Who each one is for
The Adder Technology Adder ALIF1002P suits enterprise IP KVM matrix deployments centered on DVI video and facilities already using Adder's ADDERLink Infinity Manager, though it is the wrong buy for multi-monitor workstations needing dual-head DVI, where the ALIF2112T fits better and HDMI or DisplayPort-based workstations. It also earns its place with buyers wanting a complete matched transmitter/receiver pair rather than individual nodes. It is not the one for small single-room extension budgets, where the Emerald EMD2000PE-T costs roughly half as much. The J-Tech Digital JTECH-DKM21-8K is the one to take for Dual-PC desks sharing one high-refresh or high-resolution monitor and users who want DisplayPort 1.4 bandwidth for 4K@240Hz or 8K@60Hz, though it is not the pick for setups with more than 2 source computers and HDMI-only computers or monitors (DisplayPort only). Our rating of the Adder Technology Adder ALIF1002P (7/10): A capable enterprise DVI network extender pair, priced for serious IP KVM matrix deployments rather than single-room extension.
