RF Transmit Receive Links | |
| These are a series of four kits that implement an RF data link. Each receiver has
a 4-bit address set by an onboard 4-way DIP switch. This allows a total of 16 receivers to
be used in a 'network' with each one being uniquely addressable. The RF modules operate at 433.94MHz and use 'amplitude modulation' to transmit data. This transmission method, also know as 'On-Off Keying (OOK)', transmits data by simply switching the carrier signal on and off. The RF transmitter and receiver modules used in these kits are available as separate items, A18-Tx and A18-Rx. They are produced by 'WenShing' of Taiwan - datasheets can be downloaded from their website at "www.wenshing.com.tw". Each kit contains an Atmel 89C2051 microcontroller that handles all the I/O as well as encoding and decoding the data. The code is NOT available for distribution. |
