The EN4 is a really nice, 4-port DMX node at a really great price. The added screen allows you to set it up for live events without connecting a computer, which is great as well. From the Manufacturer: The Netron EN4 is a powerful Ethernet to DMX gateway with four RDM compatible ports. Designed for live production and installations with a rugged housing and high-performance processing it offers flexible mounting options to cover any situation. From the GEAR Pro's: The EN4 is hard to beat for the price - a nice, RDM-enabled DMX node that also can be clamp mounted, rack mounted (with the Netron shelf), or DIN rail mounted/wall mounted with the included clamps. It's perfect for live events because it has a screen/knob that allows you to fully set it up without connecting a computer to it. True1 In and Thru's and Network In/Out make it a great rack unit. The Netron software also has a LOT of power under the hood for more complex setups, and if you hook it up to ONYX on the PC, it unlocks "NOVA" mode for (4) universes of free output from ONYX.
