Light-O-Rama controllers are connected to a data network for communications. In typical configurations the controllers are daisy-chained so each requires a unique Unit ID. How that unique Unit ID is set depends on the type of controller. Some controllers allow configuring the unit ID from the Hardware Utility that’s part of the ShowTime Sequencing Suite. Other controllers allow setting the Unit ID from an LED display on the front panel. Still other controllers are designed to set the Unit ID by DIP (Dual Inline Pin) switches or rotary dials.
Setting the Unit ID via DIP switches on appropriate controllers (CTB04PC, CMB24D, etc)
It’s easy to get intimidated setting the controller Unit ID via the little on/off switches on the circuit board. The good news is it typically only has to be done once.
The manual goes into great details on how to set all the switches. Here’s the quick-and-dirty.
Locate the switches on the controller. It should look like this if the controller is set for Unit ID 02.
Look carefully and orient the controller to see the switches as shown in the above image (click the picture to make it larger if needed). On one side of the switch set there’s a marking for off/on.
ON is up
off is down
Each little switch is marked 1-12. Using something small like a toothpick, set the switches as needed for the Unit ID required. To make it easy, we’ve created a chart showing how to set Unit ID 01-09.
|Unit ID||switch number|
See the appropriate product manual for how to set other unit IDs. The manual will also discuss what the other switches are for.
