Infrared
A line-of-sight pass-through opening in the dock permits
infrared (short-range wireless) communication between the
docked computer and certain peripheral devices, such as a
printer. The distance between the dock and the device must
be less than one meter.
Keyboard
The 6-pin Mini-DIN connector directly supports PS/2 or PC
AT keyboards through an adapter cable. Keyboard signals
are available on the docking connector to permit the use of
an external keyboard when the computer is docked.
Auxiliary Port
The AUX connector is a 15-pin male D-Sub connector that
can serve as a third 3-wire COM port providing TXD, RXD,
and GND. This connector also provides a general purpose
open-collector output on pin #11 and a general purpose
TTL/CMOS compatible input on pin #10.
AC Power
AC power is available through an ac power adapter. This
allows the dock to be operated from standard electrical out-
lets using an appropriate power cord to the adapter.
Docking and Undocking
Instructions on how to insert and remove a 6620 Computer
from a dock are found in the 6620 Computer User’s Guide.
