EXPANDER DIPSWITCH SETTINGS
Expander addressing and the LEDS are controlled by DIPswitch SW1.
SW1-1 to SW1-3 are used for expander addressing. Expanders must be numbered sequen
-
tially from 1 to 7. The address is configured as follows (X indicates OFF) :
If an expander address is changed, the unit must have power removed and then reapplied in
order for the master to recognize its new address. All the expander’s programmed parame-
ters, aside from the voice messages, will reset to the default parameters when its address is
changed and will have to be re-programmed. When the expander is powered back up, “Pro-
gram code error” will be announced, indicating that the expander was reset. Only the ex-
pander with the changed address will reset. The master and the rest of the expanders will
retain their programmed parameters.
SW1-8 is used to turn the LEDs on and off. SW1-4, SW1-5, SW1-6,and SW1-7 are not
used.
