1. APPLICATION
RS-485/Ethernet Wi-Fi converter PD8W type allows master
devices to transmit data via a wireless Ethernet Wi-Fi network to the
devices with RS-232 and RS-485 interface.
The converter has three operating modes: RealPort network
service, serial bridge service with the UDP protocol, TCP Socket service.
In the first and third mode, the switching master device of the system
is a PC using Ethernet Wi-Fi interface. In the second mode, the converter
works with a device with Master function and RS-232 and RS-485 serial
interfaces.
The converter PD8W to work with RealPort network service
requires the installation of a virtual serial port driver on a PC with Microsoft
Windows. Thanks to the PD8W type converters, this driver provides the
existing master systems, i.e. programs like Lumel Heat and Lumel En-
ergy, the ability to transmit data between devices with RS-485 or RS-232
interface using Ethernet Wi-Fi network (Fig. 1). When used in this way,
the converter allows to work with one master computer in the given time.
When using PD8W to support Modbus and Lumbus industrial protocols
- its correct interaction with master systems installed on a PC depends
on the built-in mechanisms to control time intervals between the received
transmission characters.
Using PD8W in the second mode, the RS-485 bus can be
expanded with successive segments using additional PD8W convert-
ers and Ethernet Wi-Fi local network. Properly configured, one pair of
converters allows to build a system working in the serial bridge mode
(Fig. 2). It is also possible to configure their operation in „one-to-several”
mode (as a set including up to 65 converters – Fig. 3). Function 2 of
the converter operates in the Ethernet Wi-Fi local network with UDP
datagram protocol support.

6
Function 3 operation is very similar to the converter working with
RealPort network service except that it is not required to install software
virtual serial port driver on a PC with Windows. Communication between
a PC and PD8W converter is via TCP Socket mechanism. In this case,
in order to connect to the device, it is necessary to specify an IP address
of the converter and a port number (Fig. 1).

3. BASIC REQUIREMENTS, OPERATIONAL SAFETY
Symbols located in this manual mean:
Especially important, please read before connecting the
converter. Non-compliance with the comments marked by
this symbol could result in damage to the converter.
Should pay attention, if the converter is not working as
expected.
Caution:
Removal of the converter housing during the warranty period voids
the warranty.
Comments concerning safety:
Assembly and installation of the electrical connections should
conducted only by people authorised to perform assembly
ofelectric devices.
Always check the state of connections before turning
the converter on.
Prior to taking the converter housing off, always turn the supply
off and disconnect measuring circuits.
The device is designed to installation and usage in the industrial
electromagnetic environment.
Aswitch or a circuit-breaker should be installed in the building
orfacility. It should be located near the device, easily accessible
bythe operator, and suitably marked.
2. CONVERTER SET
Complete set of the converter includes:
- PD8W converter 1pc,
- PD8W user’s manual 1pc,
