  • Page 48: Changing Between Local And Remote Operation

    9.4 Changing Between Local and Remote Operation In addition to local mode (front panel operation) and remote, the CL3001 can be placed into a local lockout condition at any time by command of the controller. Combined, the local, remote, and lockout conditions yield four possible operating states as follows.

  • Page 49: Ieee-488 Interface Overview

    To return the CL3001 to the local with lockout state, send the RS-232 LOCAL command or the IEEE-488 GTL (Go To Local) message. Table 4 summarizes the possible operating state transitions. For more information on IEEE-488 GPIB messages, see section 9.5.

  • Page 50: Using Commands

    Refer to section 10 for more detailed information about the commands referenced in this section. All commands, units, and text data may be entered in UPPER or lower case letters. The CL3001 converts all lower case letters to upper case before processing. 9.6.1 Types of Commands The commands for the CL3001 can be grouped into the following categories based on how they function.
  • Page 51 OUT 1 V OPER These could be combined into the compound command: OUT 1 V; OPER These commands instruct the CL3001 to source 1 V DC, and then go into operate mode. Overlapped Commands Commands that begin execution but require slightly more time than the normal communication command/response interval to complete are called overlapped commands.
  • Page 52 IEEE Standards. For example, the command REMOTE could be sent as data over the IEEE- 488 interface to place the CL3001 into remote operating mode, but it is not because the IEEE Standards call for the remote function to be sent to the device as the uniline message REN.
