445 +**Case1**:
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.
448 +
449 +
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.

457 +Enable/Disbale retain Digital Output/Relay Output after power off / Power On
458 +
459 +AT+DOROSAVE=0 ~/~/ Disable Retain after power off/on
460 +
461 +AT+DOROSAVE=1 ~/~/ Enable Retain after power off/on
462 +

466 +
467 +b: for DO2
468 +
469 +c: for RO1
470 +
471 +d: for RO2.
472 +
473 +Example:
474 +
475 +AT+DOROSAVE=2,0,0,0,1 ~/~/ Set DO1/DO2 to Low, RO1 to open after power on , set RO2 to close after power on.
476 +
477 +
478 +=== 2.3.4 Control Sleep status.(Since firmware 1.3) ===
479 +
480 +DI2 can be used to set LT into sleep mode.
481 +
482 +AT+DI2SLEEP=1 ~/~/Enable DI2 as Sleep pin
483 +
484 +AT+DI2SLEEP=0 ~/~/Disable DI2 as Sleep pin
485 +
486 +When DI2 is enabled as sleep pin, a falling trigger (with 500ms pulse) will set LT into sleep mode. A raising trigger will wake up it again.
