PC Presenter

Programming the PC Presenter for Use With an Axcess 
Central Controller

The PC Presenter can be connected to a Central Controller via AXlink, to control devices on the 

AXlink bus. The following sub-sections describe the Axcess commands for the PC Presenter.

Creating a buffer for keyboard input

To recognize keyboard keystrokes in an Axcess program, you must create a buffer for the device in 

Axcess. To create a buffer, use the CREATE_BUFFER keyword. This keyword can only be placed 

in the DEFINE_START section of your program. The syntax is shown below:         

Standard keystrokes fill the buffer as ASCII characters. Special characters come in as their 

embedded code equivalents as shown in the Send_Strings table on page 24 of this manual, in the 

Send_Strings subsection. For more information on using buffers, refer to the 

Axcess Programming 

Guide

.  

Send_Commands

Use the Send_Commands listed in the following table to program the Axcess Control System and 

the PC Presenter. Refer to the 

Axcess Programming Guide

 for additional programming information.   

Programmed keystrokes are not saved in permanent memory until program mode is 
exited.
