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. 5. 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).6.
