When installing the joystick to the panel, the pillar can be fixed in several ways, for example:
• Female mounting using an extra 5mm screw (not supplied)
• Female mounting using one of the joystick-panel mounting screws
• Male mounting into one insert of the Ultimarc joystick mounting kit
• Male mounting into a different faceplate hole from the mounting using 5mm nut (not supplied)
The mounting plate may need to be bent slightly downwards so it always is engaged with the pillar. Secure USB cable using the 2 holes in the PCB and cable ties, to avoid flex on the USB connector.
Setup is done using the WinIPAC program which can be downloaded from
Note: If you also have an I-PAC board connected this will need to be unplugged temporarily for the program to recognise the 12-way board.
The program allows setting of the clockwise and anti-clockwise clicks to any keyboard key or game controller button. On the Config tab, there is a setting for “Switch Debounce”. This can be set to one of 4 settings. On this interface, this controls the length of the key “pulse” issued on each click. Some slower applications may require a longer pulse.
