Configuration
Configuration
The 2020ADC can be configured locally using on-board switches and
jumpers, or remotely using the 2000NET network interface. Configuration
and adjustment items for the 2020ADC include:
• Input level (Ch 1 – Ch 4) – gain adjustment of analog input levels for
full-scale digital outputs,
• Output mode – channel swapping, summing, and phase inversion, and
• Control mode – Local/remote or local control only (remote lockout).
Local Onboard Module Configuration
The 2020ADC module can be configured locally using the jumper, the
rotary switches and four paddle switches shown in
Figure 7 . The CONF
LED indicates status of the configuration process.
These components perform the following:
• Jumper JP2 sets control mode for Local only or Remote and Local.
• Function (rotary) switches SW2 (CH1/2) and SW 5 (CH3/4) select the
desired output configuration (0 through 9, A through F). Either func-
tion switch position 0 or F (Factory defaults) can be used to return the
module configuration to the original factory default settings.
• Paddle Switches (CH 1 – 4) adjust the gain of each analog audio input
channel for full-scale digital outputs.
• CONF (configuring) LED, when on, indicates the module is initializing
or processing configuration information.
