5-11. Programmed Transfer to Local Control (GTL or REN False)
The application program can switch the instrument into Local Control (by sending
Command GTL, or by setting the REN line false), permitting a user to take manual control
from the front panel.
The application program can regain Remote control by sending the overriding command:
Listen Address with REN true (addressing the instrument as a listener with the Remote
Enable management line true {Low}). This will re-impose remote control.
5-12. Device Clear
Either of the commands DCL or SDC will force the following instrument states:
• All IEEE 488 input and output buffers cleared.
• With IFC (Interface Clear), any device-dependent message bus hold-offs cleared.
• The status byte is changed by clearing the MAV bit.
These commands will not:
• Change any settings or stored data within the device except as listed above.
• Interrupt analog output.
• Interrupt or affect any functions of the device not associated with the IEEE 488 system.
5-13. Levels of Reset
Three levels of reset are defined for IEEE 488.2 application programs, a complete system
reset being accomplished by resetting at all three levels, in order, to every device. In other
circumstances they may be used individually or in combination:
• IFC Bus initialization
• DCL Message exchange initialization
• *RST Device initialization
The effects of the *RST command are described in "Device Settings at Power On".
