To access this feature, all you need is a terminal or a computer running terminal emulation software
such as Procomm or Hyperterm for Windows. The diagnostic port is a serial port with the following
connection parameters. Note: A standard 9 pin serial cable is used to connect the terminal device to the diagnostic port, not a null
modem cable. See the diagrams on the following pages for connector locations.
! Baud Rate 19,200
! Data Bits 8
! Parity No
! Stop Bits 1

After connecting to the diagnostics port, power up the controller, type a question mark (?), and press
enter. A menu will appear, displaying the various diagnostic functions available. To select a
function, type the letter shown in the menu and press enter. Some features will prompt for additional
information. To exit a diagnostic function, press the escape key. The display will show a dash line
waiting for another command from the user. Any time a prompt ( >) dash line is shown, a question
–
mark may be entered to display the menu.
