and tree. They are completely pre-wired and connect to the interface box and junction box on the

starting line. Locate the interface box in the tower and run the main wire out to the center of the track.

The junction box has cables going to the respective pre-stage and stage emitters and receivers. All

connections are all labeled and can be routed to their respective detector and emitter location. The

Christmas tree can be moved at any desired location. It should be out at least 30 feet and many tracks

are now out 35 to 40 feet.

**Temporary Track – in lieu of a start line junction box, on temporary systems, we install additional

cable for start line infrareds and put a convolute plastic protection tube over the cables.

11) Next locate the mph junction boxes. These junction boxes should be located at the 1320 foot

locations and have enough wire to move them off the edge of the track. We have a 12 position terminal

strip inside which contains the wires for the mph and finish line detectors as well as the win light and

stop light for that lane.

Steps 12, 13, & 14 are prewired & precut on all temporary tracks.

12) There are two lengths of wire that will be used to reach the finish line on both sides of the track.

One length is (1550 on ¼ mile track or 850 on 1/8 mile track) for the far lane of the track. The other

cable (1450 feet on ¼ track or 750 on 1/8 mile track) is for the tower lane or near side of the track. Use

cable appropriately. Start with long run.

**Temporary Setups –Your cables have connectors with 2 pieces 1330 feet each on ¼ mile tracks or 2

pieces 665 feet each on 1/8 mile tracks. The remaining cable goes into your tower extension.

13) The junction box has a wiring schematic under the cover. The wires should be bared back

about ¾ inch twisted and folded over and twisted again and then soldered. Make the solder joint small

enough to get into the terminal strip and then fasten with the screw. The drain wire (bare wire) must be

attached to a separate terminal. At the finish line, you will need a relay to power your win lights and

stop light. It should not draw more than 40 milliamps at 12 volts. We have solid state relays that are

low powered. Run a wire out of the 1320 foot junction box to the relay where the win light is located.

Do not mount relay in the junction box.

**Temporary Tracks – Cabling is pre-wired**

14) The other end of each of these wires is to be terminated in the tower inside of the interface box.

Wiring is as follows:

Red and Blue Wire -- Positive 12 Volts D.C.

Black and White Wire -- Ground

Brown and Green Wire -- Signals – To Terminal Strip

Brown is MPH -- Green is Finish

Yellow Wire -- Negative 12 Volts D.C.

Orange Wire -- Win Light -- Terminal Strip

Note: The 60 foot wires require only 3 conductors. Red is positive, Black is ground, and the green

wire is the signal wire. It is probably prewired.

15) The Timeslip Printer can be located up to 8000 feet away and requires a 9 PIN SUB D

connector at each end . We usually prewire-or call Portatree for pinout specifications.

Note: Unless ordered, only a 6 foot cable is included with the printer.

16) Before connecting the computer, power up the interface box by connecting the red wire to
