3.11 Beginning Configuration
Ensure that the Telephone Access Controller ID is setup. This address is set by
the SW1 DIP switches on the Telephone Access Controller (Figure 41). The
individual switches are numbered 1 to 8 from left to right, and are marked as
either ON or OFF. The first six switches (1, 2, 3, 4, 5, and 6) set the address ID.
Every TX3 System controller requires a unique ID. The unit ID settings do not
need to be in sequence but it recommended to assign IDs starting from 1, using
increments of one (for example, 1, 2, 3, 4, and so on). Unit IDs must not be
duplicated on an RS-485 network.
DIP Switch 7 on SW1 must be set to ON for Touch Screens, and OFF for non-
Touch Screens.
