Checking the Connections
Setting Up
Sometimes problems are caused by unconnected cables. Turn off the
programmer and check the following:
� Power cords—Are all power cords plugged into a live outlet and into the
equipment?
� Cables—Is each cable between the programmer and a peripheral correctly
connected to the proper port?
� Terminal—Is the terminal plugged in and turned on? Are the display
controls adjusted to allow viewing? Is the terminal an approved terminal
type? (See the list on page 2-6.)
� Communication—Are the communication parameters set correctly? Is the
cable connected to the proper port?
� Host—Is the host plugged in and turned on? Is the terminal emulation
software installed, configured, and running properly? Are the display
controls on the monitor adjusted to allow viewing?
� Disk—Is the Boot disk inserted properly?
� Base—Is a Base installed correctly? Is the device socket empty? (A base
must be installed and the socket must be empty.)
After you check everything described above, reboot the programmer using one
of these methods (a powerup self-test is performed in either case):
� Turn off the programmer, wait a few seconds, then it on turn again.
� Press ESC CTRL+W.
If the Start-up screen (shown in Figure 2-8) is displayed, the programmer was
booted successfully. Continue with “Start-up Screen” on page 2-18.
If the Start-up screen is not displayed or if you see random characters, the
programmer is not communicating properly with your controlling terminal/
workstation. The baud rates of the programmer and the controlling equipment
may not match. Follow the procedure in the next section to run the AutoBaud
function to “sync up” the baud rates.
AutoBaud and Baud Rates
AutoBaud determines the baud rate of the equipment connected to the
programmer's Terminal port and sets the programmer's baud rate to match.
Note: AutoBaud is enabled as a factory default.
To run AutoBaud, press BREAK, then A. After running AutoBaud, you should see
the Start-up screen. If so, go to the next step, “Start-up Screen.”
If you do not see the Start-up screen, return to “Checking the Connections.”
When to Use AutoBaud?
Normally, you can set the communication parameters on the controlling PC/
workstation/terminal to match the programmer's baud rate. Use AutoBaud
when you will not be able to set the controlling equipment's baud rate to
match the programmer's.
For example, use AutoBaud to control the programmer with a terminal that
cannot operate at 9600 baud. Set the terminal's baud rate as close to 9600 as
possible, then run AutoBaud when the programmer boots up.
