UTTISHTA TECH SOLUTIONS: Pro specs CAN bus interface
GENERAL FEATures
Functionality -- CAN-USB/Ethernet interface with 4 x CAN channels (incl. CAN FD)
DISPLAY -- Built-in colorized TFT LCD display (160 x 80 px), Shows CAN channel status
(CAN1-CAN4), bit-rates, errors, busloads, frames/second
Firmware -- Supports free firmware updates for adding features
Software -- Free webCAN app (runs on device) - enter URL shown on device LCD
display to start (zero installation) webCAN lets you configure device,
send/receive CAN frames, DBC decode data, plot CAN signals and more
Free open source Python API for streaming of raw / DBC decoded data
Safety -- CE, FCC, IC, RoHS certified
CAN BUS
Channels --- 4 x CAN FD channels (Controller Area Network)
Standard -- ISO 11898: Compliant with CAN (between 5K and 1 Mbit/s baud rates) and
CAN FD (1M, 2M, 4M, 5M)
Identifiers -- Compliant with CAN specifications 2.0A (11-Bit ID) and 2.0B (29-Bit ID)
Bit Rate -- Bit rates up to 1 Mbps (manually configured or automatically detected)
Bit-rate auto-detection -- Yes
Protocol Support -- Protocol independent (i.e. able to log CAN, J1939, CANopen, OBD2)
Transceiver Protection -- Short-circuit, bus-fault and undervoltage protection
Ideal passive behavior when unpowered (high impedance / no load)
TXD dominant timeout prevents network blocking on transceiver failure
INTERFACES / SECURITY
Interfaces -- Configure device and stream CAN data via USB or Ethernet
USB -- USB is ideal for simple desk setups or e.g. ad hoc in-field
vehicle diagnostics
Ethernet -- Ethernet enables flexible deployments (at scale, remote areas, wireless
via WiFi/LTE routers, ...)
HTTPS (TLS) -- The device uses TLS 1.2 to encrypt all data communication
Discovery -- The CANsub supports mDNS to enable easy discovery of connected
devices on your local network.
DATA STREAMING
Parallel CAN -- Send/receive data from up to 4 x CAN channels simultaneously
Timestamping (RTC) -- The device timestamps data with a 1 µs resolution
Frames/Second -- 20,000+ frames/second across the CAN channels (i.e. in practice any
CAN busload)
Filters -- Multiple regular/extended hardware ID filters per channel
Transmit -- Transmit custom CAN frames - e.g. for OBD2/UDS/XCP/J1939 requests
Transmit sequences can be deployed as 'jobs' on device to enable
embedded CAN frame timing precision
CAN Error Frames -- Support for logging CAN error frames (bit-stuffing, form, CRC,
bit, acknowledgement)
Unique Device ID -- Each device has a globally unique ID
SUPPLY
Input Supply -- +5V via USB connector (optional Power-over-Ethernet adapter available)
Power Consumption -- Extremely low (<1 W)
MECHANICAL
Enclosure -- Robust, small enclosure
Dimensions -- 66.7 x 42.7 x 23.5 mm (L x W x H)
Weight -- 45 grams
Connector -- Standard D-sub 9 (DB9) connector
USB -- Standard mini USB (B) connector for extracting data & streaming
(cable not included)
Temperature -- Operating temperature: -20degC to +65degC
