14 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.

14.1 User Selectable DIP Switch Settings for Main CPU Bay

NOTE After changing any of the following switches, the system must either be powered OFF and ON or reset using the keyboard (see user function 15).

14.1.1 Upper CPU DIP Switch S1

System CPU modules contain three (3) 8-position DIP switches. The settings of the upper DIP switch do not need to be changed from their factory default positions except when using a Console Port Expander accessory unit or if a problem is encountered when downloading new firmware into the CPU. For reference, the functions are as follows:

DIP Switch Number	Factory Default Setting	“Upper” S1 DIP Switch Function
1	OFF	Not Used
2	OFF	Not Used
3	OFF	Console Expander Use
4	OFF	Console Expander Mode
5	OFF	Boot Mode
6	OFF	Not Used
7	OFF	Not Used
8	OFF	Not Used

•Switch 1 and 2 of S1

These switches are not used in these systems and should be left OFF.

•Switch 3 of S1

This switch should be set to ON if an LTC 8712 Series Console Port Expander is connected to the Allegiant’s console port. This selection can also be set using either the MCS or the PC-based GUI Software package.

•Switch 4 of S1

Use this switch to set the communication baud rate that the Allegiant will use

when connected to a LTC 8712 Series Console Port Expander. It is only applica- ble 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 follows 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.

•Switch 5 of S1

In the ON position, this switch is used to force the CPU into a “boot” mode so it is ready to accept a download of an operating system program via its console port. This setting should not be changed unless a problem has been encoun- tered while attempting to download a new operating system program. When

this mode is enabled, the baud rate is fixed to 115200 and hardware handshake is ON.

•Switch 6, 7, and 8 of S1

These switches do not currently provide user selectable options and should be left OFF.
