Configuration
Onboard Module Configuration
The 8920DMX module can be locally configured using the jumpers, the
rotary switch, and the paddle switch shown in
Figure 5 . These components
perform the following:
• Jumpers – set control mode for Local only or Remote and Local, and
select audio output type and impedance.
• Function (rotary) switch – selects a desired configuration parameter (0
through 9, A through F), although not all positions are used.
• SW1 (paddle) switch – initiates a configuration parameter selection.
• CONF (configuring) LED – when on, indicates the module is initial-
izing or processing configuration information.
Remote Control Lockout
When a jumper is placed across pins 2 and 3 of jumper block JP10 (see
Figure 5 ), module output mode settings are adjustable from the Local
on-board switches only. To have both Local and Remote access, set the
jumper across pins 1 and 2.
Audio Output Impedance
The desired audio type and output impedance must be selected as bal-
anced 110
Ω or unbalanced 75 Ω with jumpers JP12 and JP13 (AES 1) and
JP13 and JP15 (AES 2) shown in Figure 5 .
