Introduction Chapter 1: INTRODUCTION The VLINX Model ESP904 Quad-Port Ethernet Serial Server provides Ethernet to Serial connections for RS-232, RS-422 or RS-485 devices. 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 ESP904. The LAN becomes transparent to the serial device and the software running on the PC. Heart Beat Connection - selectable protocol ensures reliable communications in Virtual COM Port or Paired Connection modes. This feature restores the connections if communications are temporarily lost at either end due to loss of power or the Ethernet connection. Communication Modes The ESP904 enables communication with serial devices over a LAN or WAN.
Introduction To use this mode, the ESP904 must be set to either TCP/server or UDP/server with a designated communication port number. The virtual COM driver is the TCP or UDP client. 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 ESP904s and the LAN. Two ESP904s are connected to a network, one configured as a TCP or UDP client and the other as a TCP/UDP server.
Introduction ESP904 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 ESP904 Serial Server connected to the RS-232 port of a serial device. Hardware Setup Figure 1. Quick Start Hardware Setup Step 1: Connect the ESP904 to the network using a standard network cable Step 2: Connect the ESP904 to the RS-232 serial device.
Introduction ESP904 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 first ESP904 port on the list (4000) to bring up the Server Properties configuration screen. Figure 2. The Server Properties Window Step 3: Change the Server Properties as required.

Server Properties Configuration Chapter 5: CONFIGURING THE ESP904 SERVER PROPERTIES The VLINX Serial Server can be configured using any of four different user interfaces: the ESP Manager software, the Web Server, Console Mode or Telnet. The Server Properties described in this chapter can be changed from any of these user interfaces. Figure 26.
Server Properties Configuration Description of the Server Properties Figure 27. 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 gateway to the ESP904. If a DHCP server is not available on the network the ESP904 will time out after 10 seconds and the default values will remain. Note: A dynamic address assigned by the DHCP server may change if the ESP904 loses the Ethernet connection or power is removed. The host (client) communication software requests a connection to the specific IP address of the serial server.
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 Data/Parity/Stop Set this to match the data format used by the device connected when the Virtual COM mode is not being used. Flow Control The Flow Control setting must match the requirements of the device connected. Note: Select None when setting ESP Port 1 as RS-485 or 4-wire RS-422. TCP/UDP Protocol Select TCP (Transmission Control Protocol) or UDP (User Datagram Protocol) protocol. If the application does not require a UDP connection, select TCP.
Server Properties Configuration Serial Timeout Default for the Timeout property is 0, or no timeout. Setting Timeout to any value between 1 and 65535 seconds activates it. If Timeout is set to 5 seconds and the Serial Server is configured as a Server, the Client makes a connection and communications starts. If communications are ideal for 5 seconds the Serial Server will reset and make itself available for another client connection. TCP Alive Timeout The Serial Server monitors TCP activity.
Server Properties Configuration Force Transmit This field allows the user to set a maximum time limit between transmissions of data. The value set in this field multiplied by 100 ms determines the Force Transmit time. When the elapsed time reaches the time configured in this field, the TCP/IP protocol will pack the data currently in the serial buffer into a packet and send it out the Ethernet port.
Server Properties Configuration RS-232 – When this mode is selected and the server updated, the selected serial port will become an RS-232 serial port on the server. RS-422 – When this mode is selected and the server updated, the selected serial port will become an RS-422 serial port on the server. RS-485 – When this mode is selected and the server updated, the selected serial port will become an RS-485 serial port on the server.

RS-485 Connections APPENDIX C: RS-485 CONNECTIONS ESP904 DB-9 Pin-out in RS-485 Mode RS-485 Signal Name Direction RS-485 DB9M Pin Data B (+) In/Out DATA B (+) 3 Data A (−) In/Out DATA A (−) 4 Signal Ground --- GND 5 Figure 67. DB-9 Pin-out in RS-485 Mode Note: Some RS-485 devices are marked opposite the RS-485 standard, which defines the Data B line as positive relative to Data A during a Mark state before enabling the transmitter, and after transmitting before tri-stating.
RS-485 Connections To connect 4-Wire RS-485 devices, the RS-422 Mode can be used provided the ESP904 will be connected as a master in a single master system. If using multiple masters, the ESP904 cannot be used, as it does not tri-state the transmitter in RS-422 mode. 76 Appendix C Manual Documentation Number: ESP904-4513m B&B Electronics Mfg Co Inc – 707 Dayton Rd - PO Box 1040 - Ottawa IL 61350 - Ph 815-433-5100 - Fax 815-433-5104 – www.bb-elec.
