KAVAN SE4 Smart PRO 4ch BUS Servo Decoder
INTRODUCTION
Congratulations on purchasing the KAVAN Smart PRO SE4 4ch BUS servo decoder, a device that converts serial bus signals to standard PWM servo outputs. It offers up to four configurable servo outputs with optional period and fail-safe settings. The SE4 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 SE4 to the receiver serial line and freely assign its 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 4-channel servo/EX Bus sensor expander
Automatic detection of serial data/telemetry after startup
Configuration through the transmitter, an external terminal (JETIBOX/SMART-BOX), or MAV Manager PC software Firmware updates via USB interface.
TECHNICAL SPECIFICATIONS
INSTALLATION
Attach the required servos to the SE4 servo expander. Connect the receiver – use its output port with the serial data option. The SE4 uses the MR30 connector for primary data input. Turn on the transmitter and apply the appropriate power sour
HIGH POWER INSTALLATION
DEVICE MODE: CH1–CH4: EX BU
All extension ports are configured to the EX Bus protocol

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) including 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 increases every time the interval between two consecutive servo frames noticeably exceeds the average period.
- Reset Min/Max – Press the 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.
- Device mode – Specify a function of the extension ports: Ch1–Ch4: Servo – All extension ports are configured as servo outputs.
- Ch4: Sensor EX – Ports 1–3 are configured as servo outputs while port 4 acts as a sensor expander (Duplex EX, EX Bus) or you can connect Hott SMART-BOX for setting in case of SUMD.
- Ch1–Ch4: EX Bus – All extension ports are configured to the EX Bus protocol so that you can simply connect up to four EX Bus-compatible sensors to the device.
- This mode is compatible with the Duplex system.
- Fail-safe Delay – Set the period that must elapse before entering the fail-safe mode if there is no signal on the serial line.
- Ch.1–Ch.4 – Here you can set the properties of each output channel.
- You can modify the receiver channel assignment to the outputs of the SE4. By pressing both the left and right buttons, you can change the behavior if there is no signal on the serial line: (default)
- Repeat the last known servo position.
- Set the servo position to a fixed value of XX %. Set Fail-safe Now – By pressing both the left and 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.
JETIBOX OR SMART BOX CONNECTION
Plug the SE4 into the sensor slot of the JETIBOX/SMART-BOX. Power it up using a battery with appropriate voltage (4.5–8.4V). Now you can configure the device using the arrows on the JETIBOX/SMART-BOX.

SAFETY INFORMATION
- Operate the SE4 always in a dry environment and within the device limits stated in this guide. Never expose the device to excessive heat or cold.
- Do not remove the heat shrink tube from the device and do not try to implement any changes or modifications. This can result in damage to the product and the denial of any warranty claims.
- Always check the polarity of the connection. Never inverse the polarity – this could result in damage to the product.
- Always use a sufficient power source according to the consumption of the attached servos. Never exceed the maximum allowed operating voltage of the attached servos.
- If you use analog servos, please make sure the servo output period is not below 15 ms. Otherwise, the servos may behave unexpectedly.
FIRMWARE UPDATE
Firmware updates for the SE4 are transferred from a PC via the USB interface. The required programs and files are available at www.mavsense.com. (https://www.mavsense.com/).
Install the MAV Manager software and the USB drivers on your computer.
Check the system requirements.
- Disconnect all servos from SE4.
- Connect the USB interface to your PC, run MAV Manager, and select the correct COM Port.
- Connect the SE4 according to the picture below.
- Select the correct *.BIN file and press the Update button.
It is possible to use the MAV Manager software (1.6.0 and later) to conveniently configure all device settings, display real-time telemetry, and make a backup of the configuration. The configuration menu contains four buttons in the top toolbar:
- Refresh – Forces the configuration to be reloaded from the device.
- Import – Imports the settings from a file. If you have several devices and want identical settings, simply import the same settings to each device.
- Export – Exports the settings from the device to a file. You can easily create a backup configuration stored on your PC.
- After creating a backup, you may easily experiment with the settings and later revert to the original configuration by pressing the
- “Import” button and choose the original exported file.
- Reset default – Resets the device to factory defaults and reloads all the settings.
