AMX AXT-CA10 Instruction Manual page 12

Introduction
If either a Camera or Video Display (such as a Projector/Plasma and TV) are chosen
to be controlled via Serial (RS-232), two new fields become available within the
Device Data section. Place a checkmark in the Use remote serial interface field to
indicate you are using an external serial interface or leave it unchecked to use a
Serial port on the Master.
If this option is checked, you can choose which port on the serial interface to use by
choosing a port from the drop-down list. This was implemented to communicate to
some cameras and display devices that are not located near the Master.

Support for NI-700 NetLinx Integrated Controller
This new controller is treated the same as any of the other NI Series of Integrated
Controllers. If the project calls for more ports than the NI-700 can provide (2 Serial and
1 IR), it is not selectable as a system controller via the DXP-PRO wizard.
Support for Cameras
This new far-end control of external cameras (using Serial control ports) is possible by
supporting them as a Source type (external to a video conferencing unit) using a remote
serial interface operating on a selected port. Their selection is added as a choice from a
drop-down selection list within the Camera Control section of the Device Data tab. These
cameras must first be added as a Source type within the same Device Data tab of the
Device Configuration dialog page before they can be used by other sources such as a
video display. This feature is only supported within G4 touch panels.
Support of remote serial interface usage (Display devices and External cameras)
This new support is added as way of providing far-end control of external cameras and
display devices using Serial control ports. This is accomplished by allowing you to
choose either Camera or Display as a selectable Source Types within the Device Data
tab of the Device Configuration dialog page. This feature allows you to extend their
"reach" and control an external camera directly by parsing out Send Commands to the
external Serial control ports. Local control of cameras is done indirectly via the use of
AXB-PT15 camera controllers.
Support for MeetingManger
This new support is added as a selectable option within the Integrated Applications
dialog page. Enabling this option, provides the ability to enable touch panel pages to
support the on-screen display of room scheduling and appointments. All queriable
devices within the target environment such as: source/display/switching devices, and
AMX devices (touch panels and NXA-UPSs) can be monitored via the MeetingManager
application.
No scheduling capabilities are available through the DXP-PRO touch panels and must be
done through the actual RMS (Resource Manager Suite) application interface.
To enable online/offline notification, the programmer would need to write custom
Resource Manager NetLinx code within the DXP-PRO project file that is downloaded
to the target Master. This custom code is written within the custom.axi file.
