Large-number data transmission In theory, when the interface data rate is faster than the RF data rate, KYL-500L 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.
- Page 9 V. Network Application of KYL-500L The communication channel of KYL-500L 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.
- Page 10 KYL-500L 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.
