IDC radialXX analog interface specification
this document describes AAT ICAS design specifications for the IDC radialXX analog interface. ICAS IDC radialXX is specified for a limited implementation of the AAT ICAS 2120-radialDAI decimal analog interface specification. the radialXX dial is based on a major unit phase of 20 major units per main unit, thus limiting conditions for the decimalization of dial units.
dial identification
strict implementation of radialXX interface requires a dial identifier such as any of the following: 'XX', 'dialXX'. 'HH', 'dialHH', 'HalfHubble', or 'dialHalfHubble'.
dial indices
strict implementation of radialXX interface requires a system of dial indices consistent with AAT ICAS 2120.
table 2150.1 ✧ unit configuration of radialXX 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) | 20 | 1 half-hubble (t050 or 50 millichrons) | 0 (0 to 19*) |
minor unit | 1 half-hubble (t050 or 50 millichrons) | 50 | 1 millichron (t001) | 0 (0 to 49*) |
subminor unit | 1 millichron (t001) | 100 | 1 tik (tt010) | 00 |
* systems of 20 and 50 indices can be superimposed on a system of 100 indices, however impose certain labeling considerations. |
unit phasing
strict implementation of radialXX 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 2135.2 ✧ unit phasing of radialXX 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).
