### Step 4: Set up the Machine Link

This step discusses configuration of a Serial Link which is the most common. Other links would be Ethernet, HSSB and File.

1. Open a HyperTerminal session on the server computer:

2. From the Start menu, select Programs | Accessories | Communications.

3. Select HyperTerminal.

HyperTerminal is a Windows communication accessory that comes with Windows NT, 2000 and XP. You can use any other similar communication program that can talk with a serial interface.

4. Follow HyperTerminal's initial setup wizard to set the parameters of the serial port to be compatible with the port settings on the NC controller:

For example, COM1, 9600 baud, 8 data bits, 1 stop bit, no parity, hardware flow control.

5. Select a small program on the NC controller.

6. PUNCH out the program to the controller serial port. You should see the program being received in HyperTerminal's window.

7. As an additional test, select Transfer | Capture Text from HyperTerminal. A small dialog box appears.

8. Specify a folder and file name for the captured text file.

9. PUNCH out the program again.

10. Select the Transfer | Capture Text | Stop from HyperTerminal to stop capture.

11. Exit HyperTerminal and open the captured file in a text editor such as Notepad.

12. You should see a copy of the program sent from the NC controller inside the text editor.
