G 76341-A
Introduction
G 76341-A is a WLAN adapter for connecting devices with ethernet- or serial interfaces to wireless networks according to 802.11 a/b/g standard. It connects all devices of
the LAN segment to which it is linked via the Ethernet interface with a WLAN network.
Via its serial interface it is able to receive and transmit data that is transmitted/received
by a communication partner linked via the networks (WLAN or LAN). This communication partner in turn may be an G 76341-A or a PC/controller, receiving or transmitting
this data via a compatible application.
The following picture illustrates the operational subsystems.
Figure 1
Block diagram
The main component of G 76341-A is a 32 bit network processor, controlling all functions. The interfaces are:
1.
Mini PCI socket
2.
Ethernet interface with 10/100 Mbit + Auto MDI (auto crossover function)
3.
1 or 2 serial interfaces with 6 control lines per interface (2nd serial interface
optional)
4.
Relay switching contact and switching input with optocoupler (not available with
2nd serial interface)

Introduction
G 76341-A
The Ethernet connection is designed as a RJ45 plug. The auto- MDI- function enables
connecting the G 76341-A to a HUB (switch) as well as directly to the LAN- connection
of a PC/controller without changing the patchcable. The G 76341-A Ethernet interface
identifies the polarity of the lines automatically and switches the signal lines internally
correctly.
The serial interfaces will be connected via a 9-pin SUB- D socket. The pin allocation
is chosen in such a way that this interface can be linked to the COM-port of a PC
through a one-to-one serial cable. For the detailed allocation please refer to Figure 1
on page 5.
For power supply HG 76341 requires a voltage source in the range of 8-30V (12 V typ.).
The current consumption at 12 V is approximately 300 mA. The following sketches
show the LED display and connections on the G 76341-A front panel.

Commissioning
For the initial start- up please connect a PC/controller with an ethernet interface to the
ethernet interface of G 76341-A using a patch cable. As the LAN interface of the
G 76341-A is able to determine the polarity of the cable and automatically connect it
correctly, it does not matter whether a “parallel / straight” or a “crossover” patch cable
is used.
Once the power supply has been switched on, the green LED at the G 76341-A LAN
interface illuminates if a LINK- impulse is identified. The yellow LED lights up whenever
a connection is run with 100 Mbits.
The LAN LED on the G 76341-A front panel lights up green whenever a connection at
the Ethernet port has been identified. The WLAN LED on the front panel blinks orange
as long as no suitable radio network has been identified.

4.6 Advanced Page
The “Advanced page” offers the setting of further parameters for the G 76341-A operation within the WLAN.
4.6.1
Cloning
The parameter defined as cloning determines which kind of MAC address the radio
card of G 76341-A uses. Normally the MAC address will be allocated by the producer
of the radio card and remains unchanged. All devices connected to WLAN via the ethernet interface communicate with this MAC address.
The original MAC address of the user at the Ethernet connector related to the IP address of the user is specified in a table included in the G 76341-A. If a data packet
reaches G 76341-A via Ethernet, G 76341-A verifies whether an input with this source
MAC address already exists. If not, a corresponding entry will be executed. Afterwards
it will be checked if there exists an entry for the Destination-MAC-Address. If so, this
indicates that the receiver of this data packet is located on the wire bound side and
data does not have to be transmitted via WLAN. If not, the source MAC address will
be overwritten with the MAC address of the radio card and the data packet can then
be transmitted via WLAN.
Whenever the G 76341-A receives a data packet via WLAN, the Destination-IP-Address will be determined. In addition to the destination IP address the original MAC
address will be determined using the internal table. This MAC address will be inserted
into the data packet and then transmitted via the Ethernet interface.
This procedure is only possible in networks transmitting data via the IP protocol.
Should other protocols be applied, G 76341-A can be induced to transmit the MAC
address of the first received data packet via Ethernet interface to the radio card. This
procedure is called Cloning. Thus it is guaranteed that all data packets of the WLAN
side, destined for the connected device, will reach the G 76341-A. G 76341-A is able
to transfer all data packets received via the Ethernet interface without any further processing. This method implicates that only one device can be connected to the Ethernet interface of the G 76341-A.
4.6.2
Roaming
Roaming means the automatic switching of the Access Points carried out by G 76341A if the reception area of an AP is left and another AP, providing a better signal quality
is available. For this purpose G 76341-A lists all APs from which signals (beacons) are
received.
In order to receive beacons from other APs G 76341-A over a short period of time, the
user has to switch to the corresponding channel and listen to any incoming signals.
This might interfere the normal data traffic G 76341-A has to process. Therefore this
procedure will be executed in a different intensity — depending on the reception quality
of the AP currently being active. For maximum effectiveness during this process, the
user may enter the channels to be searched for Aps on the ‘Advanced page’ of the
G 76341-A.

4.7 Serial Interface Settings
G 76341-A provides up to 2 serial interfaces. The setting of the parameters is carried
out via two separate WEB sites.
4.7.1
Section “Network-Configuration“
Different user modes are available for the serial interfaces:
English, Revision 02, Date: 23.03.2009
17
Setting of the Parameters via WEB Interface
1.
TCP/IP server mode:
Using this setting G 76341-A opens a socket in the “List Mode”, i.e. a certain
local port expects a connection set-up. G 76341-A keeps only one connection
at a time. In this mode only the port number is indicated as a parameter.
2.
TCP/IP client mode:
Here G 76341-A actively opens a TCP connection on the indicated port of
another network node. This node may be another G 76341-A or the controller,
waiting for a connection on the named port. Besides the port number the IP
address of the communication partner has to be specified as well.
3.
UDP/IP mode:
In UDP mode G 76341-A waits for data over the “Local Port”, being transmitted
via UDP/IP. The serial data received will be transmitted by UDP/IP to the “remote
port” of the remote IP address. The UDP mode shall be used in those particular
cases where a disconnection of the communication partners occurs frequently.
Please note that the UDP protocol does not guarantee a correct data transfer.
4.
Printserver mode:
In the printserver mode
G 76341-A starts a TCP/IP
socket in the server- mode,
waiting for link establishment
on Port 515. In this mode the
program of G 76341-A is able
to accept print jobs according to the method described
in RFC1179. If you want to
integrate a printer under Windows applying this method,
the connection in Windows
has to be configurated as follows:

Windows-features for a printer connected via LPR
COMSERVER-Mode:
Using Windows G 76341-A is able to provide virtual COM-ports in this mode.
Therefore a software product of Wiesemann & Theis (www.wut.de) will be
installed on the Windows- PC. The software tool is designated / is operated as
COM redirection. The W&T COM redirection, in connection with G 76341-A, is
able to address serial data terminals.
Simply install the COM redirection driver for Windows and enter the IP address
as well as the Port of G 76341-A. Periphal equipment of all kind, provided with a
serial interface, can be addressed via WLAN or ethernet network quite simply.

Setting of the Parameters via WEB Interface
4.7.2
G 76341-A
Explanations concerning the “keep alive”- settings
Once a TP/IP connection has been established, it remains until one of the communication partners terminates the link. Should the connection between G 76341-A and the
network communication partner be disconnected without having closed the TCP/IP
connection before, it might happen that G 76341-A does not reconnect.
TCP/IP socket can be induced to transmit a data package without any data content in
certain intervals (keep alive periods) to its counterpart. Supported by the communication partner, a corresponding answer will be returned. If this answer is entered, the
connection will be considered as existent / established. If the answer fails for a certain
number of attempts / trials (keep alive probes), the connection will be closed and
G 76341-A restarts the TCP/IP socket.
4.7.3
Comments on “Send- Trigger Configuration”
Initially characters received by G 76341-A will be buffered. Certain criteria have to be
met / fulfilled when the buffer’s content will be transmitted via network.
1.
Byte Trigger: The user specifies a number of bytes. If this number is achieved,
the buffer will be transmitted via network.
2.
Timeout: A timer with the indicated value will be started if a character has been
received. Each further character received restarts the timer. If the timer runs out,
data received up to now will be transmitted via network.
3.
Delimiter: The user sets a certain character. If this character will be received, all
bytes buffered up to now as well as the delimiter will be send.
4.7.4
Comments on “Handshake Mode”
This paragraph determines, how the ready-to-transmit / ready- to-receive state of the
communication partner is signalized. Applying signals RTS, DTR G 76341-A is ready
to receive. Using input signals CTS, DSR the serial device being connected signals
that it is ready to receive. Signals DCD and RI applied to G 76341-A can be transferred
to the network communication partner of G 76341-A.
G 76341-A is able to control data flow by remote control or independently (local). The
following modes are available for the user:
1.
no Handshake: Signals CTS/DSR will not be evaluated. Only RTS and DTR will
be set active, if the serial interface is connected via network.
2.
XON / XOFF: G 76341-A transmits and receives the flow control characters
XON= 0x11 and XOFF = 0x13. G 76341-A sends a XOFF character to the serial
partner if the buffer in G 76341-A is nearly filled. If the buffer is almost empty,
G 76341-A transmits an XON character.
3.
RTS/CTS: Applying signal line RTS G 76341-A is ready to receive. It analyzes
signal DSR to identify the ready-to-receive state of the serial partner

G 76341-A
Remote: In this mode G 76341-A transfers the status of signal lines CTS, DSR,
RI and DCD to the network communication partner, using a separate socket
(Port). Thus the user has to indicate further details for this setting.
The states of the signal lines are designated as character strings. Certain letters
describe the state of a certain signal line. If the letter is written with a capital it
means that the signal is active. Small letters indicate an inactive signal.
The allocation is as follows:
'D' = DSR active
’d' = DSR inactive
'R' = CTS active
’r' = CTS inactive
'C' = DCD active
’c' = DCD inactive
'I' = DSR active
’i' = DSR inactive
The data received will be interpreted in G 76341-A as follows:
'D' -> set DTR active
’d' = set DTR inactive
'R' -> set RTS active
’r' = set RTS inactive
C and/or c and I and/or I are not translated in G 76341-A.
6.
3964R: This is a special protocol, particularly applied to communication with
PLC components. In this case the ready-to-transmit / ready-to-receive state is
signalized by using special characters and sequences. You will find the specification of this protocol in the relevant literature.

Optional Adjustments
5.1 Configuration of the Onboard- Relay
G 76341-A is optionally equipped with a switching relay. Thus a switching relay, which
can be guided via network or a switching input, is available to customers. Each relay
contact can be configured to be a break or normally open contact.
Type of Relay Control:
- not active = not used
- UDP = UDP / IP socket on “Local Port”
- TCP = TCP / IP Server Socket on “Local Port”
- internal = Control via input signal
If the switching position of the relay shall be
restored after a reboot (reboot by software)
check the appropriate box.
If the Relay shall be switched on after power
up check the corresponding box.
Portnumber for the Mode option UDP + TCP.
Character string for connecting the relay. If no
indication is provided, any data switches the
output to ON.
Character string for switching off the relay.
Defined time in seconds until the relay output
returns automatically from the On state to Off
state.

5.2 Configuration of the Switching Input
An optional feature of G 76341-A is the switching input. This switching input is connected to the processor via an optocoupler. There are two ways to configure the
switching input: either it indicates the switching condition using the network or it operates the onboard relay.
Operating mode:
- not active = no function
- UDP = sending the status via an UDP socket
- Relay ON = switch on the relay when the input signal is active
- Relay OFF = switch off the relay when the input
signal is active
- toggle = toggle switching condition when operating
the input signal
IP address and port of the communication
partner where to send the signal conditions
per UDP / IP
Character string being transmitted if the signal is active.
Character string being transmitted if the signal is inactive.
The respective character strings will be send
if the input signal changes. Selecting “Sample Rate” defines the interval the current status will be transmitted even without any
signal change.
