Two-Way Communication

Telephone Connection

An RJ-45 connector (which accepts RJ-11 connectors) is lo-
cated behind the flap on the upper end of the computer. It
allows you to connect the computer to phone lines if an op-
tional internal modem was ordered. This is not an Ethernet
connection.

Ethernet Connection

Although all 6620 Computers have Ethernet capability, the
connection is physically located on the single dock or on the
multidock.

Serial Communication

A 9-pin D-subminiature connector (COM1), located behind
the flap on the upper end of the computer is used for serial
communication with peripheral devices.

Infrared Communication

An infrared port, located at the lower end of the computer,
permits two-way wireless communication between the com-
puter and IrDA-compatible peripheral devices.
Remote Antenna Connector
Also at the lower end of the computer, just below the in-
frared connector, is a special terminal-to-dock antenna con-
nector. This can connect the computer to a remotely located
antenna when the computer is docked.

Docking Connector

This connector, located on the bottom of the computer,
mates with a connector in docking devices. Most signals
are carried on these connectors, including Ethernet, serial,
and parallel communication signals, and control voltages.
This allows the dock to act as a hardwire interface between
the computer and a variety of peripheral devices. A battery
charging voltage is also supplied to the computer via the
docking connector.
