You should be able to power on at this point. For a quick test of the kit, you can use the jumper settings. The J20 jumper header is the 16-pin dual-row connector, located just to the left of the U1 main chip. For normal operations, the AFM Expansion kit runs with no jumpers installed.

Test Jumper Settings
    Jumper #1: Diagnostics Mode
    Jumper #2: Super Jets Test Mode
    Jumper #1 & 2: Input Test Mode

Diagnostics Mode

Set a jumper horizontally, connecting the top two pins from the first row of the header. This test cycles through the backbox GI, the Jet Bumper GI, the "Super Jets" Flasher, the Attack Hallway LEDs and the AFM-LED mini-saucer enable/disable signal. The entire test takes about two minutes to run a full cycle.

Remove the jumper(s) at anytime to end the diagnostics routine(s).

For proper testing, please be sure the coin door is closed or the "Super Jets" flasher will not activate.

Super Jets Test Mode

Set a jumper horizontally, connecting the two pins from the second row of the J20 header. This turns on the "Super Jets" feature all the time. The Jet Bumper GI will run the cycling animation, and any jet bumper hit will trigger the flasher. You can use this mode to verify that each bumper properly triggers the flasher. If not, you may need to re-orient the sensor below the Jet Bumper Coil Assembly.

Signal Input Test Mode

Set Jumpers #1 and #2 to enter the Signal Input Test Mode. The LEDs on the left wall of the Attack Hallway will show you the status of the input signals being fed into the AFM Expansion board. The LED closest to the flippers is LED #1.
    LED #1: General Illumination (Yellow GI string) detected
    LED #2: Jet Bumper hit detected
    LED #3: Super Jets flasher detected
    LED #4: Strobe Light detected
    LED #5: Mothership LED Data detected
    LED #6: Mothership LED Clock detected (not used)
Note: This may be easier to view if you lower the target bank.

Testing Additional Functions

The "Attack Hallway" LEDs can be further tested during Attract Mode. These LEDs will run any time the Mothership LEDs are running and the Yellow GI is on. They may also run during Strobe Multiball, depending on the system jumper settings (see below).

The AFM-LED mini-saucer enable/disable feature turns off the mini-saucer LEDs from the original kit during Video Mode and Strobe Multiball. You can test this feature by going into the GI test, and making sure the Yellow GI string is off. Note that "dim" is not OFF. When the Yellow string is off and the Mothership LEDs are inactive, the mini-saucer LEDs should turn off.

The status of the AFM-LED mini-saucer enable/disable feature can be checked at any time via the LEDs on the AFM Expansion board. If the LED #3 is on, the mini-saucer LEDs should also be on. If LED #3 is off, then the mini-saucer LEDs should all be dark.

Configuration Jumper Settings
    Jumper #3: Enable Backglass GI "Blackout" Feature during Strobe Multiball and Video Mode
    Jumper #4: Disable the Hallway LEDs during Strobe Multiball
    Jumper #5: Super Jets Animation Setting (0 = Chase, 1 = Blink)
    Jumper #6: Hallway LED Animation Select (0 = Auto, 1 = Select)
    Jumper #7: Hallway LED Animation (Bit 0)
    Jumper #8: Hallway LED Animation (Bit 1)
Jumpers 6-8 operate together to allow the user to select a pattern for the Attack Hallway LEDs.

If Jumper #6 is not set, the Attack Hallway LED patterns are randomized.

If Jumper #6 is set, then the Attack Hallway LED pattern will follow the settings for Jumpers 7 & 8:
