Cygnus Editor Operating Manual
The AutoDetect check box (see Figure 2-9 ) specifies that the software should
periodically check the communication port for controllers and automatically bring
them online.
The other four boxes can be set to further improve the timing of the
communications. Specify the maximum number of controllers expected and the
frequency with which the Cygnus Editor will check to achieve optimum
communications performance.
The interval specified (Check for a Controller every “t” seconds) is the time
between successive checks.
Once the maximum number of controllers is found, the Cygnus Editor discontinues
searching. If the Check for at most “n” Controllers value is set to the actual
number of controllers, it can save significant overhead by not looking for controllers
that don’t exist. Specifying the maximum address (Max Controller address) for
the port can significantly reduce overhead, also.
NOTE: The Max Controller Address is the largest address of any Cygnus Thin
Film Controller connected to this port. If this value is set too high it could
take a long time for the Cygnus Editor to detect a new controller coming
online. However, if the Max Controller Address is set too low then
controllers with addresses larger than this value will not be detected.
For the least amount of communications overhead (i.e. the fastest
communications) set the Cygnus Controller addresses from 1 to the maximum
number in consecutive order. For example, for six controllers, set the addresses to
1,2,3,4,5 and 6, set the "Check for at most" parameter to 6 and set the Max
Controller address to 6.
When Autodetect changes are finished, click OK to accept the settings (or Cancel
to abort the action). If AutoDetect was selected, the program will automatically
detect and bring online any controllers connected to the ports. A short delay may
occur while bringing the controllers online.
