The 1-Port Serial SIC cable is a serial port cable. There are four possible cables that
you can use with the 1-Port Serial SIC. You must order the cable you need from
3Com when you order the interface card. To prevent damage to your router and
to avoid voiding your warranty, use only the appropriate cable supplied by 3Com.
The end of these cables that connects to the router has a DB-50 connector. The
type of network connector depends on the line type or the type of device at the
network end. These cables are described in Table 17 and are illustrated in
Figure 14, Figure 15, Figure 16, and Figure 17.
