Introduction – Chapter 2
The Client Adapter HG G-76343/4/5 is a wireless LAN adapter (in Götting docu-
ments the terms radio modem respectively WLAN client are used synonymously)
that connects devices via Ethernet, USB or serial port to wireless networks conform-
ing to the 802.11 a/b/g/n standard. The HG G-76343/4/5 connects all devices that
are connected to its LAN interface to a network reachable via WLAN.
Via a serial interface the HG G-76343/4/5 can receive and transmit data that is sent
or received by a communication partner connected to the network (WLAN or LAN).
This communication partner can also be a HG G-76343/4/5 or a computer that
sends resp. receives via a matching application. The USB port makes it possible to
connect extensions like e.g. additional serial interfaces or I/O interfaces.

ing possibilities:
All variants operate with the same firmware and can be configured with the same
program. You can download them from the following address:
2.2 Interfaces
The following interfaces are available (depending on the variant):
1. 1 - 4 x Ethernet interfaces 10/100/1000 MBit/s + Auto-MDIX (auto crossover
function), port 1 has PoE (Power over Ethernet).
2. 1 x serial interface with 6 control wires.
3. 1 x USB 2.0 interface e.g. for label printers or for the logging of system status
messages on USB memory sticks.
4. 1 x relay switching contact.
5. Only on request: Input with optocoupler.
The Ethernet connection is connected via an RJ45 connector. LAN port 1 has a PoE
function (IEEE 802.3af) so that the HG G-76343/4/5 can be powered by this port.
The serial port is connected by a 9 pin D-SUB plug. The assignment is selected in a
way that a 1:1 serial cable can be used for the connection to a serial COM-Port of a
PC. The exact assignment can be seen in Table 3 on page 13.

3.2 Initial Startup via LAN
For the initial startup please connect the HG G-76343/4/5 via the Ethernet-Port with
a PC using a patch cable. When turning on power supply voltage, all LEDs briefly
blink white.
After that only the ON-LED lights up green, which soon starts blinking orange (red &
green) and green. This indicates the boot process. After about 15 seconds the appli-
cation is ready and the LEDs indicate the modes described in section 2.5 on page 13.

Commissioning – Chapter 3
3.3 The MC-Config Program
For its initial startup the radio modem is only able to communicate via its LAN-Port
because typically there is no wireless network with a suitable SSID. The
HG G-76343/4/5 is then connected to a PC via the Ethernet port.
3.4 Commissioning via the Web Interface
If you do not want to or cannot use the MC-Config program, the HG G-76343/4/5
can also be commissioned using a WEB browser. For this purpose, the LAN interface
of the commissioning computer must be set to a fixed IP address. Suitable would be
e.g. the IP 192.168.170.1 with the subnet mask 255.255.255.0.
If the HG G-76343/4/5 starts with the default setting (see below), a connection to
the radio modem can be established with the WEB browser by specifying the ad-
dress 192.168.170.100 and the home web page of the radio modem can be dis-
played (see section 5.1 on page 38). From there the necessary settings can be made.
3.5 Reset to Factory Settings
By pressing the Reset button for a long time, the HG G-76343/4/5 can be set back
to its factory settings. When keeping the reset button pressed, the radio modem
goes through different sequences that are visualized by all four LEDs lighting up in
the same color.
The LED-sequences start with lighting up in white, then blue  red  green; re-
starting with white. Holding the Reset button pressed after the third time the all LEDs
light up blue, the device is set back to its factory settings. All LEDs are off during the
reset to factory settings. After that, the Reset button can be released. When the Re-
set button is released before the factory reset was initiated, then the HG G-76343/
4/5 needs to be restarted by briefly pressing the Reset button again.
The HG G-76343/4/5 has the following (important) factory settings (device name ac-
cording to variant):
Device Name: "HG76343"
SSID = "DefaultWLAN"
Encryption mode = no encryption
MODE= 802.11b/g/n
IP = 192.168.170.100
Netmask = "255.255.255.0"
Gateway = 192.168.170.1
user = "" (leer)
password = "" (leer)
SER1: inaktiv
Relais: inaktiv
Input: inaktiv
The MC-Config application is described in chapter 4 on page 18 (including the fur-
ther commissioning steps).

18 Chapter 4 – MC-Config Program
4.1 Functional Description
The MC-Config Program can perform the following functions in a system with one
or several radio modems HG G-76343/4/5:
Locating the WLAN clients in the network (via LAN or WLAN)
Configuring the WLAN client parameter including saving and loading of config-
urations via files
Transfer of firmware files to WLAN clients
Restart WLAN clients (reboot)
Reset of WLAN client parameters to default settings (Factory Default)
Display of current connection parameters of the WLAN clients in the network
Retrieve system messages and log files from the WLAN clients
4.2 IP Protocols and Ports Used
The MC-Config program uses the UDP port 17784 to request status messages
from the WLAN clients Firmware upgrades are also transmitted via UDP if the WLAN
client can only be reached via broadcast. If there is a unicast connection to a WLAN
client, firmware files are transferred via the TCP port 17784. Log files and (W)LAN
recordings are downloaded via TCP port 17785.
4.3 Encrypted Transmission
The MC-Config program encrypts the transfer of config files, the upload during firm-
ware upgrade and the download of debug logs if the WLAN clients support this. This
encryption is possible for radio modems with firmware 2.12k and higher.
MC-Config Program
The MCConfig program version 2.0.2.51 and higher expects that in the directory in
which the MCConfig_xxx.exe file is saved, also the DLLs libeay32.dll and
ssleay32.dll contained in the ZIP file are stored. If these are not present, an error is
reported after starting the program.

MC-Config Program – Chapter 4
4.4 Initial Startup
For the initial start-up WLAN clients can communicate only using the LAN connec-
tion, because usually there is no wireless network with a matching SSID.
Figure 11 MC-Config Program: Setup for the initial operation of a WLAN client
The HG G-76343/4/5 is connected to a computer that has an Ethernet port. The MC-
Config program is started on the computer.
Figure 12 Initial commissioning with the MC-Config Program
What to pay attention to:
The connected computer (notebook) should have a fixed IP-address (no DHCP)
on the LAN interface.
This IP address should appear in the status field at the bottom left of the MC-
Config program (see Figure 12 above). If this is not the case, you can check the
setting of the LAN interface of the PC by entering the ipconfig command in the
command line on the PC.
If several IP addresses are listed there, you can activate only the relevant inter-
face with Configure Interfaces (see Figure 12 above).
After changing this configuration, press the Refresh button on the MC-Config
program (see Figure 12 above).
An active firewall on the computer could prevent the communication with the
WLAN client.

4.5 Operation
After being started the MC-Config program first detects all network interfaces that
are currently active on the computer. Via these interfaces queries are then sent out
per Broadcast UDP/IP that will be answered by HG G-76343/4/5 devices. The re-
sponding devices are registered and displayed in a list.
Figure 13 MC-Config Program: User Interface
In addition to the device data such as name, serial number, firmware version, IP ad-
dress and MAC address, WLAN connection data is also displayed. Initially, you can
only see the set SSID. If there is a connection to an access point, the MAC address
and, for certain WLAN systems, the name of this AP are also displayed.
Below the list there is a field for messages from the MC-Config program. Here also
debug messages from WLAN clients are displayed, if this function has already been
activated on the WLAN client. By double-clicking this field all messages saved so far
are opened in a text editor.

No Name Function
1 Refresh The existing network interfaces are determined again. If you have changed the
settings of the network adapters on the PC or plugged in new LAN cables, you
should first update the currently available network interfaces with Refresh. In addi-
tion, the scan for existing WLAN clients is restarted.
The scan ranges are set under Configure -> IP-Ranges, s. 4.6.3 on page 27.
2 Config This opens the configuration dialogue for the selected radio modem. For this pur-
pose, the configuration file is first retrieved from the WLAN client. When the con-
figuration has been received completely, a window opens in which the
configurable parameters of the WLAN client are displayed.
Editing the configuration is described in section 4.7 on page 32.
3 Upgrade Allows to transfer a firmware file to a WLAN client, see section 4.9 on page 34.
