7.2 GT11
7.2.1 Functions of GT11
Using Matsushita protocol “MEWTOOL”, you can display and change the settings of the LightPixAE20 on GT11, or
display reading data or judgment results on GT11.
You can use it mainly for controlling the LightPixAE20 or checking reading data while being accessible each
other, but the GT11 can communicate with LightPixAE20 only if versions and setting values of GT11 and
GTWIN meet the following conditions:
GTWIN version: 2.62 or later
GT firmware version: 1.020 or later. If GT11 version is before 1.020, update the software to 1.020 or
later following the steps below:
Select “NAiS Terminal “ > ” GTWIN “ > “Tools “ > "GT Ver_UP" from the Windows start menu.
Set the communication conditions for the GT configuration as follows:
Retry: 255 times and Waiting time: 0 sec
Since the LightPixAE20 does not receive any serial (RS-232C) commands while capturing images, it may
ignore transmissions from the GT11. Therefore, increase the retry time up to the upper limit and set waiting
time to 0 sec. so that the GT11 can execute retries one after another (in this case, the device executes retries
every about 50 ms). But, even if the waiting time is set to 0 sec., the LightPixAE20 cannot receive all
transmission data but receive the data once every five retries
Only the firmware of GT11 version 1.020 or later executes retries every about 50ms even if the
waiting time is set to 0 sec, so any other display unit than GT11 cannot be used (as of Jan., 2005).
