3.5.1 Running the 652X_Demo.hex Program
This object file is the 71M652X embedded application developed by TERIDIAN to exercise all low-level function calls
using a serial interface. Demo Boards ship pre-installed with this program. To run this program:
• Connect a serial cable between the serial port of the Debug Board RS232 and a COM port of a Windows
PC.
• Open a Windows’ Hyperterminal session at 9600 or 300 bps (depending on the setting of jumper
connected to DIO_08 – see the 71M6521 Demo Board User’s Manual), 8N1, one stop bit, with
XON/XOFF flow control enabled. The setup dialog box is shown in Figure 3-1:
• Power on the Demo Board and hit a few times on the PC keyboard until ‘>’ is displayed on the
Hyperterminal screen.
• Type a command from the CLI Reference documented in the 71M6521 Demo Board User’s Manual.
• All references to ‘c’ (lower case c) indicate any ASCII character, all other lowercase letters are one-byte
numbers
• Numbers can be entered in decimal by preceding them with a plus-sign (e.g. hex 20 = +32)
The 71M6521 Demo Board User’s Manual contains instructions on how to connect the serial cable.
