Debugging Support
The following comments are suggested to assist
you in the event you need to debug the EASY CPU
extended camera protocol handlers.

In the Camera Status screen, the Dome/PTZ
On-Line column is unable to show the status
because the extended protocols are simplex
data routed one-way to the dome/PTZ device.

Additionally, the Ping test that is normally used
to test domes is not operational for the same
reason (simplex data one-way).

You should verify the correct data rate setting
in the Direct Dome/PTZ Connections screen as
compared to the dome strapping or set-up.
Also, you should verify the dome/PTZ address
strapping or set-up is correct.

Verify the correct protocol handler is selected.
The information contained in the Protocol
Handler Form may be useful in verifying that
the correct handler is being used.

The distribution panel LED indicators display
Power-On/Heartbeat status, Host data detect,
and Channel 1-16 data detect. Use the
distribution panel line status test switch to
verify connections and operation.

When you read in an XML file, EASY CPU
checks to ensure the basic, required protocol
handler sections are present. If any of these
sections are not present, error messages are
displayed. If the parameter values have been
improperly set or omitted, this error condition
will not be detected until an attempt is made to
control a camera and it does not work
correctly.
Overview of Camera Control
Definition Files
The camera control definition file is a text or XML
file with the information formatted as an XML
document. It tells the generic camera control
handler in the MP3200 system how to
communicate with a particular type of camera
controller.
You can create this file in any available text editor.
The easiest way to create a handler file is to copy
an existing file and edit it to meet your needs.
Before you begin you will need to know:

What camera control functions are supported
by the camera

What byte streams need to be sent to the
camera for each function

How to specify the list of supported functions,
and their associated byte streams in the
definition file for the generic handler.
Notes: Remember the following points while
working in XML:

Tag and attribute names are case sensitive.

If you misspell a tag or attribute name, it is
typically ignored and assumed to be something
new. Only known tags and attributes are
noticed.

If the open and close tags are not identical, a
syntax error will occur.

Normally, white space (blank characters) prior
to and following any value is ignored. However,
this implementation preserves all white space
inside Templates.
Creating/Editing a Camera
Control Definition File
It is easier to start by copying an existing XML
definition file designed for a particular camera, and
then modify it as needed.
The following elements are important when
creating a camera control definition file:

Display Name

Serial Port Configuration

Data Rates

Capabilities

Parameters.
