1.0 Introduction
The STE-10 Serial Access Unit is a low cost, compact, serial
access server or terminal server for connecting asynchronous serial
devices (RS-232) over Ethernet (10Base-T) using a TCP/IP protocol
stack. The STE-10 may operate in either a client mode or as a server,
allowing connection of serial data directly over a LAN or WAN.
Configuration may be performed either via the DB25 pin RS-232 port
with an ASCII terminal or via Telnet and Ethernet connection on the
RJ-45 LAN port. The serial port is DTE, which allows direct
connection to DCE equipment such as Modems. For connection to
other DTE equipment such as a PC or terminal, a NULL Modem or
crossover cable is required. One is provided with the unit.
1.1 Features
•Low cost, compact design.
•Serial connection over Ethernet.
•Operates in either server or client mode.
•Complete TCP/IP protocol stack (OSI Network Layer 3).
•Provides packetization of serial data.

1.3 Configuration
Before any Ethernet connection is made to the STE-10, the
device must have a valid IP address, which is accessible through the
network. Initial IP setting is accomplished with a terminal connection
to the RS-232 serial port. Connect a serial terminal to the RS-232 port
of the STE-10 at 9600 baud, 8 bits, no parity and 1 stop bit. Since the
STE-10 is DTE and a terminal is also DTE, please use the provided
crossover cable. Set the configuration switch on the STE-10 to
"SETUP" and apply power.
If a serial terminal is not available, a PC with Windowsmay be
used along with the HyperTerminalprogram. To start and configure
HyperTerminalfollow these simple steps:
Using your mouse, browse to HyperTerminal; Start =>Programs
=>Accessories =>Communications =>HyperTerminal.
Double-click the "Hypertrm.exe" icon. Enter a name (such as
STE-10) and choose an icon for the connection. When the "Connect
to" dialogue box appears, click the down arrow on the "Connect
using:" pull-down tab and select "Direct to COMx" where "x" is the
COM port number that will connect to the STE-10.
Click the "OK" button and set the COM port parameters for; 9600
baud, 8 bits, no parity, 1 stop bit and no flow control. Refer to the
following page graphic.

An initial message like the one below will be displayed while the
port checks whether it is connected to a modem, followed by the main
configuration menu display.
