CSS CANedge2 (SD + WIFI)
2 Ch CANBus Data Logger (SD and WIFI)
The plug and play 2 Ch CAN/LIN logger records timestamped CAN data (Classical/CAN FD) to the extractable 8 GB industrial SD Card.
The small device connects via WiFi access points (e.g. WLAN or 3G/4G routers) to securely push data to your server. Further, the device can be updated over the air.
CANedge2 is ideal for telematics, R&D field tests, diagnostics and predictive maintenance.
Pro Specs CSS CAN Logger at half the cost
CSS CANedge2 combines innovative design, cutting-edge components, incredibly low costs:
- 2 x CAN (incl. CAN FD) + 2 x LIN channels
- Extractable 8-32 GB industrial SD card (= months of data)
- Popular binary MDF4 log file format
- Advanced message filtering & transmit functionality
- Route data from CAN1/2, LIN1/2 onto CAN1/2
- Start/stop logging triggers based on CAN ID & databytes
- Silent mode, bit rate auto-detection, cyclic logging
- Data compression & encryption (e.g. for GDPR, CCPA)
- Support for CAN/LIN error frame logging
- Fast boot time. Safely disconnect during use (power safe)

CSS CANedge2 includes an extractable 8-32 GB industrial SD card (Class 10). This ensures e.g. optimal endurance and rapid offline data transfer (W/R 50/80 MB/s) 
CSS CANedge2 enables logging of raw CAN/LIN data incl. CAN FD, J1939, CANopen, OBD2, UDS, ISOBUS, NMEA2000 - across any CAN/LIN application. 
CSS CANedge2 is designed to be extremely compact (75 x 47 x 20 mm). Despite the robust aluminium enclosure, it weighs only 100G. 
2nd port (CH2) provides a configurable 5V power out, letting you easily power e.g. CANmod sensor-to-CAN modules (temperature, analog/digital/pulse, …) 
2x high speed CAN channels enable time-synced recording of data from two CAN buses - ideal for e.g. many heavy duty vehicle applications 
CSS CANedge2 comes with flanges to enable easy installation at scale. The 'mounting kit' includes screws and optional vibration dampeners. 
CSS CANedge2 can upload data via any WiFi router, incl. a 3G/4G WiFi USB router that can e.g. be powered via the 2nd port (see also the CANedge3)
Reinventing Telematics
Fleet telematics is vital across vehicles and machines.
Users face challenges, expensive subscription. No data ownership. Security concerns. Vendor Lock-in.
CSS CANedge2 provides a modern alternative:

- Simply add WiFi access point and server details to the config
- Log data to the SD and auto upload when connected to WiFi
- Configure file split size/period to control upload frequency
- 100% secure, HTTPs, credential encryption and more
- Manage via over the air updates (firmware and configuration)
- Power e.g. a 4G hotspot or GPS to CAN via the 2nd port
- Zero fees. Zero lock in. Interoperable. Open source tools
