High anti- interference and Low BER (Bit error Rate) Based on the Gaussian Frequency Shift Keying (GFSK) modulation, the high-efficiency forward error correction channel encoding technology is used to enhance data’s resistance to both transient interference and random interference and the actual bit error rate of 10-5 ~ 10-6 can be achieved when channel bit error rate is 10-2. 4. Long Transmission Distance Within the visible range, when the height of antenna is higher than 2m and The Bit Error Rate (BER) is 10-3, the reliable transmission distances respectively is 3000m @1200bps, and is 2000m@9600bps. 5. Transparent data transmission Transparent data interface used in transceivers is for meeting many standard or nonstandard user protocols. Any false data generated in air can be filtrated automatically (What has been received is exactly what has been transmitted). 6. Multi-channels KYL-300I transceivers offer 8 channels, if needed, 16 or 32 channels are available to satisfy various configuration of communication under user’s demand at the same time. 7. Three connection methods with DB9 connector KYL-300I transceivers provide DB9 connector with three connections: a non-standard RS-232 port and a non-standard RS-485 port. USB interface port is also available, it can get the power for the PC directly. 8.

IV: How to use the KYL-300I KYL-300I provide RS-232, RS-485 and USB interface port for direct connection with PC, RS485 devices, monolithic processors and other UART components kinds of applications. The schematic diagram is shown below: 1. Power supply The factory default setting is +5V(7.5V-12V will inform when placing the order).By using better ripple factor, KYL-300I 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. 2. Connection Definition with terminal KYL-300I transceivers supply one 9-pin connector (JP1), their definitions and connection methods with terminals are shown in Table 1.

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. Supported protocol and Transmit 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. Sleep function instruction: Due to reducing more consumption, KYL-300I transceivers support Sleep function. In sleep mode, the current consumption is less than 20uA. 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-300I, 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.

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 bit received by RxD. Due to a data processing will be made on user’s data by KYL-300I transceiver using FEC (Forward Error Correction) or other correction algorithm, when RxD of a KYL-300I 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: Fax: +86-0755-83408785 [email protected] www.rf-data.com 11 zhen KYL Communication Equipment Co ., Ltd Shen Shenz Co. 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 resent the wrong information while using KYL-300I modules. d. Large-number data transmission In theory, when the interface data rate is faster than the RF data rate, KYL-300I 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). The 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.

Networking Application of KYL-300I The communication channel of KYL-300I is half duplex, which is most suitable for the communication mode of point to multi-point. Under this mode, one master station must be set, and all of the rest are slave stations. A unique address is given to each station. The coordination of communication is controlled by master station that uses data frames containing address code to transmit data or command. Slave station will receive all of the data and command and compare the received address code with local address code. If they are different, the data will be deserted without any response. If those address codes are the same, it means the data is sent to the local. Slave station will make different responses according to the transmitted data or command and send back the data of response. All these jobs must be performed by upper protocol, and it is assured that there is only one transmitter-receiver in the state of transmission in the communication network at any instant moment so as to avoid the cross-interference. KYL-300I can also be used for point-to-point communication with easier operation. For the programming of serial port, all you have to do is to remember that its communication mode is semi duplex while always observing the time sequence of come-and-go for receiving and transmitting.
