5. The Function-indicator light
a. The LED indicator light will glitter red for 0.5S once after switched on.
b. The LED indicator light will glitter green continually while receiving data from air.
c. The LED indicator light will glitter red continuously when transmitting data into air
after receiving from COM.
d. If the module enables the sleep function, LED indicator light is always dark.
6. Supported protocol and Transmit capability
KYL-300H standard transceivers offer transparent protocol to support various
applications and protocols of users. If the user needs to decrease his cost or ease the
workload of terminal CPU, we can add other specific functions based on the transparent
protocol, such as addressing, data acquisition, command interpretation, etc.
7. Sleep function instruction:
Due to reducing more consumption, KYL-300H transceivers support Sleep function. In
sleep mode, the current consumption is less than 1mA.
a. How to use the Sleep function:
The Pin8 ‘SLP’ in JP1 is the signal of sleep control. In high power level, transceiver
stays in working mode. In low power level (<0.5V), transceiver stays in sleep mode.
The SLP signal can convert transceiver from working to sleep mode in 1ms after
falling edge. If the Sleep signal arrives when the transceiver is transmitting data, the
module will enter sleep mode after finishing transmission. From sleep mode to
working, it takes the transceiver 1ms after rising edge.
To disable the opened sleep function of KYL-300H, the SLP (SLEEP) pin should be
definitely connected with 0 or ground.
b. Attentions about use of sleep function:
When the sleep function enabled, any supply glitches, such as switch dithering, fire
striking or quick switching on and off, could cause the transceiver to be switched to
the wrong sleep mode.
After switching on, users can avoid this error by making a compulsive restoration
once after the CPU delays 100ms.
