bringing each successive dimmer up to full and down again - perfect for
checking lamps, patches and dimmers! It can work as a "one cue"
controller, allowing you to send any combination of levels to any of
dimmers. This feature, SEND/EDIT SNAPSHOT, can be used either by
data from the front panel keys, or by recording a "picture" of the
DMX line. The Lil'DMXter provides a signal that may be used as
scope trigger, synchronized to the break/mark after break sequence.
The DMX512 standard is widely used in
lighting and effects. Different equipment uses the
standard for a wide variety of purposes. The DMX512 standard allows
variation of certain parameters. We allow you to vary five important
of the transmitted signal to help the Lil'DMXter mimic as many
as possible. We group these parameters into presets which we call
The Lil'DMXter provides you with nine flavors, three of them
Those parameters you can vary are:
The Lil'DMXter allows you to send

- Break Length
- Mark After Break Length
- Numbers of slots Sent

error, it warns the user. In addition to stepping from slot to slot,
the Lil'DMXter allows the user to jump to the next slot with
level equal to or greater than a preset search level. In VIEW
the unit measures and displays break length, mark after break length,
to break time, updates per second and number of slots per packet. It
also displays all of the start codes being received from the DMX line.

DISPLAY FORMATS SUPPORTED
The Lil'DMXter supports three
formats for slot levels. Two of them, decimal and hexadecimal,
the full 256 step resolution. The third, percent, provides a 0-100 step
scale similar to that used on most lighting consoles.
Have you ever had a haunted lighting
Have you had the problem of trying to determine whether it's the
or the dimmers? The FLICKER FINDER mode allows you to compare each
packet with a stored snapshot of the console's output. It also gives
a user selectable comparison window. The unit will count as an error
any slot level falling outside the comparison window. The Lil'DMXter

FLICKER FINDER allows you to calculate the system error rate.
Testing a cable for electrical continuity
is not the same as testing it for data transmission continuity. The Lil'DMXter
cables using actual data. It has a mode that allows you to test
when both ends are not available in the same place. This makes the unit
particularly useful in troubleshooting installations. It also tests the
optional link on pins 4 and 5. Although use of these pins is outside
DMX512 standard, there is considerable installed base of equipment
them, and you'll probably want to test them at some point.
MULTI CHANNEL MODE
DMX512 was conceived as a dimmer control
Today many different theatrical devices are controlled by DMX512. Many
of these devices, particularly moving lights, use more than one DMX
slot.. Our Multi Channel Mode moving light software will let you:

light features of our software. You may download the full manual from

the software allows patching of the intensity control channel to any

blocks, a simple auto patch routine will set up the patch with the

- Some multi channel fixtures use

New Hardware Features of Lil'DMXter2
The Lil'DMXter2 features an
low standby power consumption of 200µA. This means standby time
charges should be greater than 6 months. The Ram memory has been
from 8K to 32K bytes; the ROM from 32K to 64K bytes. Addition I/O has
added for expansions and special features. The DMXter2 has room to grow
with you and DMX512.

The Lil'DMXter2 is CE certified
European Union has established certain requirements that most
equipment must conform to when used within the EU. It has established
methods to determine that a unit does conform. Units that do conform
carry the "CE mark".
Goddard Design Co. is pleased to
that all Lil'DMXters are CE certified for direct connection to AC mains
To our knowledge, this unit is the only professional DMX512 test unit
does not require a wall transformer for charging.
