The DCE/DTE strap is located on the top side of the 1082 PC board (see
Figure 10). The arrows on the top of the strap indicate the configuration
of the X.21 port (for example, if the DTE arrows are pointing toward the
DB-15 connector, the X.21 port is wired as a DTE). Change the DCE/
DTE orientation by pulling the strap out of its socket, rotating it 180º, then
plugging the strap back into the socket. To close the case, fit the two
halves together snugly and snap them back in place.
