HIA/DRAO ACSIS Correlator Crate Software Outline • System Overview • System Interfaces • Observing Protocol: How ACSIS is used • Software components and structure ACSIS Internal Design Review, 21-23 June 1999

HIA/DRAO ACSIS Correlator Crate Software Main Functions • Configure and control correlator modules in a crate • Provide test facilities • Readout lag and status data from correlator modules • Sum lag data • Send correlator module data to DRAMA tasks that are monitoring it.

HIA/DRAO ACSIS Correlator Crate Software External Interfaces • Configuration and observing parameters passed in ASCII space-delimited text files. – Parameters can also be modified, sent, retrieved using DRAMA set and get commands. • Control Commands sent using DRAMA obeyw commands – REBOOT – CHECK_HEALTH – INITIALISE – START – STOP ACSIS Internal Design Review, 21-23 June 1999

HIA/DRAO ACSIS Correlator Crate Software External Interfaces (continued) • Data “Exported” to Reduction system using DRAMA parameter monitoring facilities. Data tagged with sequence numbers. • Integration and readout controlled using RTS signals – Sequence Number – Sequence Valid – Data Valid – Subsystem Ready ACSIS Internal Design Review, 21-23 June 1999

HIA/DRAO ACSIS Correlator Crate Software Observing Protocol • Steps needed to use the correlator during an observation. • Ingredients: – Low-level Crate configuration file – DRAMA obeyw INITIALISE – DRAMA set StartSeq x EndSeq y – obeyw START ACSIS Internal Design Review, 21-23 June 1999

HIA/DRAO ACSIS Correlator Crate Software Observing Protocol (continued) • Procedure: 1) Generate configuration text file. 2) Send a DRAMA obeyw INITIALISE. Completion means the configuration file was read. 3) Optionally, send DRAMA set commands to modify any parameters. 4) Send a DRAMA set commands to set the start and end sequence. 5) Send a DRAMA obeyw START command. 6) Setup and run RTS so it generates sequence numbers. 7) When the End Sequence is reached quit or continue at step 2, 3, or 4.
