With the TSEP LXI Extender, measuring instruments and test systems receive an LXI compliant extension of their functionality, no matter whether in the high-end sector under Windows or Linux, in the middle class sector under Linux with ARM processors or in the low cost sector on own microcontrollers.
TSEP provides an extended LXI Reference Design on a low cost Linux system like Raspberry Pi or Cubieboard. The communication with the existing hardware is done via a standardized interface like I²C (Master/Slave), SPI (Master/Slave), UART and RS232. Extensions for hardware interfaces with higher data rates, such as USB and Ethernet, are possible.
For communication between the customer’s device hardware and the TSEP LXI Extender, a software protocol defined by TSEP is used, which is identical for all hardware interfaces. A reference implementation in C is available for this protocol so that integration into the device firmware is possible without great effort. Not only the data required for the LXI reference design are exchanged via this protocol, but also customer-specific data such as measured values and similar can be exchanged. This data can then be read out or modified by the integrated remote system via the SCPI interface.
