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:
• 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.
