Pknight Bi-direction ArtNet DMX 2048 Ethernet Lighting Controller - 4

In this review the Pknight Bi-direction ArtNet DMX 2048 Ethernet Lighting Controller is evaluated for live sound and stage lighting professionals who need a compact, truss-mountable node that handles multiple universes. The bottom line: it excels as a reliable network-to-DMX interface with simple local controls and PoE support, making setup and power distribution easier in venues and touring rigs where cable runs and isolation matter. This review focuses on build, setup, and practical use rather than marketing claims.

Key Features

• PowerCON Version: Built-in transformer and PowerCON power input provide a stable power source and allow longer cable runs without voltage drop concerns.
• Four Universe Output: Four DMX512 outputs let the unit control up to 2048 channels from a single compact node, ideal for medium-sized shows.
• PoE Available: Support for 48V Power over Ethernet simplifies installations by letting the device draw power from a PoE switch and avoid a separate power cable.
• All XLR Outputs Opt-Isolated: Two XLR ports include optical isolation to protect the control system and reduce the risk of ground loops and electrical interference.
• Truss Mountable: M10 screw holes on the top panel make it straightforward to secure the unit to truss with a standard clamp or hook for neat stage mounting.
• Easy Local Setup: An LED display and four function buttons allow IP, subnets, and universe settings to be adjusted without a browser, speeding deployment in low-connectivity situations.

Who It's For

The Pknight controller is aimed at lighting technicians, rental houses, and small production companies that need a durable, rack- or truss-mountable ArtNet to DMX node capable of handling multiple universes on a budget. Its PoE option and local controls make it particularly useful for touring rigs and venues that already use managed Ethernet switches.

Less suitable are users who require an exhaustive web UI with advanced routing or profiling tools built into the hardware; those users should consider larger consoles or nodes with more extensive onboard configuration. Also, if more than four physical DMX outputs are required per node, plan on additional nodes or a different topology.

Pros & Cons

Pros

• Compact, truss-ready design that mounts easily and keeps cabling tidy for live shows.
• Supports PoE so power and data can share a single cable when using a compatible switch.
• Optical isolation on XLR outputs improves reliability and protects connected fixtures and controllers.
• Onboard LED display and four-button interface enable quick local configuration without extra software.

Cons

• Configuration beyond IP and universe settings still relies on external software (DMX Workshop) for remote changes, so the unit is not a full-featured controller by itself.
• Only two XLR ports are noted as opt-isolated, which means some outputs may not have the same isolation level.
