Cygnus 2 Operating Manual
2.3.2.1 Source Control Connection
Six Digital-to-Analog (DAC) outputs are provided as standard equipment with the
Cygnus 2. These standard 6 DAC channels with BNC connectors and six optional
DAC outputs on a 15 pin sub-D connector may be programmed for Source control
or chart recorder functions as desired.
2.3.2.2 Crucible Indexer Connections
Example: 4 pocket crucible using outputs 6 and 7
Number of crucibles = 4
Crucible output = 6
For this example, wiring to the controller is based on Table 2-1 . Only relays 6 and
7 are needed to encode the four possible positions.
2.3.2.3 DAC Option Kit
An optional Digital-to-Analog Converter (DAC) card can be installed into the
Cygnus 2. This card provides six additional DAC outputs, numbered 7 through 12,
for Thickness and/or Rate as determined by the DAC Output Option parameters.
The pin assignments for DAC outputs 7 through 12 are shown in
Table 2-2 .
