Cables The 4-Port Serial MIM is shipped with a 1-to-4 conversion cable. One end of the
cable has a DB-100 connector for connecting to the module, and the other ends
have DB-50 (female) connectors for connecting to a synchronous/asynchronous
serial port cable.
You must order the cable you need to use with your 4-Port Serial MIM when you
order the module. To prevent damage to your router and to avoid voiding your
warranty, use only the appropriate cable offered by 3Com.
The end of these cables that connects to the conversion cable has a DB-50
connector. The type of network connector depends on the line type or the type of
device at the network end. There are four possible cables that you can use with
the module conversion cable. These cables are described in Table 31.
