C5000 POS Translator
The current C5000 POS Translator (78-9236-6753-5) will function
only
with the current 0 thru 9-key
(model 2475) Station Selector (78-9236-6513-3). It is
not
backwards compatible with the original 8-
button (model 5208) or 16-button (model 5216) Station Selector.
If a customer needs to order a POS Translator, you need to ask whether it is to be used with a current
(model 2475) Station Selector or with the original 8-button (model 5108) or 16-button (model 5116)
Station Selector.
The 3M Repair Center will repair or replace the original POS Translator (78-9236-6387-2) as needed.

Wiring ONLY for the RS485 buss on the C5000 and Performance Series Intercoms:
These wires
also supply DC power to the Station Selectors. When installing a Station Selector for the C5000 and
Performance Series Intercoms we recommend adding a separate power supply to the Station Selector if it
is located more than 100 feet from the Communications Controller.
