Configuration
Local Onboard Module Configuration
The 8921ADT module can be configured and operated locally using the
rotary and paddle switches on the front edge of the module (
Figure 6 ).
Figure 6. Module Jumpers and Switches for Local Configuration
Configuration Switches and Controls
The switches available for local configuration are described below. Refer to
Figure 6 for the following descriptions:
• MODE and CONTROL (rotary) switches — Three rotary hex switches
are present on the front edge of the module, AES 1 MODE,
AES 2 MODE, and CONTROL.
The AES 1and AES 2 MODE rotary switches select the output mode for
each AES channel from 1 of 16 possible settings. Local settings for each
output mode are given in
Table 6 on page 27 .
The CONTROL switch is used to set input/output gain, delay, save and
recall user settings, and for input selection in conjunction with the
CONTROL paddle switch. It addresses two banks of functions; each
bank has 16 possible positions (0 through 9 and A through F). Not all
positions are used. The next bank of functions is accessed each time the
CONTROL switch makes a complete revolution past zero (or back
through F): While in Bank 1, a complete revolution past zero accesses
Bank 2; while in Bank 2, a complete revolution past zero accesses Bank
1 again. The yellow BANK 2 LED indicates which bank is currently
being accessed.
CAUTION The CONTROL rotary switch should be kept in position 0 in any bank (parked)
when not in use to avoid any inadvertent change in configuration. Position 0
in each bank is inactive.
• BANK 2 (second Function) yellow LED – when off, indicates that the
rotary switch is addressing the first bank of functions. When on, indi-
cates that the rotary switch is addressing the second bank of functions.
