Page 7: Section 2 Setup
NSI DS8/DS12 MODULAR DIGITAL DIMMING SYSTEM _______________ __________ Section 2 SETUP The DS dimmer pack will be ship pre-configured with factory default settings, however, it may be necessary to change some of those settings in the field based on installation requirements or service conditions. The following section steps through the various control setup options. - Page 8 NSI DS8/DS12 MODULAR DIGITAL DIMMING SYSTEM 2.3 Test Switch Action / Level Selection: From the main menu: NSI DSxx xPHASE STATUS=xxx [MORE] Press the key sequence [MORE], [MORE], [SETUP], [MORE] [MORE]. The following menu will be displayed: SET TEST SWITCH [ACTION] [MORE] Select [ACTION].
- Page 9 NSI DS8/DS12 MODULAR DIGITAL DIMMING SYSTEM 2.5 Factory Defaults Selection: There are an abundance of functions that are initialized if this selection is made: All non-analog presets in memory ( Presets 13 through 400 ) are completely erased. Both DMX-512 and Microplex softpatches default to 1:1 at full on channels 1 through 12.
- Page 10 NSI DS8/DS12 MODULAR DIGITAL DIMMING SYSTEM 2.7 Set Line Regulation This menu enables or disables the line regulation feature of the dimmer pack. Line regulation is a feedback system that monitors the incoming line voltage, and attempts to compensate for surges or sags in the feeder voltage by inversely dimming the output up or down, thereby maintaining a constant output voltage to the lamp.
- Page 11 NSI DS8/DS12 MODULAR DIGITAL DIMMING SYSTEM _________________________________ Section 3 SOFTPATCH The DS dimmer pack has the ability to be patched quickly if only a start address is required and normal full range dimming is required, or it is capable in the custom patch menu of proportionally patching any DMX-512 or Microplex multiplexed control signal to any dimmer, setting custom dimming curves, and setting maximum and minimum control levels.
- Page 12 NSI DS8/DS12 MODULAR DIGITAL DIMMING SYSTEM 3.3 Custom Softpatch Please note that all softpatch entries are stored in non-volatile EEPROM, and are automatically loaded on power up. Softpatch modifications take effect immediately. From the main menu : NSI DSxx xPHASE STATUS=xxx [MORE] Press the [DIMMER] keypad.
- Page 13 NSI DS8/DS12 MODULAR DIGITAL DIMMING SYSTEM 3.33 Live Dimmer Status Press [MORE] to display the following status screen: DIM 01 = xx% DIMR SOURCE=yyy[MORE] This screen displays a variety of live functions of the dimmer. This screen not only displays the current control level for the dimmer, but also indicates where the control source level has been derived.
- Page 14 NSI DS8/DS12 MODULAR DIGITAL DIMMING SYSTEM 3.35 Custom Patch Minimum Level The minimum level menu will follow: DIM 01 MIN LEVEL = 00% [MORE] This level is essentially a warmer level. It can be used to keep filaments hot for quick lamp response, or for emergency circuits that you never want to go off.

- Page 17 NSI DS8/DS12 MODULAR DIGITAL DIMMING SYSTEM Please note that an 000.0 second hold time will hold the preset active forever, when run from the front panel menu display. An entry of 000.1second to 999.9seconds will hold the preset active for the selected hold time, then will automatically start the next or linked preset crossfade when the hold time runs out.
- Page 18 NSI DS8/DS12 MODULAR DIGITAL DIMMING SYSTEM 5.2 Analog Triggered Deep Presets This section assumes that you understand how to create and run presets, fade times, and links as described in the previous sections. If you have been poking around in the edit preset menus, you may have come across a menu after the LINK to PRESET menu called AUTO TRIGGER.
- Page 19 NSI DS8/DS12 MODULAR DIGITAL DIMMING SYSTEM ____________________________ Section 6 Dimmer Feedback The DS dimmer has several mechanisms for dimmer feedback. The most readily available feedback is the LED's on the front panel display. The green LED above each circuit breaker fades up and down proportional to the corresponding dimmer level.

Questions and answers
can I use an led in place of a par 38 in the ds-12 dimmer system
The NSI DS12 dimmer system is designed to control lighting loads rated for 115/120V and within the dimmer's wattage and ampacity limits. While the documents do not specifically mention compatibility with LED bulbs, using an LED in place of a PAR 38 bulb depends on the type of LED and whether it is dimmable and compatible with the dimming method used (e.g., phase-control dimming). Standard dimmer packs like the DS12 may not work properly with all LED bulbs, especially non-dimmable ones or those incompatible with traditional dimming systems.
Therefore, LED bulbs must be dimmable and confirmed compatible with the dimmer type used in the DS12 system.
