EZL-200F - Conventer Ethernet - RS-232/422/485
EZL-200F is encased conventer RS232/422/485 for data transmition via
Ethernet network with a Real-Time Operating System and with data transmition security SSL.
For Ethernet connection UTP cable with RJ-45 connector is used.
Module can be without further programming connected directly to
RS-232/422/485 interface of any device.
Conventer
EZL-200F
converts serial line RS-232C,
RS-422 or RS-485 to Ethernet - standard 10/100Base-T. Serial interface
is changeable in the Conventer setup and ended with 9 pin Dsub male connector.
Network part is ended with RJ-45 connector cables.
The result is Ethernet conventer which differs from classic
RS-232 / Ethernet conventer in the fact that serial interface can be switched between
RS-232 RS-422 or RS-485 by software program.
An advantage is easy setup by the utility for Windows OS, AT commands or
by remote telnet terminal.
Wide spectrum of communication modes is supported according to user needs.
For secure TCP communication and data transmition is possible to use
authentication and encryption SSL 3.0 / TLS 1.0. It can be used in TCP server
or TCP client mode. |

Applications
Conventer
EZL-200F is connected to the device communicating via serial RS-232, RS-422 or RS-485 transmition.
Last two possibilities allow serial network industrial communication.
Opposite side is represented by other Ethernet device (e.g. PC), HUB, switch or router,
which accesses serial port into classic Ethernet network.
So it can communicate with any PC connected to the network or to the Internet.
On the opposite side can be of course another EZL200F or other conventer (e.g. PortStore or PortBox).
- Remote sensors' communication (e.g. electronical thermometers) and PC via LAN.
- Remote monitoring systems
- ATM systems
- Traffic a informations systems (displays)
- health check systems
- Remote data retrieving of the MaR system (Measuring and Regulation).
- Ethernet realization of factory networks with connection to LAN and Internet
- Security systems
- Remote control of industrial machines
- Wireless communication of measuring devices (multimeters, oscilloscopes and others)
- Data synchronization of portable devices with PC

Ethernet communication modes
:
Converter can behave as a client/server device according to chosen MUX TYPE (function modes):
|
Communicationmode |
Protocol |
ConnectionType |
|
|
T2S |
TCP
|
Passive
=
TCP Server
|
Converter listens on the selected port and awaits client's connection which can thereafter send or receive data |
|
ATC |
TCP |
TCP Client
or
TCP Server |
Communication is operated by transmitting AT commands over serial line which allows setting of the client/server mode (COD, T2S). |
|
COD |
TCP |
Active
=
TCP Client |
Converter establishes connection when RS-232 port receives the data and allows a transmition. |
|
U2S |
UDP |
Point-to-Point Broadcast |
Defined TCP port awaits data and sends them to IP address without a transmition control. This allows using a broadcast. |
Other supported communication protocols :
ARP, ezCFG, DHCP, TELNET,
PPPoE, Multimonitoring
TCP communication security:
SSL3.0/TLS1.0 (RSA, RC4/DES/AES)
Experiences
ezVSP (Virtual Serial Port):
-
You'll find the program on the provided CD,if necessary
download
the version from september 2005.
- Allows changeing speed of RS232 interface remotely.
- Installation of this program is conditioned by ownership of at least one module.
-
During installation it's necessary to enter the MAC address of the module and a key which is obtained by a
registration
on Sollae webpage. Further installation description can be found in the
manual.
Configuration over ezSerialConfig:
- To create contact between configuration program and the conventer must be connected to LAN and the firewall of the PC must be configured properly.
- Wrong configured Firewall can disallow communication with conventer.
- After program is started it's appropriate wait 10 seconds before establishing connection with EZL200F.
-
For reasons of universal use of ezConfig for all products of Sollae, it is possible to select and change only parameters belonging to corresponding module. Other parameters are locked up.
General:
- The connection of the module's serial port and the application must be performed by so called "zero mode" principle. That means interconnection of the RxD - TxD and RTS - CTS pins from the view of both ends of the connecting cable.
- If new firmware is loaded, it's good to exactly follow the application manual of the conventer.
- Conventer EZL-200F contains function to automatically detect 1:1 cable or cross-over cable.

FAQ & support
Question
:
Where is the difference between EZL200F and other ordinary conventers.
Answer:
From the user's view is EZL200F conventer not only of usual RS232 line, but
it also converts it's industrial versions RS422 and RS485. Moreover EZL200F
contains Real-Time operation system, which together with Telnet allows set and
change parameters of conventer via any terminal, and so independetly on OS of the PC.
It's useful for example for OS Linux or Unix. After all it contains secure transmition by
SSL3.0/TLS1.0 protocol, which disallows unauthorized reading of communication over LAN.
Question
:
Is it necessary to program the module some way if
I only need a simple GateWay from RS-232 (TTL) to TCP/IP or UDP/IP?
?
Answer
:
NO, you only need to use the module and set necessary parameters.
You don't have to program anything!
Question
:
Would the module work as a Virtual Serial Port
under Windows?
Odpověď
:
YES, the converter fully supports the function of remote Virtual Serial Port through TCP/IP.
Moreover the producer offers free program ezVSP to download.
It's only necessary to register and give the MAC address of the module you've bought.
Question
:
Is it possible to configure the module also by other means than through
Windows programs?
Answer
:
YES, by the means of AT commands through serial port and any terminal. The sequence of ASCII chars as AT commands can be thus transmitted even from singlechip microcontroller.
The list of usable AT commands with examples of correct
configuration sequences contains the detailed manual for specific module.
Question
:
Is it possible to change a FirmWare in the module ?
Answer
:
Yes it is, innovated FirmWares can be downloaded from the Sollae's webpage
(www.ezTCP.com) and load into the module via RS-232
and wflash program or via Ethernet by the means of the program hotflash.
Question
:
Does the ezVSP (Virtual Serial Port) software allow creating more than one virtual port?
Answer
:
Yes, this software allows to set up to 127 virtual ports on one PC.
Detailed guide on this can be found in the program's manual which
is free to download on these pages in menu item "Datasheets".
Question
:
What does SSL protocol serve for?
Odpověď
:
Secure Sockets
Layer (SSL) is protocol for authorization and encryption of data transmition
via
Ethernet network between two subjects (client-server).
It prevents reading of data captured during the transmition by
unauthorized third party. For encryption the RSA method is used, it
uses freely distributed public key and private key of particular
device, which allows decryption of incoming message. SSL runs over
TCP/IP protocol in the server or client communication mode.
