Segment display communicates with the main microcontroller E-N using the LCD-SEL, LCD-CLK and D-LCD signals.

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

This display is controlled by an independent microcontroller C-D, which accepts the data from the main microcontroller

via the serial line (EX-SEL, EX-CLK, EX-DATA or EX-SEL, EX-CLK, EX-DATA signals). This processor is placed on an indi-

vidual PCB under the alphanumerical display module.

External display interfaces

The connection for the external display interfaces is shown below. There is no difference in the actual connection, only the

signal names differ.
