Startup Option Switches
There are eight switches, SW2-1 through SW2-8, that control the startup options. Table 2-1
specifies the available startup options and corresponding switch settings.
Autorestart Switch
Autorestart is controlled by switch SW2-8 (see Figure 2-5). The settings for switch SW2-8 are:
1. DOWN (on) - Autorestart is not enabled. Use this setting if you do not wish to use
autorestart or if battery backup is not installed. When using the ON position for SW2-8,
be sure you set the Battery Enable switch to DISABLE.
When SW2-8 is ON, if power is lost, the autorestart feature will not restart the program
that was running prior to the powerfail condition. Instead, the boot loader (or VCP
routine) will execute.
2. UP (oft) - Autorestart is enabled if battery backup is installed and the Battery Enable switch
is set to ENABLE. If power is lost and memory was sustained, autorestart will automatically
restart the program that was running prior to the powerfail condition. With no battery
backup installed, you will get a self-test error when you switch the computer on.
