Commands implemented by the XPT620 control interface

Commands are a single character followed by parameters. There are no separators between the command and parameters.

Page Identity

A page identity is a five digit number of the format mppss. Trailing digits can be omitted and default to '0'. Digits may be replaced by a wildcard '*'. The fields are:-

  • m = Magazine Number. In the range '1' -'8'.
  • pp = Page Number. Two hexadecimal digits. In the range '00' 'FF'.
  • ss = Subpage. A two digit number in the range 00-99. This is an internal reference used to identify subpages and repeated page versions. In the range '00' – '99'.

P – Select Pages for Action

Function

The select page command is used to identify a page or set of pages for subsequent action. In defining the page or pages within a select page command, it is necessary to be able to identify the desired page or pages without ambiguity. This is done by use of the 'Page Identity', the constituent parts of which are explained in section 2.2. Syntax P where: Page Identity elements are defined in section 2.2 Acknowledgements The following acknowledgements are possible: 0 = Good Command. Page(s) specified identified within this unit. where : nnn = number of matched pages placed on Page Action List 1 = Bad Command e.g. page identity unacceptable or wild card used and no match found. <001>8 = Command valid but the page did not exist. This only works when not wildcarded and afterwards the page will exist as a newly created empty page. Examples P888,P888**,P8**,P*** All pages will be selected. P****1 Default Page 1 will be selected
