EtherPath® SS-1R Single Port Serial Server
Quick Start Guide – Telnet Server Mode
This document guides the new user through configuration of an EtherPath® single port
serial server and demonstrates “Telnet Server mode”, in which the serial port of a remote
device is accessible via an ethernet connection.
Figure – Configuration for Telnet Server Mode, with Example IP Address on EtherPath
Requirements
. One EtherPath unit and knowledge of basic TCP/IP networking
2. PC with a wired ethernet connection, any modern web browser, and telnet
3. Client device capable of RS-232 serial communication
4. LAN cable, either straight-through or crossover, to connect PC to EtherPath LAN port
5. Appropriate cable to connect the EtherPath serial port to client device. This cable would
be identical to the one used to connect the device directly to a PC.
Step-by-Step Procedure
1: Open the box and note the contents: The EtherPath single port serial server, power
adapter and CDROM containing manual and Application Notes. Power up the EtherPath.
2: Configure the PC for use on the default LAN subnet of the EtherPath. Use the IP
address 92. 68. . 00 with a Subnet Mask of 255.255.255.0.
3: Connect PC to EtherPath's LAN port, open
a browser (Internet Explorer, Firefox,
Chrome, Safari), and enter http:// 92. 68. .
(NOTE that “http” is used, not https)
The EtherPath Setup screen should appear
as in Figure 2:

4: Click on Configure LAN from the menu and change the Mode to be Telnet Ser er, as shown
in Figure 3: All other LAN parameters may remain at the default values.

Click the Sa e button near the bottom of the screen to make the change active. A Ser er
Status Message screen will appear while the unit reboots. Wait several seconds for the
reboot to complete, then click the “Back” button to return to the prior screen.
5: If the EtherPath serial port settings (Baud Rate
= 9600, Data Bits = 8, Flow Control = NONE,
Stop Bits = , Parity Bit = NONE) do not match
the client device, click on Configure Port from
the menu and modify the serial port configuration
of the EtherPath, shown in Figure 4, to match that
of the client device.
If settings were changed, click the Sa e button
near the bottom of the screen to make the changes
active. A Ser er Status Message screen will
appear: Clicking the “Back” button returns to the
prior screen.
6: Connect the RS-232 cable between the serial
port of the EtherPath and the serial port of the
client device. Open a telnet session to port 3000
of 92. 68. . . Note that the EtherPath is
configured by default to listen on port 3000, not the standard elnet port 23.
Testing the Link
With the link established, the Telnet session should interface to the client device's serial
port with the same functionality as if the PC were connected directly to the serial port of
the client.
