Maintenance
NOTE:
Do not attempt to open the unit to make any adjustments or repairs. In the
event that an operating problem occurs, contact a member of Crestron’s technical
support team. Refer to “Further Inquiries” on page 17.
The CPC-CAMI has been designed to eliminate the need for periodic maintenance.
Lubrication for all moving parts is permanent. Motors, switches, and other moving
parts are rated in excess of normal expected operating life of the unit.
Programming
Position/Rate Mode Definition
In position mode, a voltage corresponding to a position of the lens (focus or zoom) is
fed to the lens interface and the lens moves the motors to the position that
corresponds to the input voltage. In rate mode, the voltage fed to the lens
corresponds to the rate and direction in which the motor moves. The result is smooth
lens movement.
Most lens types operate in rate mode. If position feedback is provided then
focus/zoom presets can be recalled. Without feedback, lens presets cannot be
achieved in rate mode. Some lenses can switch between rate and position mode; the
CPC-CAMI provides the appropriate connections to facilitate this. This type of lens
can achieve “virtual” presets without true feedback pots from the lens.
Programming the CPC-CAMI in SIMPL
SIMPL (Symbol Intensive Master Programming Language) is an easy-to-use
programming language that is completely integrated and compatible with all
Crestron system hardware. The objects that are used in SIMPL are called symbols.
SIMPL Windows offers drag and drop functionality in a familiar Windows®
environment.
SIMPL Windows is Crestron Electronics’ development environment for
programming Crestron control systems. It provides a well-designed graphical
environment with a number of workspaces (i.e., windows) in which a programmer
can select, configure, program, test, and monitor a Crestron control system.
Two sample SIMPL Windows programs are presented in this document for the two
separate lens control configurations. The first subsystem supports lenses that use
CPC-CAMI jumper boards A, B, or D. The second subsystem is specific for lenses
using CPC-CAMI jumper board C and have the separate rate/position drive.
NOTE:
The following description assumes that the reader has some knowledge of
SIMPL Windows. If not, please refer to the extensive help information provided
with the software.
NOTE:
The earliest version of SIMPL Windows did not have a “CPC-CAMI”
available from the Network Control Module folder in the Device Library of SIMPL
Windows’ Configuration Manager. When using an earlier version of SIMPL
Windows choose “CNCAMI” from the Device Library instead. However, realize
that the full functionality of the CPC-CAMI cannot be fully defined by the
“CNCAMI” symbol. Crestron recommends a SIMPL Windows and operating system
upgrade to fully implement CPC-CAMI functionality.
