1.3 Applications
The 960CD-220 series Controller Modules are compatible with both the 960MB Motherboard and the
961MB Motherboard bus structure. There is total compatibility with all of the 960 data acquisition and
input/output modules. The actual operations performed by the specific controller module are dependent
more on the firmware employed than with the hardware utilized. Refer to the operation section of the
system manual for a total description of the 960 monitor's operation and the types of communications
provided for the specific application.
Module functions and applications are discussed in the following paragraphs. Table 1-1 compares the
960CD Modules. Table 1-2 lists communications loop connections to a minicomputer or safety related
display. Table 1-3 lists communications loop connections. Figure 1-2 illustrates standard minicomputer
communications. Figure 1-3 illustrates fiber optically isolated minicomputer communications with a control
room safety-related display. Figure 1-4 illustrates safety related display communications. Figure 1-5
illustrates an RS-232 interface to a Victoreen 977 Series Preamplifier/Electrometer. Figure 1-6 illustrates
safety related communications with an RS-232 Interface to a Victoreen 977 Series
Preamplifier/Electrometer.
