The DCE/DTE strap is located on the top side of the 1088/D pc board
(See Figure 9, below). The arrows on the top of the strap indicate the
configuration of the X.21 port (for example, if the DCE arrows are point-
ing toward the DB-15 connector, the X.21 port is wired as a DCE).
Change the DCE/DTE orientation by pulling the strap out of its socket,
rotating it 180º, then plugging the strap back into the socket. You will see
that the DCE/DTE arrows now point in the opposite directions, showing
the new configuration of the X.21 port. To close the case, fit the 2 halves
together snugly and snap them back in place.
