Introduction HG 76342-A
English, Revision 01, Date: 27.01.2014 3
1 Introduction
The radio modem HG 76342-A is intended to connect devices with Ethernet or serial
interfaces to a Wireless Local Area Network (WLAN) corresponding to the 802.11 a/b/
g standard.
The radio modem can receive and transmit data via 2 Ethernet LAN ports and can
transfer this data via a WLAN Interface to a matching WLAN access point that is con-
nected to a stationary LAN. The radio modem can also receive and transmit data via
a serial port. This data can be exchanged via a TCP- or UDP-Socket with other devices
by using the LAN or WLAN interfaces of the radio modem.
The HG 76342-A needs many parameters to handle all the different interfaces. The ra-
dio modem supports a Web interface to configure all these parameters. In addition a
further interface is available to locate, configure, upgrade and to monitor the radio mo-
dem. This interface is used by the UCP-Config-Program.

1.3 Interfaces
The interfaces are:
1. Mini-PCI-Socket
2. Two Ethernet-Interfaces 10/100 MBit + auto MDI (auto crossover function)
3. 1 serial interface with 6 status lines
4. 1 x USB connection (data logging)
5. Relay switch an optional an AUX input with optocoupler
The Ethernet ports have RJ45 plugs. Because of the auto MDI functionality the radio
modem can be attached to a HUB or the LAN port of a computer with standard patch
cables. The HG 76342-A recognizes the cable polarity and automatically connects the
right signal lines.
The serial port is connected via a 9 pin female D-SUB connector. The pin allocation
makes it possible to connect to a computer COM port with a 1 to 1 serial cable. The
exact pin allocation is shown in Table 1 on page 6 below. The radio modem can be
powered by a supply with a voltage between 10 — 72V. The typical power consumption
is 4.0 Watt.

1.5 Meaning of the LEDs
The 5 LED's at the front side show the operating status
of the HG 76342-A. All lamps are 2 color red and green
shining LED's. If both LED's are on, the lamp is shining
orange. Reset is no LED but instead a push-button used
to reset the device (see section 2.3 on page 10).
LED Function
On - off: on power supply
- green: power supply OK
- orange green blinking: Normal operation, HG 76342-A ready for service
Serial - steady off: no communication partner is connected to the radio modem
- green: A communication partner is connected to the radio modem. When
data is transmitted or received via the serial port the LED is switched off
shortly.
Port 1
Port 2
- off: no device connected to the LAN port.
- green: an Ethernet device is connected to the LAN port. Blinking shortly sig-
nals activity.
WLAN - Red blinking: searching for RF-connection (scanning) or doing the authenti-
cation.
- steady green: Found a suitable Access-Point and established a connection
- green + orange blinking: RF activity (receive or transmit)

2FirstTimeSetup
To set up the HG 76342-A it has to be connected with a patch cable to the Ethernet
interface of a computer. After applying power, the green “Link LED“ on the RJ45 con-
nector shines when a link is detected. The yellow “100 MBit” LED indicates a 100 MBit
connection.
The “Port 1 or 2” LED on the front panel shines green when a connection has been
established via the Ethernet. The “WLAN” LED on the front panel will be blinking red
because usually no suitable WLAN is recognized.
2.1 Montage
Das Gehäuse steht in zwei Varianten zur Verfügung, einmal in einem Hutschienenge-
häuse und einmal in einem Flanschgehäuse. Im Folgenden finden Sie Gehäusezeich-
nungen mit den Abmessungen der Montagevorrichtungen.

2.2 The UCP-Config Program
To do the „first time setup“ the radio modem has to be connected via the LAN-Interface
to the computer (PC) that runs the UCP-Config-Program.

First Time Setup HG 76342-A
English, Revision 01, Date: 27.01.2014 10
NOTE! You have to observe:
-The connected PC should have a fixed IP address. (no DHCP)
-The LAN-Interface at the PC must be detected as connected. Check the parame-
ter of the LAN-Interface with the „ipconfig“-command.
-If the LAN-Interface of the PC is correctly recognized then press the „refresh“-but-
ton of the UCP-config-program.
-An active firewall could prevent the communication to the radio modem.
After the start the UCP-Config-Program ascertained all network interfaces that are ac-
tive at the PC. After this the UCP-Config-Program sends broadcast UDP requests to all
these interfaces. The registered answers of the HG 76342-A devices are shown in a
list.
Figure 8 Screenshot UCP-Config program
All located HG 76342-A devices are shown in a list with their station names, firmware
versions and addresses. The WLAN connection is also shown with a signal quality val-
ue. The value can be interpreted as follows:
-Signal 40 very good connection
-Signal 30 good connection
-Signal 20 connection is OK, the device starts to search for better AP’s
-Signal < 20 connection restricted, the bit rates will be lowered
NOTE! For a more detailed description of the UCP config program
please refer to the separately available manual.
2.3 Reset to factory default
The factory default settings can be restored by pressing the reset button located on
the front panel for a period of more than 10 Seconds. While the reset button is pressed,
the “ON”-LED blinks orange more faster. When the radio modem does a restart the de-
fault settings are configured. Now the reset button can be released.
