Broadcast Communications

For more than 35 years, Sealevel has developed and manufactured serial communications, digital I/O, and rugged computing products that are trusted by government organizations, broadcast communications companies, commercial customers, and OEMs. We offer over 350 standard products, available in nearly every configuration imaginable. If you need a custom product our award-winning team of engineers can provide a solution that perfectly fits your needs.

Flexible Broadcast Automation Solutions

Broadcast control systems provide a unified and efficient user experience in broadcast communications environments which often includes edge devices, network infrastructure, video routers and switchers, audio routers and mixing consoles, multiviewers, and intercom systems. This complex environment requires seamless communication and interaction between all the various connected devices.

Sealevel is the perfect partner to ensure this seamless connection. For more than 35 years, we have developed and manufactured I/O and rugged computing products that are trusted by broadcast communications leaders, commercial customers, and OEMs.

Robust I/O Solutions

Sealevel offers digital and analog I/O products and data acquisition devices with optically isolated inputs, Reed and Form C relay outputs, TTL interfaces to solid-state relays, and A/D and D/A functionality. Our I/O solutions support configurations from a few inputs to a distributed broadcast control network.

Digital & Analog I/O

Sealevel synchronous and asynchronous serial adapters are trusted anywhere reliable, high-speed communications are required – defense, manufacturing, automation, and broadcast communications. Solutions are available in traditional bus-based form factors or in easy-to-use USB and Ethernet protocols.

Embedded Computing

Designed for I/O-intensive applications, our industrial computers, touch panel PCs and COM Express solutions offer unmatched computing power combined with the flexibility and configurability required for broadcast communications, requiring no fans or
other rotating parts.

Reliable I/O & Ethernet Bolster Broadcast Communications

Case Study

Sealevel partners with a broadcast communications company that dominates the market for producing and distributing sporting events, specifically horse races. Highly reliable, consistent performance of all systems is essential in order to maintain healthy revenue streams that are largely dependent on advertising. To ensure operations, the company uses redundant systems and large backup generators so that their broadcasting capabilities are not impacted by power loss.

They required a device with robust I/O and a 10/100BaseT Ethernet Modbus TCP interface for monitoring and controlling signals from the generator and associated equipment. The system is used for periodic testing and to verify flawless operation.

Radio Transmission Monitoring

Case Study

A leading radio broadcasting company required a reliable, small, cost-effective solution for monitoring and control at transmitter sites. In addition to the dense I/O requirements, the customer requested that the design allow for easy upgrade or replacement of the single-board computer. Sealevel designed a custom Relio system providing a variety of serial, analog, and digital I/O that can be queried or send alerts via the internet or a standard telephone connection.

911 Dispatch Console Computer

Case Study

A leading supplier of communication systems for first responders contacted Sealevel to redesign the 911 dispatch computer used for secure voice to IP communications. An important goal of the new system was to handle the processing and I/O required by their application without the obsolescence issues inherent with their previous “white box” servers and off-the-shelf PCI bus audio cards. The customer also wanted to combine the functionality of an external audio extender product with the main console computer in a single, compact design that could be mounted easily in an equipment rack or under the surface of a desk.

Public Safety Communications

Case Study

Several years ago, a world-leading company in critical two-way wireless communications systems used by public safety and government organizations contracted Sealevel to design an ultra-reliable industrial computer to monitor and control remote broadcast sites nationwide. Sealevel responded with a solid-state system that included all the dense I/O required packaged in a compact 1U, rackmount enclosure. The customer was so satisfied with the operation and quality of over 1,500 units installed to date that they commissioned Sealevel to refresh the design and upgrade to a faster processor and more memory for compatibility with today’s information assurance software, which is required for new installations.
