Optional Jumper Settings
When the control box jumper is in the "Phantom Mode" setting (see diagram
below) only the center 6 arrays will be utilized during the Left, Center Out,
and Right patterns. The outer two heads or arrays with flash alternately.
These Traffic Directors have 8 heads or LED arrays.
The TD77-2 control box and the ULB42-TD-2
control box are identical except for the factory
default setting of a jumper located inside the
control box. This jumper will control the output of
the two arrays on each end. The TD77-2 comes
with the jumper defaulted for standard operation.
Optionally you may wish to set the jumper so that your arrowstick operates in "Phantom" mode. In
the “Phantom” mode, the end lights are not part of the “traffic directing” patterns. When the Alt
button is pressed, both of the end lights will flash back and forth in a “warn” type display. (In the
"standard" mode, the end lights will follow the normal “traffic directing” pattern you select on the
control box.) If you wish to operate your traffic director in Phantom Mode, (6-head traffic directing),
follow the instructions below to remove the cover and change the jumper setting. If the standard
mode is acceptable, skip this section.
