Chapter 5. Host Connectivity
707021-001
You can connect to an IP Host by entering one of the following in the “Connect to:” field and
pressing :
• class number or class name – If a host in this class is available, and the device is authorized
to connect to the specified class, the connection will occur.
• DNS name – This is a known and authorized TELNET host name in the TCP/IP network.
The name may be up to 64 characters. If the host is available, and the device is authorized
for “Dynamic Access” to IP Hosts in the Device Profile Assignments panel, the connection
will occur. Full explicit names should end with a period, otherwise the configured Domain
name value will be appended to the DNS name.
• IP address – This is a known TCP/IP host address. It is four octets with each octet separated
by a dot. For example, 192.82.252.236 is an IP address in decimal format. If the host is
available, and the device is authorized for “Dynamic Access” to IP Hosts in the Device
Profile Assignments panel, the connection will occur.
When connecting to a specific IP Host using the DNS name or IP address, optional parameters
are allowed as follows:
• Line ID – If TCP/IP is enabled on multiple lines, you can dynamically connect through a
specific line by entering the line ID as the 2nd parameter. Otherwise, the first line configured
for TCP/IP will be used for establishing the connection. For example,
“192.82.252.236,TRC2” forces the TELNET host connection to be made through line TRC2.
This is true only for DNS “Dynamic Access” to IP hosts, it is not true for classes.
• TCP Port – Normally, all connections will be made to TCP port 23, standard for TELNET.
To select a TCP port, enter a specific TCP port as the 3rd parameter. For example,
“192.82.252.236,TRC2,6000” forces the TELNET host connection to be made through line
TRC2 using TCP Port 6000. If no specific line is entered as the 1st parameter, a TCP Port
may still be entered by omitting the first parameter. For example, M5,6000 may be entered
to force a connection for the class M5 using TCP port 6000. Two commas are needed if
using a DNS name or an IP address. In this case, the default line ID would be used.
The following function key is available in addition to those described in the section titled
“Host Connection Menu”:
3-Ping – This function key provides access to the Ping feature panel. The Ping Function is
described in more detail in the section titled “Ping Feature Panel”.
TCP/IP Host Connectivity Configuration and Management
Configuration – The utilities needed to define TCP/IP (TELNET) Host Connections are
described in under ASCII Host Protocols in this document.
Displays are given the ability to dynamically connect to IP hosts via the Resource Authorization
Matrix in the display’s Device Profile.
Management – Refer to the common Configuration and Management for Dynamic
Host Connections.
