The dual serial ports are DB-50 connectors. (See Figure 2-20.) These serial ports can be configured
as DTE or DCE, depending on the type of serial cable being used.
Note If the dual serial port module is labeled with V2, as shown in Figure 2-20, then for optimum
performance, use the version of the cable with the part number ending in -02: for example,
72-0740-02 (DCE) or 72-0671-02 (DTE).
