Network Connection Considerations
Figure 2-19 shows the network connections of the four-port serial module adapter cables.
Figure 2-19
Four-Port Serial Port Adapter Cables
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).
