The SCIWIL SW-M808X is an E-Bike Display designed to serve as an ideal Human-Machine Interface (HMI) solution for EN15194 electric bikes. It features a high-brightness, anti-glare color LCD and a minimalist interface, providing essential information and control for the rider.
Function Description:
The SW-M808X display offers a comprehensive set of functions to enhance the e-biking experience. It provides real-time riding status, including Bluetooth connectivity, front light status, brake status, low voltage warnings, turning signals, cruise control, and drive status. The display also shows battery status with a percentage indicator and low voltage warning. A multi-function section allows riders to toggle between various data points such as ODO (total range), TRIP (single ride range), MAX (maximum speed), AVG (average speed), TIME (riding time), VOL (battery voltage), Wh (motor power), and CUR (current). It supports multiple assist level modes (3, 5, or 9 levels available) and a walk assist mode. Additional features include front light indication (status supported by the controller), error code indication, and optional NFC and Bluetooth connectivity for OTA (Over-The-Air) upgrades via mobile phone. For advanced e-bikes, it supports dual drive control and display, as well as the status of double battery packs, both working with a compatible controller. A boot password feature adds security.

Maintenance Features / Safety Notes:
- Installation: The display and keypad are fixed to the handlebar using holder rings/rubber spacers and M4/M3 Hex Wrenches, respectively. Proper torque (1N·m) is crucial to prevent damage.
- Waterproof: The device has an IP65 waterproof rating. Avoid tearing the waterproof film on the screen, as this can degrade its water-tight performance.
- Handling: Avoid clashes or bumps to the display. Do not use in heavy rains, snows, or expose to strong sunlight for prolonged periods.
- Connection: Do not plug or unplug the display while the e-bike is powered on.
- Settings: Unauthorized adjustment to default settings is not suggested, as it may affect the normal use of the e-bike.
- Repair: If the display does not work properly, it should be sent for authorized repair.
- Warranty: Sciwil provides a limited warranty for 24 months after the manufacturing date for quality issues under normal operations. Warranty exclusions include products opened, modified, or repaired without authorization; damage to connectors, surface, wiring/cables; damage due to force majeure or natural disaster; and products out of the warranty period.
- Connectivity: The display connects to the controller via a 5-pin connector. The wire colors and their functions are: Red (VCC) for Display Power, Blue (K) for Electric Lock, Black (GND) for Display Ground, Green (RX) for Display Data Receiving, and Yellow (TX) for Display Data Sending. For extended functions like the front light, Brown (DD) is the power wire (+) and White (GND) is the ground wire (≡). For waterproof connectors, wire sequences may be concealed.
