Instructions

Programming Example
If you want to set the dwell to 20, you should:
1. Make sure the marker is powered off and the tournament lock is
disabled.
2. Pull the trigger and push the power button to turn on the marker.
3. The LED shows a rainbow sequence then stops on solid green. This is the
debounce mode.
4. Quickly pull and release the trigger 1 time to switch to the dwell mode.
The LED will show purple.
5. Pull and HOLD the trigger until the LED turns off.
6. Release the trigger. The LED will blink out the current setting.
7. When the LED stops blinking, enter the new setting by pulling the trigger
20 times.
8. Wait until the LED turns back on, indicating programming has been
completed.
9. Turn the marker off.
Program Reset
To reset all settings to factory defaults, hold down the eye button for 10 seconds while
in programming mode. The LED will rapidly cycle through every setting color to
indicate that the process has completed.
Settings
Debounce – The THump board features an interrupt based debounce algorithm that
effectively “scans” the trigger over 2 million times per second. It runs this completely
independent of code execution on the microcontroller so your trigger pulls are always
registered. The debounce setting is in increments of ½ milliseconds. Users should be
aware that low debounce settings may cause the marker to read switch bounce as
additional pulls, falsely generating shots or near full-automatic fire. The setting ranges
from 1 to 50 and is defaulted at 20 (10 ms).
Dwell – The amount of time the solenoid is energized each time the marker is fired. The
default is 18 ms. The range is 10 to 30 ms. Too low of a dwell may lead to inconsistency
or drop-off. Too high of a dwell can cause bad air efficiency.
Loader delay – Adds a slight delay after the eye has seen a ball and the bolt is cycled,
causing the gun to fire. If not using force fed loaders, it may be necessary to increase
this setting to prevent chopping. A setting of 1 means no loader delay, which is the
astest. The default is 2 and may be set from 1 to 25.
f
AMB (Anti-mechanical bounce) – Allows the user to adjust the anti-mechanical
bounce feature. Mechanical bounce occurs due to the kick generated during each shot
and can cause the marker to “run away” on the first few shots. AMB helps stop markers
from going full-auto when the trigger is pulled very slowly. The default is 2 and may be
set from 1 to 5 (1 being off). AMB is only used in fire modes 1 and 2 (semi-automatic
unlimited and adjustable).
ABS dwell – Amount of dwell time added for an ABS (anti-bolt stick) shot. The range
is from 1 to 15 additional milliseconds of dwell. The default is 5. ABS programming
helps to eliminate first shot drop-off. First shot drop-off occurs when the lube and o-
rings settle or “stick” inside the marker after it has been sitting. The next shot fired will
be lower in velocity because the bolt has to break free. ABS will slightly increase the
dwell to compensate if the marker is left sitting for 15 seconds.
Fire mode – Included are twelve (12) different fire modes (default is 1):
1. Semi-automatic, unlimited rate of fire
2. Semi-automatic, adjustable rate of fire
3. PSP auto-response
4. PSP mild ramping, adjustable ramp start
5. PSP max ramping, adjustable ramp start
6. PSP Z-burst
7. NXL full-automatic
8. Auto-response
9. Mild ramping
10. Max ramping
11. Z-burst
12. Full-automatic
Setting 1 is normal semi-automatic with an unlimited rate of fire while the eyes are
enabled. When the eyes are turned off, the max rate of fire is set to 20 balls per second.
Setting 2 is semi-automatic with an adjustable rate of fire. It limits the maximum balls
per second that can be fired. The cap is set by the max rate of fire setting.
Setting 3 is the PSP auto-response fire mode that works as follows:
• The first 3 shots of a string are semi-automatic
• After the 4
th
shot the marker will fire on the pull and release in auto-response
mode
• If the user stops firing for more than 1 second, the 3-shot semi-automatic
count starts over
Setting 4 is the PSP mild ramping fire mode that works as follows:
• The first 3 shots of a string are semi-automatic
• After the 4
th
shot the marker will ramp based on the speed of the trigger pulls
as long as the user pulls the trigger faster than the ramp start setting.
• If the user stops firing for more than 1 second, the 3-shot semi-automatic
count starts over
Setting 5 is the PSP max ramping fire mode that works as follows:
• The first 3 shots of a string are semi-automatic
• After the 4
th
shot the marker will ramp up to the loader’s maximum speed or
the maximum rate of fire as long as the user pulls the trigger faster than the
ramp start setting.
• If the user stops firing for more than 1 second, the 3-shot semi-automatic
count starts over
Setting 6 is the PSP Z-burst fire mode that works as follows:
• The first 3 shots of a string are semi-automatic
• After the 4
th
shot the marker will burst fire from 2-3 shots per pull depending
on how quickly the trigger is pulled and released
• If the user stops firing for more than 1 second, the 3-shot semi-automatic
count starts over
Setting 7 is the NXL full-automatic fire mode. It functions similarly to the PSP fire
modes except, after the 3
rd
semi-automatic shot, the user may pull and hold the trigger
for the marker to fire in full-automatic.
Setting 8 is the normal auto-response fire mode. The marker will fire on each pull and
release of the trigger, generating two shots per full pull cycle.
Setting 9 is the normal mild ramping fire mode. The marker will fire in semi-automatic
unless the user pulls the trigger faster than the ramp start setting. Once the ramp start
setting has been achieved the marker will mildly ramp, generating additional shots
depending on how fast the user pulls the trigger.
Setting 10 is the normal max ramping fire mode. The marker will fire in semi-automatic
unless the user pulls the trigger faster than the ramp start setting. Once the ramp start
setting has been achieved the marker will ramp up to the maximum feed rate of the
loader or the maximum rate of fire setting, whichever is lower.
Setting 11 is the normal Z-burst fire mode. The marker will burst fire 2 times or more
for every pull and release of the trigger, depending on how fast the user pulls the trigger.
Setting 12 is the normal full-automatic fire mode. As long as the trigger is depressed the
marker will fire in full-automatic.
Fire mode max rate of fire – The max rate of fire setting applies to the 2nd – 12th fire
modes. The max rate of fire is adjustable from 10 to 25 balls per second, and has an
unlimited setting for maxing out the loader system. The default is 7, which is roughly
13 balls per second. Oscillator inconsistencies from chip to chip make it impossible to
time perfectly, so the only true way to check rate of fire is to use a Pact Timer or
ballistic chronograph. The red radar chronographs commonly found at fields are NOT
reliable.
