Description
The V_Link01 is an OBD to UART interpreter IC designed to provide bi-directional half-duplex
communication with the vehicle’s On-Board Diagnostic system (OBD-II). It supports all legislated OBD-II protocols, as well as two proprietary networks: for GM Single Wire CAN (for GMLAN), and for Ford Medium Speed CAN (MS CAN).
A wealth of information can be obtained by tapping into the OBD bus, including the status of the malfunction indicator light (MIL), diagnostic trouble codes (DTCs), inspection and maintenance (I/M) information, freeze frames, VIN, hundreds of real-time parameters, and more.The V_ Link01 is fully compatible with the de facto industry standard ELM327 command set. Based on a 32-bit processor core, the V_ Link01 offers more features and better performance than any other ELM327 compatible IC.
Feature
■ Rich instruction set, compatible with more APP software.
-- Fully compatible with ELM's AT command set;
-- Fully compatible with STN's ST command set;
-- Expanded 7 AT commands for HS-CAN, MS-CAN, SW-CAN;
--39 VT macro commands, some instructions are equivalent to the effect of several AT and ST instructions, simplifying the communication steps.
■ Multiple protocols
--15 ELM format protocols;
-- 23 STN format protocols;
-- Up to 64 user-defined protocols.
■ Multiple fieldbus.
-- SAE J1850 VPW
-- SAE J1850 PWM
-- ISO 9141-2
-- ISO 14230-4
-- ISO 15765-4 CAN
-- SAE J1939 CAN
-- ISO 11898 (raw CAN)
-- for GMLAN Single Wire CAN (for GMW3089)
-- for Ford Medium Speed CAN (MS CAN)
■ Multiple power management solutions
-- Compatible with ELM and STN power management solutions.
-- Support for instructions, UART silence, battery low voltage, OBD bus silence, etc. Up to 5 ways to go to sleep;
-- Support UART active, battery voltage drop, OBD bus active, key, etc. Up to 5 ways to wake up from sleep mode.
-- Device sleep power consumption is less than 2 mA.
■ OBD request byte up to 48 bytes, can meet the needs of some special long frame
communication.
■ UART data buffer up to 2K bytes, baudrate increased to 230.4Kbps.
■ User-operated storage area
-- 256-byte storage unit
-- More than 100,000 erasable times
-- Read and write operations on any unit in the storage area by using the VT command
■ " Mix ID Sending" mode of CAN protocol.
-- Optional formatted send data according to protocol
■ Multiple WM sequence settings
-- Support AT command to manually set WM sequence
-- Support for specifying a protocol or a full protocol-wide temporary WM sequence
-- Support for a permanent link between a protocol and a private WM sequence
■ Secure bootloader for easy firmware updates
