Description
Inovonics EN4000 EchoStream Universal Serial Receiver | 902–928 MHz RS-232 Wireless Gateway
The Inovonics EN4000 EchoStream® Universal Serial Receiver is a high-capacity wireless gateway that connects Inovonics EchoStream one-way transmitters with a compatible head-end application through an RS-232 serial interface. Designed for security, temperature monitoring, submetering, environmental monitoring, and analog sensing applications, the EN4000 receives EchoStream wireless transmissions, decodes the device data, and delivers formatted messages to the connected application controller.
Operating within the North American 902–928 MHz frequency range, the receiver uses frequency-hopping spread-spectrum technology to support dependable wireless communication in demanding commercial environments. A supervised serial connection helps the host application monitor communication with the receiver, while flexible serial integration can support deployments ranging from hundreds to thousands of wireless devices when paired with an appropriately designed application.
The EN4000 is ideal for organizations and system integrators building scalable Inovonics wireless systems that require a direct serial connection to security software, monitoring platforms, building-management applications, or other compatible head-end systems.
Important Integration Notice: The EN4000 is an RS-232 serial receiver intended for integration with a compatible application controller or head-end software. It is not a standalone alarm control panel, IP gateway, or plug-and-play replacement for every Inovonics panel receiver. Verify the application’s serial protocol, wiring, power, device-support, and programming requirements before ordering.

How the Inovonics EN4000 Works
The EN4000 receives radio-frequency transmissions from compatible EchoStream one-way wireless devices and high-power repeaters. It decodes the incoming information and sends the resulting EchoStream-formatted messages to a connected application controller through its RS-232 serial interface.
The connected software or controller determines how transmitter messages are enrolled, displayed, stored, reported, or acted upon. This architecture allows developers and system integrators to incorporate Inovonics wireless devices into specialized security, environmental monitoring, submetering, data-collection, and facility-management applications.

Compatibility reminder: An EchoStream transmitter being receivable by the EN4000 does not automatically mean that every head-end application can interpret all of its conditions or data. Verify individual transmitter support with the application provider or system integrator.
What to Verify Before Ordering
- Head-end compatibility: Confirm that the application or controller supports the EN4000 and EchoStream serial-message format.
- Connection type: The EN4000 uses an RS-232 serial interface and does not provide a direct Ethernet or Wi-Fi connection.
- Operating frequency: Confirm that the required North American frequency is 902–928 MHz.
- Power source: Provide regulated 10–14 VDC power capable of supplying at least 121 mA.
- Transmitter support: Verify that the head-end application supports the specific Inovonics transmitter models and message conditions being deployed.
- System capacity: Determine device limits through the connected software, controller, database, and overall system architecture.
- RF coverage: Complete an EchoStream site survey and determine whether high-power repeaters are required.
- Cabling requirements: Verify the required serial/power cable, conductor size, cable distance, and connector arrangement.
Installation and RF Planning Guidance
For reliable performance, the EN4000 should be mounted indoors in an accessible location away from metal objects, ductwork, wire mesh, metal enclosures, and other materials that can reduce wireless range. Inovonics recommends using an EchoStream survey kit to evaluate signal strength and determine the best receiver and repeater locations.
- Keep serial cable runs as short as practical to minimize cable capacitance.
- Do not route long serial cables directly beside high-current power wiring.
- Measure voltage at the receiver when long power-cable runs are used.
- Mount the receiver away from large metal objects and enclosed metal housings.
- Keep the receiver accessible for future inspection and maintenance.
- Complete a walk test using each transmitter assigned to the system.
- Verify acceptable signal strength at the receiver from every device location.
- Test the complete system after installation and at regular intervals.
Professional installation recommended: The EN4000 is designed to be installed and maintained by qualified security or systems-integration professionals.
