Ssi encoder with special bits

Hello I have a P+F AHM58 ssi encoder with spcial bits, the signal information like the pic. i want to know this ssi encoder data can be readed by rmc?
i want to use a u14 module to receive then data of then encoder

i see " SSI Low Bits to Ignore" and " SSI High Bits to Ignore" in helps .
Maybe it is the key to read data from encoder with special bit

Correct, the SSI Low/High Bits to Ignore feature was designed for this purpose.
