Summary
Configuration
This document explains how TESLA Control Panel can access
multiple remote TESLA Recorders with only a single modem
call. This is much more convenient than the traditional method,
which requires a separate call to each recorder.
There are four main preparation steps.
Using a device called a LAN modem (in this case, a Rugged
Comm RS400) makes this possible. The LAN modem has several Ethernet ports to which the recorders are connected and
one phone line. The user establishes a PPP dialup connection to
the modem and then accesses the Recorders with TESLA Control Panel using their assigned IP on the Ethernet Network.
3. Configure the PC for Dialup Networking
1. Configure the LAN modem (PPP & Ethernet)
2. Configure the TESLA Recorders
4. Configure TESLA Control Panel
Note:
The example above shows only 2 TESLAs but this version of the
modem has 4 Ethernet ports so 4 devices can be supported
including a mix of relays.
Our multi-function relays and recorders provide smart solutions to your protection, monitoring and
control needs.

Accessing Multiple Remote Recorders on a Single Modem Call
1. Configure the LAN Modem Using the RS-232 Port to Access the User Interface
Attach a terminal (or PC running terminal emulation software, ie. HyperTerminal)
to the RS-232 port. The terminal should be configured for 8 bits, no parity operation at 57.6 Kbps. Hardware and software flow control must be disabled. Select a
terminal type of VT100.
When the terminal is connected, selecting any key on the keyboard prompts the
user to enter the username and password.
The modem is shipped with a default administrator username “admin” and password “admin”.

Login: maintenance (lower case)
No password is required. If you are asked for one, there is a mistake
in the login name, if anything is misspelled in maintenance you cannot backspace.
Select Enter to get another Login Prompt and try again.
When you have successfully logged in, you are presented with the
Maintenance Menu.
Note:
The * next to some of the items. You can only modify these items
through the use of this Maintenance Menu.
For the purposes of this Applications Note we are concerned with
changing the IP Address of the TESLA.
Note:
Menu items are selected by typing the number of the item at the
command line at the bottom of the screen. In this case we want Item
1 as shown.
After 1 is entered you will see messages that the System is halting
etc.
Then the current parameters are displayed and you are asked if you
want to change the IP Address.
[N/y] # y, you must enter a “y” then you will be asked to enter the
new IP, then you will be asked if you want to change the IP to the
value that you entered, and you must enter “y” again in order to make
the change. This is repeated for the Subnet Mask and Default Gateway, we will use the IP as shown for the TESLA in our example
above and the Subnet Mask should match the value we entered in
the Server of 255.255.255.0, and finally the Gateway IP should be
that of the Server, 192.168.99.1.
This process needs to be repeated for each TESLA connected to the
Server.

3. Configuring the PC for Dialup Networking
In order for the PC to connect to the Modem and thus the Remote Recorders, a
Dialup Networking entry must be created. The instructions in this section pertain
to Windows XP, but the steps are similar for most versions of Windows.
Select Start>Connect to>Show All Connections (and from the left Panel) select
Create a New Connection.
When the Network Connection Wizard appears, click Next.
In the next screen select Connect to the Network at my Workplace. This entry includes: Connect to a business network (using dial-up or VPN)…..
So this is the type of connection we want to create.
Select Next.
The next screen presents two options Dial-Up and VPN and of course we want
Dial-Up. Select Next again.
Now it will ask which Modem on your PC that you want to use to dial out. Select it
from your list and click Next.

This must match the Username and Password used assigned in the PPP Configuration of the Rugged Comm Modem.
You can place a check in the Save User/Password box depending on your company’s policy on Usernames and Passwords. You also have the option on this
screen for Me only or Anyone.
In the next screen give the connection a meaningful name such as the name of
the substation where the Modem and Recorders are installed.
Finally in the next screen you will be asked for the phone number of the Modem
in the Substation.
Select Next and choose to Create the Connection for all users.
Select Next thru other screens until you get to Finish.
At this point you will be presented with the connect screen which asks for your
User Name and Password.

4. Configuring TESLA Control Panel
Start TESLA Control Panel and on the right hand side
under the Select IED panel, select Add New.
Here you can enter the IED Name, this most likely be the
Recorder Name in the Substation and keep in mind you
will be addressing more than one recorder (the main reason for the installation of the Rugged Comm
Modem/Server).
Enter the IP Address of the particular recorder you have
designated using the IP assigned to it in Configuration
Step 2. Configure the TESLA Recorder click OK.
Repeat this step for each of the Recorders that are attached to the Rugged Comm.
Testing and Using the System
Testing the system consists of dialing to the LAN Modem
(Rugged Comm) and ensuring that the Recorders connected to it can be reached.
1. Locate and open the Dial-Up Networking Entry created
earlier (in this example Substation 01 Rugged Comm).
This can be found in Start>Connect to> and selecting it
from the list in the drop down that appears.
2. Note: The first time this dialog box opens select
Properties at the bottom.
And verify that the Type of Dial-up server I am Calling is
PPP.
After that is confirmed select OK to close the dialog box.
Now enter your Username and Password to match the
PPP username and Password configuration of the
Rugged Comm.
Click Dial and wait until the Modem answers and
negotiates a connection (you should see a connection
icon appear in your system tray).

3. Bring up a DOS Window by selecting Start>Run>Cmd. In the resulting
DOS Window type “Ping and the IP Address of the Modem (in our
example 192.168.99.1) you should see Successful Ping. The same
can be done for the IP Address of each of the Recorders (again in our
example 192.168.99.2 and 192.168.99.3).
You should now be able to communicate with any of the TESLAs connected to the Rugged Comm using TESLA Control Panel. To test this, follow these steps:
1. Do not hang up the connection.
2. Start TESLA Control Panel and select one of the recorders you set up
in Configuration Step 4 and select Connect. You are now connected to
the remote recorder and can use TESLA Control Panel normally.
4. If you wish to connect to another recorder in the substation before
hanging up you can simply select it from TESLA Control Panel’s drop
down list and select Connect.
5. Once you are done communicating with the remote Recorders, you
can hang up the LAN Modem connection by right-clicking the communication icon in the system tray and selecting Disconnect.
Summary
Following these steps should allow you to configure TESLA Control
Panel to access multiple TESLA Recorders on a single Modem call.
3. To disconnect from the recorder, go to the Main Screen of TESLA
Control Panel and select Disconnect. This only disconnects TESLA
Control Panel from the recorder, it does not hang up the LAN Modem
connection.
