If necessary, change the MIM's site assignment
number to match the site's Site ID number by
setting the binary equivalent at SW1 and SW2.
Figure 3 is an example with the site assignment
number set to 13 (decimal). Again, the factory
setting – site assignment number = 1 – is shown in
Figure 2 and in the DIP Switch Settings diagram.
A Controller Board must be reset after a DIP
switch change.
NOTE
If the MIM's site assignment number is changed to
2 (decimal), the VMIM site assignment number
must also be changed from its factory setting of 2
(decimal). The MIM and VMIM site assignment
numbers cannot be identical.

Settings Example (Site Assignment Number = 13)
NOTE
If, during servicing/troubleshooting procedures for
example, a Controller Board must be moved to a
different Card Cage slot, its DIP switches should be
set in accordance with the DIP Switch Settings
diagram in this manual for the particular Card Cage
slot which it will be installed within. A Controller
Board must be reset after a DIP switch change.
Audio Boards
All Audio Boards within the Compact CEC are located
in the upper or primary Card Cage – Card Cage 1. Each
Audio Board has one 8-position DIP switch which allows
configuration of three basic board parameters: board
number, EEPOT board power-up setting, and 2175/8700 Hz
tone selection.
The board number setting sets which group of four (4)
audio channels the board is assigned to and wired for (board
1 = channels 1 - 4; board 2 = channels 5 - 8; etc.).
The EEPOT power-up setting is basically not used since
a Controller Board initializes the EEPOTs on its Audio
Board(s) in accordance with the MOM's configuration. This
occurs at system power-up or if either the Audio or
Controller Board is reset. Essentially, these switches are
only useful for diagnostic procedures when a Controller
Board is not connected to the Audio Board.
The 2175/8700 Hz tone selection must be set to match
the tone frequency sent out from the installed Clock Board.
With the existing Clock Board (19D903305P1), the 2175
Hz tone should always be selected.
At the factory, before installation into the Card Cage,
each Audio Board's 8-position DIP switch is set in
accordance with the DIP Switch Settings diagram in this
manual. Normally, Audio Board DIP switch changes are
never required during the installation and set-up process of a
Compact CEC.
NOTE
If, during servicing/troubleshooting procedures for
example, an Audio Board must be moved to a
different Card Cage slot, its DIP switch should be
set in accordance with the DIP Switch Settings
diagram in this manual for the particular Card Cage
slot which it will be installed within.
