The Model 2X2 is a satellite terminal. It must be connected to a Model 5X1, 4X1 or 3X1 to function. Video is not supported on this model. In a transaction intense environment, providing a back-up image on the secondary drive allows transaction data to be readily recovered if there is a primary disk failure. When terminals are powered down, they are kept running with minimal power so that when powered backup, they do not require a complete operating system reload if storage retention is enabled.
Control is returned to the next sequential instruction.
External notification, such as a modem call or pushing the mode button, also causes the 4693 to awaken. Currently, the 4690 Operating System is the only operating system enabled to enact programmable power. The 4690 Operating System has an inactivity default that causes the terminal to go to sleep mode after 15 minutes of inactivity. The terminal can be brought back to operational mode within 10 seconds of becoming necessary for a customer checkout. The 4690 OS uses Novell DSG's FlexOS Version 2.32 operating system as the base.
