12. Programming via Shareport

In order to ease customisation of the Xerox FS 5250, FSL parame ters for twinax input can be programmed directly via the interface's Centronics or serial (RS-232) port using the Engineering Function Y249.

The Engineering Function enables the system to detect whether FSL sequences on shareport are intended for twinax FSL input or for shareport setup and will direct the sequences received to the twinax FSL interpreter.

The sequence works as a switch for FSL sequences. The defined Escape Character will also be translated and defined as Escape Character for the twinax FSL module. The ability to set up via the shareport is reset after timeout on the shareport and can not be saved in the NVRAM 10.

The setup sequence must only contain ASCII characters. Apostrophe notation can be used if characters are included in the US ASCII 7 bit character set, all other data must be in HEX notation.

All functions which are accessible from the twinax input can be used via Centronics/RS-232 setup.

12.1. Activating the Y249 Engineering Function

Before the Engineering Function can be activated, an Escape character must be defined:

&&??<character>

The sequence "&&??%" will define "%" as the ESC Character.
