NXC-8160 User’s Guide

In a serial communications connection, generally a computer is DTE (Data Terminal 
Equipment) and a modem is DCE (Data Circuit-terminating Equipment). The NXC-8160 is 
DCE when you connect a computer to the console port. 
The pin layout for the DB-9 connector end of the cables is as follows.

Configuration Backup & 

Restoration

Make a copy of the NXC-8160’s configuration. You can put it back on the 

NXC-8160 later if you decide to revert back to an earl

i

er configuration.

IP Multicast

IP multicast is used to send traffic to a specific group of computers. The 

NXC-8160 supports versions 1 and 2 of IGMP (Internet Group 

Management Protocol) used to join multicast groups (see RFC 2236).

Time and Date

Get the current time and date from an external server when you turn on 

your NXC-8160. You can also set the time manually. These dates and 

times are then used in logs.

Logging and Tracing

Use packet tracing and logs for troubleshooting. You can send logs from 

the NXC-8160 to an external syslog server.
