Overview
The Gizmo is a DMX512 test tool with features useful for lighting system setup, testing, troubleshooting,
and commissioning. With the Gizmo you can transmit, receive, save, playback scenes and perform a
variety of data and cable tests. It is housed in a rugged chassis made of 0.1" thick aluminum. A fitted
carrying case and wall transformer/battery charger are included with each Gizmo. Direct channel access
while sending or receiving DMX512 signals is possible through the use of the numeric keypad. The display
is a back lit 16 character by 2 line LCD. The Gizmo has a fully opto-isolated DMX512 input. The DMX512
output can function as an isolated pass-thru which also re-times the signal.
Power
The Gizmo is powered by a re-chargeable internal battery or from the included wall transformer. The wall
transformer can be used to operate the Gizmo and to recharge the battery simultaneously.
When the wall transformer is connected, the Gizmo will be on regardless of the position of the battery
switch on the lower edge of the unit. Under battery power, the Gizmo can be turned on and off using the
switch.
The battery should be charged overnight to achieve a full charge (about nine hours). Note that to charge
the battery, the Gizmo must be connected to the wall transformer and the battery switch MUST be in the
ON/CHARGE position. From a full charge, the Gizmo should provide two to four hours of continuous use.
Notes On The Battery
The Gizmo’s internal battery is a NiMH 9 volt type. From a full charge, it will typically last a full day’s use
depending on how much of the time is spent transmitting and whether the display backlight is on or off.
User setup items and the 100 backup scenes are recorded in non-volatile memory which requires no
battery to be retained.
In order to charge the battery, the Gizmo must be connected to the included wall power supply and the
battery switch MUST be in the ON/CHARGE position. When the battery switch is in the OFF position, the
Gizmo will operate from the wall power supply, but the battery is NOT being charged.
If you need to use the Gizmo under battery power and do not have time to charge it, a standard 9 V
alkaline battery may be installed. It is important to note that the wall transformer MUST NOT be connected
to the Gizmo while an alkaline battery is installed. DAMAGE TO THE GIZMO AND/OR THE WALL
TRANSFORMER COULD RESULT. To change the battery, remove the two screws on the back of the
Gizmo. Remove the rear cover and replace the battery as needed.
If the Gizmo is being used on the bench, you may wish to power it from the wall transformer all the time.
To do this, simply connect the wall transformer to the Gizmo and put the Gizmo’s battery switch in the OFF
position.
If you need a replacement wall transformer, contact Doug Fleenor Design. For those who want to come
up with their own source, the power supply provides 15VDC at 2/3A. The connector is a 2.5mm type with
the center conductor as positive.
