
