Configuration
Local Onboard Module Configuration
The 8921DAC 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, AA (Analog Audio)
1/2 MODE, AA 2 MODE, and CONTROL.
The AA 1 and AA 2 MODE rotary switches select the output mode for
each analog audio pair from output processing settings. Local settings
for each output mode are given in
Table 5 on page 22 .
The CONTROL switch is used to set the available module parameters
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.
Note 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.
