NI ISM-7413 Ethernet Integrated Stepper User Manual

6. Next, enter the subnet mask as 

255.255.255.0

7. Leave 

Default gateway

 blank. This prevents your PC from looking for a router on 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

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 

Discovery will look for additional devices on you network. Once you have told Drive Discovery 

which device is yours, it automatically enters the device IP address in the IP address text box so 

that you are ready to communicate.

Option 2: Connect a Device Directly to Your PC

1. Connect one end of a CAT5 Ethernet cable into the LAN card (NIC) on your PC and the 

other into the device. You don’t need a special crossover cable; the device automatically 

detects the direct connection and make the necessary physical layer changes.

2. Set the IP address on the device to 

10.10.10.10

 by setting the rotary switch to position 0.
