1. APPLICATION
At present, more and more PC computers operating in industrial computer-based
systems are equipped only with a USB (Universal Serial Bus) serial interface. This
interface serves to communicate with other computers and devices in the framework of the USB network.
The PD12 converter is a device enabling, in a very easy way, to create the
connection between the USB and the RS-232 port , ensuring simultaneously between them the galvanic separation. The USB interface is destined to communicate with
the computer, however the RS-232 interface is destined to communicate with
devices in the object side.
The maximal baud rate is 921.6 kb/s.
The converter does not interfere in the structure of transmitted data and is compatible with a lot of industrial communication protocols, i.e. MODBUS RTU, MODBUS
ASCII, LUMBUS, and the like.
A programmed controller of the network serial port for the master system computer
is added to the set. It allows supervising programs to exchange data with industrial
objects via the PD12 converter.
2. CONVERTER SET
The PD12 converter set includes:
- PD12 converter

3.3. Installation of the COM port for Windows
The PD12 converter unfair advantage of FTDIBUS and FTDIPORT driver controllers,
licensed by Future Technology Devices International Ltd.
This software creates a new device of the Universal Serial Bus system - USB RS232 converter of PD12 type and connected Port (Com) to it - PD12 USB-RS232
Port(COM).
The installation of a controller in the Windows system causes the addition of the
next 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 converter to the USB port, the operating system will inform us
about the occurrence of a new device by means of the system. The creator, finding
the new hardware of the Universal Serial Bus will be started automatically.
One must proceed acc. to the creator suggestions, choosing the „Installation from
the indicated location” and giving the access path to controllers being on the plate
added to the converter.
On the plate with controllers, there are controllers for following operating systems:
Windows 98, 98SE, 2000, ME and XP. When installing controllers, information that
the software has not been submitted to tests in accordance with the Windows
system
%
can occur. One must ignore such information and continue the further installation.
After closing the creator, the system detects immediately the next device - USB
Serial Port.
The creator to find a new hardware will be started again.
After the successful installation termination, the system will inform about the installation of a new hardware.
Two new devices will appear in the device Manager - The USB-RS232 converter of
PD12 type and PD12 USB-RS232 Port (COM).
3.5. Example of Lumel Heat and Lumel 3000
configuration to co-operate wit PD12
Lumel-Heat and Lumel 3000 systems communicate with industrial devices by means
of COM serial ports.
After installing additional COM serial ports, one can refer to them in systems of
LUMEL series. Then, one must introduce in new and existing applications or system
configurations, or change supervision cancellations to added communication ports.
Lumel-Energy programs in older version than 2.5, service maximally 4 serial ports
and in such systems, serial ports must be installed as COM1...4).
4. NOTES
The PD12 converter can work with a maximal baud rate up to 921.6 kb/s on lines to
15 m length.
!
&
In the environment with unknown interference level it is recommended
to observe following principles:
l Connections of communication interface circuits must be conduct
individually by twisted wires in a shield.
l Apply 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.
