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.
