Pin Descriptions
Data Lines
The encoder has eight data lines, D0 through D7. The state of these lines
are captured when the SEND line goes high and encoded for transmission.
Upon successful reception, these states are reproduced on the outputs of
the decoder.
SEL_BAUD0 and SEL_BAUD1
These lines are used to select the baud rate of the serial data stream. The
state of the lines allows the selection of one of four possible baud rates, as
shown in Figure 10.

The baud rate must be set before power up. The encoder will not recognize
a change in the baud rate setting after it is on.
GND
These lines are connected to ground.
TX_CNTL
This line goes high when the SEND line goes high, and low when the SEND
line goes low. This can be used to power up an external RF or infrared
transmitter when the encoder is sending data, and power it down when
the encoder is asleep. It can also be used to drive a LED for visual transmit
indication.
DATA_OUT
The encoder will output a serial data stream on this line. This line can
directly interface with all Linx RF transmitter modules.
MODE_IND
This line is activated while the encoder is in Create Mode, allowing the
connection of a LED indicator. The LED will stay on for the entire time the
