2 SAFETY GUIDELINES

Please read the following safety guidelines carefully! In case of property or personal

damage by not paying attention to this manual and/or by incorrect handling, we do not

assume liability. In such cases any warranty claim expires.

• The power supply should be in immediate proximity to the device.

• The power supply must provide a stable output voltage between 11 – 28 VDC. The out-

put power should be at least 2.5 W.

• Please pay attention that the power cord or other cables are not squeezed or damaged in

any way when you set up the device.

• The installation of the device should be done only by qualified personnel.

• Discharge yourself electrostatic before you work with the device, e.g. by touching a

heater of metal, to avoid damages.

• Stay grounded while working with the device to avoid damage through electrostatic dis-

charge.

• The case of the device should be opened only by qualified personnel.



3 HARD- AND SOFTWARE REQUIREMENTS

To work with the Web Application Gateway IGW/935 a software development environment

is needed.

This development environment requires a PC as development system to access the Web Ap-

plication Gateway via TCP/IP. This PC should comply with the following hard- and soft-

ware requirements:

• Windows 7 or Windows 8

• Web browser (e.g. Firefox, Chrome)

• Telnet/SSH client (e.g. TeraTerm)

• FTP client (e.g. FileZilla)

• 10/100 Mbps Ethernet network controller and TCP/IP configuration

• CD-ROM drive



4 CONNECTIONS

For a quick and easy start with the Web Application Gateway IGW/935 there are a few cable

connections necessary. The following chapters describe how these connections have to be

made.

4.1 Ethernet Link

The Ethernet link can be made on two ways: with an Ethernet cross-over cable or with two

standard Ethernet patch cables and a hub or switch. When using a hub or switch please con-

nect it between the host PC and the IGW/935 like shown fig. 2.

Figure 1: Ethernet link with cross-over cable

Note: For the Ethernet connection in fig. 1 it is absolutely required to use a

cross-over cable. Do not use an ordinary patch cable. Ethernet patch and cross-over

cables are in most cases visual indistinguishable. But the internal wiring is fully dif-

ferent. Mixing up these types of cables leads to LAN errors. Hence pay attention to

the label of the cable or packing.

Figure 2: Ethernet link with hub or switch



4.2 DVI/HDMI Video Link

Use the DVI/HDMI video cable to connect an external monitor device with the IGW/935

like shown fig. 3.

Figure 3: DVI/HDMI video link



4.3 RS485 Serial Port COM1

To create an RS485 serial link on port COM1 of the Web Application Gateway IGW/935

connect an RS485 device like shown in the fig. 4.

Figure 4: RS485 link on serial port COM1

Terminal Signal

A1 COM1 RS485 Serial Port RX /TX+

A2 COM1 RS485 Serial Port RX /TX-

A4 Ground

Table 2: Screw terminal COM1

* Please note: The RS485 (officially called TIA/EIA-485-A) connection between

your IGW/935 and the field devices needs termination resistors on both ends for

proper operation. The IGW/935 does not offer internal termination resistors. Please

make sure, that the RS485 cable connection is equipped with external termination re-

sistors.



4.4 Power Supply

The Web Application Gateway IGW/935 needs a supply voltage of 11 – 28 VDC to work.

Connect the cables of the plug-in power supply to provide the system with the necessary

power like shown in fig. 5.

Figure 5: Power supply for the Web Application Gateway IGW/935

Terminal Signal

A3 Vin (11 .. 28 VDC)

A4 GNDin

Table 3: Screw terminal power

CAUTION: Providing the Web Application Gateway IGW/935 with a higher voltage than

the regular 11 – 28 VDC could cause damaged device components!

CAUTION: Do NOT turn on the power supply while connecting the power adapter cable

with the Web Application Gateway IGW/935. This could cause damaged board components!

First connect the power adapter cable and THEN turn the power supply on.



5 OPERATION

5.1 Booting the IGW/935

Just power up the IGW/935 and the boot process starts immediately. The IGW/935 boots

thereby an embedded Linux out of its Flash memory. This may take up to one minute.

5.2 Checking the IP Address of the IGW/935

After the boot process is finished, you have to check the current IP address, which is neces-

sary to access the IGW/935 via a Telnet client or a web browser.

Please open in Windows „Control Panel > Network and Internet > View network com-

puters and devices“.

Figure 6: Selecting the IGW/935

Now right-click on the IGW/935 to open the properties dialog, where you can see the cur-

rent IP address of the IGW/935 like shown in fig. 7.

A double-click on the IGW/935 opens the SSV/WebUI demo page in a web browser.



Figure 7: The properties dialog shows the current IP address

Now you are able to access the IGW/935 via a Telnet client or a web browser.



5.3 Testing the TCP/IP Communication

To test the Ethernet connection on the basis of TCP/IP-protocols between the IGW/935 and

the host PC use the TCP/IP-utility program ping. Open a DOS window on your host PC (you

find it in the Windows Start menu) and enter:

ping 192.168.0.183 *

Directly after this command test data is send from the host PC to the IGW/935 via Ethernet

LAN. The IGW/935 must answer on the same way within a certain period of time. Fig. 8

shows the entry of the command as well as the successful execution. In case of an error ping

reports a timeout.

Figure 8: Communication check via ping

The IGW/935 must answer every ping. Otherwise an error will occur. In this case you have

to check all parts of your LAN connection, including the IP address of the IGW/935.

*Note: We assume here that the IGW/935 has the IP address 192.168.0.183. Please

refer to chapter 5.2 for the current IP address. If your device has a different IP ad-

dress, you must regard this for the ping parameter.

Once the ping was successful, you are ready to access the IGW/935 with a web browser or a

Telnet client.



5.4 Accessing the SSV/WebUI WebConfig

To open the login page of the SSV/WebUI WebConfig enter the current IP address of the

IGW/935 in a web browser, e.g.:

http://192.168.0.183:7777 *

The username is admin, the password is ssvadmin.

Figure 9: Login page of the SSV Web WebConfig



dress, you must enter this address in the web browser. The last part “:7777” (the port

number) is important and must NOT be changed!



5.5 Changing the IP Address

To change the IP address of the IGW/935 enter the SSV/WebUI WebConfig and choose

from the menu “Network > LAN”. In this section you can configure the LAN settings.

Figure 10: LAN settings

• Enable/Disable interface LAN: Enable or disable interface LAN.

• IP address configuration: Manual device configuration or through DHCP server.

• IP address: IP address of the device.

• Subnet mask: Subnet mask of the local network.

• Enable/Disable alias IP address: Enable or disable the alias IP address.

• Alias IP address: Secondary static IP address for the same interface.

• Alias subnet mask: Subnet mask of the alias network.

Note: Please be very careful with IP address changes. If you enter an incorrect IP ad-

dress or parameters it might be impossible to reach the SSV/WebUI WebConfig

again. In this case please start a new UPnP device search with your Windows PC.



5.6 Accessing the SSV/WebUI Demo Page

To open the demo page of the SSV/WebUI enter the current IP address of the IGW/935 in a

web browser, e.g.:

http://192.168.0.183 *

Figure 11: Demo page of the SSV/WebUI



dress, you must enter this address in the web browser.

The same demo page is visible if an external video monitor is connected to the IGW/935

DVI/HDMI video interface. In this case the IGW/935-internal WebKit GTK+ web browser

shows the demo in full screen mode with a resolution of 1280 x 800 (16:10).



5.7 Access via Telnet

To access the IGW/935 via Telnet please open a Telnet client program (like e.g. TeraTerm)

on your host PC and enter the current IP address* of the IGW/935 to activate a Telnet ses-

sion.

In the upcoming Telnet window you can login with the username root and the password

root.

Now you can enter any Linux commands, which will be executed by the IGW/935 operating

system.

Figure 12: Access via Telnet client

*Note: Please refer to chapter 5.2 for the current IP address of the IGW/935.



5.8 Access via FTP

The IGW/935 comes with a pre-installed FTP server, which allows the file transfer via

Ethernet between a PC and the IGW/935. To access the IGW/935 via FTP use an FTP client

like e.g. FileZilla.

Figure 13: FileZilla as FTP client to access the FTP server

Use for the FTP login the current IP address* of the IGW/935, the username root and the

password root. With this login you have FTP read/write permission in the file system.

The default setting of the root file system after the boot process is read-only. There are only

three exceptions, which are shown in the following table:

Directory Remark

/flash R/W directory, non-volatile memory within Flash

/home/root R/W directory, RAM disk, volatile memory

/var/volatile R/W directory, RAM disk, volatile memory

Table 4: R/W directories in the file system

The read-only restriction protects all files of the file system. Under ordinary operating condi-

tions it is not possible to overwrite or delete a file which is necessary for the eSOM/3517

within the IGW/935.

To disable the write protection just login with the username root and the password root and

enter the following command:



mount / -o remount,rw

This command „mounts„ the file system as read/write. All files are now writable and delet-

able. Please pay attention not to damage important system files! With the command

mount / -o remount,ro

the system is set back to the read-only initial condition after the boot process.

*Note: Please refer to chapter 5.2 for the current IP address of the IGW/935.
