Shield for

Arduino

RFD21815

Setup

Reset Button (SW1) : This is tied to the Arduino and will reset the Arduino system

Serial Mode (SW4) Bank 1 : Enables the 5V/3V level translators for the serial

connection between the Wireless shield and the Arduino. This is useful when you want

to put the RX and TX lines in High-Z and electrically disconnect them from the

Arduino.

Serial Mode (SW4) Bank 2 : Sets the RF Mode of the RFD21733. In Mode 2, the

shield will receive data from any RFDP8 Wireless Pipe equipped module. In Mode 3,

the shield will only receive data from any RFDP8 Wireless Pipe equipped modules

which have been “Learned”. See the Network Mode section below.

Learn Button (SW3): This button is used only in Mode 3, when you want to only listen

to particular RFD21733 modules. See the Network Mode section below for more

details.

HW/SW Serial Switch (SW2): This switch allows you to connect the shield to either the

hardware serial pins of the Arduino D0 (Rx) and D1 (Tx) or the software serial pins

which in this case are D10 and D11. Refer to the schematic below for more details.

The RF DIN and RF DOUT led indicators are tied to the RX and TX lines and will blink

when data is sent or received.
