8.Select Diagnostics Check Operating System Version (alternatively, depress F5) from the Viewport. The Viewport may display a window as it scans various baud rates. Eventually, a message should appear in the Incoming section showing a version number. Such a response indicates that communications have been established.

If a “No Communications with Rack” error message opens, proceed to “Troubleshooting Communications” on page 10. If the baud rate of the CEN-CN was something other than 38400, the software automatically adjusts the baud rate to 38400.

Troubleshooting Communications

If communications with the CEN-CN has not been established, follow the steps in this section to help remedy the problem.

1.Verify that the cable being used is correct. (If cable is not available, refer to “Configuration Cable Fabrication Specifications” on page 7.)

2.Verify that the proper COM port on the PC has been selected. Some PCs have more than one COM port, some of which may be internal (e.g., for a modem). If verification can not be made, consult the PC user’s manual or contact the manufacturer.
