6.2 System Overview
An automatic docking mechanism in the Compaq SmartStation docks the Compaq
LTE Elite Family of Personal Computers (Figure 6-1) or the Compaq LTE Lite
Family of Personal Computers (Figure 6-2). A Compaq LTE Lite must have a
SmartStation Adapter connected to it before it can dock. Refer to Appendix
D, "Docking and Undocking", for more information on using the SmartStation
Adapter.
NOTE: Early model Compaq LTE Personal Computers (not Compaq LTE Lite
models) such as the Compaq LTE 386s/20 cannot dock in the Compaq
SmartStation.
When the computer is docked, the 198-pin external options connector handles
the entire electrical interface (both power and signal connections) between
the computer and the expansion base.
The expansion base provides the computer with two drive bays, two expansion
board slots, built-in network capability, pass-through connections for
external equipment, a battery charger for a Compaq LTE Elite spare battery
pack, and other features. Refer to Section 6.3 for a list of the expansion
base features.
