1.1 STS400™ - SOLUTION FOR TIRES SORTING
STS400™, which means Solution for Tires Sorting, is a solution designed to be easily
integrated into a sorting system for reading barcodes on the tires.
STS400-005 Reading Station
Tire Sorting Station
The solution, made up of an array of Matrix 410™ ATS readers has been studied to be a pre-
mounted, pre-configured system entirely validated at the factory, in order to be quickly and
easily installed by any technician.
The STS400™ provides easy maintenance with a smart solution for fast replacement of any
single Matrix 410™ ATS reader.
There are a number of STS400™ models which can be chosen to satisfy all the customer
needs in terms of: maximum code resolution, conveyor width and depth of field.
Multiple Matrix 410™ ATS readers are combined in an array designed to cover a fixed
conveyor or belt width at a fixed range of distances
The readers are part of a Master/Slave high speed ID-NET™ network
The Master collects the data from the Slaves, handles I/O and communicates with the
host
All external connections take place through the CBX500 ATS-001 connection box
Two photoelectric sensors are included for triggering the reading phase. Alternatively the
reading phase can be controlled by Host commands from the serial, Ethernet IP or
Fieldbus interfaces.

1.2 TERMINOLOGY
The manual will refer to some technical terms when explaining how to choose and install the
STS400™. The following table will list the most used.
Code Resolution
Code Resolution is the width of the narrowest
module (element) in a barcode, usually
expressed in millimeters. It is also commonly
expressed in mils, (thousandths of an inch).
DOF
DOF stands for Depth Of Field and it
indicates the range (distance from the reader)
where the barcode can be read.
FOV
FOV stands for Field Of View and
describes the reading area at a given
reading distance within the DOF.
Horizontal FOV defines the reading
width of the STS400™ across the
conveyor. Vertical FOV defines the
reading length of the STS400™ parallel
to the conveyor.
The guaranteed reading volume is
defined as:
FOVHmin x FOVVmin x DOF
on Code 128 codes from the Datalogic
Test Chart.
Tire Terminology
Width
It is the widest point from sidewall to sidewall of
the tire.
Height
It is the difference from the external to the
internal diameter of the tire.
Diameter
It is the internal diameter of the tire which will fit
the car wheel rim.
Bead
It is the part of the tire which contacts the car
wheel rim. The barcode is usually applied here.

1.3 STS400™ FEASIBILITY REQUIREMENTS
In order to make the best STS400™ solution choice which fits the application needs, some
basic information is required.
Highest Application Code Resolution: this data is fundamental for choosing the STS400™
model. This information must be the minimum barcode module among all the barcodes to be
read in the application.
STS400™ is supplied for two nominal resolutions:
High Resolution, resolution between 0.25 mm (10 mils) and 0.30 mm (12 mils)
Standard Resolution, resolution lower than or equal to 0.30 mm (12 mils)
Note: If the Resolution is higher than 0.25 mm (smaller module width), please contact your
local Datalogic representative.
Maximum Application DOF: this data corresponds to the difference between the maximum
width (Wmax) and the minimum width (Wmin) among all the tires to be sorted:
Maximum
Application
DOF
W min
W max
W max W minMaximum
Application
DOF
This information can be achieved by physically measuring the width of all tires to be sorted,
and looking for the two limits.
More easily, this information can be achieved by collecting all the tires size information
printed on them. (See par. 1.3.1).
STS400™ satisfies different ranges of DOF according to the code resolution and reading
station application type:

Conveyor Operating Width: This is the effective operative width where the tires can run:
Operating
Width
Maximum Application FOV: This data is the maximum reading width where a barcode can
be found by the STS400™.
Because the barcode is located on or next to the Bead of the tire, the barcode will never be
found at the edges of the Conveyor Operating Width. The Maximum Application FOV
therefore can always be less than the Conveyor Operating Width:
FOV
Operating Width
The figure above shows a sectional view of the tires in order to better understand the
difference between the Maximum Application FOV and the Conveyor Operating Width.
The Maximum Application FOV can be calculated with the following formula:
FOV = Operating Width – 2 * (Minimum Tire Height – Barcode Position Margin)
The Barcode Position Margin takes into account the distance from the Bead where the
barcode could be applied.
Maximum Conveyor Speed: The STS400™ with factory default configuration can support
speeds up to 1 m/s (196.85 fpm, 60 m/min).
NOTE: Higher speeds can be obtained by modifying the configuration,
please contact your local Datalogic representative for feasibility.

1.3.1 Extracting Tire Size From Tire Sidewall Markings
The best way to find out your tire size is to actually look at the tire sidewall. As you can see in
the figure below, there is generally a lot of different information on the tire; however, for our
purpose, we just need 3 pieces of information:
1. Tire Width: the “215” designation
states the Width of the tire in
millimeters at the widest point
from sidewall to sidewall when
mounted on the correct wheel.
2. Tire Height: the “65” designation
is the Aspect Ratio. This ratio is
calculated by dividing the section
Height by the Width. Therefore
the tire height is calculated as:
Height = Ratio * Width / 100
3. Tire Diameter: the “15”
designation is the Diameter of the
wheel rim in inches. This is the
exact size that the tire will fit.
Once the whole list of the nominal values of all the tires has been collected, it is very easy to
understand the application needs, and chose the correct STS400™ model. See the following
sample table:
W [mm] R [%] D [Inch] H [mm] Dint [mm] Dext [mm]
Tire 1 120 70 12 84 304.8 472.8
Tire 2 175 65 14 114 355.6 583.1
Tire 3 185 55 14 102 355.6 559.1
Tire 4 205 60 15 123 381.0 627.0
Tire 5 205 65 15 133 381.0 647.5
Tire 6 190 50 17 95 431.8 621.8
Tire 7 100 100 18 100 457.2 657.2
Tire 8 275 45 18 124 457.2 704.7
Tire 9 275 45 20 124 508.0 755.5
Minimum [mm] 100.0 84.0
Maximum [mm] 275.0 133.3 508.0 755.5
DOF Required [mm] 175.0
Note: Dext is the external tire diameter. Even if this data is not used for the best choice of the
STS400™, the above table shows it. It can be calculated as: Dext = Dint + (2 * H).

Single Matrix 410™ ATS-xxx models are used as stand alone readers having the same
characteristics as the relative application type STS400™ models. They are also used as
replacement readers for the relative STS400™ stations.
The Reading Features of the various STS400™ models are given in chapter 5.
1.5 POWER REQUIREMENTS
The STS400™ solution kit doesn’t include a power supply unit, which has to be ordered
separately. The maximum power required depends on the model.
Power is supplied to the system through its connection box CBX500 ATS. In the case of
STS400-10x models, in addition to system power through the CBX500 ATS, the illuminator is
supplied directly through the QL100 connectors.
The following table indicates the compatible power supply to use according to the STS400™
model. The supply current consumption values are given considering the default parameter

2 INSTALLATION
2.1 STS400™ SUPPORTING FRAME
STS400™ has been optimized to be mounted on aluminum profiles. A frame made up of
aluminum profiles allows the easiest and fastest mounting, and in most cases is the best
choice.
However, STS400™ can also be mounted on different supports like a fixed column.
Because it is impossible to supply a standard frame which fits all the infinite needs of the
customers, it must be designed during the feasibility study of the specific application.
When studying a frame, it is suggested to design it with some safe margins for adjustment
because of unforeseen changes at installation time like obstacles or different height
requirements. Even if the STS400™ height can be calculated in advance, it is suggested to
leave freedom on all three axes for fine adjustment in the field. The following figure shows
how this can be achieved and is the type suggested by Datalogic.
In this sample frame the STS400™ can be moved up-down, backward-forward, and left-right:
The length of the aluminum profiles has to be dimensioned according to the following
constraints:
physical conveyor width
conveyor height from floor to the tire reading plane
Application DOF
STS400™ model
mimimum width (Wmin) of the tires
The next three paragraphs suggest the formulas to be used for the frame dimensioning.

2.1.1 Frame Width
The frame Width has to be calculated according to the distances shown in the following
figure:
STS Main Plate Dimensions
STS400-xx7 and -xx8 = 1065 mm
(41.9 in)
STS400-xx4 to -xx6 = 785 mm
(30.9 in)
STS Main Plate
Conveyor Width
Max Side Room
Safe Safe
Max Side Room
W
The Safe clearance between the frame and the conveyor sides has to be chosen according
to the Maximum Side Room available. It is suggested to always keep at least of 200 mm of
Safe clearance.
The length of the frame profiles W can be calculated in 2 ways, according to whether the
STS400™ main plate is wider than the conveyor Conveyor Width or not:
If Conveyor Width > STS Main Plate then: W = Conveyor Width + (2 * Safe Margin)
If Conveyor Width STS Main Plate then: W = STS Main Plate + (2 * Safe Margin)
Note: The STS400-xx7 models require a 70 or 55 mm shift to center the FOV over the
conveyor and therefore must be accounted for in the frame width calculation.
2.1.2 Frame Length
It is suggested to keep at least 500 mm of Safe clearance for the frame Length (L). This
allows good frame stability and freedom for moving both the reading phase sensor(s) and the
STS400™, forward or backward:
