“bounce” condition may be imposed on several of 
the chase patterns by setting one of the DIP 
switches.  The bounce condition causes the chase 
pattern to run in alternating directions. 
 
The chase step time may be controlled for up to 64 
seconds per step.  Step fade time is proportional to 
the step time.  If a channel is in the relay mode 
during chaser operation - it will “snap” on and off 
(zero fade time).  The tables below show the details 
of chaser settings.
