Chapter 1: Overview Along with the J4 standalone units, there are also J4DPe and J4HDMIe boards which may be inserted in the Catalyst XL or Catalyst V to provide the same functionality as the J4DP and J4HDMI. Figure 1.2: Architecture of J4 with Catalyst Small and powerful, the J4 video wall processor can be combined with 4K outputs from Jupiter processors to create a large video wall with up to 64 FHD displays.

2.1.4 Multiple Subnet Support J4 devices which are in the same subnet are detected through the UPnP (Universal Plug and Play) protocol. If your devices are in different network subnets, you need to validate network discovery in each subnet separately.
J4 Configuration Software simplifies video wall designs and Installations of J4 multi-monitor controllers. The Software works in offline mode to customize configurations of any type and size. Configurations are then uploaded to your physical devices. J4 configuration software enables you to set up your devices in three steps- create, discover and deploy.
