3.2.12 Borealis Build Options and Power-up Settings
The Borealis is a “Plug and Pray” device, whose operation depends on the
software. Except as documented in Section 2.3.3, there are no user
jumpers.
The Technical Manual documents a number of register preloads and
functional settings that are determined by 0 ohm resistors installed during
manufacturing and read by the Borealis on power up.
Note: Software cannot override the values set by the 0 ohm resistors.
Please contact Rastergraf if it is necessary to change a value.
