PCN-1001 general description
The PCN-1001 is a compact and autonomous device based on non-contact stereoscopic vision technology. It has
been designed to count passengers entering and exiting the doorways of buses and trains, but can also be used
to count people as they enter or leave buildings or any other area with restricted access.
Figure 1. PCN-1001 front and rear
The stereoscopic cameras capture images of the area below the device (Detection area); the built-in high
luminosity infrared LED emitters allow for reliable operations in any type of lighting condition.
The PCN-1001 analyses any objects
moving within the Detection area,
considering height, shape and direction.
After determining if an object is a person
entering or leaving, the incoming or
outgoing values are stored accordingly,
along with time and date information.
This information is immediately available
via RS485 or downloaded at a later date
for analysis.

Adjustable front panel
horizontal
The PCN-1001 has to be installed so that the front panel is placed horizontal to the floor. To achieve this, the
angle between the front panel and the enclosure can be adjusted from 0° to 20° (up to 45° using an extender: the
extender also increases the protection of the rear side). Thanks to these characteristics the PCN-1001 can be
mounted in a variety of locations, even on non-horizontal surfaces.
to keep the PCN-1001
Many PCN-1001 systems can be installed in a vehicle, working stand-alone or networked together with a vehicle
server - the Control Unit - that can pre-process, store, and upload information from all the passenger counters.
To increase accuracy, door sensors can be used in combination with the PCN-1001.

PCN
Step 1: Find the best mounting location
To find the best location to install thePCN-1001, pay particular attention to the following considerations:
• Check the installation height
Ensure that the PCN-1001 installation height is suitable for your application, also taking into consideration the
local population’s average height. The ideal installation height is 225 cm.
The installation height of the PCN-1001 should allow sufficient distance between the front panel and the
average users’ height.
This should be done for the following reasons:
o If the PCN-1001 is installed too low, a high person passing under the PCN-1001 may hide another person
that is close to him.
o If the PCN-1001 is installed too low the detection area may not cover the entire width of the door.
o The velocity of a high person will appear to increase as its head gets closer to the cameras; this may
cause an inaccurate detection, and the person may not be counted correctly.
• Check the distance from the gate
The distance between the PCN-1001 and the gate should be large enough to prevent the inclusion of the
upper area of the gate’s frame.
The recommended distance between the PCN-1001 and the gate is about 50 cm.
• Check the gate width
Measure the width of the gate and evaluate:
o how many PCN-1001 devices you need to install
o if you need to use a Wide-gate configuration
• Check the centrality
Verify that you can place the PCN-1001 in the middle of the gate (if you are using the Wide-gate configuration,
the group of PCN-1001 devices has to be placed in the middle of the gate; refer also to “Number of PCN-1001
devices required” on page 27).
If not, the area in front of the gate may not be entirely seen by the cameras: if the detection area is shifted to
the right or to the left, some people may not been seen and therefore counting errors may occur
• Check that the front panel is horizontal
Verify that you can keep the front panel of the PCN-1001 horizontal (you can adjust the angle of the front
panel respect to the frame from 0° to 45°). If the front panel is not placed horizontal, this may cause counting
errors.
• Check the cameras coverage area
The PCN-1001 must be placed in a way that any person crossing the gate, also passes under the PCN-1001.
It is recommended to install the PCN-1001 with a maximum distance of 50 cm from the gate. If not, the area in
front of the gate may not be entirely seen by the cameras (the detection area will be too far from the gate)
• Check you have the required installation space
The PCN-1001 shape allows it to be mounted unobtrusively in the roof space over a gate or door.
You need to prepare a recess with the following dimensions:
o Height: 82.0 mm
o Width: 208.5 mm
o Depth: 41.5 (70.0 mm with optical panel at 45°)
The frame of the PCN-1001 has four mounting holes which allow the PCN-1001 to be secured using four M5
screws
You will have to provide all necessary fixing screws or bolts. This will depend on the location, material, and
any applicable regulations. We suggest using anti-vandalism screws to increase security.

The PCN-1001 field of view and the Detection area
The PCN’s field of view
The two PCN-1001 stereoscopic cameras have a specific field of view:
• The viewing angle relative to the long side of the front panel is about 70 degrees
• The viewing angle relative to the short side is about 55 degrees
The field of view can be seen as a pyramid with a rectangular base. The dimensions of the base will change
according to the PCN-1001 installation height and follow these formulas:
D = 2H tan(55/2) = 2H * 0.52
W = 2H tan(70/2) = 2H * 0.70
EXAMPLE:
If H = 225 cm then D = 234 cm and W = 315 cm

PCN
The Detection area
The Detection area is the zone where the PCN-1001 detects people.
The Detection area is contained in the cameras’ field of view, and can be seen as a truncated pyramid having two
parallel rectangular bases (a frustum).
• The height of the Detection area is always 100 cm, no matter which the PCN-1001 installation height is
• The Detection area can be shifted along its vertical axis.
The distance between the upper base of the Detection area and the front panel of the PCN-1001 can be
software-adjusted in two software-selectable ranges:
o 25 - 30 cm
o 31 - 40 cm
(See also ‘The “Distance Configuration” panel’ on page 61)
EXAMPLE:
If H = 225 cm and the “25-30 cm” range is selected the PCN-1001 will count - with the maximum precision -
people having heights from around 100 cm to around 200 cm. People outside this range (very tall or very short)
probably will not be detected correctly and will not be counted.
According to people’s average height you have to select the suitable PCN-1001 installation height and
the right Detection area distance.

The following picture gives you an example of frontal and lateral views of the installation.
When installing the PCN-1001, make sure that all the people crossing the gate are also crossing the Detection area.
If the detection area is shifted to the right or left, some people may not be seen and therefore counting errors may
occur.
The following picture gives you an example of this issue.

Number of PCN-1001 devices required
The number of PCN-1001 devices required depends on the width of the gate.
For gate widths up to 120 cm you need only one PCN-1001.
For gates wider than 120 cm you need to install a supplementary PCN-1001 for each additional 60 cm, and
connect the devices in Wide-gate configuration.
A maximum of 6 PCN-1001 devices can be connected together in wide-gate configuration. Please contact
Eurotech if you need more than this quantity.
Example
• To monitor gates up to 120 cm wide you will need one PCN-1001
• To monitor gates up to 180 cm wide you will need two PCN-1001 devices connected in Wide-gate
configuration
• To monitor gates up to 240 cm wide you will need three PCN-1001 devices connected in Wide-gate
configuration
NOTE:
When choosing how many counters you need to install, consider that a small tolerance is admitted (about 12 centimetres) with respect to the gate width.

Note about PCN-1001 devices connected in Wide-gate configuration
The figure below shows different PCN-1001 devices in Wide-gate configuration, all managed by the same Control
Unit (for example the Host PC).
The Control Unit sees each Wide-gate configuration as a single entity: Entity #1, Entity #2, …, Entity #N.
While the Master devices can be set with user-defined parameters the Slave devices have to remain with the
factory default parameters, as these are configured by the Master device upon power-up.

Step 4: Use WinClient to network PCN-1001 & Host PC
“WinClient” is a Graphical User Interface (GUI) that allows you to configure/debug the PCN-1001.
The WinClient software has been created to access and configure a single PCN-1001 at a time.
Before proceeding, make sure you have already installed WinClient on your Host PC. If not please refer to
“Install/update the software” on page 51 for further details.
After the PCN-1001 has been turned on and properly connected the WinClient has to detect it. In this way the
PCN-1001 and the Host PC will form a network. Follow these steps to detect the PCN-1001.
If the Host PC network has been setup correctly, when you open the WinClient you will see the next
available address in the IP Add dialog boxes.
For example if the Host PC Network IP address is [10.100.10.1] the Add dialog boxes will display
1. Select the "Connection" tab (A). Click the “Scan” button (B) and select the address of the PCN-1001 when it
appears (C)
2. Click the “Connect” button (D). Now the PCN-1001 is networked to the Host PC
NOTE:
If WinClient does not identify the IP address of the PCN-1001 automatically (e.g.: 10.100.10.100) you may
need to insert it manually

Step 4.1: Set the main parameters in the “Controls” tab
The “Controls” tab allows you to change the main settings of the PCN-1001 in order to obtain a good resolution
on windows 1, 2 & 3.
Any modifications to the settings will be automatically saved to the internal flash memory of the PCN-1001 and
takes immediately effect (a reset is not needed).
For further information about the “Controls” tab parameters refer to “The “Controls” tab” paragraph on page 61.
1: Set the “Date and Time settings”
Displays and allows you to set the system time and date.
Set date and time correctly!
This is extremely important especially in stand-alone installations where the user periodically downloads data via
the USB using the “Save Records” feature.
2: Set the “Distance Configuration”
Allows you to set the distance between the PCN-1001 and the upper border of the Detection area
Example:
If the installation height is 225-230 cm above the floor and you want to count people high between
one and two meters, you have to select the radio-button “25-30 cm”.
3: Set the “Light intensity”
Leave the checkbox unchecked.
For installations within buildings:
In these kinds of installation, it is assumed that the environment has a constant illumination.
It may be best to try several settings to find the one that best works for your individual requirements.
For on-board installations:
Slide the bar completely to the right to put the light intensity to maximum.
This will increase the counting accuracy even in installations where the environmental lighting conditions are
always changing and can suddenly vary.

enter the door, and verify that the correct counter In or Out is updated.
Changing the direction will reset the in/out counters.
5: Set the “Door kind”
When, on-board a transportation vehicle, a door is dedicated for entering only or exiting only, this option allows
the explicit declaration of the kind of door.
This declaration does not disable the incoming or outgoing counters but increases the sensitivity to people
traversing the detection area in a certain direction.
6: Set the “Door threshold”
Together with “Scene background” (point 7), “Door threshold” is one of the two most important
parameters that has to be set properly to increase accuracy.
During the tracking process, the two counters are incremented only if a person enters the detection area, crosses
the door threshold and then exits from the detection area on the opposite side.
By default, the threshold is placed at row 60 (the image height is 120 rows). The position of the line can be set
between row 30 and row 89.
In each visualization mode, except for “Tracking”, flagging the “View Threshold” checkbox will display the current
threshold (a white horizontal line) in Windows 1 and 2.
Guidelines to find the best threshold position:
• Place it in a way that any person entering or exiting has to cross it.
• Place it away from high reflective surfaces (i.e. the steps on a bus/train). If the detection area includes
also a portion outside the transportation vehicle, the door threshold should not be set outside.
• Place it away from door-opening mechanisms
• It should be placed in the middle of the detection area, which if the PCN-1001 has been installed
correctly above the door, should correspond to a central position of the “Door threshold” slide bar
If a door is intended to be used in a single direction, for example “in only” or “out only”, it may be useful to
move the threshold towards the exit edge of the detection area.

IMPORTANT NOTE:
If the background has altered
7: Use the “Scene background” button to acquire and store the background
Together with “Door threshold”, “Scene background” is the most important parameter that has to be
properly set to obtain a reliable counting process.
The acquisition and storage of the background is a fundamental and sensitive issue.
A bad background acquisition can seriously affect the counting process.
Acquire the background in the following circumstances:
• Once the PCN-1001 has been installed
• When the PCN-1001 has been relocated
•
Pay attention to the following issues:
• The background has to be taken with no foreign removable objects in the detection area
• The background has to be taken with doors open, especially if the doors would block the PCN-1001s’
field of view as frequently occurs within buses or trains
• Lighting of the detection area should be diffused as much as possible. No spot lighting (e.g. solar
reflections or strong lighting) should be present in the detection area during background acquisition
• Highly reflective, geometric structures situated on or near the floor, such as the metallic parts of a door
mechanism, which cause extreme patterns of light and darkness when illuminated by strong light (e.g.
direct sunlight or directional halogen lighting) could lead to flawed distance measurements. To avoid
performance degradation due to these effects the structures and any highly reflective surfaces should
be avoided as much as possible in the detection area
• Metallic or shiny objects (such as handles, bars, glass, etc.) should not cover a significant part of the
detection area. If this is not avoidable, the reflectivity of these items should be reduced by means of
non-reflective materials or modifying the “No Tracking Zone”
• If necessary, use the features of the “No Tracking Zone” panel in “The “Advanced (1/2)” tab” (page 73).
The “No Tracking Zone” feature allows you to define rectangular zones in the detection area where
tracking will not be performed. This feature can be used to mask surfaces that are very reflective or with
spot lighting

Suggested depth:
• Exclude as much as possible the area outside the transportation vehicle
• Verify that all the entrance area is detected properly. Make a person move under the PCN-1001s and
verify the correct detection
• The PCN-1001 can’t track more than 10
people at a time. In particularly crowded
conditions, i.e. on-board buses, 10 people
can be compressed in less than 1 m
detection area should be smaller. In these

70~90 cm
conditions a depth of 70~90 cm at floor level
is fine to guarantee a good tracking of
people.
Follow these steps to save the background:
1. Connect the PCN-1001 by pressing the “Connect” button
2. Select “8bit Disp. + median + FPN + ODC” in the drop-down list. In this way Windows 1 and 2 will display the
separated images as seen by the two cameras, subtracting the Fixed Pattern Noise (FPN) and the Optical
Distortion Correction (ODC). Window 3 will display the disparity map and a median filter will be applied for
reducing noise
3. Press the “►” button.
4. Ensure the doors of the gate are open!
5. Check that the PCN-1001 is correctly set up!
This means that in windows 1 and 2 you must see the scene as captured by the two cameras while in
window 3 the image has to be completely black or dark grey-scaled.
If for any reason it does not appear dark or any white spot appears, this will be recognised as one or
more objects present in the detection area. A background stored in these conditions may reduce
counting accuracy during the tracking process. Refer to the “Pay attention to the following issues:”
paragraph above for possible solutions
6. Press the “■” button
7. Select the “Controls” tab and click the “Scene Background” button. Ensure that window 3 remains
completely dark or dark grey-scaled until the process has completed. If not restart from step “5”
Wait for the progress bar to complete. When completed, the “Scene background Saved!” dialog box will be displayed.
NOTE:
Pay careful attention that the USB cable or any part of your body, especially feet, are not visible in the

Notes about images acquisition and FPS
During normal operations (default mode), the PCN-1001 acquires the images at a constant rate of approximately
60 Frames Per Second (FPS).
During configuration, the acquired images are transmitted to the Host PC for visualization. Depending on the Host
PCs characteristics and the USB connection, the FPS rate may differ. The value displayed in the bottom left
corner of the WinClient GUI is the current FPS rate detected by the Host PC. However the real FPS of the PCN1001 is not affected by these external factors and remains at 60 FPS.

The “Controls” tab
The “Controls” tab allows you to change the main settings of the PCN-1001 in order to obtain a good resolution
on windows 1, 2 & 3.
Any modifications to the settings will be automatically saved to the internal flash memory of the PCN-1001 and
takes immediately effect (a reset is not needed).
The “Date and Time settings” panel
Displays and allows you to set the system time and date.
Set date and time correctly!
This is extremely important especially in stand-alone installations where the user download periodically data via
USB using the “Save Records” feature.
The values displayed are updated when the system is connected. If after a successful connection the time and/or
date are not displayed correctly, enter the Regional Options within the Windows Control panel and set the time
separator to “.” And the date separator to “/”; after doing so reconnect to the PCN-1001 and verify that the time
and date are correctly displayed.
If the PCN-1001 remains without power for more than seven days, the current time and date information will be
lost, and therefore will need to be corrected.
The “Distance Configuration” panel
Allows you to set the distance between the PCN-1001 and the upper border of the detection area.
Example:
If the installation height is 230 cm above the floor and you want to count people high between one
and two meters, you have to select the radio-button “25-30 cm”.
The “Light intensity” panel
The light intensity of LED indicators can be adjusted automatically or manually by the using this slider and
Checkbox.
Flagging the checkbox will make the PCN-1001 automatically adjust the LED intensity according to the
environmental lighting conditions.

For installations within buildings:
In these kinds of installation, it is assumed that the environment has a constant illumination.
The right light intensity has to be found experimentally.
For on-board installations:
Slide the bar completely to the right, and put the light intensity to the maximum.
This will increase the counting accuracy even in installations where the environmental lighting conditions are
always changing and can vary suddenly.
The “In/Out direction” panel
Be careful to set the direction for incoming and outgoing people in the right way, paying attention that the arrows
refer to the motion of people as displayed on the WinClient interface.
Changing the direction will reset the in/out counters.
The “Door kind” panel
When, on-board a transportation vehicle, a door is dedicated to the entering only or the exiting only of
passengers, this option allows the explicit declaration of the kind of door.
This declaration does not disable the income counting in a door declared as “one-way out” but decrease the
erroneous counting of incoming people due to reflections or due to atypical behaviour of passengers (a
passenger that was intended to go out, invert his direction and returns back) in the proximity of the open door.
The “Door threshold” panel
This is an important parameter that has to be properly set to obtain a reliable counting process.
During the tracking process, the two counters are incremented only if a person enters the detection area, crosses
the door threshold and then exits from the detection area on the opposite side.
By default, the threshold is placed at row 60 (the image height is 120 rows). The position of the threshold line can
be set between row 30 and row 89.
In each visualization mode, except for “Tracking”, flagging the “View Threshold” checkbox will display the current
threshold (a white horizontal line) in Windows 1 and 2.

Guidelines to find the best threshold position:
• Place it in a way that any person entering or exiting have to cross it.
• Place it away from high reflective surfaces (i.e. the steps on a bus/train). If the detection area includes
also a portion outside the transportation vehicle, the door threshold should not be set outside.
• Place it away from door-opening mechanisms
• It should be placed in the middle of the detection area, which if the PCN-1001 has been installed
correctly above the door, should correspond to a central position of the “Door threshold” slide bar
If a door is intended to be used in a single direction, for example “in only” or “out only”, it may be useful to
move the threshold towards the exit edge of the detection area.
The “Data records” panel
The Incoming & Outgoing counters along with Time & Date information is saved immediately by the PCN-1001;
every sixty seconds these values are appended to a text log file within the flash memory of PCN-1001.
Depending on the Optocoupled I/O functions selected (see the ‘Optocoupled I/O functions panel’ paragraph on
page 67) the information written to the log file will be different.
The following paragraphs describe the available log file formats.

Saving the records of the log file
By clicking the “Save records” button you will be able to download the log file as text. You will be given the option
to “Save As” – “filename.txt”.
The PCN-1001 can record a maximum of 300,000 log lines.
When the PCN-1001 exceed the amount of 299,999 log lines the internal software will overwrite the oldest
block of 30,000 lines with the new data, leaving the remaining 30,000 x 9 lines already recorded.
In this case the system will continue to cancel and rewrite each successive block of 30,000 lines
It is possible to use the Mini USB 1.1 client connector located on the front side of the PCN-1001 in order to
transfer data (i.e. to a Host PC).

• Once the PCN-1001 has been installed
• When the PCN-1001 has been relocated
•
Pay attention to the following issues:
• The background has to be taken with no foreign removable objects in the detection area
• The background has to be taken with doors open, especially if the doors would block the PCN-1001s’
field of view as frequently occurs within buses or trains
• Lighting of the detection area should be diffused as much as possible. No spot lighting (e.g. solar
reflections or strong lighting) should be present in the detection area during background acquisition
• Highly reflective, geometric structures situated on or near the floor, such as the metallic parts for door
mechanisms, which cause extreme patterns of light and darkness when illuminated by strong light (e.g.
direct sunlight or directional halogen lighting) could lead to flawed distance measurements. To avoid
performance degradation due to these effects the structures and any high reflective surface should be
avoided as much as possible in the detection area
• Metallic or shiny objects (such as handles, bars, glass, etc.) should not cover a significant part of the
detection area. If this is not avoidable, the reflectivity of these items should be reduced by means of
non-reflective materials or modifying the “No Tracking Zone”.
Follow these steps to save the background:
1. Connect the PCN-1001 by pressing the “Connect” button
2. Select “8bit Disp. + median + FPN + ODC” in the drop-down list. In this way Windows 1 and 2 will display the
separated images as seen by the two cameras, subtracting the Fixed Pattern Noise (FPN) and the Optical
Distortion Correction (ODC). Window 3 will display the disparity map and a median filter will be applied for
reducing noise
3. Ensure the doors of the gate are open!

The “Optocoupled I/O test” panel
The two outputs, GPO1 and GPO2, (GPO means General Purpose Output) have the purpose to react when a
person is counted:
• GPO1: By default is associated to incoming people
• GPO2: By default is associated to outgoing people
The optocoupled output electronics behave as low-side switches normally closed.
When the PCN-1001 detects a person, one of the two outputs (depending on the direction of the person) turns its
status to open for a period of “GPO-Open-Time” milliseconds.
The GPO-Open-Time (GPOOT) can be configured inserting a value (from 8 to 1020 milliseconds) in the two
GPO1 and GPO2 open time fields on the “Optocoupled I/O test” panels.
If two people walk in the same direction under the PCN-1001, the first signal will be immediately sent to the
appropriate output, the second will be queued for (2 x GPOOT) milliseconds.
In the Wide-Gate configuration the GPO1 used will be the one of the first PCN-1001.
The GPO2 will be the one of the last PCN-1001. In any case, both the GPO-Open-Times have to be set
connecting the first PCN-1001.
GPI1 Test / GPI2 Test
Follow these steps to test the inputs:
1. In the drop-down lists of the “Optocoupled I/O functions” panel select the option “Test” for either GPI1 or
GPI2
2. Press the “Set” button
3. Press either “GPI1 Test” or “GPI2 Test” button. If a rising edge is received on GPI1 or GPI2, the
corresponding grey rectangle will turn to white. If a falling edge is received it will turn to grey
NOTE:
The “Test” functions are only available via Socket API, not via RS485.
GPO1 Test / GPO2 Test
In order to test the outputs press the “GPO1 Test” or “GPO2 Test” button. The GPOOT value will be set to the
nearest multiple of four lower than or equal to the inserted value.

Notes about the Digital I/O interface
The PCN-1001 can be interfaced and triggered by means of two general-purpose inputs and two general-purpose
outputs. For example, the general-purpose digital I/O interface can be used to detect a doors status (open or
closed).
In this case the logic to follow is:
0 Door closed
1 Door open
The counters will be activated when the door
status becomes 1 (Open).
The general-purpose I/Os are 1 kV isolated
and are available on the M1 connector.
They allow for a direct connection to industrial equipment with an isolation of 3750 V
In the Wide-gate configuration the door status input has to be connected to the M1 connector of the first PCN-
1001, using GPI1. For further information refer to the ‘Optocoupled I/O functions panel’ paragraph on page 67
and to the Note: ‘How the threshold works when using digital inputs’ on page 47.
The Output Block
The figure below shows the electrical schematics of the output block. The labels on the right side refer to the M1
and M2 connectors, while the left side of the picture refers to the internal processing part of the system.
The Output Block behaves as a low-side switch. The load connected to the low-side switch can draw current
either from an external power source or from the Digital OUT V+ referred to the Digital OUT GND.

“Time Background” panel
The “Time Background” is an algorithm that can be used after the “Scene background” procedure. It allows you to
dynamically acquire the background in order to manage intense light variations of the detection area or manage
static objects that may be introduced in the detection area after its first acquisition during the installation, all
conditions that may affect the scene background.
The “Time Background” feature has been specifically developed for building installations.
If the PCN-1001 is installed on-board a transportation vehicle it is strongly recommended to disable
the Time background by setting to “0” the value of the “Time bkg” parameter.
This because the time when the door will be open is not predictable. If the acquisition of the
background starts while the door is opening there would be a discrete number of false negatives.
The value of the “Time bkg” parameter indicates how many minutes should pass before automatically executing a
new background acquisition; this happens only if during this period of time the image changed a number of pixels
higher than the valued indicated by the “Static Threshold” parameter. The maximum “Static Threshold” value is
19200 pixels.
NOTE:
The “Time Background” algorithm foresees that any person stands in the detection area for less than the
amount of time (in minutes) set by “Time bkg”
Typical values are:
• “Time bkg” = 2-5 minutes (Default set is 0 and means disabled)
• “Static Threshold” = 1500-3500 pixels (Default set is 2500)
The “Time Background” algorithm is enabled giving to “Time bkg” a value higher than 0.
Use the command “timebkg” followed by the number of minutes (unsigned char) in order to set “Time bkg”
Use the command “staticth” followed by the threshold value (number of pixels (int)) in order to set “Static
Threshold”.

Introduction
Thanks to its RS485 ports, the PCN-1001 allows you to take advantage of all the benefits of an RS485 network,
including the possibility of connecting multiple devices – up to 32 at the same time – and perform
communications over long distances even in electrically noisy environments.
RS485 communications are based on a master/slave configuration:
• The master (a Host PC such as a laptop or, in a real situation, the main on-board computer that acts as
the Control Unit, for example a Eurotech DuraCOR system) begins communications by sending a
message to the slave devices
• The slave devices (the PCN-1001 devices) analyse the message, execute a command (if required) and
transmit the answer to the master.
The “RS485_GUI” is a program that, once installed on the Host PC, can be used to simulate a real RS485
connection.
Warning:
The parameters of the serial port on the Host PC and PCN-1001 must be equal (see ‘Configuring the RS485
port of the PCN-1001’ on page 82)
The PCN-1001 system does not include any line termination resistor, nor any fail safe bias resistors.
The two ends of the RS485 bus should include a termination resistor connected across the Data + and Data
– wires. Furthermore, one end of the RS485 bus should include pull-up or pull-down resistors to ensure a

Notes about the RS485 serial bus for development purposes
• The same “Multifunction cable” (found in the CBL-1001-00 Cable Kit) you are using to supply power to the
PCN-1001, also allows you to connect the PCN-1001 to the RS485 port of the Host PC by using Cn4.
• Personal Computers generally do not have a RS485 port. You can use the “703704001SL Adapter” (an
element of the CBL-1001-00 Cable Kit) to connect Cn4 of the Multifunction Cable with the USB port of the
Host PC. The 703704001SL Adapter also integrates one termination resistors (120 Ohm) and two fail safe
resistors (560 Ohm). Refer to “CBL-1001-00 cable kit” on page 100 before attempting to use the
703704001SL Adapter.

Example of RS485 network
Several PCN-1001 devices can be connected in a Multi-drop RS485 two-wire half-duplex setup, see the diagram
below. In this configuration:
• You need a Host PC that acts as Master device, manages the RS485 network, and has ID number = 1
• Each one of the PCN-1001 devices must have same values for Baud Rate, Data Bits, Parity and Stop Bits,
but different ID number, starting form 2.
The Host PC starts the communication and includes the address of the target PCN-1001 within the SNP (Small
Network Protocol, see the paragraph ‘The communication protocol’ on page 87).
All the PCN-1001 devices receive the command but only the target PCN-1001 will respond.
Note:
In Wide-Gate Configuration the Host PC sees only the first PCN-1001 of each group of counters in and the
address has to be assigned only to this one.

The file transfer progressing is displayed in the log view as shown as follows:
No other operation is allowed during file transfer.
When transfer finishes a proper message will be shown in the log view and the user will be allowed to perform
other operations.
The “Stop” button stops the transfer and interrupts the update.
Notice that even if during the file transfer some packets are lost the protocol guarantees a successful
transmission by sending again the lost packets. If more than 10 consecutive packets are lost the application will
stop the file transfer and an error message will be displayed in the log view.

The communication protocol
SNP (Small Network Protocol) is the communication protocol used in the RS485 connection.
The packet format contains the addresses of both the sender and recipient and the number of packets to be sent
along with the current packet number.
Bit stuffing is not used because, when the length of data field is stated, all values can be sent in the data field.
The maximum length of the data field is MAX_DATA_LENGTH = 1024 bytes.
Address of sender
States the length of the data field
LSB (Least Significant Byte) is to be sent first
(both fields included) with an initial value of -1.
LSB is to be sent first
Remember that there is only one master on the bus, while all others are slaves. When the master has sent a
message to a slave, an answer from the slave is expected. A slave cannot send anything to a master without
being asked. It is possible to send to all slaves at a time (broadcast), which means that slaves do not return an
answer and that messages are not retransmitted.

Systems
Each message between Master and Slave is made in the following format:
Source: Address of the device transmitting the message
Destination: Address of the target device
TotalPacketNumber: Quantity of Packets to be sent
PacketNumber: The number of the current packet being sent
DataLength: Length of the data in this Packet [0x01 to 0xFE or MAX]
Therefore, as we can see from the examples on the previous pages, a message may take this form:
[0x01, 0x02, 3, 2, MAX]
In this case Node “0x01” is sending a message to Node “0x02”; this is package 2 of 3, and is MAX (255)
characters long. Whereas:
[0x02, 0x01, 1, 1, 2]
would be Node “0x02” is sending a message to Node “0x01”; this is package 1 of 1, and is 2 characters long.
The following message would be a Broadcast message:
[0xFF, 1, 1, 1, 2]
This is indicated by the 0xFF, which means all Slave devices will act upon the message, however, no reply will be
sent by any of the Slave devices.
The DATA field
All the messages exchanged between the Master and the Slave units have to be encapsulated in the SNP
transmission.
The command to send is contained in the Data field of the SNP protocol.
All the commands are formed by: the Command string, the String terminator, and some values (Value 1, Value 2,
…). Each value can be a number (1, 2 or 4 bytes long ) or a string.
The Data field maximum length is contained in the MAX_DATA_LENGTH

Note for mounting the front panel with angles from 20° up to 45°
Please contact Eurotech to use this configuration in order to properly configure the software parameters of the
PCN-1001.
To use front panel angles between 20° and 45°, it is recommended to mount the PCN-1001 Extender to better
protect the rear connections. It is also recommended to install any cabling before mounting the extender, this will
give easier access to M1 and M2.
Use the two M3 x 6 hexagonal head screws (and the two split washers) provided to fix it to the PCN-1001. A
hexagonal 2 mm (3/32”) key/driver is required.
This is the procedure for mounting the PCN-1001 Extender:
1. Place the Extender onto the rear of the PCN-1001; ensure that the two locating tabs (A and B) are correctly
aligned
2. Ensure that the holes on the Extender and on the PCN-1001 are correctly aligned
3. Insert the two washers and the two M3 screws into the holes and firmly tighten them.
-1001_UserMan_En_4.0
IMPORTANT NOTE!
Once the PCN-1001 is installed, the angle of the front panel cannot be modified and the rear
connectors cannot be accessed without removing the entire device from the ceiling.
