14 on and the lamp is ignited. If you are only configuring the Lambda DG-4 controller or a computer interface, you do not need to switch on the LAMP before turning on the MAIN switch. The following message will be briefly displayed on the front panel when the MAIN switch is turned on: After a few seconds the MAIN MENU will be displayed: At this point, the Controller subsystem is ready for operation. When the unit is first turned on, the FILTER NUMBER display will read “OFF”. This indicates that the filter selecting mirror ...

47 4.1.3 Command Codes All commands to the Lambda DG-4 correspond to an 8-bit binary value (not all of the possible 256 values are utilized). The binary values that are used can be classified in the following way: Table 4-8. Command code types. Value range (Decimal, hexadecimal, binary) Command Type 0 – 15 00 - 0F 00000000 - 00001111 MOVE ON COMMAND to the corresponding FILTER NUMBER (i.e., immediately after receiving the command). 16 - 31 10 - 1F 00010000 - 00011111 MOVE ON TRIGGER to the corresponding FILTER NUMBER (move ...

20 When the ENTER key is then pressed, FILTER NUMBER 8 is then displayed correctly. Method 2: The main menu will look like this if the initial FILTER NUMBER = 10 The numeric key 0 is pressed first. The numeric key 8 is pressed next with no further action required. FILTER NUMBER 8 is then displayed correctly. 3.7.4 Move on Sync Pulse Mode [MODE/4] If the Move on Sync Pulse Mode is active, the controller will advance to the next filter in a previously programmed FILTER NUMBER sequence (Ring Buffer) when an internal video synch ...

24 Figure 3-4. Optical pathway based on filter position. The position of the Output Galvanometer must be coordinated with that of the Input Galvanometer to complete the optical pathway to the Light Guide Port (shown above). The Output Galvanometer angle is also expressed in an arbitrary unit whose value ranges from 0 to 4095. The discrete Output Galvanometer Value that defines the optimal light path for each of the FILTER POSITIONS has been determined at the factory, and can be found on the Optical Alignment Data Sheet. The f ...
