Additional Details

The PT2260-R4 typically operates with a supply voltage of 5V. The address and data pins can be configured using DIP switches or jumpers to set the device address and data being transmitted. The encoded data is then modulated and transmitted using an RF or IR transmitter. The 'R4' suffix likely denotes a specific package type or configuration option.
