Step-by-step Guide

3. Step-by-step Guide
The following chapters will guide you step by step through preparation, installation and activation of
the RAy3 link:
• Pre-installation check out
• Installation (Chapter 4.)
• Advanced configuration (Chapter 5.)
• Troubleshooting (Chapter 8.)
Pre-installation Checklist
Default settings for L and U units are chosen to allow delivered units to automatically establish a link
without unpacking RAy3 units from the box. It is enough to open the boxes and power both RAy units
up (by PoE or DC power supplies). It allows users to comfortably set up basic parameters necessary
for the installation in the lab and thus shorten the time on the tower or roof to a minimum. Following
text provides a guide how to optimally arrange the workplace, how to setup the link and which parameters
are good to be set up before the installation outside.
Default factory settings define the initial link to be established on the most narrow channel, strongest
modulation and lowest available Tx power (in RAy3 case those are 3.5 MHz channel, QPSK_S modu-
lation and Tx power = -30 dBm). Complete default settings are described in section 10 Technical
parameters.
Note
RAy3 default factory settings allow to install both units on the mast and establish the short link
without prior manual configuration. Just the distance has to be very short due to Tx power set
to the minimum for the unit (-30 dBm on RAy3-17 and RAy3-24). Typically, Tx power has to
be increased to a reasonable level (or even to a maximum) before link alignment.
