This is the operations and programming manual for the drop-in version of the Predator boards made for the Shocker and the Nerve, version 5.0 (released in June 2005). If you have the custom-installed version in your marker, the registers and settings will be different (check the Manuals & Documentation page for a more complete list).

Note: This is only a guide for HOW to adjust the board. Information regarding WHERE to set adjustments at can be found on the Setting Electronics and Pressure mainpage.

Upgrading: This is the most current version programming available.

Original manual: Predator SFT 5.0

Board Operation:
To turn on the marker, press and hold the power button for one second. The LED behind the button will light, and the LEDs on the surface of the board will also begin to pulse (if you have clear grips then you will be able to see them, if not then nevermind). At this point the marker is active, ready to fire, and the eyes are on. There is no forced shot; the board automatically knows the difference between a ball being loaded and a ball not being loaded.

As said, the eyes are enabled when the marker is first activated. You can toggle between eyes on and off by pressing the power button at any time. The eyes will then be disabled and the board will be capped at whatever you set the max ROF at in register 11 (if present). When no ball has loaded (or no ball is detected), you can force a shot by holding the trigger for 3/4 of a second. While the eyes are active, the maximum rate of fire will be set to whatever you have it at in register 2.

The board tracks the movement of the bolt from shot to shot and uses this informaiton to optimize the firing cycle and tell if there's an eye problem or not. Therefore, if you aren't actually cycling the bolt with paint and air while the eyes are active, the ROF will be put into fault mode and the max speed will be capped. The board will fire much faster when there is paint and air present.

Solid LED: Ball loaded, marker ready to fire
Slow-blinking LED: No ball loaded
Fast-blinking LED: Eyes off

DIP Switch Settings:
The DIP switchbank on the surface of the board controls the tournament lock and eye sensitivity...

Predator SFT

DIP switch "1" is the eye sensitivity control for the board. leave this switch in the off position.
DIP switch "2" is the tournament lock toggle for the programming mode. Turning it on will disable all trigger programming. When the lock is on, the board will be set to the last settings and you won't be able to adjust them until it is turned off.

Programming:
All settings are stored electronically. To adjust the programming, the tournament lock DIP switch (switch 2) must be off
1. To enter the programming mode, turn the board on as normal (hold the power button for one section) while holding down the trigger. The LED will blink once then turn dim.
2. At this point you are expected to select a register. A register is simply one of the board's adjustment settings. To select a register, click the trigger the appropriate number of times corresponding to the register you want to adjust (listed below).
3. Once you have selected a register, the LED will blink a certain number of times to tell you what the current setting is set to.
Note: if you accidentially selected the wrong register, simply turn the board off then back on again to continue programming.
4. Once the LED stops blinking, click the trigger to input the new amount for that setting.
5. Once you have entered the new amount, wait one second and the board will store the new setting then blink the LED twice.
6. After the new setting has been stored, you return to the "main menu" where you can select another register to adjust. If adjusting register 1 (firing mode), after you select the new mode the marker will exit the programming mode and the gun will then be ready to fire.
You can turn the board off at any time by holding the power button.

Fire modes:
1. Semiauto: Semiautomatic firing.
2. Autoresponse: Fires on the pull and release of each trigger pull.
4. Smooth ramping: Once the ramp activation is reached, the trigger debounce will drop and allow a small amount of trigger bounce to occur, which will increase your fire rate a few BPS.
5. Assisted ramping: Once the ramp activation is reached, the marker will assist your fire rate by adding shots as you fire. This is similar to "turbo mode" where the marker fires three shots for every two trigger pulls.
6. hard ramping: Once the ramp activation is reached, the marker will instantly increase the fire rate to the mROF setting.
7. Triplet shot ramping: The marker fires three shots for every trigger pull, the speed of these shots increases as you pull the trigger faster.
8. PSP 1-2-3 shot smooth ramping: Automatically selects 1-2-3 shot semiauto then smooth ramping (ignores registers 5 & 6).
9. PSP 1-2-3 shot hard ramping: Automatically selects 1-2-3 shot semiauto then hard ramping (ignores registers 5 & 6).
10. PSP 1-2-3 shot triplet shot ramping: Automatically selects 1-2-3 shot semiauto then triplet shot ramping (ignores registers 5 & 6).
11. NXL 1-2-3 shot fullyauto: Automatically selects 1-2-3 shot semiauto then fullyauto if the trigger is compressed for the fourth shot (ignores registers 5 & 6).
12. Breakout mode: The first shot will be fullyauto as long as the trigger is held down, all other shots follow the same as hard ramping mode.
13. OMFG mode: Marker fires at the mROF for one second once the ramp activation is reached.

Timing registers:
Fire mode (register 1): 13 firing modes available. After a mdoe is selected, the board will exit programming mode and you'll be ready to fire.
Maximum ROF (register 2): Max ROF in balls-per-second.
Debounce setting (register 3): Please note that this isn't in full millisecond intervals; it's closer to 1/3-ms intervals.
Dwell (register 4): Amount of time that the solenoid will remain open, that the bolt will remain forward.
Ramp activation speed (register 5): Activation speed in balls-per-second that you must reach to activate a ramping mode.
Ramp activation shot count (register 6): Number of semiauto shots that you must fire at the ramp activation speed before the ramping mode wll activate.
Fire holdoff time (register 7): This is the amount of time after the eye senses the bolt open that it will allow the marker to fire again, adjusted in milliseconds.
Eye holdoff time (register 8): Delay between the ball being detected and when the board will allow the marker to fire, adjusted in milliseconds.
ABS activation time (register 9): Amount of time after the last shot that the ABS will engage to add milliseconds to the dwell for the next first shot.
ABS dwell time (register 10): Amount of dwell time that will be added to the normal dwell setting for the first shot when register 8 is enabled.
Eyes off ROF (register 11): Max speed wheil the eyes are diabled. This is also how fast the board will fire if the eyes are in fault mode.
ROF increment (register 12): This register is used to fine-tune your ROF settings by including fractions of a second to the max speed. For example, if you set the mROF to 15-bps, register 12 to 0.4 seconds, it will make the mROF 14.4-bps.
Disable eyes using trigger (register 13): If this is set on (1), the eyes will toggle on or off if you hold the trigger down for one second. If this is set off, the eyes won't toggle on or off regardless of how long you hold the trigger. Eyes can be toggled using the power button at any time, regardless of what this is set to.
Force shot using trigger (register 14): If this is set on, the marker will fire after 3/4 second if you hold the trigger down and no ball has loaded. This is used to clear the chamber in case a ball rolls forward and prevents the next one from being detected. If this is set off, there won't be any forced shots regardless of how long you hold the trigger.
Eye sense (register 15): For the stock eye, set this register between 2 and 20 to determine the eye sensitivity amount. A setting of "2" is the least sensitive while "20" is the most sensitive. A high sensitivity will be needed for darker or more rough paintshells. This setting is also used to calibrate the eyes to your specific gun, since every Vision eye is positioned differently (the setting may work on one gun but not another using the same paint).
If the marker fires with no paint loaded, chances are the eye is detecting the eye hole. For this you should decrease the sensitivity setting.
If you have beam-break eyes installed, this must be set to "beam-break".

This is a video I made of an example of programming. In this video I increase the dwell by three milliseconds, then select semiauto.
