Chapter 3: Configuration
3. Configuration
There are no DIP switch or jumper settings that need to be modified in order to operate the basic functrions of the A/B Switch.
There are, however, several parameters related to Ethernet remote access/control and the automatic switching features that are
configurable. These settings are described later in this manual.
NOTE: The internal jumpers and DIP switches inside the A/B Switch have been pre-configured at the factory and should not be
changed from their default settings. They are shown here for reference only.
