RCP-ME User Guide (v4.0) Category Index Mode • 57
Category Index Mode
Category Index mode allows alpha-numeric extensions to labels to 'build up' the final label selection. For example,
VTR 1 - 6 may be expressed as a VTR label with numerical extensions 1 through 6. Similarly, alpha extensions may
be used, for example, VTR A - E for VTRs A through E.
Destination and source names are split into substrings - the first substring traditionally referred to as the category ,
and subsequent substrings as the indexes (i.e. Category VTR index 1 through 6). As source/destination names
become more complex, an index may not be the final part of the selection name. For example, consider the source
names CG TX 1 and CG TX 2; Category Index mode may be configured so that a user selects
CG
, then
TX
, then
either
1
or
2
. This may be extrapolated to cover a large range of sources and destinations.

Category Index mode is available on RCP-ME firmware 1.48 or higher connected to Ultricore v2.0 or higher.
Default Category Button Mapping
The RCP-ME panel has a fixed 40 button layout. The first five buttons are assigned to category navigation, leaving
35 buttons available for categories. The assignment of categories to buttons is an automatic process and cannot be
altered.
By default, the category names (from the Ultricore database) are assigned left to right immediately following the
navigation buttons. After the category names are accounted for, then the index names will be applied. The
assignment of categories and indexes are alpha-numeric in order. (

Figure 9.2 illustrates the RCP-ME button mapping if the Ultricore database defined five categories and ten indexes.
