1. Introduction
1.1 Product Description
When updating images with high contrast and high density (such as sonar or dense
information data) the LCD’s brightness varies with the rate of updating. This
luminance variation, referred to as ‘LCD Flicker’, can cause eye-fatigue and affect the
interpretation of the displayed data. With the ISIS LFC kit here described, a unique set
of algorithms is integrated in the ISIS display that reside in the hardware interface of
the display (between the graphics generator and the LCD). This feature compensates
for LCD Flicker without affecting the displayed data.
Figure 1-1 shows a preferred calibration set-up.
Figure 1-2 shows the differences between an ISIS display without and with LFC.

2.2 Start-up and use
2.2.1Software upload
Although software upload is described here below, it is not necessary when
installing a kit as the software is already loaded in it.
1. Connect the remote port (J11) with a null-modem cable to the COM port of your PC.
Note that the upload won’t work via the Keypad port!
2. Start up softloader and configure the terminal settings for 115200 baud, no parity and
the upload settings for 115200 baud, binary mode and auto connect disabled.
3. Using keypad or OSD, navigate to the LFC advanced menu. This is a submenu of the
Input Boards menu which is a submenu of the Administrator menu (UNIF button
on the keypad). See Advanced LFC menu (Administrator Menus) for more details. On
the last page of the LFC advanced menu select Upload: to start the upload.
The keypad/OSD should say Starting… and on the terminal the following text should
appear:
Sending signature
Waiting for INTEL HEX data record …
4. When Waiting for INTEL HEX data record has appeared or when the keypad (or OSD)
says 0 lines received the upload can be started. In softloader push the Upload button
and select the new .hex file to start the upload.
When the communication with the LFC hardware could not be established the upload
fails. In that case Upload failed is shown on keypad/OSD.
5. The keypad/OSD should now display how many lines there were received.
6. After the upload of data is done the data is programmed into the flash, indicated as
Programming flash … on the keypad/OSD.
7. When the programming is done the keypad/OSD will show Upload finished when the
programming was successful and Upload failed when the programming failed. This will
also be printed on the terminal in softloader.
2.2.2User Interface
LFC has to be “installed” before it can be used. See “LFC Install” further.
2.2.2.1 Enabling/disabling LFC (Administrator Menus)

2.2.2.3 LFC install
In order to be able to use LFC, LFC should be ‘installed’ first.
The following “LFC install” procedure should be carried out with utmost
precision. Entering a wrong command may render the display unserviceable
and requires a factory return.
Items needed:
•Firmware Download Tool (FDT) software;
•a KP/Upload cable Z3498894 or equivalent;
•a PC.
The needed items are included in the Barco ISIS Service Kit K5030070.
The Z3498894 cable pinning is also described here below.
1. Connect the COM port of the PC directly with the REMOTE IN (J11) PIB connector with
a 3-wire crossed KP/Upload cable Z3498894.This special cable is defined as follows.
Only pins 2, 3 and 5 are used. Pin 2 and 3 are twisted.
