Connection Details:

Kenwood NEXEDGE Version

The interface enables remote control of Kenwood NEXEDGE radios through a Funktronic Major BOS control panel. It supports serial data communication via RS232 and analog audio transmission.

Motorola MOTOTRBO Version

This version is optimized for controlling Motorola MOTOTRBO radios via USB and RS232. The audio signals are transmitted in an analog way between the Major BOS panel and the radio.

LED Status Indicators:

• Left LED (Yellow): Indicates connection attempt to radio or control panel.
• Right LED (Green): Signals successful connection to Major BOS.
• Blinking LEDs: Shows ongoing communication between radio and control panel.

Programming & Configuration:

The interface allows software-based configuration via the service interface:

• EEPROM settings adjustment.
• Baud rate selection for RS485.
• Potentiometer control for audio signal levels.
