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 Windowsmay be

used along with the HyperTerminalprogram. To start and configure

HyperTerminalfollow 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.

Chapter 1: Configuration and Operation

Example of port setting under HyperTerminal.

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.
