Getting StartedUDS-10 User Guide 2-112.5 ARP and TelnetThe unit’s IP address must be configured before a network connection is available. You areable to ARP an address into a CoBox/UDS device even if there is already an address in theunit. If the unit has no IP address, you can use Address Resolution Protocol (ARP) methodfrom UNIX and Windows-based systems to assign a temporary IP address. If you want toinitially configure the unit through the network, follow these steps:1. On a UNIX or Windows-based host, create an entry in the host's ARP table using theintended IP address and the hardware address of the unit, which is found on the productlabel on the bottom of the unit. Some UNIX hosts use colons “:” between hardwareoctets, and some use dashes “-“. All Windows hosts use dashes.arp -s 191.12.3.77 00:20:4a:xx:xx:xxNote: For the ARP command to work on Windows 95, the ARP table on the PC must have atleast one IP address defined other than its own.2. If you are using Windows 95, type ARP -A at the DOS command prompt to verify thatthere is at least one entry in the ARP table. If the local machine is the only entry, pinganother IP address on your network to build a new entry in the ARP table; the IP addressmust be a host other than the machine on which you are working. Once there is at leastone additional entry in the ARP table, use the following command to ARP an IP addressto the unit:arp -s 191.12.3.77 00-20-4a-xx-xx-xx3. Open a Telnet connection to port 1. The connection will fail quickly, but the unit willtemporarily change its IP address to the one designated in this step.telnet 191.12.3.77 14. Finally, open a Telnet connection to port 9999, and press Enter within three seconds to gointo Setup Mode. If you wait longer than three seconds, the unit will reboot and you willneed to perform step 3 again.telnet 191.12.3.77 99995. Set all required parametersNote: The IP address you just set is temporary and will revert to the default value when theunit 's power is reset unless you log into the unit and store the changes permanently. Refer tothe chapter on configuration for instructions on permanently configuring the IP address.
