CSU's COM port for daisy chain connectivity. (The
SNMP LAN Adapter includes the cable that is needed
to attach it to the CSU.) The AUX port connector is a

For daisy-chaining an AUX port
to a COM port, a 25-pin-to-8-pin,
cable is required and the
appropriate configuration
options (Com Use and Aux Use)
must be set to Daisy. Whenever
the cable is connected or
disconnected, you should
change the Daisy selection to
ensure that the correct
parameters have been
negotiated for the link layer.
