6.  Reboot your computer. 
7.  Restart the WinX application and begin acquiring data or focusing. If you see the 

message again, increase the DMA buffer size. 

The ST-133 Controller has three plug-in slots. The Analog/Control module (leftmost slot 

when the controller is viewed from the rear) and the Interface Control module (either a 

TAXI or a USB 2.0 compatible module in the middle slot) are always provided. The third 

slot, however, is covered with a blank panel unless a PTG module has been installed in 

the ST-133.   
If a module is ever removed for any reason, internal settings should not be disturbed. 

Changing a setting could radically alter the controller’s performance. Restoring normal 

operation again without proper equipment and guidance would be very difficult, and it 

might be necessary to return the unit to the factory for recalibration.  
Note: If you have an installed PTG and are changing from one interface type to another 

(TAXI to USB 2.0 or USB 2.0 to TAXI), contact Customer Support for specific 

changeover instructions. See page 108 for contact information. 

1.  Always turn the Controller OFF before removing or installing a module. If a 

module is removed or installed when the controller is powered, permanent 

equipment damage could occur which would not be covered by the warranty.  

2.  Before handling any boards, take precautions to prevent electrostatic discharge 

(ESD). The modules are susceptible to ESD damage. Damage caused by 

improper handling is not covered by the Warranty.
