OnlywhentheSleeppinsetinthestateofhighlevel(VH<3.5V)orhangs/empty,modulecanbeinreceiving
statusagain.Thedelaytimeforconversionbetween sleepingandreceivingislessthan150mS.
6. Setting of channel, interface, and data format:
User can change or view the module’s parameter setting (interface baud rate and channel) by testing
software “YSPRG.EXE”intheCD(Free).Channel6isdefaultvalue.

Notes:
◢ ModulescanshareDCpowersupplywithotherequipment,Ensurethesupplyisstable(ideally<10mVpk
ripple).
◢ KeepthemoduleawayfromotherEMFgeneratingcomponents.
◢ Match50Ω,1/4waveantenna,highmounttheantennaasclosetothemoduleaspossible.Setantennamore
than2mabovegroundinopenareatoreach optimalrange.
