Overview
The AL4020 is designed to receive both a DMX512 input and up to
72 analogue inputs. The two input types are htp merged to form a
DMX512 output.
The start channel of the analogue data on the DMX512 output can be
selected with the BCD switch inputs.
Setting the BCD inputs to "000" disable the DMX512 input and
allows the device to operate as a simple analogue to DMX512
converter without any user controls.
Multiple devices can be cascaded using the DMX512 inputs and
outputs to produce products with up to 512 channel capability.
The insertion delay of the AL4020 is less than 60uS which ensures
that cascaded device designs do not introduce a DMX512 response
delay.
