KAVAN Smart PRO SE6 6ch BUS servo decoder - Instruction manual

Introduction

Congratulations on purchasing the KAVAN Smart PRO SE6 4ch BUS servo decoder, a device that converts serial bus signals to standard PWM servo outputs. It offers up to six configurable servo outputs with optional period and fail-safe settings. The SE6 is a perfect choice for models with complex wing or tail mechanics where multiple servos may be connected to a primary receiver using just a single cable. In addition, if you are running out of receiver channels simply connect the SE6 to the receiver serial line and freely assign its own output channels.

Supported protocols:

• Futaba: S.Bus/S.Bus2
• Graupner: SUMD, Hott telemetry for setting
• JETI: EX Bus
• Multiplex: SRXL 12ch, SRXL 16ch
• PowerBox: P²Bus

Features

• Small dimensions and high current throughput via the integrated MR30 power connector

• Automatic detection of serial data/telemetry after startup

• Configuration through the transmitter, external terminal (JETIBOX/SMART-BOX) or MAV Manager PC software

• Firmware updates via USB interface

Installation

Attach the required servos to the SE6 servo expander. Connect the receiver – use its output port with the serial data option. The SE6 uses the MR30 connector for primary data input.

Turn on the transmitter and apply the appropriate power source to the receiver. The status LED starts blinking as soon as the SE6 detects the signal on the serial line.

Telemetry and settings

The device is compatible with JETIBOX for programming. The JETIBOX menu is divided into three sections:

• Actual values - Displays the latest telemetry values (voltage, temperature, system status) together with minimums and maximums.
  • System - Shows the detected serial protocol and its average frame rate.
  • Fadeouts/FS - Number of frame misses and time spent in fail-safe mode. The number of frame misses is increased every time the interval between two consecutive servo frames noticeably exceeds the average period.
  • Reset Min/Max - Press left+right buttons together to reset all minimums and maximums.
• Settings - Basic settings of the sensor.
  • Language - You can choose the language of the JETIBOX screen.
  • Period - You can specify a fixed servo output rate (5ms – 30ms), or automatic output rate synchronous to the serial input.
  • Data Port (6) - Specify a function of the data port – either servo or sensor/terminal can be set.
  • Fail-safe delay - Set the time period that must elapse before entering the fail-safe mode if there is no signal on the serial line.
  • Ch.1–Ch.6 - Here you can set the properties of each output channel. You can modify the receiver channel assignment to the outputs of the SE6. By pressing both left+right buttons you can change the behavior if there is no signal on the serial line:
    • <Hold> (default) - Repeat the last known servo position.
    • <FS XX> - Set the servo position to a fixed value XX%.
  • Set fail-safe now - By pressing both left+right buttons the actual servo positions will be stored as fail-safe values.
• Service - In this menu you can view the device version and reset it to the default factory configuration.
