Product introduction Yl-900d is a high-performance, low-power, long-distance low-power RF wireless data transceiver, internal automatic spread spectrum calculation and preamble CRC error correction processing, does not change any user's data and protocol, uses half duplex transparent transmission mechanism, realizes the wireless replacement function. The RF chip of radio station is based on spread spectrum frequency hopping technology, which surpasses the existing GFSK radio station in stability, anti-interference ability and receiving sensitivity. With STM low-power and high-speed processor, the data processing ability and operation speed are improved. users can flexibly configure the operating frequency, serial port rate, spread spectrum factor, effective data ratio, spread spectrum bandwidth and other parameters of the radio station through the host computer software configured by our company, which is easy to operate and easy to use. The software and hardware of the radio station are industrial design standards and have strong protection measures. Ensure that it can be stable in special environment

Product overview
Yl-900d is a high-performance, low-power, long-distance micro power RF wireless data transceiver, internal automatic spread spectrum calculation and preamble CRC error correction processing, does not change any user's data and protocol, uses half duplex transparent transmission mechanism to realize wireless replacement function. The RF chip of radio station is based on spread spectrum frequency hopping technology, which surpasses the existing GFSK radio station in stability, anti-interference ability and receiving sensitivity. With STM low-power and high-speed processor, the data processing ability and operation speed are improved. Users can flexibly configure the working frequency, serial port rate, spread spectrum factor, effective data ratio, spread spectrum bandwidth and other parameters of the radio station according to the actual needs through the host computer software configured by our company, which is easy to operate and easy to use. The software and hardware of the radio station are industrial design standards and have strong protection measures. Ensure stable and reliable operation under special environment. There are many kinds of interfaces in the design of the radio station, including industrial grade 485, industrial grade TTL and standard DB9 serial port 232, and 6 ~ 35V wide voltage input. It is a data transmission radio which is fully suitable for industrial application.
