Please find the schematic diagram below: 1. Power supply The factory setting is +5V (needing 3.3V-3.6V, please notify us when placing the order). Using better ripple factor, KYL-210 transceivers can also share power supply with other equipment. If possible, a voltage-stabilizing chip with 5V voltage is much recommended than Switch power supply. But if only switch power supply is available, the jam caused by switch pulse 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.

Setting of channel, interface, and data format Fax: +86-755-83408785 [email protected] www.rf-data.com Remarks Other power supply need customized Choose one of the three interface ports Choose one of the three interface ports zhen KYL Communication Equipment Co ., Ltd Shen Shenz Co. Before using KYL-210, the user needs to make simple configuration to determine the channel, interface mode and data format based on his own needs. You can view or change the module's interface baud rate, channel and address code, parameter setting or reading as per the testing software KYLCOM in the PC (in products box). 5. Installation dimension: 6. The Function-indicator light a. The LED indicator light will turn red for 0.5S once switch on. b. The LED indicator light will turn green continually while receiving data from air. c. The LED indicator light will turn red continually when transmitting data into air after receiving from COM. d. If the module keeps sleep function, LED indicator light is always dark. 7. Supported protocol and Transmit capability KYL-210 standard transceivers offer transparent protocol to support various applications and protocols of users. If you need 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. Sleep function In order to reduce consumption, KYL-210 transceivers support sleep function. In sleep mode, the current consumption is less than 20uA. a. How to use sleep function: The Pin8 ‘SLP’ in JP1 is the signal of sleep control. At high power level, transceiver stays in working mode. At low power level (<0.5V), transceiver stays Fax: +86-755-83408785 [email protected] www.rf-data.com zhen KYL Communication Equipment Co ., Ltd Shen Shenz Co. 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 move to sleep mode after finishing transmission. From sleep moves to working, it takes the transceiver 1ms after rising edge. To disable the opened sleep function of KYL-210, the SLP (SLEEP) pin should be definitely connected with 0 or ground. b. Attentions about using sleep function: When the sleep function enabled, or any supply glitches, such as switch dithering, fire striking or quick switching on and off, may cause the transceiver switch to wrong sleep mode. After switching on, users can avoid this error by making a compulsive restoration once after the CPU delays 100ms. Sleep Timing Diagram: 9. The attentions of data transmission a. The delay time (tc) of conversion between transmitting and receiving is less than 1ms. Timing diagram: b. The delay time of transceivers between the first bit sent by TxD to the first Fax: +86-755-83408785 [email protected] www.rf-data.com zhen KYL Communication Equipment Co ., Ltd Shen Shenz Co. bit received by RxD. As data processing will be made on user’s data by KYL-210 transceiver using FEC (Forward Error Correction) or other correction algorithm, when RxD of a KYL-200L transceiver ‘A’ receives the data, then transmits it, the other one transceiver ‘B’ will have a delay (ts) to receive and transmit by TxD. Different RF data rate causes different delay time. Please see the specific delay time below: RF Date Rate (bps) 1200 Delay Ts(mS) 90 RF Date Rate (bps) 9600 Delay Ts(mS) 16 2400 48 19200 10 4800 30 Timing diagram: c. Error dealing procedure: To enhance the reliability and stability of user’s systems, a verify bit or a Cyclic Redundancy Check (CRC) mode is highly recommended to prevent wrong information while using KYL-210 modules. d. Large-number data transmission In theory, when the interface data rate is faster than the RF data rate, KYL-210 transceivers can sent unlimited-long data package, but long packages more than 120B are not recommended. The length of each package should be between 60~100B. We also recommend our users to use Automatic Error Request Equipment (ARQ) to prevent wrong information. Reasons Reasons:: 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 Fax: +86-755-83408785 [email protected] www.rf-data.com zhen KYL Communication Equipment Co ., Ltd Shen Shenz Co. 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. 10.
