- Page 2 KYL-300H provides 8 channels, expandable for 16, 32 channels according to requirements of users. 7. 2 ports with three connection methods KYL-300H transceivers provide 2 ports with three connections: a UART interface of TTL level, a non-standard RS-232 port and a non-standard RS-485 port. 8. Big data buffer area...
- Page 3 PC, RS485 devices, monolithic processors. The schematic diagram is shown below: Power supply The factory default setting is +12, ±1.2V DC. By using better ripple factor, KYL-300H transceivers can also share power supply with other equipment. If possible, a voltage-stabilizing chip with 12V voltage is much more recommended than Switch power supply.

Setting of channel, interface and data format: Before using KYL-300H, the user needs to make simple configuration based on its own needs to determine the channel, interface mode and data format. The user can change or view the module's interface baud rate, channel and address code.

- Page 7 KYL-300H modules. d. Large-number data transmission In theory, when the interface data rate is faster than the RF data rate, KYL-300H 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 8 IV. Network Application of KYL-300H The communication channel of KYL-300H 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 9 KYL-300H 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.
