Segment display module Segment display module
This module has the same connection as the internal segment display. It differs only in the cable and connector type because
it is supplied as an ECR accessory.
Alphanumerical display module Alphanumerical display module
This display is controlled by an independent microcontroller C-D2500, which accepts the data from the main microcontroller
via the serial line (EX1-SEL, EX1-CLK, EX1-DATA or EX2-SEL, EX2-CLK, EX2-DATA signals). This processor is placed on an indi-
vidual PCB under the alphanumerical display module.
