ES1A Mini Ethernet to RS-232 Converters provide simple and cost- effective solutions for connecting RS-232 devices to Ethernet networks. ES1A converters make it easy to connect serial printers, copiers, building automation, retail, point-of-sale, warehousing and banking equipment directly into Ethernet networks. ES1A converters support virtual COM port, console management, TCP and UDP socket, serial bridge, modem emulation and custom connections.
Introduction Communication Modes ES1A Ethernet to RS-232 converters allow you to connect 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.
Introduction Other Communications Modes ES1A Converters also feature the following communications profiles: Modem Emulation Mode allows you to configure the serial port to operate as if it is a modem. For legacy applications where a serial device is set up to communicate through a modem, the serial device can now be connected to the ES1A and communication occurs over the network.
Package Checklist ES1A Ethernet to RS-232 Converters are shipped with the following items included: The ES1A module A printed version of this user manual A printed version of the ES1A Quick Start Guide CD-ROM disc with B&B discovery software RealPort drivers for Windows 98/ME/2001/XP/NT 4.0/Vista this user manual in PDF format a Quick Start guide in PDF format Figure 2.
Hardware Overview Indicators, Switches and Connectors Link Integrity LED (Yellow) When the yellow LED located on the Ethernet jack is illuminated it indicates that a connection (link integrity) has been established between the converter and a node on the network. Network Activity LED When the green LED located on the Ethernet jack is flashing it indicates that data is being sent across the network.
Serial Port Connector The Serial Port Connector is a DB-9 male connector (configured as a DTE) supporting RS-232 serial communications including TD, RD, TRS, CTS, DTR, DCD, DSR and GND signal lines. Use a standard serial cable if connecting to a DCE;...
1. Check the contents of your ES1A package. It should contain… The ES1A module A printed version of this user manual A printed version of the ES1A Quick Start Guide CD-ROM disc with discovery software, RealPort software, this manual, Quick Start guide 2.
Getting Started 6. Configure the ES1A In the Configuration, Serial Ports page select the Port Profile you require for use with your application (E.g. RealPort for virtual COM port, TCP Server, UDP server, Serial Bridge, etc) Configure the serial port settings for the selected Port Profile (E.g. In TCP Sockets select client or server, TCP port numbers, etc.) Also configure baud rate, data bits, etc in Basic Serial Settings.
Before you can begin the configuration of your ES1A you must know its IP address to access it with a web browser. Once you have access to the Configuration and Management Interface via a web browser you can reset the IP address using static IP addressing, if necessary.
Page 22
Configuring the ES1A If you need to change the IP address of the ES1A, you can accomplish this using the discovery software, or you can open the Web Configuration and Management Interface and do it there. (See Configuring Network Settings later in the next chapter.) 1.
Using the Web Configuration and Management Interface The ES1A Ethernet to RS-232 Converter can be configured using the Configuration and Management Interface via a standard web browser such as Internet Explorer or Firefox. Logging In 1. Before you can begin configuring your ES1A Converter, you must login to the Configuration and Management Interface.
Using the Web Configuration and Management Interface Using Tutorial and Help You can access the ES1A Tutorial by clicking Tutorial on the Configuration and Management homepage. Clicking Help on any page of the Configuration and Management Interface opens topics specific to that page. After logging in, if there is no activity for a period of time your session may time out.
Using the Web Configuration and Management Interface Figure 7. Network, IP Settings Page IP Settings The IP Settings section allows you to select between dynamic or static IP addressing. The ES1A’s default setting is Obtain an IP address automatically using DHCP, or dynamic IP addressing. When the ES1A is first connected it will try to obtain an IP address automatically.
Using the Web Configuration and Management Interface Consult the web-based tutorial and/or your network administrator for more information on Network Services and Advanced Network settings. Configuring the Serial Port The Serial Port Configuration page displays information about the serial port on your ES1A, including its description, its profile (operating mode) and serial settings (baud rate, data bits, parity, stop bits).
Using the Web Configuration and Management Interface Figure 8. RealPort Select RealPort to implement the use of virtual COM ports. This allows you to map a COM port on a PC to the serial port on your ES1A. Using RealPort software (included with the ES1A) you create a virtual COM port on the PC.
Using the Web Configuration and Management Interface TCP Sockets Select TCP Sockets to implement Direct IP Mode using TCP. When using TCP Sockets your converter can be configured as a TCP server or TCP client. TCP Server Settings If your ES1A is configured as a TCP server, other network devices can initiate a TCP connection with the serial device connected to the ES1A serial port.
Using the Web Configuration and Management Interface Figure 10. TCP Client Settings Consult the Tutorial and online Help for more detail. UDP Sockets Select UDP Sockets to implement Direct IP Mode using UDP protocol. When using UDP Sockets your converter can be configured as a UDP server or UDP client.
Page 30
Using the Web Configuration and Management Interface Figure 11. UDP Server Settings UDP Client Settings If your ES1A is configured as a UDP client you can automatically distribute serial data from you ES1A to many devices at the same time. This is sometimes referred to as Data Distribution or UDP Multicast.
Using the Web Configuration and Management Interface Serial Bridge Select Serial Bridge to implement Paired Mode (also called serial tunneling). This allows serial devices connected to two ES1A converters to communicate across the network. The two ES1A converters automatically connect to each other.
Using the Web Configuration and Management Interface Configuring Alarms and Notification The ES1A can be configured to generate alarms and send notification emails based on the occurrence of specific events. Events include the states of some RS-232 handshake (GPIO) lines and the detection of specified character patterns within the serial data stream.
Using the Web Configuration and Management Interface Alarm Destinations Alarm Destinations allows you to specify where to send alarm notification emails, their priority and subject title. Type the information into the Mail to email address, CC address, set the Priority and type in the Subject line. To send an SNMP trap, select Send SNMP trap to following destination when alarm occurs and type the destination IP address for the SNMP trap.

RealPort is a COM port redirector program that allows you to add and remove virtual COM ports on your PC and update the RealPort software. Virtual COM ports allow you to set up a connection between your PC and the device connected to the serial port on your ES1A via an Ethernet network connection using TCP/IP.
Using RealPort Adding a Virtual COM Port using RealPort Windows 2001/XP/Vista: 1. Locate the RealPort driver software on the CD you received with your ES1A. 2. Find the RealPort setup.exe file for your PC’s operating system. 3. Start the setup.exe file. The RealPort Setup Wizard Welcome dialog appears.
4. Select the Remove an Existing Device, then click Next. The Select Device to Remove dialog appears listing the IP Address, MAC Address and Model of all devices on the network. To identify your ES1A compare the MAC address listed with the MAC address on the label on your ES1A.
