Filter Value Out
This 8-pin, Modular connector provides a digital indicator of the value of the FILTER
NUMBER in use. Pin numbers 1 through 4 correspond to the bit number of the 4-bit binary
equivalent of the decimal FILTER NUMBER value. Pin 5 carries the BUSY line signal and
pins 6 through 8 are tied to ground.

Modes of Operation (LOCAL)
3.7.1
General Information
Filter switch timing can be controlled using one of four different operational modes.
MOVE ON COMMAND (default mode)
MOVE ON STROBE PULSE
The default mode (“MOVE ON COMMAND”) allows you to directly command filter changes
(e.g., using the numeric keys on the keypad when the Lambda DG-4 is under LOCAL
(“Manual”) control). Filter changes can also be controlled using an external trigger (“MOVE
ON STROBE PULSE”), video synchronization pulse (“MOVE ON SYNC PULSE”) or a
combination of these two external sources (“MOVE ON SYNC PULSE, INHIBITED BY THE
STROBE LINE”). By default, the Lambda DG-4 will be in the MOVE ON COMMAND mode
