jumpers in a predetermined pattern and powering
up the unit. The S_in pin must be grounded at
power-up to enter test mode. When the RXS jumper
pin is grounded and the STBY jumper pins are clear,
the PW1-928 node is placed in transmit test mode.
Conversely, when the RXS jumper pins are clear
and the STBY jumper pins are grounded, the PW1-
928 node assumes the receive test mode. The
transmitting node sends an ASCII message every
330 ms. I set up one of the PW1-928s as a
transmitter and the other as the receiver. The results
can be seen in Screenshot 3.
Now that you have an idea of what the PW1-
928 RF data transceiver module can do, get a dev
kit and put it through its paces.
Odds are, if your application requires a small,
easy to deploy, low current consumption, long
range data radio, the Patriot PW1-928 will find its way into
your Design Cycle. NV

■ SCREENSHOT 3. After switching the terminal emulator baud
rate to 9600 bps, I jumpered-up a pair of PW1-928 nodes as
transmitter and receiver. What you see here is the data gleaned
from the receiver.
