3.2. Connecting cables to the Sirius Breadboard

Figure 3-1

– ÅAC Sirius Breadboard with connector numbering

The Sirius Breadboard runs on a range of 4.5 to 16V DC. The instructions below refer to the
connector numbering in Figure 3-1.



Connect Ground to the black connector 1



Connect 4.5 - 16 V DC to the yellow connector 2. The unit will nominally draw
about 260-300 mA @5V DC.



Connect the 104451 ÅAC Debugger and Ethernet adapter with the 104471
Ethernet debug unit cable

to connector 3. Connect the adapter USB-connector to

the host PC. The ÅAC debugger is mainly used for development of custom
software for the OBC-S with monitoring/debug capabilities, but is also used for
programming an image to the system flash memory. For further information refer to
chapter 3.6.



For FPGA updating only: Connect a FlashPro programmer to connector 4 using the
104470 FPGA programming cable assembly. For further information how to update
the SoC refer to Chapter 9.10.



For connecting the SpaceWire:

o

Option 1: Connect the nano-D connector to connector 5 or 6. Be careful
when plugging and unplugging this connector.
