IDC radialXL analog interface specification
this document describes AAT ICAS design specifications for the IDC radialXL analog interface. ICAS IDC radialXL is specified for a limited implementation of the AAT ICAS 2120-radialDAI decimal analog interface specification. the radialXL dial is based on a major unit phase of 40 major units per main unit, thus limiting conditions for unitary decimalization and indicialization of the dial units.
dial identification
strict implementation of radialXL interface requires a dial identifier such as any of the following: 'XL', 'dialXL'. 'QH', 'dialQH', 'QuarterHubble', or 'dialQuarterHubble'.
dial indices
strict implementation of radialXL interface requires a system of dial indices consistent with AAT ICAS 2120.
table 2160.1 ✧ unit configuration of radialXL interface
clock unit | completion of unit phase | number of unit indices | indice segment unit | top indice label |
---|---|---|---|---|
clock unit | completion of unit phase | number of unit indices | indice segment unit | top indice label |
major unit | 1 main unit (1.0 Xn or 1 day) | 40* | 1 quarter-hubble (t025 or 25 millichrons) | 0 (o to 39**) |
minor unit | 1 quarter-hubble (t025 or 25 millichrons) | 25 | 1 millichron (t001) | 0 (o to 24**) |
subminor unit | 1 millichron (t001) | 100 | 1 tik (tt010) | 00 |
*system of 40 indices does not fully superimpose onto a system of 100 indices. ** systems of 40 and 25 indices impose certain labeling considerations. |
unit phasing
strict implementation of radialXL interface requires a system of unit phasing consistent with AAT ICAS 2120. all units are phased to the top indice at t000 tt000 IDC and cycle at the following rates:
table 2160.2 ✧ unit phasing of radialXL interface
clock unit | phasing rate |
---|---|
clock unit | phasing rate |
major unit | major unit phase advances 1 major unit segment upon completion of minor unit phase. |
minor unit | minor unit phase advances 1 minor unit segment upon completion of subminor unit phase. completion of minor unit phase advances major unit phase 1 major unit segment. |
subminor unit | completion of subminor unit phase advances minor unit phase 1 minor unit segment. |
particular pointers may rotate continuously or incrementally (please see AAT ICAS 2210).
