show the current power level of your battery with a flickering red, yellow, or green LED. After, it will show a solid or blinking blue LED (unless changed from the default). To turn off, press and hold the power button for 1.5 seconds, until the LED turns off, then release. Every time the marker is turned on, the eyes are enabled. The marker can be turned off regardless of the state of the eyes.

The eyes are enabled when the marker is first turned on. The eyes can be toggled by quickly pressing and releasing the power button. The LED will change colors to indicate the mode change.
Features
The Musashi 8 Marq board supports the 4C™ system, and will automatically detect whether a single eye set or dual eye set is installed at start up.
Musashi 8 Board Instructions • • • • • •
Fully functional in the Bob Long Onyx/Marq series of markers Based on the Musashi 8 software, with full support for the 4C™ eye system Both a plug-and-play wiring harness socket and board mounting point for the Draxxus Pulse RF transmitter are standard New model microcontroller runs at 8 Mhz for no hardware lag and the fastest code execution Enhanced power switching hardware for the solenoid Includes 12 fire modes: uncapped semi-auto, capped semi-auto, PSP autoresponse, PSP 50% ramping, PSP 100% ramping, PSP burst, NXL fullautomatic, auto-response, 50% ramping, 100% ramping, 3 round burst, and full-automatic Asynchronously monitors the trigger switch, using an interrupt based scan at 2 million times per second Gangster setting allows 3 different options for every fire mode, giving 36 different “breakout” style modes Adjustable ABS programming prevents first shot drop-off AMB (anti-mechanical bounce) and CPF (cycle percentage filter) algorithms help to eliminate mechanical bounce and switch bounce Power efficient software and hardware lengthens battery life Programming mode allows changes to debounce, dwell, loader delay, AMB, ABS dwell, fire mode, fire mode max rate of fire, eye mode, CPF, ramp start, gangster mode, bolt delay, and training mode dwell All settings are stored in non-volatile memory so they are not lost when battery is disconnected One-touch startup enables the marker to fire instantly Automatic 15-minute idle power down saves batteries 4 eye modes: delayed, forced with force shot, test mode with rate of fire indicator, and reduced dwell training mode with rate of fire indicator Low battery indicator hardware and software shows battery level each time the marker is turned on
Installation Removal and installation of the board in a Marq must be carefully done to ensure the electronics are not damaged. Begin by removing the grips from the marker. This will expose the entire circuit board. Remove the main wiring harness, the three mounting screws from the board, and then the board itself. Be aware of the trigger switch return spring mounting bracket which sits over the trigger switch. Place the return spring mounting bracket over the M8 Marq board’s trigger switch, then insert the board into the grip frame top first, making sure the wiring does not get pinched. Replace the 3 mounting screws. Plug in all the connections. It may be easier to completely remove the grip frame from the marker to replace the trigger return spring so you can insert it from the top. If the marker does not turn on, it may be due to a low or incorrectly inserted battery.
LED Indicator The multi-color LED that shines out the rear of the grip frame shows which mode of operation the marker is currently in: Rapid Blinking Red Rapid Blinking Yellow Rapid Blinking Green Solid Teal Solid Blue Solid Purple Slow Blinking Blue Slow Blinking Yellow Slow Blinking Red
At startup this indicates an exhausted battery At startup this indicates a low battery At start this indicates a good battery Both eyes are blocked Top eye is blocked Bottom eye is blocked No ball in breech Eye malfunction, max rate of fire reduced to 12 bps; clean eyes or make sure the gun is fired with paint and air Eyes disabled, rate of fire limited to 20 balls per second in mode 1; otherwise capped at fire mode max rate of fire for fire modes 2 through 12.
Power Operation Pressing and releasing the power button turns the marker on. The battery indicator will
If using a single eye set the LED indicator works as follows: Slow Blinking Blue Empty breech Solid Purple Ball in breech, ready to fire With a dual eye set the LED indicator works as follows: Slow Blinking Blue Empty breech, both top and bottom eyes unblocked Solid Blue Top eye set is blocked Solid Purple Bottom eye set is blocked Solid Teal Both top and bottom eye sets blocked The use of the 4C™ eye system allows for much faster rates of fire because it can anticipate the next paintball being loaded into the breech and start the firing cycle early, which negates the delay time found in the pneumatics of the paintball marker. The Musashi 8 software was written specifically to take advantage of this arrangement, and automatically uses the top eye set when the loader is feeding fast enough. It can also determine when the top eye set is blocked by paint or debris, and will default to using only the bottom eye until the top is clear again. Once the top eye is clear, it will resume use of both eye sets. 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. If the eye system is continually blocked (e.g. putting your finger in front of the eyes) and is unable to see the bolt return after every shot, the max rate of fire will be reduced to about 12 balls per second to prevent further chopping, and the LEDs will blink yellow to indicate the eye malfunction. Firing the marker with paint and air will utilize the eye system correctly, maximizing the rate of fire. When the eyes are off, the rate of…
