Configuration and Adjustments

Configuration and Adjustments

Kameleon HD configuration and monitoring can be performed using a web
browser GUI interface or a networked Newton Control Panel. This section
provides an overview of each of these controls along with the configuration
parameters available with each type of control device.

It also provides any configuration discussions needed for understanding
the different functionality of each model.

Kameleon HD Timing Considerations

Several models of the Kameleon HD are offered to meet the needs of dif-
ferent applications in a facility.

One of the primary needs in a facility is for modules whose outputs can be
timed to an external (house) reference. If this is a requirement, modules
with frame sync capability such as the KAM-HD-FS or KAM-HDD-FS are
ideal for this purpose.

An external reference can be inserted into the Kameleon 2000 frame and fed
to the 2000GEN module which distributes this external reference to every
module in the frame. Each Kameleon HD module with frame sync capa-
bility can be set in System Configuration for an output timing source of
Frame Reference and will match the external reference input to the frame
with no special considerations for the input signal.

The other two modules available in this series, the KAM-HDD and the
KAM-HDD-PA, can be used in the same frame but do not provide frame
sync capability. In order for the outputs from these modules to be in time
with an external reference, the input signal to these modules must already
be in time with the external reference when it is input to the module and
the Output Timing set to Frame Reference. If this condition is not met, an
image break can occur when switching sources.

When the input signal is in time with the external reference, using the
Frame Reference setting will put the delay of the output signal to within a
very accurate and predictable delay of approximately one nanosecond
thereby matching the external reference timing.
