3 Quick start
This section details how to power-up, connect to and communicate with the AsteRx-U. The
AsteRx-U has an on-board web interface which the user can connect to in three ways:
Ethernet, USB or WiFi. The AsteRx-U is fully configurable using the web interface. Please
note that older versions of certain browsers may not display properly on the web interface.
3.1 Powering the AsteRx-U
Using the supplied open-ended power cable, the receiver can be powered by applying 6
to 36 V via the power-in wire. The receiver can also be powered using the power adapter
(optionally available). The power socket is indicated in Figure 3-1.
Figure 3-1: Rear panel power socket
There is a power button on the front panel as shown in Figure 3-2 which you may also have
to press. If the AsteRx-U loses power while the power button is on, then it will automatically
boot up when power is restored.
Figure 3-2: Front panel power button
When the unit is powered initially, the front-panel LEDs will will follow a boot sequence
pattern.

3.2. CONNECTING AN ANTENNA
3.2 Connecting an antenna
The rear panel of the AsteRx-U has two TNC connectors for GNSS antennas: one for the main
antenna and one for an auxiliary antenna for heading applications. The AsteRx-U MARINE
has an additional TNC connector for a dedicated L-Band antenna. To get started, connect an
antenna via an antenna cable to the main antenna connector of the AsteRx-U indicated in
Figure 3-3.
Figure 3-3: Rear-panel main antenna connector
3.3 Connecting to the AsteRx-U via the Web
Interface
You can connect to the receiver on any device that supports a web browser using the
receiver’s on board Web Interface. The connection can be made using either USB, Ethernet
or WiFi. The following sections describe each of the connection methods.
3.3.1 Using the USB cable
Connect the combined USB/Ethernet cable to the connector labelled ’ETH USB’on the rear
panel of the AsteRx-U and indicated in Figure 3-4.
Figure 3-4: Rear panel USB and Ethernet socket
The first time that the USB cable is connected to a device, you may be prompted to allow
installation of drivers which can take several minutes. When the drivers have been installed,
it is recommended to unplug then re-plug in the USB cable on your device to fully activate
the drivers.
When the drivers have been correctly installed, the USB connection will appear as a
removable storage device as shown in Figure 3-5.
17

3.3. CONNECTING TO THE ASTERX-U VIA THE WEB INTERFACE
Figure 3-5: Screenshot showing USB connection after driver installation
The USB connection on the AsteRx-U functions as network adapter and the DHCP server
running on the receiver will always assign the AsteRx-U the IP address 192.168.3.1.
To connect to the AsteRx-U, you can then simply open a web browser using the IP address
192.168.3.1 as shown in Figure 3-6.
Figure 3-6: Connect to the Web Interface of the AsteRx-U over USB using the IP
address 192.168.3.1 on any web browser
18

3.3. CONNECTING TO THE ASTERX-U VIA THE WEB INTERFACE
3.3.2 Using the Ethernet cable
Step 1: Connect the combined USB/Ethernet cable
Connect the combined USB/Ethernet cable shown in Section 2.4.1 between a LAN network
and the connector labelled ‘ETH USB‘on the rear panel of the AsteRx-U indicated in
Figure 3-7.
Figure 3-7: Rear panel USB and Ethernet socket
Step 2: Open a web browser and connect to the AsteRx-U
By default, the AsteRx-U has a DHCP address ‘http://Asterx-U-xxxxxxx’, where xxxxxxx are
the 7 digits of the AsteRx-U serial number. The serial number can be found on a sticker on
the corner of the outer casing of the receiver. Figure 3-8 shows a screenshot of an Ethernet
connection to a receiver with serial number 3011881 using ‘http://asterx-u-3011881’.
Figure 3-8: Connecting to the Web Interface via Ethernet
19

3.3. CONNECTING TO THE ASTERX-U VIA THE WEB INTERFACE
3.3.3 Over WiFi
The Web Interface can also be accessed over a WiFi connection. On your PC or tablet,
search for visible WiFi signals: the AsteRx-U identifies itself as a wireless access point named
’AsteRx-U-serial number’. The serial number of the AsteRx-U can be found on an identification
sticker on the receiver housing. Select and connect to the AsteRx-U as shown in Figure 3-9.
Figure 3-9: Select the AsteRx-U from the list of detected wireless signals and
connect
When your PC is connected to the AsteRx-U WiFi signal, you can open a web browser using
the IP address: 192.168.20.1 as shown in Figure 3-10.
