1. APPLICATION
The PD10 converter is a device which transmits data from the USB
interface to the RS-485 industrial interface. USB interface, as the first,
is destined to communicate with the device having a USB Host port,
which is the most frequently a PC computer.
The RS-485 interface, as the second, is destined to communicate with
devices in the object side. The maximal baud rate is 1 Mb/s. This baud
rate depends on the RS-485 cable length. The converter does not inter-
fere in the structure of transmitted data and is compatible with several
industrial communication protocols, e.g. Modbus RTU, Modbus ASCII,
a.s.l. In order to protect devices at both sides of interfaces, a galvanic
separation is applied.
A program controller of the virtual serial port COM for the computer PC
is added to the set.
It allows to exchange data by master programs with industrial objects
through the P10 converter.
2. CONVERTER SET
The PD10 converter set includes:
nPD10 converter 1 pc
nUser’s manual 1 pc
nGuarantee card 1 pc
nUSB cable of 1.8 m long 1 pc
nCD with drivers 1 pc
When unpacking the converter, please check the set completeness
and whether the type and execution code on the data plate correspond
to the order code.

3. CONVERTER INSTALLATION
3.1 Converter installation and operational safety
The converter is a portable device supplied from the USB bus. Dimen-
sions of the converter are presented on the fig. 1.
Fig.1 Overall dimensions of the PD10 converter
In the safety service scope, the PD10 converter meets to requirements
of the EN 61010-1 standard.
Observations concerning the operational safety
nAll operations concerning transport, installation, and commissioning
as well as maintenance, must be carried out by qualified, skilled
personnel, and national regulations for the prevention of accidents
must be observed.
nBefore switching converter on, one must check the correctness of
connection to the network.
nDo not connect the converter to the network through an
autotransformer.
nBefore removing the converter housing, one must switch the
supply off and disconnect measuring circuits.
nThe removal of the meter housing during the guarantee contract
period may cause its cancellation.
nThe PD10 converter is destined to be installed and used in
industrial electromagnetic environment conditions.

7
nOne must remember that in the building installation a switch or a
circuit-breaker should be installed. This switch should be located
near the device, easy accessible by the operator, and suitably
marked.
3.2. Description of converter leads
Markings of individual leads are shown on the fig. 2
Fig. 2 External leads of the PD10 converter
External signals must be connected acc. to tables 1 and 2, in which the
assignment of individual PD10 converter leads are described.
There are two diodes on the frontal plate:
Green (RxD) – signals the reception of data via RS-485.
Yellow (TxD) – signals the transmission of data via RS-485.

3.3. Installation of the COM port for Windows
The PD10 converter makes use of FTDIBUS Driver and FTDIPORT
Driver, licensed by the Future Technology Devices International Ltd
company. This software creates in the system a device of Universal
Serial Bus - The Converter USB-RS485 of PD10 type and connected
to it, the virtual COM port, named USB-RS485 Converter Port Com of
PD10 type.
The controller installation in the Windows system causes the addition
of a successive COM serial port to the list of ports serviced by the
operating system.
3.4. Installation of COM port controllers on the
computer
After connecting the connector to the USB port, the operating system
informs about the appearance of a new device by means of a message
presented on the fig. 4.
The creator to find the new hardware of the Universal Serial Bus . One
must operate acc. to the creator, choosing the installation from the in-
dicated location and giving the path to controllers being in the added
CD.

Controllers are compatible with systems: Windows 2000, Windows XP,
Windows Vista, Windows Server 2003 (x86 and x64).
When installing controllers, information about the lack of controller digi-
tal signature can occur. One must ignore this information and further
continue the installation.
Fig. 3 Systemic message about the detection of the PD10 converter
through the System
After the creator closure, the system immediately detects the next de-
vice – USB Serial Port (fig. 4). The creator to find new hardware will be
started again.

After a successful termination of the installation, the system informs
about the installation of the new hardware (fig.5) In the Device Mana-
ger, two new devices appear:
- Converter USB—RS485 of P10 type and Port COM named: Conver-
ter USB-RS485 of PD10 type, acc. the fig. 6.

3.5. Example of Lumel Heat and Lumel 3000
configuration to co-operate wit PD10
Lumel Heat and Lumel Energy systems communicate with industrial
devices by means of COM serial ports.
After the installation of additional virtual COM serial ports, one can
appeal to them in systems of Lumel series. Then, one must introduce
or modify supervising appeals to added communication ports in new or
existing applications or system configurations.
4. OPERATION DESCRIPTION
The RS-485 standard enables the data exchange of half duplex type.
That means that they can be in the same time transmitted or received.
PD10 converters can work with a maximal baud rate up to 1 Mb/s depen-
ding on the line length (e.g. 9600 kb/s on lines up to 1000 m long, 1 Mb/s
on lines up to 10 m long). At lines over 800 m, between lines A and B of
the RS-485 interface, one must use terminators (resistors) on ends of the
bus. The terminator value should be adapted to the application.
In the environment with unknown interference
level it is recommended to observe following
principles:
nConnections of communication interface circuits must be
conducted individually by twisted wires in a screen.
nApply the general principle that wires (group of wires)
leading different signals should be led in the possible
farthest distance between them (not less than 50 cm) and
the crossing of such group of wires should be made at right
angle.
nThe device does not fulfil requirements concerning the
electromagnetic compatibility in residential environment
