Overview of the external interfaces

A- SIREN-LVPS-HK- Purpose is to initiate a turn ON/OFF initial procedure for the instrument- Technically : two open drain links (SIREN-TOR) over the ± 12 V and 3.3 V converters of LVPS-HK B-SIREN-HK- High level commands implying the instrument life (turn ON/OFF of various components by

the action on their supply voltage through HK)- Standard Telecommand (TC) for the instrument control, - Standard Telemetry monitoring (TM) on the power supplies (Voltage), Temperature of the

components,- Technically : RS232/RS422 interface

C-SIREN-CPU- Retrieve information on runs and events like the trigger rate,- Retrieve information from selected events according criteria adapted to the allowed

transmission rate,- Issue CPU commands.- Technically Ethernet RJ45

Conclusions

• Component links done according state of the art EMC rules• Refer to the Electrical Architecture document and Pierre Prat’s

presentation,

• All connectors and pin assignment done for each component,• Refer to the Electrical Interface Document and to Michel Dupieux’s

presentation

• Cables procurement attributed,• Refer to the subsystem manager’s presentations

• Functions and purposes defined,• Refer to the software documents for numeric interfaces and Francesco

Cafagna’s presentation

• No remaining Open point
