MIDI Status LED
On Power Up= Flashes RED/GREEN 6 times.
When any Midi Command on the selected Channel is detected= Flashes GREEN one time
When any Midi Command is detected that is NOT on the selected Channel= Flashes RED one time
While the RESET Switch is Depressed = Steady RED
Midi IN Jack
This is connected to the Midi Device that is used to control the EX-100. This is an INPUT.
Midi Thru Jack
This passes all of the Midi Commands straight through the EX-100. This is a buffered output.
DMX Outputs
There are two separate DMX Outputs, but have the same DATA on both of them. This allows you to
have two separate runs for each side of the stage. DMX devices are “daisy chained” together. A
maximum of 32 DMX devices can be daisy chained to each output. Each output run, should be
terminated with a 120 ohm resister on the output of the last DMX device in the “daisy chain”. The two
DMX outputs are NOT isolated. They share a common ground.
Reset Switch
The RESET switch does two things. While fully depressed, it outputs maximum brightness for DMX
channels 1-255 (255). When released, it turns all DMX (1-512) channels OFF(0). This is a big help when
trouble shooting your light system. The MIDI Status LED turns solid RED while the RESET switch is
depressed. The EX-100 always outputs an OFF (0) condition for DMX channels 256 through 512.
EX-100 Midi Commands
The EX-100 allows you to control ONLY DMX channels 1 through 255. DMX channels 256 through 512
are NOT accessible with the EX-100. The EX-100 outputs an OFF (0) condition for DMX channels 256
through 512.
The Midi “NOTE ON” command, which consist of three consecutively transmitted bytes, is used to
control DMX channels 1-127. The format is as follows:
