It deos not work
These devices are very reliable and has very little chance this is hardware problem. Please check the following.
1. The serial interface receiver is using the power from the pin 4 and pin 7. Almost all USB/Serial converters do not offer sufficient power to pin 4 and pin7 to power on the receiver. If your receiver is a serial verison and you are using your own USB/Serial converter, you need to plug in 9V to 12V center positive power to the receiver.
2. The correct receiver setup is baud rate 9600, 8 bits data, no parity and 1 stop bit. NO FLOW CONTROL. Please setup these parameters in your serial program correctly.
3. The receiver cannot be too close to the transmitter. For 8 meters transmitter like RF8315T, you need to put those aside with at least 0.5 meters. For 40 meters transmitter like RF40315T ad RF40315T-x, you need to put them aside with at least 1 meter.
4. Has the battery inserted correctly? The +ve should be face up.
