Setting Unit IDs

Top  Previous  Next

Each Light-O-Rama controller must have a unique assigned unit ID, identifying this particular controller.  The reason for this is that every Light-O-Rama controller in a network can see every lighting command message that is sent over the network, not only the lighting commands sent for that controller.  So, all of the commands contain a unit ID, and a controller only acts upon a command if the unit ID of the controller matches the unit ID of the message.

 

A unit ID is a two-character field.  Each character can have any of the values 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F.  For example, a unit ID might be "03", "07", "25", "37", "6B", "C8", or "DA".  However, certain values are reserved, and so not allowed (specifically, "00", and "F1" through "FF").

 

Some Light-O-Rama controllers have selector switches that allow you to directly set their unit IDs.  In that case, simply use a small screwdriver (making sure that the unit is not attached to power) to dial the switches to the desired unit ID.

 

Other controllers do not have selector switches.  To set the unit IDs of these controllers, you can use the LOR Control tab of the Light-O-Rama Hardware Utility:

 

Connect the Unit to the Computer
Select the Comm Port
Set the ID of a New Unit
Change the ID of an Existing Unit
Troubleshooting

 

Connect the Unit to the Computer

 

The first step in setting a Light-O-Rama controller's unit ID using the Hardware Utility is to connect the unit to the computer, for example using an SC485 adaptor or a USB-RS485 adaptor.  Make sure that the selector switches are correctly set for the type of cable used (units are shipped ready to use data cables).  Plug the unit into an AC outlet, and turn the unit on.

 

Select the Comm Port

 

After you have connected the unit to the computer, select the comm port that the Hardware Utility should use to communicate with the controller.

 

Set the ID of a New Unit

 

If this is a new unit that has not previously been assigned a unit ID, use the "Set New Unit ID" section of the LOR Control tab of the Hardware Utility.  Simply select the unit ID you want to assign, and click the "Set Unit ID" button.

Change the ID of an Existing Unit

 

If you have previously assigned a unit ID to this unit, but want to change it, use the "Change Existing ID" section of the LOR Control tab of the Hardware Utility.  Select the unit's current ID in the "Old Unit ID" list, and the unit ID that you want to change it to in the "New Unit ID" list.  Finally, click the "Set Unit ID" button.

Changing a unit ID

 

If you do not remember the unit's current unit ID, or if the controller doesn't seem to be reacting to its current ID, you can change it to a new unit ID by selecting "Any Unit" in the "Old Unit ID" list.  However, be very careful.  If you select "Any Unit", then all units that are connected to the PC will have their unit IDs changed.  So, make sure that you have only the one controller (whose unit ID you wish to change) connected.

Troubleshooting

 

If, while setting a Light-O-Rama controller's unit ID, you receive an error saying that the unit cannot be located, the first thing to do is to check all connections and to make sure that the correct comm port is selected.  If the Hardware Utility still cannot locate the unit, check the Communication LED on the unit.  When the unit is disconnected from the data cable the LED should blink; when it is connected and the Hardware Utility is running with the correct comm port selected, the LED should stop blinking, turning on steady.

 

If the Communications LED continues to blink regardless of the steps taken, then there may be a problem with the cable, the adaptor, the controller, or the PC's comm port.

 

If the LED stops blinking but you still get an error when attempting to set the unit ID, then there may be a problem with the adaptor or the controller, or the PC may have a communications driver that is not completely compatible with Light-O-Rama.  However, you may still be able to set the unit ID by checking the "Ignore Errors" box and then trying to set the unit ID again.  If you do check the "Ignore Errors" box, make sure that the unit ID has been set correctly by running some tests on the controller.
