Digital Front End Board MIL-STD-1553 Interface for SciFi detector electronics:
Python package provides a GUI interface to the DFE Controller boards using EPICS and the VxWorks Online Control Processors.
What we want is a remote, fast and reliable access to DFE boards
Compact Flash Card
(as well as communications with sequencer controllers, VRBCs, Vicors [power supplies], and AFE crates).
LVDS Control, Monitoring and Diagnostic tools
Controller can be found only in three states:
Right click to access DFEC commands:
View boards: permits to get standard status information of all DFE boards attached to the DFE Controller
“At A Glance” will display initialization status of DFE boards
“In Detail” will display more detailed information.
DFE status Color code:
“At A Glance” view:
You can click on each DFE panel to get DFE detailed view:
Slow monitor userbits information: important byte for DFE diagnostics
Right click on the panel will let you execute more advanced DFEC commands (Please do not do that unless you are an expert!):
You can get DFE detailed status info for every DFE boards by selecting “In Detail” view:
DFE status Color code:
If firmware is being downloaded to the DFEC CFC via 1553, this LED will blink!
In the past, DFE firmware downloads (or any heavy DFEWare 1553 traffic) resulted in unsuccessful downloads of AFE crates x50-x53!
Thus: experts who decide to download firmware via 1553 must coordinate their efforts with CFT shifters!
Select from menu Monitoring, then DFEA Status Info:
By clicking on each particular trigger sector, one can access more detailed info here:
Yellow color corresponds to changes in running conditions.
For example: DFEAMonitor when run is paused (L1Accept is off):
Press “Reset DFEA Monitor” to clear the display.
CTOC Monitor is done similar to DFEAMonitor:
DFEWare has a number of different diagnostic tools.
Here is described a tool to check the status control bits that are transmitted from AFE boards to MIXR boards:
Select “Diagnostics” from menu
Select AFE->MIXR tests
Select “Display AFE-Mixer Link/SYNC bits”
Please do not run any other diagnostic tools unless you are an expert!
DFEWare is a robust tool to configure, monitor and control SciFi DFE boards.
