Indicator light for receive：indicating receiving data. Ⅴ.How to use KYL-816 1. Transmission mode of KYL-816 1）point to point transmission mode initiatively: The transmission equipment acquires 0-5V voltage analog signal timing, then codes and wireless transmits those. The receiving equipment receives those, codes and outputs the voltage analog signals. That is to say the input voltage from the receiving equipment will be changed with the output voltage from the transmission equipment. The transmitting interval can be set from 10mS to 60S. When it is set as “000”, KYL-816 acquisition module just works as receiving equipment. It will not transmit any data. Otherwise, KYL-816 acquisition module works as transmission equipment which can transmit acquired data according to the transmitting interval you set. The minimum transmitting interval has Fax: +86-755-83408785 www.rf-data.com Shenzhen KYL Communication Equipment Co., Ltd something to do with the transmitting distance. So please specify this when you placing an order. 2）Principal and subordinate acquisition mode. When the receive equipment doesn’t need to show the input voltage from the transmission equipment, just need to transmit the acquired data to a PC or other terminal equipments, you can choose Principal and subordinate mode. The Principal equipment is the PC or other terminal equipments which connecting with a wireless transceiver module (such as KYL-320I). And the subordinate equipments can be acquisition units having address codes with the number of 0-255(the transmitting interval for KYL-816 set as”0”). Under this mode, the wireless transceiver module transmits acquisition command so that the principal equipment can take charge of 255 acquisition modules. 2. Parameters setting Fax: +86-755-83408785 www.rf-data.com Shenzhen KYL Communication Equipment Co., Ltd Picture one ： Software for setting parameter As the above picture shows: Clients can set some parameters by the KYL-80X software, including the below parameters: 1）Module address: from 000 to 255; 2）Channel: total eight channels, each channel have different frequency; 3）Transmitting interval: it will be in effect only when the module is under point to point transmitting mode. The minimum transmitting interval is different subject to baud rate of the module. When it is set as “000”, the module works at the subordinate mode and just takes charge in receiving the output data. Fax: +86-755-83408785 www.rf-data.com Shenzhen KYL Communication Equipment Co., Ltd 3. How to use the software 1）Connect the module to a PC and open the software of KYL-80X, then choose the right port. 2）Electrify, if connect successfully, the software will show “ read success”. Then “read ID”, read success, then you can change the parameter. Note: 1）When you read or set parameter, please fill in the appointed ID first, which is the current module address; also can know the current module address by “read ID”, the “ write ID” command can help you change the current module address. 2）When you set the channel, the maximum channels can’t be changed to eight. Then you should set two modules at the same channel, otherwise they will not communicate. 3）You can also change the parameter by wireless. Connect the wireless data module with PC by UART port (not the UART port of KYL-816), and then you can change the parameter of the KYL-816. 4）Under point to point mode, many double equipments work at the same time, different double equipments should be set different channels.
