3/3
Only when the Sleep pin set in the state of high level (V
H
<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.

7. Antenna configuration:
Many appropriative antennas for low power RF modules are selected for meeting different user
antenna configurations. Please ask our Sales office for further information about the antenna’s
dimension and performance. The main options of antennas are exterior flagelliform rubber
antenna with helical SMA joint, magnetic car antenna.
Standard:
A0#
Helical SMA antennas,
L0# 9pin line
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.
