The central processing unit

General

There are various types of central processing units (CPU) available for the

BEETLE /20 POS system: the 80486DX2/66 type and a central proces-

sing unit suited to the technical progress.

The central processing unit consists of a PC-compatible board. In addition

to the components and interfaces typical for a PC, this has POS-specific

functional units, such as non-volatile memory (NV RAM), the memory card

logic system, the cash drawer interface and support for the uninterruptible

power supply (UPS) function.

The central processing unit also has a separate slot that can be used for a

SVGA, VGA, LAN, ASYNC or SVGA or VGA/LAN submodule.

The connection panel contains the sockets for the external peripherals. To

find out the layout of the connections on the central processing unit, refer
