25. this subnet Using DHCP If you want to use your device on a network where all or most of the devices use dynamic IP addresses supplied by a DHCP server set the rotary switch to F When the device is connected to the network and powered on it will obtain an IP address and a subnet mask from the server that is compatible with your PC However you will not know what address the server assigns to the device The NI Stepper Configuration Utility can find your device using the Drive Discovery feature as long as your network isn t too large When the device connected to the network is powered on select Drive Discovery from the Drive menu to launch the Network Interface Dialog dialog box Figure 9 Network Interface Dialog Dialog Box amp Network Interface Dialog S Local Host IP Netmask BASEL 255 255 255 0 169 254 130 368 255 255 0 0 192 168 109 1 255 255 255 0 Selectthe host interface to search and click OK Cancel x Normally Drive Discovery only detects one network interface card NIC and selects it automatically If you are using a laptop and have both wireless and wired network connections a second NIC may appear Please select the NIC that you use to connect to the network to which you ve connected your device Then click OK Drive Discovery notifies you as soon as it has detected a device If you think this is the correct device click Yes If you are not sure click Not Sure and Drive Disc
26. ual Option 1 Connect a Drive to Your LAN If you have a spare port on a switch or router and if you are able to set your device to an IP address that is compatible with your network and not used by anything else this is a simple way to get connected This technique also allows you to connect multiple devices to your PC If you are on a corporate network check with your system administrator before connecting anything new to the network He or she should be able assign you a suitable address and help you get going Figure 8 Example Network Configuration NIC PC Switch LAN lt gt or lt r gt ISM Router Many networks use dynamic addressing where a DHCP server assigns addresses on demand The address you choose for your device might get assigned to something else by the DHCP server at another time Once you ve chosen an appropriate IP address for your device set the rotary switch according to the address table above If none of the default addresses are acceptable for your network you can enter a new table of IP addresses using the NI Stepper Configuration Utility If your network uses addresses starting with 192 168 0 the most common subnet you will want to choose an address from switch settings 4 through E Another common subnet is 192 168 1 If your network uses addresses in this range the compatible default selections are 1 2 and 3 If your PC address is no
