8.7 Interface Board Features
The locations of the LEDs on the interface board that are used by the DNT24 are shown in Figure 8.8.1.
Figure 8.8.1
DCD LED, D11, illuminates on a router or remote to indicate it is registered with its parent and can partic-
ipate in RF communications. The DCD LED illuminates on the base when one or more routers or
remotes are registered to it, unless the base has been configured to assert DCD on power up. In this
case it will be on as long as the development board is powered. Activity LED, D10, illuminates when
transmitting or receiving RF data. Power LED, D1, illuminates with the DNT24 and its interface board are
powered. GPIO2 LED, D5, and GPIO3 LED, D4, can be controlled by configuring GPIO2 and GPIO3 as
outputs on the DNT24. These LEDs are illuminated with a logic high signal.

Figure 8.8.2 shows the connectors and switches to the right of the DNT24P mounting socket. JP3 and
JP4 normally have shorting plugs installed as shown in Figure 8.8.2. JP3 connects ADC0 to the yellow
potentiometer. Clockwise rotation of the potentiometer increases the voltage. JP4 connects ADC1 to a
thermistor temperature sensor. The DNT24 has its own boot loader utility that allows the protocol firm-
