Price cut for Connii
Connii is our budgetary solution for a compact and easy-to-use I2C to PC interface. Being a plug-and-play product, Connii is an ideal device for simple I2C master operation.
Connii is now available for only 250 Euro instead of 290 Euro.
We would like to point out that Connii only supports slave devices which do not stretch the I2C clock. In case you have a stretching I2C bus, you want Connii MM which includes a basic I2C tracer as well.
New Feature: IRD
Starting with I2C Studio release 2.0 it is possible to use an entirely new level of I2C device access.
Instead of working with addresses, offsets and byte values the user is provided with a comprehensive view of device registers which are given by the names used in the data sheets.
Mapping between such names and the physical locations within a device are ... read more >>>

DIN Connectors / Probes
In response to many customer requests we have included a mini-din probe in our product catalogue. With this adapter, Tracii XL, Connii and Connii MM can be easily connected to targets without soldering. Please see our online shop facility for more information on this product.
Tracii 400 gets dressed!
Starting 2006 Tracii 400, our parallel port to I2C interface now comes in a solid plastic housing. A transparent area exposes the LED and there are openings for all connectors.
Tracii 400 will be available for 855 Euro. Maybe you should consider placing your order in 2005 to benefit from the old price.
Tipps and Tricks
No bandwith problems
It is possible and recommended to connect multiple telos I2C devices to one PC and use them concurrently within I2C Studio or through the API.
If you had only one USB bus in your system, all connected devices would share the bandwith of the bus. However, all modern PCs have multiple USB buses where each of them provides its own independent 12 megabit bandwidth for USB 1.1 compatible devices.
We therefore suggest to connect each telos I2C device to a different USB bus, especially if you are tracing.
If you open the control panel and click System, you can select each USB hub in the device manager (under the hardware tab) and click on "power" to view which device is connected to which USB bus.
