BASIC INFORMATION
Description
GNOME232, GNOME485, GNOME422 and GNOMETTL are simple and inexpensive
converters of the 10/100 Ethernet to RS232, RS485 and RS422 respectively. They enable easy
connection of devices with serial interface to a computer network (e.g. a home or company
LAN, or the Internet), but are also able to extend a serial line to the other end of the world via
the Internet.
GNOME232 and GNOMETTL only differ in their hardware design and serial line levels.
GNOMETTL only features data lines at TTL levels and is supplied without any box.
The converters feature a “virtual serial port”, i.e. software which creates a new serial port in the
Windows operating system directed to the GNOME module via the Ethernet interface. The
converter is easy to configure using the supplied software or a WEB browser.

GNOME
Types of communication
Converters GNOME use several ports for the communication: The Data port (for the usual data
transmission) is a user-specific port, by default set to 10001. The port for setup via Telnet is
9999. The port for setup via WEB interface is by default set to 80 (it is also user specific).
TCP server/client
Upon switching on, the device expects data from the serial line and it is also ready to receive the
connection request from the Ethernet interface.
If the data come from the serial line, the TCP client mode is activated (see below). If a connection
request comes, the module is switched over to the TCP sever mode (see below).
The module may remain in the activated mode, or – after a specific idle time– it may interrupt the
connection and wait again for data from the serial line or the Ethernet interface.
TCP server
Upon switching on, the device listens on the selected port and waits for the client connection.
As soon as a client is connected, the data from the Ethernet are immediately sent to the serial line
and vice versa. If the client is not connected and the data from the serial line are coming, they are
stored in a cache and sent immediately upon the client connecting to the server.
If the client is idle or terminates the connection incorrectly, the module terminates its connection
after a preset idle time.
TCP client
When idle, the device waits for the data from the serial line. As soon as the data are received, the
device tries to connect to the server at a specified IP address. If the connection cannot be
established, the data are stored in a cache memory. Upon establishing the connection, the data are
sent out and, simultaneously, the data from the Ethernet are transmitted to the serial line.
UDP
The Ethernet data are expected on a preset port. When the data come from the serial line, they are
sent to the preset IP address. Within a UDP transmission, the response of the other side is not
checked; the application itself should be protected from data loss.

Virtual serial port
Virtual serial port is software by Lantronix Company that creates a new serial port in the
Windows operating system and this port is directed to the serial port of GNOME via the Ethernet
interface. Thus, your existing application does not have to be modified in any way and can
communicate with your current hardware over the Ethernet.
Fig. 13 – Typical connection for directing the serial line of GNOME to “local” COM on PC
Virtual serial port can be downloaded from je
www.papouch.com and is also available on the
supplied CD.
The window of the Virtual Serial Port can be found in
Fig. 15. The left part shows a list of COM ports that
are currently available in the system. The right part
shows the configuration of the selected port
(“Settings” tab) or a test of the port (“Com n Tests”
tab). The lower part shows a list of Ethernet devices n
the local network using Ethernet chips and modules
from Lantronix (the list can be updated by clicking the
magnifying glass icon in the upper bar).
A new serial port redirected to the serial port of
GNOME in your system can be created by following
the instructions below:
1) Click the icon showing a connector with cable
in the upper bar.
Fig. 14 – Virtual port manager (the port is
treated as a standard system COM)
2) In the dialogue window which opens choose
the desired number of the new COM port.
3) The port appears in the list on the left. The right part shows its parameters.

4) In the lower part of the Settings window enter the IP address and the number of the data
port of your converter and enter any other parameters if necessary. 5
5) After setting all parameters, click the icon with a floppy disk in the upper tool bar.
6) Now it is possible to test the connection using the “Com n Tests” tab.
7) The virtual COM port is now ready to be used. In your application you can now select the
number of the COM port you have entered before. Any data communication going
through the new “serial” port will run over the Ethernet via GNOME.
Fig. 15 – The main window of the Virtual Serial Port

More IP addresses can be set for one COM. After opening the COM port, the device will try to connect to
individual IP addresses and ports, one by one. If one attempt fails, it will try to connect to other addresses until
a connection is successfully established.

Idle Time
This setting determines the time interval of idle line (period of time during which no data are received
from RSxxx) after which the received data are packed and sent to the Ethernet. The following options
are available: 12 ms, 52 ms, 250 ms, 5 s.
Default value: 12 ms
Match 2 Byte Sequence
This activates the mode where the converter expects characters (Match Bytes) which serve as a
signal for preparing a packet to be sent. As soon as this character(s) is received, the packet is
prepared and send when another (any) character arrives. (This option is useful, for example, to
recognize characters preceding the checksum. The last character of the packet is a character which
is always the same and precedes the checksum. As soon as this character is received, the
converter waits for another byte to be added as the last one to the packet which is then sent.)
Characters in hexadecimal representation are entered in the Match Bytes fields.
Available options: None, One, Two
Flush Mode
This option defines the mode of working with buffer memory. Input Buffer is serial-to-Ethernet
buffer memory. Output Buffer is Ethernet-to-serial buffer memory.
Active Connection = connection that is initiated from the converter to the Ethernet.
Passive Connection = connection that is initiated from the Ethernet of the converter.
With Active Connect
Enable: Buffer is cleared with a connection initiated from the converter.

Active Connection – Client mode
This option activates the Client mode – The converter actively connects to the preconfigured
remote server (the server set below in Endpoint Configuration).
None: The Client mode is not active.
With Any Character: To establish a connection after the receipt of any character from the serial
line.
With Active Mdm Ctrl In: To establish a connection in the Modem mode.8
With Start Character: To establish a connection after the arrival of a particular character to the
serial line. Enter the character into the Start Character field.
Manual Connection: The converter will try to establish the connection if it receives from the
serial line a command in the following format: C[IP address]/[port]
Example of a command received from the serial line to establish connection with IP
192.168.1.105, port 4567: C192.168.1.105/4567
If the subnet mask restricts the range of the network's IP addresses, for example to 8 bits (the
"C type" mask – i.e. 255.255.255.0), the command can have an abridged format as follows:
C105/4567
Autostart: The converter will try to establish a connection to the remote address set in the
Endpoint Configuration section immediately after it has been switched on.
Endpoint Configuration

FAQ
Remove the password for Telnet or WEB
(The following procedure cannot be used for GNOME485.)
The password set for Telnet or WEB can only be removed via the serial line. The password
cannot be removed remotely via the Ethernet. Use the following procedure:
1) Connect your converter to a PC (GNOME232 via crossover RS232 cable; for other
converters it is necessary to connect to the RS232 serial port on the PC via the relevant
converter).
2) Disconnect GNOME from the power supply.
3) Run a terminal program on your PC10 and open the serial port to which your converter is
connected. Data connection parameters:
Speed: 9600 Bd
No of data bits: 8
Parity: none
No of stop-bits: 1
Data flow control: none
4) Press and hold the “x” key and connect the power supply to your converter. After a white,
the terminal displays the introductory text. Immediately confirm it by clicking Enter (within
2 seconds; otherwise you will not be allowed to enter the configuration mode).
5) The system will open the same menu as for configuration via Telnet.
6) In this menu choose the “Server” segment. In this segment you can find the “Change
telnet config password” option. Here, enter Y to indicate that you want to change the
parameter.
7) A window will appear prompting you to enter a new password. Here, enter a new
password or leave the parameter empty to disable the password.
8) In the menu then select “Save and exit” to save the new password settings.
