The wiring diagram shows a typical installation using the 

PRO-CUBE 

ä

 to control a dual cylinder 

throttle stop 

Pro-Stage II

 

 system for starting line and ET control.  Though it is possible to use a single 

cylinder throttle stop for both, the dual cylinder approach allows two different throttle settings, one for near 
idle on the starting line and the other for down track ET control (usually ¼ to ½ throttle). 

            NOTE:

  TO  PREVENT  ACCIDENTAL  REACTIVATION  OF  THE 

Pro-Stage

 

™  DURING  THE 

RUN,  THERE  IS  A  15  SECOND  ACTIVATION  LOCKOUT  OF  THE 

Pro-Stage

 

™  FROM  THE TIME 

THE TRANSBRAKE RELEASES.  SIMPLY USE THE 

RESET 

SWITCH TO CLEAR THIS LOCKOUT IF 

YOU HAVE ACTIVATED THE TRANSBRAKE JUST BEFORE STAGING. 
 

Crossing-Over and Interfacing:

 

 
 

When you enter a slower opponent’s dial-in, it is assumed that you want to “cross-over” and trigger 

off your opponent’s top bulb.  If you do not want to cross-over, simply set the opponent’s dial-in to 0.00 (or 
any number less than or equal to your dial-in).  The diagram below illustrates a typical cross-over application 
in which both 

DELAY 1

 and

 DELAY 2

 are activated. 

 

The  second  delay 

(

DELAY  2

)  is  used  only  if 

you  hit  the  tree  a  second 
time.  In  Dual  Trigger  mode 

DELAY  2

  is  controlled  by 

TRIGGER 2

In  Single  Trigger 

mode  press 

TRIGGER  1

 

switch  and  release  it  to  start 

DELAY  1

,  press  and  release 

it again to start

 DELAY 2

 

 
 

The 

PSTG/BMP

  switch  is  used  for  the 

Bump-Down

Ò

  function  as  well  as  to  activate  the 

Pro-Stage

  output.  You  can  hit  the 

PSTG/BMP

  switch  any  number  of  times  to  reduce  the  delay  and 

improve  your  reaction.    Each  time  you  bump-down,  the  programmed  amount  of  time  is  subtracted  from 
either your first hit (

DELAY 1

) or the second hit (

DELAY 2

), whichever occurred last. 

 

Run Information: 

 
 

If you hit the tree twice or use the 

Bump-Down

Ò

 feature, reaction time information and bump-down 

counts will be automatically displayed approximately 15 seconds after you launch.  The reaction time display 
will  indicate  which  side  of  the  tree  you  launched  on  as  well  as  the  difference  in  your  reaction  times.  The 
quicker reaction is indicated with 0000 in the window its corresponding dial-in, and the differential (slower 
reaction)  is  displayed  with  its  corresponding  dial-in.    The  bump-down  display  simply  indicates  how many 
times you bumped down. The bump-down count for the transbrake release is displayed in the left window 
and  the  bump-down  count  for 

TIMER  1

  is  displayed  in  the  right  window.  The  reaction  and  bump-down 

information displays alternate about every four seconds until you clear it by using the 

RESET

 switch.  Since 

the information is not saved, you may want to record it for future reference. 
 

 

 

EXAMPLES 
 
Example 1: 

 

Your dial-in is 9.30, your opponent's dial-in is 10.92.  Your delay time is 1.035 seconds and you're 

using  two  trigger  switches  in  Dual  Trigger  interface  mode.    Enter  9.30  for  your  dial-in,  10.92  for  your 

TRIGGER SWITCH IS RELEASED

ON OPPONENT’S TOP BULB.

CROSS-OVER DELAY STARTS.

TRIGGER  SWITCH  IS  RELEASED

ON DRIVER’S TOP BULB.

DELAY 2 STARTS.

CROSS-OVER DELAY ENDS

AND DELAY 1 STARTS

AUTOMATICALLY.

DELAY 2 FINISHES FIRST AND LAUNCHES

CAR.  TRANSBRAKE LOCKOUT DELAY

STARTS AUTOMATICALLY.
