transmit data to the MCP2150 while the CTS signal is
low. The LCD will indicate that the MCP215X Data
Logger Demo Board is waiting to receive a data byte
from the Primary device.
If SW3 is depressed, the Host Controller will transmit
64 bytes of data to the MCP2150 when the CTS signal
goes low. The LCD will indicate that the MCP215X
Data Logger Demo Board is waiting to receive a data
byte from the Primary device.

Tap on the OK button.
On the PDA:
Tap on the Reset button.
On the PDA:
In the Query window, tap on the Yes button.
On the MCP215X Data Logger Demo Board:
The CD LED will turn on (the IR link is now open) and
the CTS LED will strobe rapidly before returning to the
normal rate.
The second line of the LCD will display the text
“Transmitting” and, once the data table has been sent,
the text will change to “TX Complete”.
After approx. 1 second, the PIC16F877 will return to
the routine used to select how the 250-byte table is
transmitted (see Step 11). The LCD will display the
options.
On the PDA:
Trace will show “250 bytes”.
On the PDA:
This opens the trace buffer window.
The received data table should be in the window.
On the PDA:
This closes the trace buffer window.
On the PDA:
This will open a query window that asks “Reset Trace
Buffer, Are You Sure”.
On the PDA:
This clears the contents of the trace buffer. Trace
shows “0 Bytes”.
