Configuration
Configuration
The 8920ADC can be configured locally using onboard switches and
jumpers or remotely using the 8900NET network interface.
The following parameters must be set on the 8920ADC module:
■ Output level (Left and Right) – coarse and fine adjustment of analog
input levels for full scale digital outputs,
■ Output mode – channel swapping, summing, tone and phase inver-
sion, and
■ Control mode – Local/remote or local control only (remote lockout).
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 on
page 8 . 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.
■ SW2 and SW3 (toggle) switches – provide fine adjustment of the left
and right channel input levels.
■ 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.
