Details
STN1170 combines the entire STN1110 (multiprotocol OBD-II) feature set with Single Wire CAN (SW-CAN) and Medium Speed CAN (MS-CAN) protocols in a single 44-pin IC. SW-CAN protocol support allows your device to access, monitor and issue commands on vehicles utilizing GM’s proprietary CAN network. Similarly, MS-CAN provides access to Ford’s proprietary CAN network on supporting models.
On vehicles hosting SW-CAN or MS-CAN networks, our enhanced ST command set allows your device to interpret data not available on the vehicle’s OBD-II bus. Using the GM & Ford proprietary codes, you can commonly interpret current status of systems such as:
- Seat belt
- Airbag
- Headlight
- Anti-Lock Brake (ABS)
- Traction Control
Control commands commonly found on supported vehicles include:
- Door lock/unlock
- Window up/down
- Radio volume up/down
- Turn signals & Hazard on/off
- Engine start/kill
While STN1170 ST commands will provide access to SW-CAN and MS-CAN networks, the proprietary GM & Ford codes must be obtained independently. A popular method is to join the Equipment and Tool Institute where the codes can be accessed/purchased. Alternately, the traffic can be analyzed and reverse engineered.
KEY FEATURES
- Safe, secure bootloader. Reflash the firmware in the field, even over a poor quality link and avoid expensive product recalls.
- Fully compatible with ELM327 command set, ensuring out-of-the-box compatibility with the dozens of existing software applications.
- Extended “ST” command set provides access to enhanced functionality, without compromising compatibility.
- PowerSave mode with multiple sleep and wakeup triggers. Ideal for permanent in-vehicle setups, device can be left connected for extended periods of time without draining the battery.
- Perfect form factor for any application. STN1170 is available in TQFP and QFN packages.
- RoHS compliant
STABILITY
- Solid, field-tested software. STN1170 runs the same proven code that powers the popular STN1110 and OBDLink family of PC-based OBD interfaces. Thanks to its large user base, any problems are discovered and corrected quickly.
- Large OBD message buffer. STN1170 has over five times as much RAM as its nearest competitor, virtually eliminating BUFFER OVERFLOW errors.
- Automatic protocol detection algorithm is continuously fine-tuned to insure that STN1170 will connect to the widest array of vehicles, even those that do not fully conform to the OBD-II standard.
