A word on termination: DMX is a resilient communication protocol,
however errors still occasionally occur. Termination reduces signal errors, and therefore best
practices include use of a
terminator
in all circumstances. If you are experiencing problems with
erratic fixture behavior, especially over long signal cable runs, a terminator may help improve
performance.
To build your own DMX Terminator: Obtain a 120-ohm, 1/4-watt
resistor, and wire it between pins 2&3 of the last fixture. They are also readily available from
specialty retailers.
Master and slave: select one machine as master, press the menu to choose the
function you want. Press other machines’ address to be DMX state. Use signal
cable to connect machines one by one. Then slave machines will run the same as
master machine.
Use controller to control lot of machines: if all machines are set the same menu
data, or different manual data, after use signal cable to connect to controller, all
machines will be controlled by controller. (before connect to controller, all
machines should be in the same channel mode 9ch or 4ch).
Section 3. Troubleshooting
Problem
Probable Cause(s)
Remedy
No power to fixture
Check power cables
Primary fuse blown
Replace fuse
No response from
fixture when power
is applies
Secondary
fuse
blown
Replace fuse
Controller
not
connected
Connect controller
Incorrect
addressing of the
fixtures
Check address setting on fixture and controller
Bad
data
link
connection
Inspect cables and correct poor connections
and/or broken cables.
Conflict
between
tracking and vector
control
Eliminate scene cross-fade on controller
Data
link
not
terminated
Insert termination plug in output of last fixture
Fixture resets but
does not respond
correctly
to
controller(DMX
mode operation)
Defective fixture or
2
devices
transmitting on link
Bypass fixtures one at a time until normal
operation is regained: unplug both connectors
and connect them directly together
