Blackheart boards programmed in August 2006 and later are flashed with this style programming. The difference between NXT and older boards is that the older boards don't have support for the Shocker NXT eye system.

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

Upgrading: This is the current version of the board. no upgrades available.

Board Operation:
To activate the board, push and hold the power button until you hear it chirp (it will activate after approximately one half second). The board is activated in Vision mode, ready to fire. To deactivate the board, hold the power button in until the board chirps once more and the LED no longer blinks (this will occur after two seconds).

The LED in non-Vision mode blinks twice fast every one second (the interval between blinks is 1/4 of a second). The LED in Vision mode while a ball is loaded is four blinks every second. If no ball is loaded, the LED will blink once every second. As said, to toggle between Vision enabled and disabled, push the power switch once.

Programming:
There are several adjustment modes available. To adjust any of these, you must first remove the left side of the grip panels so that you can have access to the lower, vertical circuit board. You will see two grey buttons located on the side of the board; these are the programming buttons and are used to adjust the settings. There are two additional LEDs located on the side of the board as well (yellow and red).

Programming buttons/LEDs

When you enter programming mode, one of the LEDs will light up, signifying you're in programming mode. Pushing the programming button will cycle through the nine adjustment modes, each with its own LED color/pattern:
Solid yellow - dwell
Solid red - recharge
Single blink yellow - Firing mode
Single blink red - Debounce
Double blink yellow - ABS dwell
Double blink red - Ramp activation speed
Fast blink yellow - Ramp sustaining speed
Fast blink red - Ramp activation shot count
Long blink yellow - Eye sense

Steps for adjusting the board:
· First, select which adjustment mode you want by the LED pattern and color. For example, select solid yellow to change dwell, single blink red to adjust debounce, etc.
· Once you've selected which setting you wish to adjust, pull and hold the trigger. After three(3) seconds, the board will chirp five(5) times, denoting you can now adjust the setting.
· Don't release the trigger; keep holding it down. You can now use the top and bottom programming buttons to adjust the setting up and down as much as you wish. The top button increases the setting whereas the bottom button decreases it.
· The board will chirp each time you adjust the setting one interval. When increasing the setting, the board will chirp a high-pitch tone. When decreasing the setting, the board will chirp a low-pitch tone. The LEDs will also blink to signify this.
· At some point you will reach the maximum or minimum setting, denoted by a rapid chirping tone. This means you can no longer adjust the setting in that direction.
· Once you've arrived at the new setting for the adjustment, release the trigger to return to the programming mode. You can now select another setting to adjust, if needed.
· To exit programming mode, pull the trigger once. After pulling the trigger, turn the board off to save the settings. If you pull the battery, the adjustments you made will be lost, and the setting(s) will revert back to whatever they was last set to.
· Example: if you want to adjust your dwell, select solid yellow then told the trigger. Once the board chirps five times, you can increase or decrease using the power/programming buttons. For example, to increase the setting by four, push the power button four times. Once you've adjusted the setting, release the trigger. To save and exit, pull the trigger and turn the board off.

If you wish to know what the current setting is, select the adjustment and don't press anything for four(4) seconds. The board will chirp back to you the current setting.

Shortcut key: If you wish to revert the setting to whatever you had it last set to, push the power and programming buttons both for one(1) second. The board will chirp and the programming LEDs will light up to signify your adjustment has been reverted.
For example, if you have your dwell set to 15, then a few days later you increase it to 20, you can then use the shortcut key to revert the setting back to 15.

Dwell: solid yellow
Dwell is the amount of time the solenoid remains on, which is the amount of time the bolt will remain forward.
· Dwell is required to allow the bolt to fully cycle and give the marker enough time to fire the ball.
· If you set dwell too low you will have velocity problems (dropoff, won't be able to achieve a certain velocity, etc).
· If you set dwell too high, you'll waste air each time you fire and get slightly less shots per tank.
· For information on recommended dwell settings, go back to the electronics and pressure page.

Tech Dwell is adjustable 3 and 19 milliseconds, in 0.25 millisecond increments (64 settings total). Information for "where to set dwell to" is often given in chirps and NOT milliseconds. For purposes of upgrading the board to another one (which uses milliseconds to adjust), you may need to know how many milliseconds the dwell setting was for the Nerve board.

How long is my dwell time, in milliseconds, if I have it set to blinks from the bottom?

Recharge: solid red
Recharge is the name for the amount of time the board waits between each shot. This is used to determine the rate of fire (ROF).
· When you increase recharge, you increase the time between each shot, which lowers your rate of fire. And vice-versa.
So, if you want to increase your rate of fire, you want to decrease recharge. If you want to decrease your rate of fire, increase recharge.

Tech Recharge is adjustable between 15 and 70 milliseconds in one-millisecond intervals (55 settings total). The recharge time is then added to your dwell setting to determine how fast your marker will fire. The minimum speed is roughly 11-bps, whereas the fastest speed is 20-bps.
For demonstration, a diagram of the firing cycle with adjustments can be seen here...
Firing cycle diagram
This diagram shows that when you increase your dwell setting, the recharge will stay the same, thus the ROF will be lower since the firing cycle takes longer. To compensate you need to then lower the recharge. This is an example and uses example numbers.

If you wish your marker to fire the maximum speed, simply set the recharge setting to 0 chirps. If you wish to cap the marker's rate of fire at a lower speed, you can use this chart below to find your recharge setting. To use this chart, match up your current dwell setting (left column) with your desired BPS cap (top row) and the corresponding number in the table will be your recharge setting in chirps.
The chart starts at 11.5-bps because that's the minimum speed for most dwell amounts. The chart only goes up to 17-bps because there isn't much point to "capping" the gun at anything faster than 17-bps, since that's already extremely fast and you won't be able to audibly tell the difference between exact speeds at that point.

Tech If you wish to know the formula used to create the above chart, here it is:
(DwellChirps/4) + 18 - (1000/DesiredROF)
or DwellMilliseconds + 15 - (1000/DesiredROF)
...This will give you a negative number. Ignore the negative sign and round the number up, and that will be your recharge setting. Example: If you want to cap it at 15-bps and your dwell is set to 40, the formula will look like this:
13 + 15 - (1000/15)
(40/4) + 18 - (1000/15)
This will give you -38.6667. Ignore the negative and round it up, and you have 39.

Firing Mode: Single blink yellow
Blackheart is equipped with four firing modes, in this order from highest to lowest:
4. PSP rebound - First three shots are semiauto, but after the third shot the marker will fire in rebound ramping mode. One second reset.
3. NXL fullyautomatic - First three shots are semiauto, but if you hold the trigger down for the fourth shot the marker will fire fullyauto at the max ROF. One second reset.
2. Rebound ramping - Assisted firing mode (ramping). Increases your ROF to the maximum speed once you hit the ramp enabling speed and shot count (below).
1. Semiautomatic - One shot per one pull semiautomatic firing. No ramping.

Debounce: single blink red
Debounce is the amount of time after the marker fires that it will accept new trigger pulls, adjusted in milliseconds (1-25 in 1-ms intervals).

ABS dwell: double blink yellow
ABS stands for anti-bolt stick, and is also known as "BSA" (bolt stick adjustment). This is the amount of dwell that will be added to the first shot after the board doesn't fire for a givin period of time. If your ion is experiencing bolt stick and the velocity of the first shot is less than the rest of your shots, then anti-bolt stick settings can be used to increase the dwell for the first shot so there is no drop. However, if you set anti-bolt stick too high, the first shot will fire at higher velocity and be illegal.

Ramp activation speed: double blink red
This is the speed that you must fire in order to engage your firing modes.
· Adjusted between 1 and 10-bps.
· Effects all firing modes except semiauto.

Ramp sustaining speed: fast blink yellow
This is the speed that you must keep firing in order to maintain ramping. If you fire less than this speed, the board will stop ramping just as if you pulled the trigger too slow.
· Adjusted between 1 and 10-bps.
· Effects rebound and PSP rebound firing modes.

Ramp activation shot count: fast blink red
For NXL fullyauto and PSP rebound firing modes, this is the number of times you have to pull the trigger before the firing mode will act. For instance, if you want three semiauto shots before fullyauto (this complies with NXL rules) then you would set this to 3. If you want four shots before fullyauto then set it to 4.
· Adjustable between 1 and 10 pulls.

Eye sense: long blink yellow
This is the eye setting which is required for the Shocker or Nerve to use, to operate the eye in the marker.
Setting 1: Shocker SFT reflective eye, or Shocker NXT with reflective eye installed.
Setting 2: Nerve
Setting 3: Shocker NXT (beam-break eyes)

Demonstrational Videos:
This is a video I made of an example of the programming. In this video I set the dwell setting to 25 chirps.
