Response for Requesting Variable Data
Change the InView Display Address
This function allows the ability to change the serial address in a
display. For example change display address 001 to address 020.
When doing this, you need to know the address of the display you
want to change. This is typically done using the automation software.
The following is an example of changing a display (with the address
of 005) to address 004.
