The Poll for Instruments option queries the hardware interface to
establish communications with CANNON
® instruments attached to the
host computer.
Use the Poll for Instruments option to establish a computer connection
with instruments which may have come “on line” after the software has
been in operation. When the connection has been verified by the control-
ling software via the hardware interface, the instrument name will be
added to the status bar at the bottom of the VISCPRO
® window.
Security options
The VISCPRO ® application offers a level-based security system with a
log in procedure. This system ensures that available software functions
are appropriate for the security level of the user.
Initial security settings will be completed during CAV installation. Following
installation, security options may be accessed and changed from the
VISCPRO
® Main menu by individuals who have the manager password.
Each user can be assigned a security level, which is used to determine
permitted operations. Three security levels are defined by the software:
Technician (least privileged), Manager (intermediate privilege), and
Service (maximum privilege–reserved for CANNON
® Instrument
Company service personnel).
Users log in when using the software by typing their name and (optional)
password in the Log In window. Different security levels offer different
CAV use options. Technicians are permitted to access operational features
required for testing samples and performing other routine operations.
Managers may access advanced configuration and reporting options. The
Service level permits access to all instrument and security parameters.
Initial security setup
The VISCPRO ® software installation creates a security account for one
manager with a blank password. After VISCPRO ® installation, a pass-
word should be assigned for the manager using the Change Password
menu option from Main. Managers may add or change accounts for
technician status personnel.
Use the Log In feature to identify the CAV operator and/or access
security functions.
NOTE Once an operator is logged in, that operator’s name is associated with
any sample data obtained during that VISCPRO session. The operator
name may be included in analyses.
