3. Refer to the Reading Features table in chp. 7 for FOV calculation and minimum
distance requirements according to the base/lens combination used for your
application.
NOTE
Rapid Configuration of the Matrix 400™ reader can be made either through
the X-PRESS™ interface (steps 4-6) which requires no PC connection, or by
using the VisiSet™ Setup Wizard (steps 7-8). Select the procedure according
to your needs.
STEP 4 – FOCUS THE READER
Matrix 400™ provides a built-in tool called Blue Diamonds™ to aid focusing the reader. The
Blue Diamonds™ are accessed through the X-PRESS™ Interface.
1. Remove the lens cover in order to focus the reader.
2. Prepare the correct accessory lens for your application:
a. Loosen the two Locking Knobs on the lens.
b. Adjust the Focus ring to the "Far position" and the Diaphragm ring to the "F4" 1
number setting which is the preferred setting for installation.
3. Power the reader on. During the reader startup (reset or restart phase), all the LEDs blink
for one second. On the connector side of the reader near the cable, the “POWER ON”
LED (blue) indicates the reader is correctly powered.
4. Enter the Focus function by pressing and holding the X-PRESS™ push button until the
Focus LED is on.
5. Release the button to enter the Focus function. The Blue Diamonds™ turn on.
The procedure is as follows:
A) Adjust the Focus ring towards the "Near position" until
the Blue Diamonds™ are perfectly in focus, see
Figure 8.
At long focal distances a "skew" angle may cause a
noticeable difference in focus between the two
diamonds, in this case select the best possible focus
(both diamonds slightly out of focus).
Tighten the Focus Locking Knob.
B) Tighten the Diaphragm Locking Knob.

For far reading distances, the Diaphragm ring can be set to values between F2 and F4 to increase image lighting and Blue
Diamond™ visibility.
