Sometimes, a switch is used on an isolated network that does not have a DHCP server built into it. These are great switches for portability and cost, but without a server, each device connected to it will generate it's own IP address and may not see each other. The way around this is to set up a static IP on each device connected to the switch. For this example, we'll use a Spark HDMI and a PC running Windows 7, connected to a simple un-managed 5 port switch
1. Install the NDI-HX driver on the Windows 7 PC (from here)
2. Connect the Spark and the PC directly into each other via standard Cat6 networking cable
3. Open up a web browser and navigate to 192.168.100.168 to pull up the Locallink (failsafe) admin page
4. When prompted, enter your username and password (by default, it's "admin" for both fields on the Spark, without quotes.
5. You'll be presented with the standard Admin page for the Spark.
6. Navigate to the Administration tab.
7. Scroll down to the Ethernet section and click the drop-down arrow.
8. Change the IP address drop-down type from Dynamic to Manual.
9. For the IP address, use anything in the 192.168.100.x range (for Connect Spark SDI and Connect Spark HDMI), except for 1, 255, or 168. (for the example, I used 192.168.100.10 - For Connect Spark Pro, establish an IP address in the APIPA address block (such as 169.254.0.254)
10. For the Gateway, use 192.168.100.1
11. For the Netmask, use 255.255.255.0 - For Connect Spark Pro use netmask of 255.255.0.0
12. Select Apply to save changes.
13. On your Windows 7 PC, click Start, select Control Panel, and then choose Network and Sharing Center.
14. By now, Windows should have identified your network type and probably says it has no internet access. Click the Connection type.
15. Click Properties
16. Select Internet Protocol Version 4, and click Properties
17. Choose the option for "Use the following IP address" and uses the same information as posted. NOTE: You can use any IP for the address except .1, .255, .168, or whatever the IP you set for the Spark (.10 in our case. Notice I put .20). Press okay when done, then close any remaining windows.
18. Launch NDI Studio Monitor (it would've been installed along with the drivers back in step 1)
19. Right click on the background to choose your source.
