9. Programming via Shareport
In order to ease customization of the ida FS 250, FSL parameters 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. Function Y 249 is automatically deactivated after
timeout on the shareport (i.e. settings defined in Y249 cannot be saved in
the NVRAM).
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.
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.
