Verify that your device shows up as a serial port in your computer (Device Manager in Windows, System Profiler in OS X). Verify that you&#039;re using a driver from FTDIChip, or one that&#039;s included with your computer. You should <u>not</u> use a driver from Enttec, even if this device is 100% compatible with the Enttec Pro protocol. You can download drivers from the FTDIChip web site. Download the <span class="a-text-bold">DMXking ultraDMX Config Utility </span>from the DMXking web site (Windows only). This can be used to verify connectivity to the ultraDMX Micro and modify timing settings if you have lights that aren&#039;t 100% DMX-compliant. Set up your light fixture in the most basic way first, plug the ultraDMX Micro directly into a single light fixture, verify that the light fixture is in DMX mode (usually it says d.001 or something like that on the display) and confirm its start address (1 through 512). On Windows you can use the DMXking Config Utility to test the light fixtures by going to the <span class="a-text-italic">DMX Display</span> option under the <span class="a-text-italic">View</span> menu. Once in there switch to the <span class="a-text-italic">Transmit</span> view (to send data <span class="a-text-bold">to </span>the light fixture). You can then click the <span class="a-text-italic">All 255</span> button, most lights will show some activity. Note that it brings up all addresses to the full brightness. If you see activity on the light fixture then you have verified that your operating system can communicate with the ultraDMX Micro, that the ultraDMX Micro is working, and that your light fixture is working. Once that is working you should be able to start using a real light design software. A good starting point is Freestyler, QLC+ or Lightkey, but there are numerous options.
