Description
Features
- All-in-One 4×4 RDM-DMX512 Signal Splitter：Integrates four sets of 4-way bidirectional RDM-DMX512 signal distributors into one unit—replacing up to four separate splitters. Ideal for complex lighting systems requiring long-range transmission and multiple fixture branches.
- True Bi-Directional RDM Communication with Switch Control：Fully supports the RDM (Remote Device Management) protocol for two-way communication with RDM-enabled devices. Easily enable or disable RDM functionality using the onboard RDM switch to prevent protocol conflicts when not needed.
- Isolation Built In, Protection All Around：Each channel operates with complete electrical separation through optical isolation and independent power. This eliminates ground loops, blocks voltage surges, and shields your lighting console and fixtures from electrical interference.All signal ports are fitted with genuine Neutrik XLR connectors to ensure secure locking, low contact resistance, and long-lasting reliability.
- Designed for Clean, Reliable Signal Delivery：Termination resistors and surge absorption circuits are integrated directly into every output. Signal reflections, external noise, and long-distance degradation are all minimized for a stable and professional-grade DMX/RDM network.
- Real-Time Monitoring with High-Visibility LED Indicators：Each output port includes a high-brightness blue LED to indicate live signal status. Provides instant visual feedback for quick diagnostics, system setup, and live performance assurance.
- Wide Compatibility with DMX Lighting Systems：Works seamlessly with DMX512 and RDM-enabled lighting consoles, dimmers, LED fixtures, and controllers. Perfect for stage lighting, architectural installations, clubs, churches, and entertainment venues.Compatible with standard 3-pin DMX cables and professional Neutrik XLR connectors for rugged stage use.
- Durable Metal Housing and Rack-Mount Ready Design：Built with a rugged metal chassis for long-term reliability and noise shielding. Standard 1U rack-mountable format ensures quick and secure installation in touring cases or control room setups.
Product Description
Overview
The Pknight RDM1602 is a professional-grade 4-in-1 RDM/DMX512 signal splitter designed for demanding lighting control environments. Engineered to meet the needs of stage, architectural, and touring installations, this advanced device integrates four fully independent 1-in 4-out signal distribution zones into a single 1U rack-mountable unit—replacing up to four traditional splitters. Each zone features photoelectric isolation, individual surge protection, an RDM on/off switch, and selectable termination, ensuring clean, safe, and reliable signal distribution across your lighting network. With support for full bi-directional RDM communication, users can remotely monitor, configure, and troubleshoot connected fixtures with ease. Whether you’re managing a large-scale stage production, a multi-room lighting setup, or a complex fixed installation, the RDM1602 offers unmatched flexibility, safety, and efficiency—all in one compact, easy-to-deploy solution.

Q&A
-
Q1: Is this device compatible with both DMX512 and RDM protocols?
A1: Yes. The RDM1602 fully supports standard DMX512 and RDM (Remote Device Management) protocols. You can use it with DMX-only or RDM-compatible lighting fixtures.
-
Q2: Can I disable the RDM function if I don’t need it?
A2: Absolutely. Each of the four zones is equipped with a physical RDM switch. You can turn RDM on or off per group to avoid signal conflicts with non-RDM devices.
-
Q3: How many fixtures can I connect to each output?
A3: Each isolated output supports up to 32 DMX fixtures, according to the DMX512 standard. With 4 groups and 16 outputs total, you can control a large number of fixtures efficiently.
-
Q4: Is the signal electrically isolated between groups?
A4: Yes. All inputs and outputs are optically isolated and powered independently. This design prevents signal interference and protects your lighting console and fixtures from electrical surges.
-
Q5: Can I mount this unit in a standard 19” rack?
A5: Yes. The RDM1602 is housed in a durable 1U rack-mountable metal chassis, ready for touring cases, control rooms, or permanent installations.
