Po Pow The factory default setting is +5V(3.3-3.6V will inform when placing the order).By using better ripple factor, KYL-500S transceivers can also share power supply with other equipment. If possible, a voltage-stabilizing chip with 5V voltage is more recommended as the only power supply than Switch power supply. But if only switch power supply available, the jam by switch pulse to the transceivers should be avoided. In addition, the reliable grounding must be used if there is other device in the system equipment. In case of failing to connect with the ground, it can form its own grounding but must be absolutely separated from the municipal electric supply. nn ect ion Definition wi 2.

Su Sup rted KYL-500S 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. p fun ct ion instr uct io n: 8. Slee eep unct ction tru ctio ion Due to reducing more consumption, KYL-500S transceivers support Sleep function. In sleep mode, the current consumption is less than 20uA. p f unct io n: a. How to use the Slee eep ctio ion 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-500S, the SLP (SLEEP) pin should be definitely connected with 0 or ground. en ns about use of sl ee p funct io n: b. Att tten enttio ion slee eep ctio ion 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. p Timing Diag Slee eep Diagrram: ntio ns of data tr 9.

Different RF data rate causes different delay time.

Largee-nu num traansmission In theory, when the interface data rate is faster than the RF data rate, KYL-500S transceivers can sent unlimited-long data package, but any long packages more than 120B are not recommended. The length of each package should be between 60~100B. We also recommend user to resent the wrong information using Automatic Error Request Equipment (ARQ). Th Thee analyzing as below: What if the actual transmission BER (Bit Error Rate) is 10-4, 1 packet with 1KB data, which is about 10-thousand bits, is sent, theoretically, at least 1 bit will be received wrongly, then the 1KB information will never be received correctly. But if we package the data into 10 packets with 100B for each, when all 10 packets are sent, there will be only 1 packet wrong according to this probability. After that, resend this wrong packet using ARQ mode. So by resending one more packet and the efficiency rate is reduced 10%, all data will be absolutely received correctly. nn uratio n: 10.
