To begin you need to understand what a patch is. In a lighting system you will have many lighting fixtures that you

“plug” into dimmer circuits. You may have several light fixtures “plugged” into a single dimmer circuit because they are being used together and do not need individual control.

Often many fixtures on many dimmers are doing the same thing and you would like to have all of them controlled together. An example of this would be the many dimmers that control the auditorium house lights. In many cases it would be nice to control all of the house lights on one

Channel/fader. To do this, dimmers are Patched (plugged into) to a Channel/fader via the patch screen. Although the

PATCH screen lists DMR (dimmers) this is a DMX control address and in addition to dimmers can be used to control any device that uses USITT DMX512 control protocol for its operation. This could include items like; color scrollers, moving lights, fog machines, relay panels, etc.

To get to the PATCH screen you need to push the

[Patch Profile] key once. The PATCH screen will appear on your display. The Bijou has two patch tables that can be modified by the user and one default (One-To-One) patch that can not be modified. The patch allows you to assign one or more dimmers to a channel. You can also set a maximum output level for a dimmer. And you can assign a fade in curve (Profile, see next section) for each dimmer. In addition dimmers can be ‘Parked’ or changed to Non-Dim units in this screen.

To select PATCH Page 1 or PATCH Page 2 for modification use the [F2] key followed by a [1] [Enter] or a [2] [Enter].

NOTE: neither patch will be in use by the board until you go to setup and make it the “Active Patch”. To do that you would need to hit [Setup] Default Settings 1 [4] Active Patch [0] One-

To-One or [1] PATCH Page 1 or [2] PATCH Page 2 then

[Enter] to confirm the active patch. If you are just learning the system leave the default One-To-One patch as the active patch for now.

On the Patch screen you will see ninety dimmers listed at a time, with DMR 1 - 90 shown on the first screen. DMR

(dimmers) are shown as blue #’s. Using the [Page Up] and

[Page Down] keys will let you see up to 1024 dimmers.

NOTE: The number of dimmers and DMX devices in your system will limit the number of dimmers you will need to patch.

DMR (dimmers) are assigned to CHN (Channels/faders shown as green #’s) using the [At] [Thru] [And] [Except] [At] and [Enter] keys. To make CHN 1 control DMR 3 you would hit; [3] [At] [1] [Enter]. This puts the control of dimmer 3 onto channel 1 with an output of 100% and Profile 1. As the most common output level for dimmers is 100%, the LEV (white) row is left blank unless you input a level other than 100%.
