DTE vs. DCE Operation
Figure 16 shows a port with one DB-25 connector that
can be configured for either DTE or DCE operation. The
configuration requires separate cables for proper sig-
nal routing in DTE or DCE operation. Figure 16 illus-
trates a DCE or DTE controller-selectable interface. The
DCE/
DTE
and INVERT inputs switch the port
s mode of
operation (Table 1).
The MXL1543 and MXL1544/MAX3175 can be connect-
ed for either DTE or DCE operation in one of two ways:
a dedicated DTE or DCE port with an appropriate gen-
der connector or a port with a connector that can be
configured for DTE or DCE operation by rerouting the
signals to the MXL1543 and MXL1544/MAX3175 using
a dedicated DTE cable or dedicated DCE cable. The
interface mode is selected by logic outputs from the
controller or from jumpers to either V
CC
or GND on the
mode select pins. A dedicated DCE port using a DB-25
female connector is shown in Figure 17. Figure 18 illus-
trates a dedicated DTE port using a DB-25 male con-
nector.
