DMX512 R EFERENCE G UIDE

Note: It is recommended that all luminaire input connectors be orientated facing stage left, or at least
in the same direction by hanging position.
b. Make sure that double truss hook or clamp (VL7) is oriented and bolted to pan tube
correctly.
Luminaire addresses are usually decided upon prior to the set-up of equipment. The lighting
plot may contain this information.
c. Loop safety cable around pipe two or three times leaving as little slack as possible and
attach clip to opposite side of pan tube or chassis. Ensure that safety cable will not
interfere with luminaire movement.
Step 8. Hang and configure Smart Repeater units.
Note: When hanging a repeater, hang so that the red and green comm LED indicators will be visible to
the tech, not the audience, when the truss is raised (at trim).
a. Attach Smart Repeater units to pipe or truss using two Series 200 truss hooks (turn
quarter-turn fastener clockwise). Refer to "Series 200 Hanging Hardware" on page 60
for more information. Do not over-turn quarter-turn fastener or truss hook receptacle
assembly may be damaged.
b. Attach safety cable to handle and verify that unit is securely fastened to pipe or truss.
c. Set thumbwheel to correct system address.
Note: The Smart Repeater also requires a DMX mode, which is set at the thumbwheel. For more
information on setting DMX modes, see
"DMX512 Modes" on page 10 .
Step 9. Connect APS trunk cables and Socapex cables.
Note: When using only VL5 and/or VL5B luminaires, industry-standard Socapex cables can be used
in place of APS trunk cables.
a. Connect plug end of APS trunk cables to SixPack chassis in modular rack outputs.
b. Connect receptacle end to Smart Repeater units.
Step 10. Connect cables.
a. Connect plug end of Series 300 lamp cable to Smart Repeater unit.
b. Connect receptacle end of lamp cable to Series 300 luminaire. Make sure to use correct
length of lamp cable to avoid having too much excess. Avoid using many short lamp
cables connected together since the more interconnections that exist, the more noise and
maintenance problems that may develop. Dress cable to truss using either tie string or
PVC tape. Ensure that cable does not impair operation of luminaires.
Note: To avoid noise problems, make sure to not use the older, unshielded, gray-jacketed Series 300
lamp cable with VL5Arc and VL6 luminaires.
