As shown in the [[:Image:SiPM FPGA and EEPROM Connections.gif |connection diagram]], 4.7kΩ pull-up resistors are necessary to pull up the DONE, INIT_B and PROG_B pins to VCCO.

=== LED-less RJ-45 Jack ===
Since we want to keep the enclosure as dark as possible, we must use an Ethernet jack with no built-in activity/link LED. There are many suitable jacks available. Most likely, we will want a shielded jack such as the Stewart Connector Systems SS-6488S-A-NF ([http://search.digikey.com/scripts/DkSearch/dksus.dll?pname?site=us;lang=en;name=380-1024-ND Digi-Key Part #380-1024-ND]). However, there are many other LED-less jacks available that may also be suitable. For a listing of other LED-less jacks, look at the [http://digi-key.dirxion.com/Main.asp?from=emailafriend&pagenav=&bookid=2&pageindex=306 Digi-Key Interactive Catalog].
