446 -
447 -AT+DI1TODO1=1 ~/~/ LT2 DO1 will follow LT1 DI1 trigger command, if DI1 of LT1 is trigger high, DO1 of LT2 will output low, if DI1 of LT1 is trigger low, DO2 of LT2 will output high.

450 -**Case2**:
451 -
452 -AT+DI1TODO1=1,60 ~/~/ LT2 DO1 will follow LT1 DI1 trigger command, DO1 will keep the status 60 seconds and then go back to original state.
