CPU & DSP
Internal Programming Options (CPU)
All internal programming is made via printed circuit board mounted
jumpers located on the right lower corner of the Processor Board PR-70
PCB.
Global Settings
Jumpers J29 - J44 determines various console operating parameters:
Bit Weight
J33 0 1
J34 1 2
J35 2 4
J36 3 8
J32 4 16
J31 5 32
J30 6 64
J29 7 128
Note: Each D-70 Console ID# is set by jumpers J29-J36. These
jumpers are read as an 8 bit field with Bit Ø mapped to jumper J33 and Bit
7 mapped to jumper J29. This ID# is read by the CPU at boot up and is
required by serial communications software.
Example: Desired ID=17, install jumpers J32 and J33.
In multi-console, RS-485 connected system, each D-70 console MUST
have a unique Console ID#. Default Console ID is 1 (J33 - installed).
J38 - ignore serial input checksum byte
(default not installed)
J40 - not used
J41 - not used
J42 - not used
Note: Some automation systems may require J38 to be installed.
J44 - not used
J43 - 8dB
J39 - 4dB
J37 - 2 dB
Note: These jumpers set the fader scale factor that will be applied to
each input module at the DSP stage. Default setting is 12dB (J39 and J43
- installed).
