System Serial Security
To protect against unauthorized access to system operation DIP switch 1 of SW1 on the Power Supply board lets
you enter a 6-digit security code before the system will respond to a serial command (only applies to consoles
having form numbers 8469X0-260, 230, & -460). If enabled, the default serial security code is 000000. The
security code itself can be changed with a serial command (see “Function Code: 504” on page 31). Consoles are
shipped from the factory with this switch in the open (disabled) position.
See Figure 15 on page 17 for location of this switch. Figure 19 shows the switch in the closed position, enabling
the security feature.
Switch 2 and Switch 3 are not used and can be in any position.
