MS Series Encoder Module Data Guide

Unspecified 

The TX_CNTL line is connected to the PDN line of a Linx transmitter so that

the module will enter a low power state when not in use. A LED can also be

connected to the TX_CNTL line to provide visual indication that the encoder

is sending data.

In this example, the data lines are pulled high by simple pushbutton

switches, but many other methods may be employed. Trace contacts,

reed switches or microcontrollers are just some examples of other ways of

pulling the data lines high. The flexibility of the encoder combined with the

associative options of the matching decoder opens a whole new world of

options for creative designers.

System Example

The first step in using the encoder is to set the baud rate using the SPDT

switches. Next, a unique Code Word is created by pressing and holding the

button connected to the CREATE_ADDR line for as long as desired. While

the button is held, the LED will be on indicating that the Code Word is

being created. Once the button is released, the LED will start flashing. The

data buttons that the encoder is to access are now pressed. Pressing the

CREATE_ADDR button again makes the encoder save the new Code Word

and Control Permissions, turn off the LED, and go to sleep.

The decoder must now learn the Code Word for the system to be

operational. Please see the decoder design guide for instructions on

how to do this. The MS Series Master Development System implements

this system, so please see the User’s Guide for the kit for more system

information and circuit schematics.
