Digital Link with CRC Processing in the LT and NT1 (Option 3)
In this mode, the NT1 behaves like in option 2. The LT is not transparent, but has
CRC4 generation and monitoring in both directions. This option is not possible
when using combined NT1 & LT mode, the set-up for option 3 is:
• The master is PRA LT with CRC4 processing on; the slave is PRA NT1 with
CRC4 processing on.
