Each pot has 3 connections. The ends of the pot are connected to ground and 5v as shown in the picture below. So this means "daisy chaining" all of the pot end connections on the counter-clockwise end to ground and all of the pot end connections on the clockwise side to 5 volts. Ground and 5 volts are supplied by the included wiring harness.
Then, each pot center (slider) connection is connected to one of 6 wires on the harness.

The picture shows an example of two pots connected, to the X and Y axes.

BLACK	GROUND
RED	5 VOLTS
BLUE	X AXIS
ORANGE	Y AXIS
YELLOW	Z AXIS
GREEN	X ROTATION
GREY	Y ROTATION
PURPLE	Z ROTATION
BROWN	NOT USED

If you are using controls which don't cover the entire range of travel of the pot, you will need to calibrate the control. Click on "Control Panel", "Game devices", and then highlight the entry for "A-PAC Interface", and follow the instructions. This will ensure that a full movement of the control device corresponds to a full movement in the game. Where the instuctions state "press a button" you can click on "next" instead.

"Trick" Calibration.
You might want to calibrate so that an analog control produces full movement in the game over a small movement of the control. You can easily do this. During the calibration process, when it asks you to move the control to the limits of movement, if you only move it to, for example 50% of the travel, this will be logged as the full-travel position, so you will get a full game movement over 50% of the actual control motion.

Other Settings
MAME has a setting for "Joystick Dead Zone". This is useful when you are using an analog control in a digital game, as you can tweak the "travel" of the control, ie how far you have to move it before it registers as an emulated switch press.

Using with MAME

To use this device with MAME, all you need to do is enable joystick support in MAME.INI. You will need to go into the MAME control menu (press TAB while in a game) and assign each axis to the appropriate control.
