Initial Setup

Unpack the development system, attach the antennas and install a 9V

battery on each development board. The boards can be used in two

different configurations: Prototype and Evaluation. The Mode Selection

switch sets the configuration. By default, the boards are set to Range Test

in the Evaluation configuration.

Evaluation Configuration

Setting the Mode Select switch to the EVALUATION (right) position enables

the Evaluation Configuration. In this configuration, the module’s signal lines

are routed to the Evaluation Area for control. This enables the module to be

configured by the controls on the board while allowing custom data to be

sent over the link.

Range Test

The development boards feature an onboard Linx MT Series transcoder

which facilitates range testing. Buttons on one board activate a light or

buzzer on the other. A confirmation LED provides visual acknowledgment

that a transmission was received across the wireless link.

Range Test is part of the Evaluation configuration and is the default

configuration out of the box. To use the boards this way, place the Mode

Select switch to Evaluation and the Evaluation Select switch to the RANGE

TEST (middle) position. This routes the DATA_IN, DATA_OUT and T/R_SEL

lines to the MT Series Transcoder.

Prototype Configuration

Setting the Mode Select switch to the PROTOTYPE (left) position enables

the Prototype Configuration. In the Prototype configuration, the module’s

signal lines are routed to the break-out header next to the Prototype Area.

This allows the module to be controlled with custom application circuitry.

Software Development

The kit includes one USB interface board for connection to a PC. Included

software demonstrates use of the module’s Command Data Interface (CDI).

Troubleshooting

If the boards fail to work out of the box, then try the following:

• Make sure that the Master Power, Mode Select and Evaluation Select

switches are in the correct positions. The Active LED should be on
