Issue Details

Does NI have any SSI interface in its product portfolio? I need to communicate with a device that only uses this protocol.
 

Solution

The way to implement SSI with our products is to use a FPGA board with digital lines and program the protocol in FPGA. With our FlexRIO PXI(e) devices, we provide the NI-6584, which is designed for interfacing with RS422 or RS485. Be sure to use it with a compatible FlexRIO device.

Here you can download a simple example: LV FPGA SSI (Synchronous Serial Interface) Protocol 

In addition, one of our Alliance Members has developed a cRIO module that implements SSI:
