Introduction Chapter 1: INTRODUCTION VLINX Models ESP901 and ESP902 Ethernet Serial Servers provide Ethernet to Serial connections for RS-232, RS-422 or RS-485 devices. The ESP901 features a single serial port and the ESP902 features two serial ports. The serial ports can be accessed over a LAN/WAN using Direct IP Mode, Virtual COM Port, or Paired Mode connections. The 10/100 Mbps Ethernet connection auto-selects 10BaseT or 100BaseTX and indicates the type of connection with a bi-color link light.
Introduction Features 2 • Multi-interface serial ports o ESP901 and ESP902 Port 1 software selectable for RS232, RS-422, RS-485 (DIP Switch selects Console Mode) o ESP902 Port 2 is RS-232 only • 10/100 Mbps Ethernet with Auto Selection • LAN and WAN Communications • TCP or UDP Client or Server operation - configurable • Software Support - Windows 98/ME/2000/2003/XP/NT 4.
Introduction Communication Modes The ESP901 and ESP902 Serial Servers enable communication with serial devices over a LAN or WAN. Serial devices no longer are limited to a physical connection to the PC COM port. They can be installed anywhere on the LAN using TCP/IP or UDP/IP communications. This allows traditional Windows PC software access to serial devices anywhere on the LAN/WAN network.
Introduction Paired Mode Paired Mode is also called serial tunneling. In this mode any two serial devices that can communicate with a serial link will be able to communicate using two Serial Servers and the LAN. Two Serial Servers are connected to a network, one configured as a TCP or UDP client and the other as a TCP/UDP server. When setting up the server the remote IP address section must contain the address of the client.
Introduction 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.
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.
Introduction Step 5: Re-enter Server Properties to verify the changes have taken effect, or to view/change the configuration of other ports. Each port must be configured separately.

Server Properties Configuration Chapter 5: CONFIGURING THE SERIAL SERVER PROPERTIES The VLINX Serial Server can be configured using any of four different user interfaces: the ESP Manager software, Console Mode, Telnet or the Web Server. The Server Properties described in this chapter can be changed from any of these user interfaces. Figure 29.
Server Properties Configuration Description of the Server Properties Figure 30. ESP Manager Server Properties Window Server Name This field displays the name that has been assigned to the Serial Server. A new Server Name of up to 16 characters can be entered. If more than one Serial Server is connected on the LAN it is recommended that a new name be assigned to each.
Server Properties Configuration address, net mask, and gateway to the Serial Server. If a DHCP server is not available on the network the Serial Server will time out after 10 seconds and the default values will remain. When DHCP is enabled, the IP Address, Netmask and Gateway fields become inaccessible and cannot be changed by the user. Note: A dynamic address assigned by the DHCP server may change if the server loses the Ethernet connection or power is removed.
Server Properties Configuration Netmask The default LAN netmask is configured for a Class C address. The user may change this. Default is 255.255.255.0 Gateway The Gateway IP address allows users to access the Serial Server from outside the LAN. MAC Address The MAC address is fixed and cannot be changed. It is assigned in the factory. Every Ethernet device manufactured has it own unique MAC address. Version & Date The currently loaded version of the firmware, and when it was released, is shown here.
Server Properties Configuration Flow Control The Flow Control setting must match the requirements of the serial device connected. Note: Select None when setting the port as RS-485 or 4-wire RS-422.

RS-232 Connections RS-232 DTE Loopback Connections Figure 65. Loopback Connections for RS-232 For Transmit and Receive loopback, connect only those lines. When Flow Control setting on the Serial Server is set for RTS/CTS, those lines must be looped. Usually DTR and DSR must also be looped. The Flow Control setting for the program must match the Server settings. The CD connection is needed by some terminal programs to simulate Carrier.
