DDI-8 INSTALLATION AND OPERATION MANUAL
The DDI-8 has five field addressable switch settings to designate dialer board numbers. The
switches operate on binary code system. The DDI-8 ( System 3000 ) will recognize any number
from one to 31. Do not use zero!
For example, to designate the DDI-8 board as No. 12, turn both SW3 and SW4 to OFF. SW3 = 4
and SW4 = 8. SW3 (4) + SW4 (8) = Board Number (12). Do not duplicate board numbers!
Each card should be assigned a different number. Refer to the table below:
Board
Number

01
02
03
04
05
06
07
08
09
10
Note: The digit '1' indicates an 'ON' switch.
CAUTION ! If you are using a network with several DDI-8 cards it is imperative
that you do NOT duplicate card numbers in any SYSTEM 3000.
Switch number 6 is used to select the DDI-7/8 mode. On SYSTEM 3000 units with Program
S600 Standard 6 software version or higher, the factory default setting for SW6 is ON. (For
units with other software versions or CPU V refer to Section 4 Retrofits.)
Switch number 7 is reserved for system self-test. The DDI-8 default setting is OFF, (enabling
the partial diagnostic test mode.) If SW7 is changed to ON, the full diagnostic test mode is
enabled. Refer to table below.
