Troubleshooting
Checklist You may want to review the following troubleshooting checklist before contacting
Technical Support.
• Verify that the cabling is correct, see Modem Cables on Page 16.
• Run the bootable diagnostic, see Using the Diagnostics on Page 11.
• Check to see if there is a firmware upgrade available, see Before Installing the
Hardware on Page 2.
• Verify that you are addressing the port correctly. In many applications, device
names above COM9 require the prefix \\.\ to be recognized. For example, to
reference COM20, use \\.\COM20 as the file or port name.
• Check the ftp site to see if there is a more current driver for your operating
system than shipped on the CD (see
Before Installing the Hardware on Page
2).
