Figure 2-8. Loop-Back Modes for the MC145572EVK
A: External Hardware IDL Loop-Back on NT1 Side.
Place a jumper between BNC J18 NTRXDATA and BNC J20. Then, from the NT/LT activation menu, select
option I or C. Or, from the command line interface, disable the S/T-Interface Transceiver by setting NR0(b3)
of the MC145574 to a 1. The MC145574 can also be removed from the board.
B: IDL Loop-Back Internal to S/T-Interface Transceiver.
This loop-back may be implemented either from the NT/LT activation menu or directly from the command
line interface. From the NT/LT activation menu, select option B or H. From the command line interface,
enable a 2B+D IDL loop-back in the S/T-Interface Transceiver by setting NR6(b3) of the MC145574 to a 1.
