telos Connii MM 2.0 – I2C Fast Mode Interface for USB 2.0, I2C Multimaster and Monitor
telos Connii MM 2.0 is a small, compact, easy-to-use solution for an USB-driven I2C transmitter and receiver. The I2C interface works as an I2C multi-master device. Thus, it operates on buses with one or more masters installed.
Additionally, Connii MM 2.0 is an I2C Tracer monitoring traffic up to 400 kHz.
Connii MM 2.0 can optionally power the I2C bus with a supply voltage of 1.8 V, 3.3 V or ~5 V (50 mA max.). The power for this is drawn from the USB bus.
The device has two connectors – a standard USB plugin and a PS/2 connector for your I2C bus.
The product comes with the most advanced I2C software package on the market, it is featured by the telos I2C Framework and runs under the sophisticated I2C Studio.
Labview VIs are included running different I2C modes.
All the software is for free, there are no hidden fees!
- 100 kbit/s (Standard Mode) and 400 kbit/s (Fast Mode), theactual rate slighly depends on the I2C bus termination.
- I2C master receiver/transmitter transfers including repeated start 7 and 10 bit addressing
- I2C via Internet
- Extensive software package including interfaces for C++, C#, .NET, Java, Labview, Delphi 8, Python and NXP’s (formerly Philips Semiconductors) URT/URD.
- Superior Windows application I2C Studio
- Usage of several telos I2C interfaces including Tracii XL / Tracii XL 2.0 at the same computer via different USB ports, thus you can drive multiple I2C buses from a single PC!
- Future-proof product: Firmware completely downloaded via USB
- Compact size: The 68*41.5*27.5 mm sized plastic housing protects the device from damages.
- USB powered, no external power supply necessary.
- TCP/IP Network support (I2C via Internet)
- PC connection via USB, supporting both, USB 2.0 high-speed and USB 1.1 full-speed transfers
- I2C connection via Mini-DIN connector
- I2C buses operating at a range of 1.8 – 5.5 Volt can be attached
- ESD protected I2C, IEC compatibility according to EN 61000-4-2 (ESD): Air – 15 kV, Contact – 8 kV
- The I2C Monitor does only recognize regular I2C transfers, no I2C error conditions etc. The monitor stretches SCL, i.e. the SCL line may be held low occasionally. That may lead to problems with master or slave devices that do not support SCL stretching (like some I2C single master implementations).Tracii XL 2.0 offers a more sophisticated I2C Tracer, which includes time stamps for every byte and error recognition.
