Automatic Frequency Selection Mode (All DIP Switches OFF (up))

<Default Configuration> The RF modem is designed to automatically select and continuously optimize the performance of its radio channel. The radio channel is monitored to ensure it is providing low error rates necessary for successful radio transmission. In the event that the error rate rises, the RF modem will autonomously change to a new channel. There are 12 non- overlapping channels.

Australia only: In order to comply with Australian regulations, all modems intended for use in Australia are pre-configured to operate on 6 channels and DIP Switches are disabled.

Manual Frequency Selection Mode

To restrict the operation of the RF modem to a subset of the 902-928 band, the user may acti- vate a manual selection mode that allows the radio to automatically choose the best channel within a grouped subset of the 12 available channels. This is enabled by the 8-position DIP switch on the master unit. These settings allow the RF modem to operate on the optimal chan- nel in one of three subsets: LOW 4, MID 4 or HIGH 4.

Site Survey Mode (DIP Switch 4 is ON (down))

In this mode the RF modem can perform a site survey. With this mode activated the radios send and receive at 100% capacity by transceiving self-generated simulated data. The installer can monitor the Link Quality display to assess channel quality while optimizing antennae orienta- tion. The installer can manually select each channel to evaluate performance and identify the best channels for operation. By identifying channels with poor performance it is possible to identify possible interferers and use "Manual Frequency Selection Mode" to avoid portions of the band or select a fixed operating frequency.

Important Note: Ethernet traffic does not get transported while the RF modems are in Site Survey Mode.
