Connecting Via Modem
Upon first dialing into the DL100, a user is presented with the unit answer string. By default, this
string is “Data-Link”. This string can be changed to indicate the specific application of this
device.
The previous table contains the default passwords configured on the DL100. It is recommended
that a system administrator change these passwords and keep them recorded in a secure location
thereafter.
Note: When a specific password is defined as blank or null, access via that password is disabled.
After entering an appropriate password, the DL100 will present an acknowledgement and the user
will be connected to the appropriate command processor. Once connected to the Command
Processor, the user has the same capabilities as if connected via serial port.
Connecting Via Telnet
Before using the DL100 via Ethernet for the first time, it is necessary to assign an IP address via
serial or modem connection. For typical command mode actions, TCP port 23 will be used.
Following is a table of the other TCP ports allowed on the DL100 and their functions.
PORT Function
21 Internal FTP server, reserved for future use.
23, 2001 Telnet to local command port.
210 n The n corresponds to the serial port number to connect a pass-through
connection to. For example, port 2101 connects to I/O1.
220 n The n corresponds the serial port number with which to perform a real-time
socket connection. For example, 2203 connects to FILE3.
2205 Telnet to alarms file real-time socket.

Because the same connection processes are used with both Telnet and modem connections, it is
possible to follow the same steps outlined above in the Connecting via Modem section when
connecting with Telnet.

The DL100 status screen is this unit’s one-stop informational source. Most of the information that
a user would need to know about the unit is available through this display. This section outlines
this data and highlights why it is useful.
