• Extremely easy to use LED based menu system for changing settings

• All settings are stored in non-volatile memory so they are not lost when the battery is disconnected

• Five custom user profiles allow you to save settings for specific tournament series or performance tuning

• Additional features include adjustable debounce, anti-mechanical bounce, cycle percentage filter, anti-bolt

stick, ball in place delay, bolt delay, eye modes, ramp start, ramp percentage, breakout modes, and more

INSTALLATION

Installation of the Ebisu board must be carefully done to avoid damaging the electronics or wiring harnesses.

1. Remove one grip panel from the side of the frame, and unplug the battery.

2. Remove the two screws that attach the frame to the gun body.

3. Gently pull the frame and tray away from the gun body.

4. Remove the 2 nylon screws that secure the board inside the tray.

5. Gently pull the stock board out of the tray and unplug all the wiring harnesses.

6. Plug all the wiring harnesses into the appropriate sockets on the Ebisu board.

7. Insert the Ebisu board back into the tray and install the two nylon screws.

8. Tuck all the wiring harnesses inside the tray and gun body, and then reattach the frame/tray with the two

frame screws.

9. Replace the battery and grip panel.

BOARD OPERATION

Turn on the board by sliding the power switch to the on position.

Turn off the board by sliding the power switch to the off position.

The eye system is toggled on and off by pressing and holding the trigger for 3 seconds. The LED will reflect the eye

status as it changes.

The multicolor LED will display different colors based on which mode of operation the marker is in:

Flickering Red – at boot time indicates an exhausted battery.

Flickering Yellow – at boot time indicates a low battery.

Flickering Green – at boot time indicates a good battery. Solid Blue – eyes on, ball in breech, ready to fire. Slow Blinking Blue – eyes on, empty breech. Slow Blinking Red – eyes off. Slow Blinking Yellow – eye malfunction caused by the bolt not seen cycling. If used, the eye system cycles the marker as fast as possible. During each shot the eyes watch for the bolt to return, ending the current firing cycle and starting another as quickly as the pneumatics allow.

will blink green 5 times. Once the LED stops blinking, you have 2 seconds to begin entering the new setting. To enter the new setting, pull the trigger the desired number of times. For example, to set the debounce to 2, you must pull the trigger 2 times. Every time you pull the trigger the LED will light. After all settings have been changed turn the marker off using the power switch. Since some settings may have a very high value, it is not necessary to watch the entire blinking sequence.
PAGE 4
Bolt delay (default 5, range 1-15 ms, Viking only): A delay that gives the bolt enough time to block the eyes on the forward stroke. Too low will cause blank or skipped shots. Too high can slow down the marker. Eye mode (default forced, Viking only): 1. Forced with force shot – marker only fires when a paintball is present or a force shot is initiated by holding down the trigger for ½ second. 2. Delayed – the eyes will watch for a paintball for up to 500 ms after each pull, then fire.
PAGE 5
While in Excalibur mode the max rate of fire setting is used as a top end cap, but does not specifically force the rate of fire to be this value. This allows you to time the marker for optimal performance by using the various settings, and not have the max rate of fire setting override anything, which could create problems. For example, the default values are: Dwell 10, bolt open delay 2, bolt open time 40, bolt close delay 30 10 + 2 + 40 + 30 = 82 millisecond total cycle time, which is about 12 bps.
