Serial Server Quick Start Guide

For descriptive purposes this Quick Start Guide considers a typical configuration consisting of a PC connected via an Ethernet LAN to an ESP901 or ESP902 Serial Server connected to the RS-232 port of a serial device.

Hardware Setup

Figure 2. Typical Hardware Setup

Step 1: Connect the Serial Server to the network using a standard network cable.

Step 2: Connect the Serial Server to the RS-232 port on the serial device.

Note:

If the serial device is configured as a DCE use a straight-through serial cable. If the serial device is configured as a DTE use a crossover (null modem) cable.

Step 3: Set all the DIP switches to the OFF position.

Step 4: Apply power to the Serial Server.

Introduction

Software Installation

Using the CD included with the Serial Server, install the VLINX ESP Manager software on the configuring computer.

Serial Server Configuration

Step 1: Open the ESP Manager software. It will automatically search for any reachable (ESP90x) Serial Servers. A list of all Serial Servers connected to the LAN will appear in the Serial Server List window.

Step 2: Double click the desired Serial Server port on the list to bring up the Server Properties configuration screen.

Figure 3. The Server Properties Window

Step 3: Change the Server Properties as required.

Enable DHCP to allow the Serial Server to generate its own IP address

OR

Obtain appropriate static IP, Netmask and Gateway addresses from your Network Administrator

(recommended)

Set the Serial Port Mode property to RS-232 to match the serial device connected to the Serial Server.

Set Baud Rate, Data/Parity/Stop, and Flow Control to match the configuration of the serial device connected to the Serial Server port

Step 4: When the parameters have been set, click Update. Following the prompts in the dialogue boxes, Restart the Serial Server and Search all reachable servers again.
