Warning!!!

Do not install an Ion 2007 or 2007.5 hard drive into a Force game, there is a strong chance of corrupting the firmware on the

SMT-4 (black) controller and leaving the controller inoperative with “Touch controller not found”.

Serial port based controllers:

SMT4: Force platform; SMT3: Maxx Platform; SMT2: XL Platform.

Symptom: No green LED or green LED is dim and not responding to touch.

Warning!!!

Do not install or replace the touch controller. There is a strong possibility of damaging the replacement controller.

Procedure: With game turned off, start by checking the resistance across connector points 4 & 5. If the resistance measures

from 0 to 180 ohms (could possibly be higher) then the touchscreen cable is defective and the controller damaged. At this

point, the touchscreen and controller will both need to be replaced. There should about 2 to 3 MB ohms across connector

points 4 & 5. Should the resistance measure good across connector points 4 & 5, then only the touchscreen controller will

need to be replaced. Refer to the diagram for the connector points.

Attention: This procedure will not apply to USB controllers in Ion games.

TOUCHSCREEN OVERLAY CONNECTOR

CRT Monitors:

(Force Classic 13” CRT, Radion 15” CRT, and Upright 19” CRT)

• The touchscreen cable should not be positioned under or on top of the yoke of the monitor.

• The touchscreen controller cable should not be positioned near the flyback transformer.

TechTip: If the cable is not properly installed, the touchscreen response will be 180 degrees out of sync.
