Removing/Installing A Plug-In Module; Figure 50. Module Installation - Princeton Instruments MicroMAX System User Manual

Chapter 10
bus arbitration scheme assures that, as long as every PCI card conforms to the PCI
guidelines, the on-board memory will never overflow.
Unfortunately, there are some PCI peripheral cards that do not fully conform to the PCI
guidelines and that take control of the bus for longer periods than the PCI specification
allows. Certain video cards (particularly those that use the S3 video chip) are notorious
in this respect. Usually you will be able to recognize when memory overflow occurs
because the displayed video will assume a split-screen appearance and/or the message
Hardware Conflict will be displayed (WinView/32). At the same time, the LED on the
upper edge of the PCI Serial card will light.
Users are thus advised not to take any actions that would worsen the possibility of
memory overflow occurring when taking data. In that regard, avoid multitasking while
taking data. Specific operations to avoid include multitasking (pressing ALT TAB or
ALT ESC to start another program), or running a screensaver program.

Removing/Installing a Plug-In Module

The ST-133A 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
(middle slot) are always provided. The third slot, however, is always covered with a
blank panel.
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.
WARNING
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.
