Secure Wireless
Relay Control
Industrial wireless control system enabling secure, authenticated switching of solid-state relays over Sub-GHz radio links with ECDH encryption and AES-CMAC authentication.
Industrial-Grade Features
Built for critical applications requiring secure, reliable wireless control.
Sub-GHz LoRa Radio
Long-range communication in the 915 MHz ISM band. Better penetration and range than 2.4 GHz alternatives.
ECDH + AES-CMAC
Hardware-accelerated P-256 key exchange. Every packet authenticated with truncated CMAC tags.
PLL-Synchronized TDMA
Software phase-locked loop for precise timing synchronization. Adaptive beacon intervals based on link state.
Opto-Isolated Channels
Two opto-isolated "dry contact" channels per unit. Can be used as switch inputs or controlled outputs.
PinSync Wireless I/O
Three bidirectional I/O lines for wireless level shifting. Board V4 exclusive feature.
VISA/SCPI Ready
Desktop service with REST API, WebSocket telemetry, and native NI-MAX/LabVIEW integration.
Built for Industrial
Reliability
Every parameter derived from firmware documentation and verified against source code. No invented specifications.

Industrial-Grade Security
Unpaired devices cannot control SSR outputs. Every packet is cryptographically authenticated.
ECDH Key Exchange
One-time pairing using P-256 curve. Public keys exchanged over 11 radio packets, shared secret stored in flash.
Session Establishment
Previously paired devices reconnect with SESSION_START/CONFIRM handshake. Session key derived per connection.
Per-Packet Authentication
Every operational packet includes 4-byte truncated CMAC. 8-bit sequence numbers prevent replay attacks.

Built for Your Use Case
From button-initiated control to automated test systems, WiEPOut T1 adapts to your workflow.
Wireless Relay Control
User presses button on TX unit to toggle SSR outputs on RX unit. CMAC-authenticated commands with confirmed ACK responses.
Host-Controlled Operation
Host PC sends UART commands to TX unit, which relays them wirelessly to RX. REST API, WebSocket, and VISA/SCPI interfaces available.
Wireless I/O Sync
Toggle switch changes synchronize wirelessly between TX and RX units. Functions as a "wireless level shifter" for discrete I/O.
