Tech Tip: Translating PAC Control Error Codes

If you get an error in PAC Control and only the error code number appears, how do you know what it means? Here are some easy ways to find out.

Use Error Lookup

In PAC Control Basic and Pro versions 9.0 and newer, click the Help menu and choose Error Lookup. Enter the number of the error (including the minus sign) and click Get Error:

Error Lookup dialog box in PAC Control


Use PAC Control help

In PAC Control, click the Help menu and choose Command Reference. When the Help opens, you have a couple of options:

If you know the command that produced the error, click the Index tab and start typing in the name of the command. Find it in the list and double-click it. Then scroll down till you see the Status Codes section. The common error messages are listed and defined with reference to that specific command.

If you don't know the command, click the Search tab and search on "errors" (or "error codes" or "error messages"). In the list of results, double-click List of Common Messages. Errors are listed in numeric order; scroll down to see the one you want:

List of common error messages in PAC Control Help


RTFM (Read the fantastic manual)

If you still like paper (or a PDF), you'll find the most common error codes listed for each command in the PAC Control Command Reference, form 1701. Just look up the command name in the index at the back of the book, or search in the pdf for the command name.

Or, for the complete list of common error messages, see Appendix B in the PAC Control User's Guide, form 1700.
