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. 7. 7. 7. 7. Supported Supported Supported Supported protocol protocol protocol protocol and and and and Transmit Transmit Transmit Transmit capability capability capability capability KYL-300I 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. 8. 8. 8. 8. Sleep Sleep Sleep Sleep function function function function instruction: instruction: instruction: instruction: Due to reducing more consumption, KYL-300I transceivers support Sleep function. In sleep mode, the current consumption is less than 20uA. a. a. a. a. How How How How to to to to use use use use the the the the Sleep Sleep Sleep Sleep function: function: function: 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-300I, the SLP (SLEEP) pin should be definitely connected with 0 or ground. b. b. b. b. Attentions Attentions Attentions Attentions about about about about use use use use of of of of sleep sleep sleep sleep function: function: function: 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.
