Automatically Control the Bumpers 
This option tells the Duo software whether there are any automatic bumper systems being controlled by the system. 
Automatic bumpers are either controlled via a relay switch closure across pins 4 and 12 in the Machine Interface Port 
(Usually AMF Bumpers systems) or by a central controller connected to the host computer (Usually Brunswick 
Bumper systems). For more information on centrally controlling bumper systems such as Brunswick Ball Wall, see 
Appendix B. 
If this option is enabled, then the system will display a Bumper Icon for any bowler who has bumpers specified from 
the Control Computer. 
Connected to a Control Computer 
Aside from their Stand Alone functionality, the Duo hardware is able to connect to optional computers on the front 
desk to allow you to control all aspects of the lanes from the front counter, as well as the other optional software 
modules such as Point Of Sale and League Secretary. In order to use these features the Duo hardware must be told 
to look for the presence of the front end computers. 
If control computers are present, enable this setting. If the Duo units have no computers attached and are operating 
in Stand Alone mode, disable this setting. 
Scorer Cycles Light Balls 
The desire for Light Ball Triggering comes from the situation where a light children’s ball is sometimes not thrown with 
enough force to activate the Pinsetter’s cycle. Most newer Pinsetters such as the GS series already include an 
electronic sensor to detect the ball and perform a cycle automatically. In this case, disable Light Ball Triggering in the 
Set Options screen. However, older Pinsetter models may not include this feature. 
Although the Duo system does not need to have light ball triggering in order to report the score, it does have the 
ability to cycle the machine on a time delay after the ball passes the ball detectors built into the Duo Hardware 
Module. 
Light Ball Triggering Safety 
Once you enable this feature you are presented with a Warning screen regarding the safety of any light ball triggering 
system. You must read this message in full by pressing on the M for Read More button.  
Once this is done, the I Accept option becomes enabled.
