BCX Series Operating Manual
2. Computer
In most cases, ATLAS installs an IBM PC-compatible notebook computer on the
cabinet. Most of the cabinet functions can be actuated using the computer mouse. On
notebook computers, the mouse is usually replaced by a “glide point” (Compaq
Armada), “track ball” or “track point” (IBM Thinkpad). If the user is not accustomed
to these devices, practice will be required. In this manual, all of these different
pointing devices will be referred to as the “MOUSE.”
The computer will include a color screen and keyboard. Some cabinet functions must
be operated by use of the keyboard. Communication to the cabinet I/O block is
accomplished by use of a standard serial cable attached to the computer’s 9-pin RS232
port.
This cable must be attached at all times.
3. Computer Security and Protection
If the cabinet includes a notebook computer there is a locking mechanism to keep it
secure. The sliding acrylic door on the control top panel has a push lock on the
uppermost edge of the door. Turn the key 360 degrees and the lock pin will eject.
Now the door can be pushed up. When the cabinet is in operation it is necessary to
keep this door closed to protect the computer from possible contaminants in the lab
air.
4. Computer Performance
Many factors affect the performance of the computer during the control of the BCX.
It is important to avoid as many factors that will slow down the performance since the
main function of the computer is to control the cabinet. Avoid loading other software
on the computer as this will slow it down. Be careful of network traffic to the
computer if it is connected to a LAN.
It is very important to reboot the computer on a regular basis, but not less that every
other week. Re booting the computer clears out the RAM memory and any other
potential file problems that could cause the CPU to ‘lock-up” and stop controlling the
cabinet. This is a part of regular maintenance. This is very important where the
datalogging frequency of the control software is high, as it creates a very large data
file.
