Internal Programming Options (CPU)
All internal programming is made via printed circuit board (PCB)
mounted switches on the module’s card. With the exception of the reset
and serial select switches, which are momentary push-button switches, all
programming is via 4-position dipswitches (total six).
For the purposes of this manual, we will assume you are holding the re-
moved module upright, component side towards you, with gold-plated card
fingers to the left and the module faceplate to the right. This will enable you to
read the control legends silkscreened next to each programming switch. Note
when a dipswitch position is thrown to the right (towards the module’s face-
plate) it is ON.
Global Settings
Four-position dipswitches SW2-SW5 (lower right corner of card)
determines various console operating parameters:
Bit Weight
SW2 position 11 0 1
SW2 position 12 1 2
SW2 position 13 2 4
SW2 position 14 3 8
SW3 position 21 4 16
SW3 position 22 5 32
SW3 position 23 6 64
SW3 position 24 7 128
Note: Each D-8000 Console ID# is set using dipswitch positions 11-14
and 21-24. These switches are read as an 8 bit field with Bit Ø mapped to
DSW11 and Bit 7 mapped to DSW24. This ID# is read by the CPU at boot
up and is required by D-8000 serial communications software.
Example: Desired ID=17, set DSW21 and DSW11 “ON”
In multi-console, RS-485 connected system, each D-8000 console
MUST have a unique Console ID#. Default Console ID is 1
(DSW11=”ON”).
SW4 position 31- Ignore serial input checksum byte
(default is “OFF”)
SW4 position 32 - Not used
SW4 position 33 - Not used
SW4 position 34 - Not used
Note: Some automation systems may require DSW31 to be set “ON”.
