Secure. License-free.
Built to Last.
35+ years engineering dependable RF and PLC communications that connect remote industrial infrastructure — encrypted, interference-resistant, and free of the recurring costs and vulnerabilities of licensed spectrum.

Build Your Own
Industrial Network.
Design a custom multi-node wireless architecture for your facility. Calculate exact line-of-sight path loss, simulate plant-floor RF clearance with official WiDe math, and send the finished BOM directly to our factory team.

Built around how you work
Whether you're specifying a system or building one, we give you what you need to move forward with confidence.
One vendor, fewer moving parts
One platform covers Ethernet, Modbus, and legacy serial connections across every node in your network, so you're not managing a stack of vendor relationships. One support contact carries the project from design through commissioning.
Request project assistance →Spec with confidence, not guesswork
Free RF-Path studies validate network performance before your design is final, so you're not guessing on link budgets. Datasheets, user guides, and quick-start guides are ready to drop straight into your submittals.
Request an RF-Path study →Fewer support calls, more repeat orders
Built for decades of unattended field life — fewer warranty claims and support tickets eating into your margin. One dedicated regional contact, consistent stock, straightforward reorders, not a rotating cast of reps.
Become a Distributor →Off-the-shelf reliability, or built to your spec
Most of our projects run on our popular SRMs or CIX I/Os proven in the field for decades. When your setup doesn't fit a standard solution, our team works with you to design and build exactly what you need.
