The Volt Meter of Digital Lighting Control

CE Mark For over fifteen  years the Lil'DMXter and the Lil'DMXter2 have been the standard of DMX512 testing.  The Lil'DMXter2 significantly expanded the unit's memory capacity, providing room for software expansion. The Lil'DMXter is simple to use. Only seven buttons run its menu-driven software. The Lil'DMXter speaks to you in plain English using a backlit 40-character display. It comes in a rugged water-resistant case, tough enough to ride in your tool kit or cable hamper. It runs on its own internal rechargeable battery. The AC charger is built in. The Lil'DMXter is the tool you need to work with digital lighting systems, color scrollers, moving lights, and anything that is controlled by DMX512.


The Lil'DMXter offers you four DMX512 transmit modes. You may ADJUST ONE SLOT. You may ADJUST ALL SLOTS to the same level. The Lil'DMXter can AUTOFADE thru a dimmer system, bringing each successive dimmer up to full and down again - perfect for checking lamps, patches and dimmers! It can work as a "one cue" lighting controller, allowing you to send any combination of levels to any of 512 dimmers. This feature, SEND/EDIT SNAPSHOT, can be used either by entering data from the front panel keys, or by recording a "picture" of the received DMX line. The Lil'DMXter provides a signal that may be used as a scope trigger, synchronized to the break/mark after break sequence.

The DMX512 standard is widely used in theatrical lighting and effects. Different equipment uses the standard for a wide variety of purposes. The DMX512 standard allows wide variation of certain parameters. We allow you to vary five important parameters of the transmitted signal to help the Lil'DMXter mimic as many products as possible. We group these parameters into presets which we call "flavors". The Lil'DMXter provides you with nine flavors, three of them user-defined. Those parameters you can vary are:

The Lil'DMXter allows you to send and receive any of the 256 allowed start codes.


The Lil'DMXter allows you to examine a controller's output and indicates whether a valid DMX512 signal is being sent. In VIEW LEVELS the unit displays received levels. The unit displays levels for four sequential slots at once. If the unit detects a reception 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 a level equal to or greater than a preset search level. In VIEW PARAMETERS the unit measures and displays break length, mark after break length, break 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. VIEW PARAMETERS also provides the error summary screen. This screen flags parity errors, framing errors, break too short, mark after break too short, overflow (reception of more than 512 slots) and broken line detection. Broken line detection is a proprietary Goddard Design Co. feature that detects if either of the two data lines is open during reception.


The Lil'DMXter supports three display formats for slot levels. Two of them, decimal and hexadecimal, display 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 system? Have you had the problem of trying to determine whether it's the console or the dimmers? The FLICKER FINDER mode allows you to compare each received packet with a stored snapshot of the console's output. It also gives you a user selectable comparison window. The unit will count as an error any slot level falling outside the comparison window. The Lil'DMXter displays the number of errors and their minimum and maximum values. Using 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 tests cables using actual data. It has a mode that allows you to test cables 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 the DMX512 standard, there is considerable installed base of equipment using them, and you'll probably want to test them at some point.


DMX512 was conceived as a dimmer control protocol. 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: The above is a brief overview of the moving light features of our software. You may download the full manual from our Web site.


How would you like to have a backup DMX512 controller? ShowSaver allows your Lil'DMXter to work as a backup device.

ShowPlayer Option

Add automatic changeover-to-backup-mode to your Lil'DMXter.  Store up to 64 cues, assigned to any of 1000 possible cue numbers.  Use an external device to trigger a sequence, or run cues based on time.  ShowPlayer is a software option that expands the capabilities of your unit.  (See separate data sheet)


The Lil'DMXter is available with a factory installed option that allows it to transmit and receive both DMX512 and Colortran (CMX) protocols in all its functions - including ShowSaver. The protocol selection is made and displayed thru the unit's menus. CMX Option is available for new and existing units.


All Lil'DMXter's provide a synchronization output that may be used to trigger an oscilloscope to view the unit's output. Synching a scope to an unknown source of DMX512 is notoriously difficult. For occasions when this is necessary, the RECEIVE SCOPE TRIGGER hardware allows you to synch to a received DMX512 signal from any source. This option provides the hardware; the software is included in all units. The hardware is an external scope trigger generator card .

The RECEIVE SCOPE TRIGGER option will allow you to:

The RECEIVE SCOPE TRIGGER hardware option is not for general DMX512 users. This is an analytical test function valuable in the R&D lab and for serious component level troubleshooters.

New Hardware Features of Lil'DMXter2

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

The Lil'DMXter2 is CE certified

CE MarkThe European Union has established certain requirements that most electronic equipment must conform to when used within the EU. It has established testing methods to determine that a unit does conform. Units that do conform may carry the "CE mark".

Goddard Design Co. is pleased to announce that all Lil'DMXters are CE certified for direct connection to AC mains power.  To our knowledge, this unit is the only professional DMX512 test unit that does not require a wall transformer for charging.
