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 Mac running OS X.
1. You'll first want to install the latest NDI-HX driver on the Mac (https://www.newtek.com/ndihx/products/)
2. Connect the Spark and the Mac directly into each other via standard Cat6 networking cable - *Note - This will require a crossover cable connection for your Mac.
--------------------------------------------------------------------------------------------------------------
- If you own a MacBook, you may want to create a new network location. This will allow you to use the static IP address for certain networks and not others. Further instruction on this specific process can be sourced here: How to Configure Network Locations in OS X.
- From the Apple menu, select System Preferences.
- Select Network.
- From the sidebar, select an active network interface. For our purposes today, you'd want to select "Ethernet".
- Click Advanced.
- Select TCP/IP.
- From the Configure IPv4 menu, select Manually.
- In the IPv4 Address field, use anything in the 192.168.100.x range, except for 1, 255, or 168. (for the example, I used 192.168.100.20 - For Connect Spark Pro, establish an IP address in the APIPA address block (such as 169.254.0.254). For the Subnet Mask, use 255.255.255.0 - For Connect Spark Pro use netmask of 255.255.0.0
- Click OK.
- Click Apply.
At this point you should be able to access your Connect Spark interface. If the steps above were successful and you wish to establish a separate Static IP address on your Spark (to be used with switches without DHCP support), please continue on to the instructions below:
-------------------------------------------------------------------------------------------------------
1. You'll be presented with the standard Admin page for the Spark.
2. Navigate to the Administration tab.
3. Scroll down to the Ethernet section and click the drop-down arrow.
4. Change the IP address drop-down type from Dynamic to Manual.
5. 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)
6. For the Gateway, use 192.168.100.1
7. For the Netmask, use 255.255.255.0 - For Connect Spark Pro use netmask of 255.255.0.0
8. Select Apply to save changes.
9. Launch NDI Video Monitor (it would've been installed along with the drivers back in step
