ROUTe:PATH:DEFine? <path name>

Description

Under the PATH subsystem, this command is used to define or redefine the switch settings that make up a path.

•This command effectively “creates” a path by assigning the path name to one of the 256 internal path registers (if no register is available, a memory error will be declared). No other command referencing that path name may be sent before the DEFine command is sent.

•A path name is any collection of up to 12 uppercase letters (lowercase letters are automatically uppercased), numbers, or underscore characters, starting with a letter.

•If the path name already exists, the old settings (both CLOSE and OPEN) will be erased and the new settings established from the new channel list.

•The channel lists used by PATH:DEF follow all the normal rules for channel lists, and may contain any combination of switches from one or more driver cards. The second channel list is optional; if not sent it will be treated as empty. The empty channel list (@) may be sent for either parameter.

•If a channel is included in both of the channel lists in a path, no error is declared, but the channel will be removed from the first list and only retained in the second.

•The interpretation of the data in a path depends on how it is used. If sent using ROUTE:CLOSE <path name> or by the manual interface, the first channel list is a CLOSE list and the second an OPEN list. If sent using ROUTE:OPEN <path name>, the first channel list is an OPEN list and the second a CLOSE list.
