Operation Advanced (DDC/CI) Control Overview
IND100064-51
Introduction
DDC/CI (Display Data Channel/Command Interface) specifies a means for a computer to send commands to the
unit's Display Video Controller to programatically adjust parameters of the display instead of pressing physical
buttons or navigate through an OSD menu. Specific commands to control units are defined in a separate official
Monitor Control Command Set (MCCS) industry standard. The signal inputs supported are VGA and DVI.
Hatteland Display's Series X (Generation 1) - Maritime Multi Displays (MMD) from 12 to 26 inch will support some of
these commands (units with GEV Firmware 160914) and is gradually implemented in production from
13th of February 2017 and fully implemented for units delivered after 31st of March 2017.
Reference: http://www.hatteland-display.com/mails/02_2017_ecn.html
To determine if your unit has the DDC/CI commands supported as described in this chapter, please review
the "On Screen Display (OSD) Menu" chapter (Service section) in this manual.
It is expected that the user have previous experience of the DDC/CI protocol and how to implement the commands
in their own control applications. A suitable starting point for sending commands, are the GUI operated (or command
line version) of softMCCS software, reference: http://www.entechtaiwan.com/lib/softmccs.shtm
The listed DDC/CI commands below are equivalent to the same functions available in the well implemented Hatteland
Display Serial/Ethernet Communication Control Interface (SCOM) protocol, where specified, reference:
Series X - Generation 1: http://www.hatteland-display.com/pdflink/inb100018-4.php
Series X - Generation 2: http://www.hatteland-display.com/pdflink/inb100018-6.php
The column "SCOM" is a reference and not part of the DDC/CI commands explained in the table below.
