6.5V power supply positive.
7.GND power supply negative.
8.ANT connects the antenna terminal.

How it Works:
1. When a key is pressed, the IC is connected to power supply battery and it starts transmitting packets at 315 Mhz frequency consisting of its ID and Data byte which indicates which key was pressed. This information is used in remote control applications.
2. Each transmitter has a pre-programmed unique ID set during manufacturing and cannot change. The receiver board usually stores the transmitter ID in its memory before so the receiver only responds to known transmitter IDs for secure applications.
3. The RF part inside remote is SAW based 315 Mhz transmitter, which can receive by any 315 Mhz type ASK RF Receiver followed by decoder chip.
