Software
Game Operation
The LAX Jr. controller operates in (4) different states.
1. “RETURN ARM” - This is the state the machine enters upon power up. It runs the motor until the arm switch
opens. Once the arm switch opens, the arm motor i s shut off, and control is transferred to “GAME WAIT”. If the
arm is being returned by the “GAME PLAY” state, a motor decel sound is played.
2. “GAME WAIT” - In this state, the machine waits for a credit(s). Upon receiving a credit, the controller enters
th e “GAME PLAY” state. If this is the first credit inserted, a horn sound is played followed by a car starting
sound. NOTE: Credits can be received during all states!
3. “GAME PLAY” - The prize gate is opened, Play button lamp is turned on, and the player controls operation of
the arm until the arm switch closes. During the player control portion of the game, appropriate motor sounds
are played in conjunction with the play button being pressed. Once the arm switch closes, the prize motor runs
the allotted time, and the controller enters the “RETURN ARM” state. When the arm is returned home, the
prize gate is closed and the sound is shut off.
4. “TILT” - This state can only be entered by the closing of the tilt contacts, but can be entered at any time.
During the duration of this state, the prize gate is closed, play lamp & coin door lamps are turned off, and a
siren sound is played at an elevated level. The controller remains in this state for the programmed time, then
returns at where it left off.

Diagnosti cs & Configuration
To enter the Diagnostic & Configuration state of the controller, press the small button mounted on the PCB
labeled “SWDIAG_1”. NOTE: In software version 1.0, you can press an external push button label “DIAG”. After
pressing this butt on, the first configuration item is displayed. If configuration item #2 is set to “0”(Text), you will see
“GAmE CounTEr”. If Item #2 is set to “1”(Hex) you will see “ - 1”.
Use the appropriate “SWDIAG_1/DIAG” button to advance through the item #’s. To change the value of an
item, once the proper item has been selected, press the play button. Pressing the play button the first time
displays the current value(Firmware version 1.0d or later). Pressing the play button increases the value of the
current item #. If the value exceeds the range of the current item, it rolls over and starts with the minimum value of
the range.
