User Selectable DIP Switch Settings for Main CPU Bay
13 Factory Default Settings
As the Allegiant system is shipped from the factory, certain features are placed in a default configuration. The installer can select some of these features at the time of system installation/configuration. Generally the default configuration represents the simplest mode of operation, allowing the user to become familiar with the system before any advanced features are selected. The default settings are described in the sections below.

•Switch 4 of S1001
This switch is used to set the communication baud rate which the Allegiant will use when connected to a LTC 8712 Series Console Port Expander. It is only applicable when DIP switch 3 is in the ON position. When set to ON, the baud rate will be 57,600 bps (recommended setting). When OFF, the baud rate fol- lows the setting determined via DIP switch 8 of the lower CPU DIP switch. If switch 8 of the lower DIP switch is OFF, the baud rate defaults to 19,200 bps. If switch 8 of the lower DIP switch is ON, the user programmed baud setting is used, but the user setting must be 19,200 baud or higher in order to operate.
