RIO-G4

Pharos RIO G4 4-Port DMX Gateway Interface

The Pharos RIO G4 (Remote Gateway 4-Port Device) delivers a scalable, cost-effective way to distribute DMX ports over an Ethernet network. Purpose-built to expand physical DMX output capacity, the RIO G4 seamlessly integrates with Pharos control systems.

Housed in a compact plastic enclosure with easy-to-use installer connectors, DIN-rail mounting, and PoE support, it can be deployed wherever hardware connections are needed. Featuring four fully configurable output ports, the RIO G4 offers a flexible and streamlined data distribution solution that requires minimal configuration.

Installation Instructions

Isolation

Featuring four DMX512 output ports for direct fixture control, the RIO G4 provides independent 2 kV galvanic isolation per port. This shields the main control circuitry and individual output lines from electrical faults, earth potential rise, and ground loop interference.

Power-over-Ethernet

Designed as a Power-over-Ethernet (PoE) endpoint, the RIO G4 can be installed anywhere in your layout using a single network drop to handle both data transmission and system power.

Installer Friendly

Built for permanent hardware setups, it includes 5.08 mm (0.200″) plug-in rising-clamp terminals, a space-saving plastic housing, and seamless DIN-rail mounting. An integrated thumbwheel allows for quick unit addressing and simple activation of onboard DMX test routines.

Protection

equipped with self-healing DMX outputs, the RIO G4 protects connected hardware against wiring mistakes, short circuits, and voltage surges. Once the external error is resolved, the ports automatically reset and resume normal DMX output.

Network Connectivity

Integrates smoothly with any Pharos controller, communicating over standard Ethernet protocols.

Reliable

Solid-state engineering delivers dependable continuous 24/7 operation. Includes a configurable “hold last look” feature that maintains output at a 5 Hz refresh rate if network data transmission is interrupted.

Scalable

Easily scale your setup by pairing multiple remote modules on a single network, tailoring port availability to project needs (overall capacity governed by the host controller).
