13: Connections
Chapter 10: Device Ports described how to configure and interact with an EMG port connected to
an external device. This chapter describes how to use the Devices > Connections page to connect
external devices and outbound network connections (such as Telnet or SSH) in various
configurations.
An EMG port attached to an external device can be connected to one of the following endpoints:

Another device port attached to an external device

Another device port with a modem attached

An outgoing Telnet or SSH session

An outgoing TCP or UDP network connection
This enables the user to set up connections such as those described in the next section. You can
establish a connection at various times:

Immediately. These connections are always re-established after reboot.

At a specified date and time. These connections connect after the date and time pass.

After a specified amount of data or a specified sequence of data passes through the
connection. Following reboot, the connection is not reestablished until the specified data
passes through the connection.
Typical Setup Scenarios for the EMG unit
Following are typical configurations in which EMG connections can be used, with references to
settings on the
Devices > Connections
and
Device Ports > Settings (1 of 2)
web pages.
Terminal Server
In this setup, the EMG acts as a multiplexer of serial data to a single server computer. Terminal
devices are connected to the serial ports of the EMG unit and configured as a Device Port to
Telnet out type connection on the Devices > Connections page. The users of the terminals can
access the server as if they were connected directly to it by local serial ports or a console.
