System Relevant Information
The following system relevant information is general in nature but should still be considered
when developing applications using the CP381.
1.4.1
System Configuration
When implementing applications, precautions must be taken to ensure that the input signals
presented to the CP381 comply with the specifications set forth in this manual. For this reason
it will be necessary for most applications to provide signal conditioning prior to presenting the
digital inputs to the CP381. In addition, it is imperative that signal interference be kept to a min-
imum. Please refer to chapters 4 and 5 for further information.
1.4.2
Driver Software
The CP381 is supplied with appropriate driver software which provides software interfacing
with the system master.

SUBJECT
INFORMATION
System Configuration
The CP381 operates with a system clock frequency of 33 MHz.
The number of CP381’s which can be installed in any one system depends
solely on the number of CPCI slots available.
Master/Slave Functionality
The CP381 functions only as a slave. As such it requires a system master for
servicing.
System Controller
The CP381 cannot function as a system controller.
Digital Inputs
Digital inputs to the CP381 must be conform to the inputs specifications set
forth in this manual for the CP381. In most cases, some form of signal condi-
tioning will be required on the process side prior to a signal being presented
to the CP381.
