ALPHA-T front panel connections

From top to bottom:

|
| minisas-C - links 8-11
| minisas-D - links 12-15
|
| ethernet sfp - use copper sfp only
| minisas - not used, do not connect
| esata - clock in, trigger out
|
| minisas-A - links 0-3
| minisas-B - links 4-7
|
| LEDs
|

MiniSAS flail cable connections:

P1 <--> link 3
P2 <--> link 2
P3 <--> link 1
P4 <--> link 0

Firmware update procedure

• use quartus to generate the grifc.pof file (use grifc.cof)
• open quartus programmer
• attach grifc.pof to the 1st CFI_512 flash
• mark program/configure for the same flash (3 marks: pof, page_0 and OPTION_BITS
• check that "initiate configuration after programming" is set in tools->options
• say "start"
• should take about 5 minutes
• grifc should reboot into the new firmware

ALPHA-g trigger functions

Trigger modes:

• software trigger
• pulser trigger
• trigger on GRIF16 ADC NIM and ESATA inputs
• adc16 grand-or
• adc32 grand-or
• adc16 multiplicity (plus adc32 multiplicity?!?)
• trigger on coincidences of ADC links

Control registers
