In the REMOTE MODE only the LOCAL key is active. Holding any other key down while in
the REMOTE MODE may cause an interruption in the reading of new commands from the
remote computer. The functions of the keys are as follows:
0-9 These keys are used to select modes and make numerical entries while in the various
modes of operation. In the MOVE ON COMMAND mode, for example, a FILTER NUMBER
may be selected with these keys.
F1, F2 These key are presently used to manually increase or decrease the Output
Galvanometer Value (see EDIT A FILTER VALUE DEFINITION).
LOCAL Pressing this key puts the unit under LOCAL control. This is the only key that has
an effect when the Lambda DG-4/5 is ON LINE (i.e., under the remote control of an
interfaced external source, such as a computer.
ON LINE This key transfers control of the Lambda DG-4/5 to an interfaced external source,
such as a computer. This transfer can also be done by sending the correct signal from the
external source as outlined under the interfacing section. The default input port is the
PARALLEL PORT, so the display will indicate PARALLEL MODE after the ON LINE key
has been pressed (unless the SERIAL PORT is active).
ENTER This key is used in conjunction with the numeric keys for selecting FILTER
NUMBERS and entering other numeric data. It is also used to exit certain set-up modes
when data entry has been completed.
MODE This key is used to locally to set the mode of operation and to access setup modes.
This key does not directly relate to the mode of input. Pressing the MODE key will initiate a
mode selection routine, which will present a series of linked menus (see the section on
“Selecting an Operational Mode”).
RESET Pressing the RESET button at any time causes the control unit to start the power-
up sequence outlined above. The sequence starts with a delay after the end of the button-
press. The display will be cleared until the initialization screen is written.
3.5 Electrical Connections
All Electrical connections are made on the rear panel of the Lambda DG-4/5.
