Configuration
Local Onboard Module Configuration
The 8920ADC module can be configured locally to set parameters using the
jumpers, the rotary switch and two toggle switches shown in
Figure 5 . The
CONF LED indicates status of the configuration process.
These components perform the following:
• Jumper JP7 – sets control mode for Local only or Remote and Local.
• Jumpers JP5 and JP6 – set coarse input level adjustment for left and
right channels as explained in
Setting Maximum Operating Level on
page 14 ).
• SW2 and SW3 (toggle) switches – provide fine adjustment of the left
and right channel input levels as described in
Using Level Gain Toggle
Switches on page 14 .
• Function (rotary) switch – selects a desired output configuration (0
through 9, A through F), although not all positions are used.
• CONF (configuring) LED – when on, indicates the module is initial-
izing or processing configuration information.
Note Function switch positions 0 and F (Factory defaults) can be used to return the
module configuration to the original factory settings.
