NOTE: Generally the module is in receiving status, if the Sleep pin (No.8) continuously connects low level (>200millisecond), the module will be in sleep status, modules can not receive or transmit any data when sleep. 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. Accessories
Standard package: One module+A4# small magnetic car SMA antenna
