MBOSEPA Interface | Integration for Major BOS & Sepura SRG3900

The MBOSEPA Interface is a specialized unit designed to seamlessly integrate Major BOS control panels with Sepura SRG3900 TETRA radios. It ensures reliable communication by managing audio signals, push-to-talk (PTT) functionality, and squelch control between the Major BOS dispatch system and the Sepura radio.

Key Features:

• Seamless Integration – Connects Major BOS (1a, 2a, 2b, 4a, 8a) control panels with Sepura SRG3900 radios.
• Dual Radio & Panel Support – Supports two control panel connections and two radio device connections.
• Push-to-Talk (PTT) Signal Relay – Passes PTT signals from the Major BOS panel to the Sepura radio.
• Squelch Signal Processing – Extracts and forwards the squelch signal to the Major BOS control panel.
• Configurable Signal Polarity – Jumper-adjustable High Active / Low Active settings for PTT and squelch.
• Audio Level Adjustment – Built-in potentiometers (P1/P3) allow fine-tuning of microphone input levels.
• Fixed Audio Output Support – Requires Sepura SRG3900 radio to be programmed with a fixed NF output level.
• Compact & Lightweight Design – Small form factor for easy installation in radio setups.

Available Versions & SKUs:

• 903060 – MBOSEPA Interface for Major BOS <--> Sepura SRG3900
• 903060.F – MBOSEPA Interface for Major BOS <--> Sepura SRG3900 with Function Key Support
• 903060+ / 903060.F+ – Versions optimized for Major BOS2b (for all other Major BOS models, the standard versions are used)

Programming & Setup:

For optimal operation, the Sepura SRG3900 radio must be programmed with a fixed NF output level using Sepura's PC programming software.

• Ensure correct parameter settings in the "Einrichtung Transceiver-Zubehör" menu.
• Adjust squelch timing and transmission settings for Major BOS compatibility.
• Use the supplied programming cable for setup.
