Description
The RF Solutions RF600E, & RF600D are easy to use
encoder and decoder I/C’s. They have been designed to
achieve the maximum possible range from any radio / Infra
Red transmitter receiver set.
Unlike other encoder /decoder devices the RF600E/600D
provide an unprecedented level of security which prevents
copying or grabbing whist also obtaining optimum range
from the transmitter and receiver.
The devices are very easy to use and can be inserted
directly into a circuit. The RF600D has an easy learn
feature enabling it to learn up to 7 unique RF600E encoder
devices in standalone mode or up to 48 encoder devices
when used in conjunction with an external EEPROM.
These devices enable a simple but secure remote
telemetry application whilst obtaining the maximum range
from the radio set.

Serial Data Format
Serial Data is sent as a stream of ASCII characters at 9.6K baud. The character format is 8 data bits
with 1 stop bit, no parity.
A serial data string is output every time a valid transmitter packet is received. Due to the nature of
the KeeLoq packet there will be a min gap between each serial data string of 150mSec.
10 characters are sent with the following format;

with battery status
Transmitter serial number
Output from SD1 pin
The Transmitter Serial Number : is made up of 7 ASCII characters from the following group: 0 1 2
3 4 5 6 7 8 9 A B C D E F. The most significant serial number digit is transmitted first. This provides
a total of 28million possible serial numbers.
The KeeLoq Button Status is transmitted as an ASCII character in the range A to O or if the low battery
bit is asserted (encoder battery is low) then in the range a to o. KeeLoq data bits S0, S1, S2 and S3 then
make up the ASCII byte least significant bits D0, D1, D2 and D3.
If a single encoder button is pressed, say S0, then character A will be sent (or if low battery, a).
If encoder button S1 is pressed then B (or b) will be sent.
If S0 and S1 are both pressed simultaneously then character C (or c) will be sent.
If all KeeLoq encoder buttons are simultaneously pressed then character O (or o) will be sent.
Examination of the ASCII bit patterns shows that this allows single or multiple encoder button presses to
be decoded by the ASCII receiving device.
Examples of Serial Data output:
For a three button keyfob with serial number 2345678, the serial data output when encoder transmission
is decoded would be as follows:
If S1 is pressed: 2345678A (2345678a if the battery voltage in the transmitter is low)
If S2 is pressed: 2345678B (2345678b if the battery voltage in the transmitter is low)
If S1 and S2 are pressed together: 2345678C (2345678c if the battery voltage in the transmitter is low)
If S4 is pressed: 2345678H (2345678h if the battery voltage in the transmitter is low)
