Lg-DMX/DC Configuration
There are three rotary switches used set the DMX-512 address of the Ld-DMX/DC. You set the address by
simply dialing in the DMX address of the first output to these three switches. You can use American-style (1-512)
DMX addressing, or European-style (0-511) DMX-512 addressing, depending on the state of Dipswitch #7.
Th eight position DipSwitch is used to configure the other options on the Lg-DMX/DC:

DipSwitch 3: Update rate
The Lg-DMX/DC can be set to update the outputs at a variety of rates from about 60 Hz to about 15
KHz. You can adjust the frequency as needed to provide the best dimming and quietest output to your
loads. Most light dimmers are updated at the line frequency of the local power. In most cases this is either
100 or 120 Hertz (update rate is twice the line frequency). The Lg-DMX/DC’s higher frequency update rates
can be used to keep LEDs from strobing, or to reduce audible interference to a nearby sound system.

DipSwitch 4: Disable Under Test
The Lg-DMX/DC can be set override the DMX-512 it receives when any output is being tested.
a) If off, then all outputs will be forced ‘off’ when any output is being tested. Any output(s) that are
‘under test’ will be forced to 100%.
b) If on, then the outputs will continue following the DMX-512 data that is being received. Any out-
put(s) that are ‘under test’ will be forced to 100%.
