9 February, 2017 – RAFA Solutions today announced the release of the new versions of SDLC Toolkit for LabVIEW.
Two new versions of the SDLC toolkit were developed recently: with support of NRZ/NRZI data line encoding and with support of embedded clock recovery functionality. Both versions support wide range of data transmission rates from 110 Baud up to 10 MBaud.
SDLC (Synchronous Data Link Control) is a computer communications protocol developed by IBM. SDLC is equivalent to layer 2 of the Open Systems Interconnection (OSI) model of network communication.
SDLC LabVIEW FPGA toolkit is platform independent and supports wide range of National Instruments hardware platforms, such as NI FlexRIO, NI cRIO, NI sbRIO. The toolkit is developed to make integration of the SDLC communication into custom LabVIEW applications easy for developers.
New versions of the toolkit include standard data line encoding/decoding functionality, as well as Non-Return to Zero Inverted (NRZI) encoding, where a logical one is represented by the voltage remaining the same as it was for the previous bit time, and a logical zero is represented by a voltage change.
Embedded clock recovery option of the toolkit allows to communicate with the devices, which do not have separate clock line, but use data to recover the clock internally. The toolkit’s receiver VI recovers the clock from the data line, for the given baud rate.
Drivers can be used to implement single channel as well as multichannel data communication. VIs implement also bit stuffing, unstuffing and CRC calculation on FPGA, which helps users to escape from additional data processing.
