Part No.: MPST-STN2120-OBD-II-SW-CAN-MS-CAN-to-UART-Interpreter-IC
STN2120 offers twice as much flash and four times as much RAM, while keeping the same low cost as STN1170.
STN2120 offers the same features and functionality as STN1170 with even higher performance. STN2120 offers twice as much flash and four times as much RAM, while keeping the same low cost as STN1170.
STN2120 is a 44-pin OBD to UART interpreter IC that provides bi-directional, half-duplex communication with all vehicle OBD-II legislated protocols, plus support for SW-CAN (GM) & MS-CAN (Ford). STN2120 is available at the same price as STN1170, yet has twice as much flash and four times as much RAM, allowing for more features to be included with future firmware updates and higher performance.
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:
Control commands commonly found on supported vehicles include:
While STN2120 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.
