... E Transmitter Encoder RF803E Functional Description The RF803E is a simple device to use. As shown in the application circuit below, it requires only the addition of input switches and RF circuitry for use as the transmitter in the end application. Transmission is automatic without user intervention. On detecting a switch closure The RF803E will wake up transmit a secure data packet on the TX output ...

... GDN 8 IP3 IP 1-3 These are the switch inputs which when operated wake up the RF803E and cause transmission. They may be switched directly to Ground. Transmission occurs for the duration of the switch operation. Vcc The power supply needs stable regulated voltage between 2.5 and 5.5V with <10mV ripple. ...

... The digital outputs may be configured as latching or momentary action. Latch = the output will change state on each successive transmit of the encoder. Momentary = the output will only operate for as long as the RF803E encoder is transmitting. The RF803D requires only the addition of the following components 1. A ‘Learn’ switch which is used in the process of learning a transmitter/encoder to the decoder and also to initiate erasure of encoder information ...

... DC input. The power supply needs stable regulated voltage with <10mV ripple GND Ground connection. OP1-3 These outputs are asserted LOW when the relevant inputs (S1 – S3) on the RF803E are asserted. (see latch/unlatch information under ‘LKIN’). RX DATA This is the data input to the decoder it may be connected directly to the RF receiver module. ...

... Serial Data Output The RF803D has a serial data output. This outputs the serial number, button and battery status of the transmitter encoder (RF803E). This data may be fed directly to a microcontroller or RS232 type driver circuit which may then be fed directly serial port. Serial data is output initially and again every ½ second whilst data is being received from the RF803E transmitter ...

... Serial Data is sent every 1/2 second as a stream of 7 bytes at 9.6K baud. The serial data format is: 8 data bits with 1 stop bit, no parity. Serial data is output form the Decoder chip whenever a valid data packet from an RF80n or other compatible RF Solutions transmitter is received regardless of learn N Encoder Serial Number [NN]: made up of two 8-bit bytes where the most significant byte is transmitted first ...

... To mark the end of the serial packet ascii characters for carriage return (hex 0D) are sent followed by LF (hex 0A). Custom Versions Custom versions of the RF803E / RF803D chipset are available to provide a bespoke remote chipset for OEM applications. Please contact our sales department for further information. *NOTE: Serial Data output is common across the entire RF80n range, therefore inputs states are sent ...
