JMDC Application Programs JAP

1
JMDC Application Programs (JAP)

• Xudong CAI _at_ MIT
• March 1, 2005

2
Supported Functions

• Based on JOS V1.12, JAP was tested during FIT
• 1553 Communication on both ISS and STS interface
  were tested, APID and external NASA commands were
  modified and supported during FIT
• HRDL and RS422 communication are working, but
  HRDL output procedure need to be modified
  according the test result of APS
• Data acquisition is working, but need to be
  optimized
• Passing commands from one JMDC to other nodes is
  working
• Slow control Q list is supported, but need to be
  improved

3
Problems to be fixed

• Go from very low output rate to higher rate, JAP
  takes too long about 10min.
• This will be fixed in March 2005

4
Functions to be added CAN Test

• Passing Encapsulated AMS CAN Block
• JIM-CAN bypass mode support
• USCM simultaneous debugging task
• Improved Q-List
• These works can be finished in March 2005

5
Functions to be added - Board/Crate Level Tests

• In order to use JAP for FM and FS board level
  test, some board level debugging task need to be
  added
• JSBC ECC mode, should be enabled in JOS and used
  all the time
• Watch-dog timer functions need to be added
• Passing encapsulated data (AMS CAN block, AMSWire
  Block, Frame and AMS Block)
• JBU usage to be added
• Define crate level test procedure
• These works can be finished in April-May 2005.

6
Functions to be added Slow Control

• Need clear definitions procedure for each control
  task
• JPD monitor and control

7
Functions to be optimized

• Data acquisition procedure
• Q-List
• Parameter setting (unify between JROM and JAP)
• Status reporting (unify between JROM and JAP)
• Flash memory system (unify between JROM and JAP)
• These are continuous works.

8
Data Format and Procedures

• Critical Health Data (CHD) format need to be
  modified
• NASA Commands need to be redefined
• Some operational procedure need to be defined
• Ownership setting
• Passing data between JMDCs
• Default parameters in flash memory
• Status gathering (JMDC part)
• HRDL transmission startup
• Common data types between JROM and JAP
• HRDL parameter changing
• How to use JBU (storing blocks or frames)

9
Ground Support Software

• Separate commanding and HK handler
• Recording file format and software
• Commanding path
• Monitor programs
• Commanding program
