International for detailed instructions for Repeater configuration It is a free download from www digi com support documentation Also G3 Technologies can assist and in some cases may be able to supply pre set configuration files for Repeater and Repeater End Node configuration There are a number of other advanced functions that can be configured on these radios using the X CTU configuration utility but they generally require a more thorough understanding of the unit s function and should be done only by qualified personnel Digi s User Manual has detailed information about the function and configuration of advanced radio features NOTE that when using the G306C Wireless Modem with Wireless 1 0 units from G3 Technologies the G306C may not be able to utilize advanced configuration options Refer to the Wireless I O User s Guide for supported Radio Configuration options Antenna and RF Considerations The Rio Link Wireless Modem G306C operates in the ISM 900MHz or 2 4GHz frequency bands At these frequencies the RF signal is able to travel a considerable distance line of sight LOS At the higher frequencies the RF signal does not bend around obstacles like VHF and lower frequency RF signals Obstacles in the line of sight are generally the key consideration when evaluating the radio communications path For short distances of less than a few miles obstacles such as trees and buildings can often be overcome by raising the antenn
