MULTIMIX 8/4 DIGITAL
Input resistance: 40 kOhm
We recommend the use of linear potentiometers 1 k or 5 k.
With long wirings you need to use shielded cables (as shown in the illustration).
When using linear potentiometers and a scale of 0 – 10, you can determine the influence of
the external controls according to the calculation method mentioned in item 3.
8 b) External configuration switching:
The control inputs for changing the configuration are BCD-coded.
The inputs are preset at 5V with an internal pull-up resistance (4k7), hence their inactive
condition is „logically 1“. The switch takes place by changing to 0 Volt.
config.no conf8 conf4 conf2 conf1 config.no conf8 conf4 conf2 conf1
#1 1 1 1 0 #5 1 0 1 0
#2 1 1 0 1 #6 1 0 0 1
#3 1 1 0 0 #7 1 0 0 0
#4 1 0 1 1 #8 0 1 1 1
The switch will become effective only if and when it is cleared by the software (see software
description „edit“ / „project preferences“ and „tools“ / „enable configuration“ respectively).
With configuration #0 (no switch is activated, all inputs are at „1“) the device chooses the
preset start configuration (see software description). In this condition the switch can be
executed via the PC.
Choosing a non-defined configuration does not cause any changes.
