SCALEXIO Serial Interface Solution

Using Serial Peripheral Interface (SPI) and Inter-Integrated Circuit (I2C) bus

The SCALEXIO Serial Interface Solution lets you connect a SCALEXIO real-time system to an SPI and I2C bus. The solution can be used as decentralized I/O.  

  • Use of Serial Peripheral Interface (SPI)
  • Additional custom I/O function
  • Interface parameterization via software

The SCALEXIO Serial Interface Solution lets you use the Serial Peripheral Interface (SPI) and Inter-Integrated Circuit (I2C) bus with a SCALEXIO system. The solution consists of an I/O solution base board equipped with specific I/O-hardware and software for parameterizing these interfaces with ConfigurationDesk.

The solution can be used with a SCALEXIO rack system, a SCALEXIO LabBox, a SCALEXIO AutoBox or an external I/O unit. The use of an external I/O unit makes it possible to reduce the distance to the device under test, which allows higher frequencies.
