Setting carriage return-line feed
Unless commanded otherwise, Telnet transmits a line feed character only (no carriage return) to the connected
switcher when you press the <Enter> key. This is the correct setting for SIS communication with the switcher.
The Telnet set crlf command forces Telnet to transmit carriage return and line feed characters when <Enter> is
pressed; however, if crlf is set, the SIS link with the switcher does not function properly.
Closing the link to the switcher
]
To close the link to the switcher, access the Telnet prompt by entering the escape sequence (<Ctrl+
>). At
the Telnet prompt, enter close.
Help
For Telnet command definitions, enter ? at the Telnet prompt.
Exiting Telnet (Quit command)

Subnetting, a Primer
A subnet is a subset of a network — a set of IP devices that have portions of their IP addresses in common. It is
not the purpose of this manual to describe TCP/IP protocol in detail. However, some understanding of TCP/IP
subnetting is necessary in order to understand the interaction of the DXP PLUS switcher and the mail server
gateway. To understand subnetting at the level required to install and operate the DXP PLUS switcher, you must
understand the concepts of a gateway, local and remote devices, IP addresses and octets, and subnet masks
and octets.
Gateways
The DXP PLUS switcher can communicate with the e-mail server that it uses for e-mail notification directly (if they
are on the same subnet), or the communication can be routed via a gateway (a computer that provides a link
between different subnets).
IP addresses and octets
Valid IP addresses consist of four 1-, 2-, or 3-digit numeric sub-fields, called "octets," which are separated by dots
(see figure 118). Each octet can be numbered from 000 through 255. Leading zeros, up to three digits total per
octet, are optional. Values of 256 and above are invalid.
Typical IP Address:
192.168.254.254
