4.0 INSTA L L AT I O N
The Model 2011 is designed to be used in pairs , with one unit
installed between an asynchronous DTE and a synchronous DCE on
either end of a synchronous communication link. Figure 3 illustrates a
typical Model 2011 installation.

4.1 CONNECTING THE ASYNCHRONOUS PORT
The asynchronous port of the Model 2011 is a DB-25 female and
is configured as "DCE". Therefore it wants to talk to a DTE device such
as a terminal or PC. The Model 2011 may be plugged directly into the
DB-25 serial port of a DTE or connected via "straight through" cable.
4.2 CONNECTING THE SYNCHRONOUS PORT
The synchronous port of the Model 2011 is a DB-25 male and is
configured as "DTE". Therefore it wants to talk to a DCE device such
as a modem or multiplexer. The Model 2011 may be plugged directly
into the DB-25 serial port of a DCE or connected via "straight through"
cable.
