16. Before connecting the computer, power up the interface box by connecting the red wire to
positive and the brown wire to ground 12 volts D.C. An A.C. to D.C. converter can be used but it
must have a minimum of 2 amps of supply current. Do not use an inexpensive supply or you may
encounter start up problems with the Portatree Professional. We recommend an automotive battery
with a 6 amp battery charger continually charging the system.
NOTE:
1. Do not power up the Portatree Professional computer until all tree and track
connections are properly attached to the sub d connectors.
2. Do not use the small transformer to power up the Portatree Professional in
conjunction with the interface box. The interface box will power up the Portatree
Professional.
17. After powering up the interface box you will have power to all of your detectors. You can align
all of the detectors by sweeping left/right and up/down. The red L.E.D. will illuminate when the
detector is aligned. Read the literature to efficiently align them. They may or may not require
sensitivity adjustment.
18. The computer can be connected after the detectors are all working. Disconnect the 12-volt power to
the interface box and then plug the two 25 pin sub d connectors into their respective positions.
Power up the interface box. Read the manual on the PORTATREE PROFESSIONAL
COMPUTERS OPERATION. SET THE COMP UTER ACCOR D INGLY. PLEASE WATCH TH E
VIDEO SUPPLIED WITH THE SYSTEM AS IT WILL ANSWER MANY OF YOUR
QUESTIONS.
19. Now the starting line can be set using the pre-stage and stage lights on the Christmas Tree. Use
the Portatree video to understand how rollout is set and build a rollout wheel to set the rollout. Aft er
the rollout is set and the detectors are securely fastened. You must keep the detectors out of the
direct sunlight and you must keep them out of heavy moisture condition. We suggest covering the
detectors with a white PVC pipe.
20. All detectors must have covers over them to keep them out of the weather and to keep the sun
from directly contacting them. The starting line takes a lot of time to set up correctly so you may
want to permanently fix them and place a rigid steel cover over them.
PLEASE BE VERY CAREFUL DURING INSTALLATION TO AVOID LENGHTY
TROUBLE SHOOTING. IF YOU HAVE ANY QUESTIONS,

Sand Drag Tracks require the same accuracy as asphalt drags so it is very important for you to take
you time setting up the system. Make sure that you fully read and understand the photo cell alignment
procedures so that you will get proper and consistent results.
