Chapter 1 Introduction
Configuring the IP Address Chapter 2 IP Address Configuration Methods An IP address can be assigned to the device server using any of the following methods: • • • • • Setup Wizard “Discovers” the device and then provides a method for assigning an IP address. See "Configuring the IP Address with the Setup Wizard" on page 11. DHCP The device server’s default configuration is as a DHCP client. See "Configuring the IP Address with DHCP" on page 12.
• • The CD will be used on a system running Microsoft Windows operating system or a Unix operating system The device server’s MAC address is recorded for later use in assigning an IP address Procedure 1. Insert the Digi CD in the CD drive. 2. If the CD does not start automatically, double-click My Computer > CD ROM Drive > setup.exe 3. The wizard will automatically pop up. Click Next. The Digi application finds and lists all of the Digi devices on your network. 4.
1. Access the command line. 2. Issue the following command: arp -s ip-address mac-address Example arp -s 192.168.2.2 00-40-9D-00-00-00 Ping the Digi device using the IP address just assigned. ping 192.168.2.2 The ping will probably time out before there is a response from the device server. Wait a few seconds and then ping the device server again. The device server will respond indicating that the IP address has been configured.

Chapter 3 Setting Up RealPort (COM Port Redirection) What is RealPort Many serial devices, including barcode scanners and sensors, don’t have an Ethernet port. And even if they did, the applications that run them work on COM1. They know nothing of networking or TCP/IP. Many of these applications were written before TCP/IP and Internet were common. RealPort allows you to really network enable your device with our device servers. With a Digi device server, you can easily connect your device to the network.
2. Install the RealPort software on your PC. See "Installing RealPort on a System Running Microsoft Windows Operating System from the CD" on page 16. For UNIX RealPort software and documentation, see the Digi web site (www.digi.com). Configuring the Device Server for RealPort 1. Access the configuration by opening a web browser and entering the IP address in the URL address bar. 2. Log on as the root user (User Name root). The default password is dbps. 3.

Click the port to be configured. 3. Click Change Profile 4. Select any profile and Click Apply. 5.
TCP Sockets Profile This profile allows serial devices to communicate over a TCP network. The TCP Server allows other network devices to initiate a TCP connection to the serial device attached to the serial port of the Digi device server. The TCP Client allows the Digi device server to automatically establish a TCP connection to an application or a network. Note: If using the RFC 2217 protocol, do not modify the port settings from the defaults.
Note: About TCP and UDP Port Numbers Digi device servers use the TCP and UDP port numbering conventions described in the following table: For this connection type... Use this Port Telnet to the serial port 2001 (TCP only) Raw connection to the serial port 2101(TCP and UDP) You must ensure that the application or device that initiates communication with the device server uses these ports.
Printer Profile This profile allows you to connect a printer to a serial port. Use this profile if you intend to print using the lpd protocol on your UNIX system. Note: Refer to your UNIX User Guide for tips on configuring the print spooler on your UNIX system. Terminal Profile This profile allows you to connect to a terminal to the serial port. Custom Profile This profile allows you to see all settings and set them accordingly.
