ETS-Lindgren 2090 Controller - Manual (Page 71)

Model 2090 Multi-Device Controller
REMOTE OPERATIONS
The RMT indicator under LOCAL on the front panel of the
controller indicates that the associated device controller is
in remote mode. By default, the controller is in manual
mode unless given a command from a device on the GPIB
bus (usually a computer with a GPIB card installed). When
a command from the GPIB device is given, the RMT
indicator will light and the ADDR indicator will light to
show bus activity. It is not possible to enter remote mode
by pressing the LOCAL key. However, pressing the
LOCAL key while in remote mode will return the Model
2090 to local mode.
While in remote mode, it is possible to change operational
parameters and initiate functions through a series of GPIB
commands. A given command (for example: UP or CW) is
sent from a GPIB device to the Model 2090 controller. The
controller will recognize the address of the device to be
controlled, and execute the required function on that
device.
