ETS-Lindgren 2090 Controller - Manual (Page 55)

Model 2090 Multi-Device Controller
OPERATION
MANUAL OPERATIONS
The front panel of the Model 2090 provides the interface
for two separate and complete device controllers, each with
identical displays and function keys. By default, both
controllers are in manual (LOCAL) mode unless given any
command from a device on the GPIB bus (usually a
computer with a GPIB card installed). When in the remote
mode the RMT indicator light will remain on and the
ADDR indicator light will strobe with bus activity.
Pressing the LOCAL key, for Device 1 or 2, will return
only the specific device to local mode. Auxiliary devices
are always available from both the front panel of the Model
2090 and the GPIB interface, regardless of the remote or
local state of the primary devices.
In manual mode, the motion and behavior of the attached
devices can be controlled through the front panel user
interface. The front panel controls allow the user to move
the primary device in between software limits, either
continuously or momentarily in one direction, or to
automatically scan from one limit to the other and back
again. Where supported by the attached hardware, it also
allows the user to change device specific functions like
polarization, speed, and flotation state.
