Getting Started UDS-10 User Guide 2-1 2. Getting Started This section describes all the procedures for configuring your unit. For a short version, see the Quick Start Guide.
Getting Started 2-2 UDS-10 User Guide 2.1.3 Port Number Every TCP connection and every UDP datagram is defined by a destination IP address and a port number. For example, a Telnet application com monly uses port number 23. A port number is similar to an extension on a PBX system.
Getting Started UDS-10 User Guide 2-3 2.3 Methods of Assigning the IP Address The unit's IP address must be configured before a network connection is available. You have the following options for assigning an IP to your unit: Method Description DHCP A DHCP server automatically assigns the IP address and network settings.
Getting Started 2-4 UDS-10 User Guide 2.3.1 DHCP The unit ships with a default IP address of 0. 0.0.0, which automatically enables DHCP. Provided a DHCP server exists on the network, it will assign the unit an IP address, gateway address, and subnet mask when the unit boots up.
Getting Started UDS-10 User Guide 2-5 AutoIP can be disabled by setting the unit’s IP address to 0.0.1.0. This setting enables DHCP but disables AutoIP. 2.4 DeviceInstaller You can manually assign the IP address using DeviceInstaller software, which is found on the product CD.
Getting Started 2-6 UDS-10 User Guide 2.4.2 Assign IP Address and Network Class Click the Start button on the Task Bar and select Programs Device Installer Device Installer . The Device Installer window displays. Figure 5 - DeviceInstaller Window 1.
Getting Started UDS-10 User Guide 2-7 3. In the Enter IP Address to assign field, enter the unit’s IP address in XXX.XXX.XXX.XXX format. 4. In the PC Network Class section, select th e class (subnet mask). (Most users select Class C). 5. Click the Set IP Address button.
Getting Started 2-8 UDS-10 User Guide 2.4.4 Add the Unit to the Manage List Now add the unit to the list of similar Lantronix devices on the network so that you can manage and configure it. 1. Click the Search the network for devices icon. The Search Network window displays.
Getting Started UDS-10 User Guide 2-9 6. Click the Back button to return to the DeviceInstaller window. The DeviceInstaller window now lists all of the devices in the group, including the unit you are setting up. The hardware address and firmware release number for the unit display.
Getting Started 2-10 UDS-10 User Guide 2.4.5 Opening a Conf iguration Window 1. Click the Manage icon . The Device Management window displays. Figure 10 - Device Management Window 2. Do one of the following: Note: To assign Expert settings and Security setti ngs, you must use the Setup Mode window in a Telnet session.
Getting Started UDS-10 User Guide 2-11 2.5 ARP and Telnet The unit’s IP address must be configured before a network connection is available. You are able to ARP an address into a CoBox/UDS device even if there is already an address in the unit.
Getting Started 2-12 UDS-10 User Guide 2.6 Serial Port Login If you want to initially configure the unit through a serial connection, follow these steps: 1. Connect a console terminal or PC running a terminal em ulation program to your unit's serial port.
Configure UDS-10 User Guide 3-1 3. Configuring the Unit You must configure the unit so that it can communicate on a network with your serial device.
