The DNx-SL-514 are high performance SSI (Synchronous Serial Interface) boards for UEI’s “Cube”, RACKtangle and FLATRack I/O chassis respectively. The DNA/DNR/DNF versions are electrically identical and provide four independent RS-422/485 compatible channels, each having over voltage protection and opto-isolation. The 4 channels can be independently configured. Rx/Tx termination resistors may be enabled or disabled via the API.
The board supports standard SSI master or slave functionality as shown in the timing diagram to the right. “tv “, “tp ”, and “tm” are user programmable via the SL-514’s API. Each input word may be timestamped.
Software included with the DNx-SL-514 provides a comprehensive yet easy to use API supporting all popular Windows programming languages as well as programmers using Linux and most real-time operating systems including QNX, RTX, VXworks and more.
