Page 5: Introduction
Figure 1: Package Dimensions Introduction The HS Series encoders and decoders are ideal for remote control and command, security, keyless entry, status monitoring, and a host of similar applications. They encode the status of up to eight buttons or contacts into a highly secure serial output intended for transmission via an RF or infrared link. -
Page 6: Ordering Information
The Master Development System includes 2 development boards, one set up for the encoder and the other for the decoder, 2 HS Series encoders*, 2 HS Series decoders*, and two CW Series antennas. The boards may be populated with either the LR Series or the ES Series RF modules. The decoder board is also populated with 1 QS Series USB module. -

Page 8: Using The Development Boards
Using the Development Boards After unpacking the development system, attach an antenna to each board, install the supplied 9V battery, and turn on the power switches. The encoder and decoder will be set at the factory and will work straight out of the box. -
Page 9: The Prototyping Area
• Make sure that you set your Control Permissions correctly. If you have not set the encoder to use a particular line, then when you press a button on the encoder board, the MODE_IND LED on the decoder board will light up, but the data line LED will not light up. If all of these appear to be in order, then you can call +1 800 736 6677 or email techsupport@linxtechnologies.com for technical support. -
Page 10: The Power Supply
The Power Supply The power supply is the same on both boards and consists of a standard 9V battery and a power jack connected to a 3.0V voltage regulator. The regulator can provide approximately 500mA of current to the prototyping area. - Page 11 TX Control Mode of the encoder can be tested. This mode is described in the HS Series Encoder Data Guide. If a BSEL switch is up, then the line is high (1, V );...

The Encoder Board RF Area Figure 8 shows the RF area of the development board. Figure 8: Baud Rate Selection Table This board can be populated with either the LR Series transmitter (as shown) or the ES Series transmitter. The LR Series transmitter will be placed on the right side and the ANT1 connector will be populated. - Page 13 9.1M 9.1M 100k 5.1M To KEY_IN 9.1M 4.7uF 9.1M 0.01uF Figure 10: The Infrared Receiver Circuit The left side of the circuit consists of an op-amp that is set up as a timer to feed current into the phototransistor for a specific amount of time after the button is pressed.

Page 14: The Decoder Board
LED D0 corresponds to data line D0 and so forth. Beneath the decoder is an LED that is connected to the MODE_IND line. This will light up as described in the HS Series Decoder Data Guide. Beneath the LED are three buttons. The one on the left labeled HS_SEND_ KEY is connected to the SEND_COPY line on the decoder. -

Note: The encoder board must be set to the same baud rate in order for the signal to be received correctly. The maximum baud rate for the LR Series is 10,000bps, so only 2,400 and 9,600bps can be used on boards populated with these modules. - Page 16 The Decoder Board USB Area The development boards have a Linx SDM-USB-QS-S module for use with the included development software. This module is powered by the USB bus so will not pull any current from the battery. Figure 13 shows this section.

Page 17: The Decoder Board Key Exchange Area
The Decoder Board Key Exchange Area Figure 14 below shows the key exchange area of the development board. Figure 14: The Decoder Board Key Exchange Area The KEY_IN jack and the IR receiver circuit are identical to the encoder board. Since the decoder must also send a key to an encoder and / or another decoder, the KEY_OUT jack is populated. - Page 18 When a data line goes high on the decoder, the microcontroller will send a command to the computer to control the functions in the software. Please see the documentation included with the software for details. Figure 15: The HS Series Master Development Software – –...

Page 19: Installing The Software Drivers
View Documentation button will show a list of the application notes and manuals related to the HS Series. Selecting one of these will open the file in Adobe Acrobat. The Play Movie button will play a short video about Linx on the Player Screen, which can be controlled with the Selection Keypad. - Page 20 option of installing Flash, which may be required if the Linx video does not play correctly. The Read Me file found in the View Documentation list will have extra information on the software that may not be in the software documentation, so it is a good idea to read this file before using the software.
