1. APPLICATION
The PD8 converter allows to transmit data to the master devices through the
computer network o Ethernet type, to devices equipped with the RS-485 inter ace.
The converter is available in two versions concerning its operation manner: Real-
Port network service and serial bridge with UDP protocol.
In the version nr 1, the PC computer with the Ethernet network card is the connected
master device. In the version nr 2, the converter co-operates with the device with the
master unction and the RS-485 serial inter ace. The version nr 1 o the PD8 conver-
ter requires the installation o a programmed controller o the virtual serial port on the
PC computer with the Windows system.
This controller ensures to present-days master systems, e.g. LUMEL-HEAT and
LUMEL-ENERGY systems, the possibility to transmit data between devices with
RS-485 inter ace, through the Ethernet network, thanks the use o converters o
PD8 type (Fig. 1). The converter used in this manner enables to co-operate only with
one master computer in the giving moment.
In case o using PD8 or servicing MODBUS and LUMBUS industrial protocols - its
correct co-operation with master systems on a PC depends on their built-in
mechanisms to control break-time intervals between received transmission
characters. When using PD8 in the version nr 2, one can develop the RS-485 bus
with successive segments by means o additional PD8 converters and the local
Ethernet network.
The suitable con iguration, at least o one pair o converters, allows to obtain their
operation in the serial bridge mode (Fig. 3.). The con iguration o their operation
is also possible in the mode one-to-several ( in the shape o a set including
maximally 65 converters - Fig. 4.)
The version nr 2 operates in the local Ethernet network servicing the UDP
datagram protocol.
2. PD8 CONVERTER SET
The converter set is composed o :
- PD8 converter 1 pc
- PD8 users manual 1 pc
- warranty card 1 pc
- mini CD with so tware 1 pc
When unpacking the converter, please check the delivery completeness and
whether the type and version code on the data plate correspond to the order.

3. INSTALLATION AND BASIC SAFETY REQUIREMENTS
Symbols located in this service manual mean:
WARNING!
Warning o potential, hazardous situations. Especially important. One
must acquaint with this be ore connecting the converter. The non-ob-
servance o notices marked by these symbols can occasion severe
injuries o the personnel and the damage o the instrument.
CAUTION!
Designates a general use ul note. I you observe it, handling o the
converter is made easier. One must take note o this, when the instru-
ment is working inconsistently to the expectations.
Possible onsequen es if disregarded !
In the security scope the converter meets the requirements o the EEC Low-Voltage
Directive (EN 61010 -1 issued by CENELEC).
Remarks on erning the operator safety:
1. General
lThe PD8 converter is destined to be mounted on a panel.
lNon-authorized removal o the required housing, inappropriate use, incorrect
installation or operation creates the risk o injury to personnel or damage to
equipment. For more detailed in ormation please study the Users Manual.
lAll operations concerning transport, installation, and commissioning as well
as maintenance must be carried out by quali ied, skilled personnel and
national regulations or the prevention o accidents must be observed.
lAccording to this basic sa ety in ormation, quali ied, skilled personnel are
persons who are amiliar with the installation, assembly, commissioning, and
operation o the product and who have quali ications necessary or their
occupation.
2. Transport, storage
lPlease observe the notes on transport, storage and appropriate handling.
lObserve the climatic conditions given in Technical Data.
3. Installation
lThe meter must be installed according to the regulation and instructions
given in this Users Manual.
