Voltage Conversion
Connector Pin-out
If you need to convert your game to a different supply voltage than it was wired
for at the factory, locate the 9-pin connector at the input of the transformer, in
the bottom of the lower cabinet (shown opposite and in the green box on page
D-115).
Power the game down and disconnect the 9-pin connector (it has locking tabs
on each side). Looking at the back of the jumpered connector (the end with the
wires protruding), locate the pin 1 “rib” indicator and orient the connector so
that it is in the upper right hand corner, as shown opposite. The red numbers
show pin numbers for the entire connector.
Look at the illustration for the desired configuration and compare it to the
current configuration. Using a 0.084” pin extractor, remove all pins that re-
quire repositioning by pushing them out of the back of the connector, from the
front. You can reuse existing wires as long as they were not damaged during the
removal process. Fashion new, short jumper wires, as needed.
Using the appropriate illustration for reference, insert the jumper pins all the
way into the connector, in the proper positions, from the back side, until they
lock in place.
For a 120V supply voltage, connect the AC inputs across pins 1 & 7. Next, jump-
er pins 2 & 3 together with a short piece of black wire. Lastly, jumper pins 8 & 9
together with a short piece of orange wire.
For a 220V supply voltage, connect the AC inputs across pins 1 & 4. Then jump-
er pins 3 & 9 together with a short piece of black wire.
Note:
Your Dialed In game makes use of switching, modular power supplies for the
RGB LED & GI lighting systems (4V and 7.5V), the sound amplifier board (24V), the
CPU board (5V & 12V ATX supply) and/or other game functions. These switching
power supplies have voltage selection slide switches on their exterior panels that
must be in the proper position (120V or 220V) before applying power to the game.
