Example:
Isolator
(DBA-8Z) Address
Range SW6
Position SW7 setting Comment
1 103-107 1 (1-8) 2, 4 ON (+102) Choose 1-8 then add offset +102
2 108-112 2 (5-12) 1, 2, 4 ON (+103) Choose 5-12 then add 103
3 114-122 4 (13-20) 1, 4 ON (+101) Choose 13-20 then add 101
In the example above, Isolators 1 and 2 use only five phone connections each; the last
three outputs of Isolator 1 would be 108, 109, 110 which, although unused, conflict with
the first 3 addresses of Isolator 2; similarly with Isolators 2 and 3. Solution: disable the last
three outputs of each isolator.
Disabling phone outputs: (Note 1st and 2nd phones cannot be disabled)

Confirming status of Isolator Outputs
To confirm which phone outputs have been disabled, set SW6 to 0 and SW7 to ‘All OFF’
and press the Test button; each output will have its status LED flash once in turn except
those outputs which have been disabled. Note it may be necessary to press the Test
button a second time on a live system to ensure that the PCB has been reset.
