2. Preparing the REX 100 unit
2.1 REX 100 WiFi
Connect a WiFi-compatible antenna and ensure that a radio connection to a WLAN
access point (e.g. DSL modem) is possible.
(Antennas are available separately as accessories)
2.2 REX 100 WAN
Connect the WAN port of the REX 100 (P1 WAN) to the network or DSL modem
being used to establish an Internet connection.
1. Introduction
Before getting started:
For commissioning please use the latest version (as of v3) of the dial-up software
“shDIALUP”.
Write down the serial number and MAC address of your REX router before installing the
router in your system. You will need the serial number in order to congure the device!
The REX 100 is an industrial router designed to be installed on DIN rails and is suit-
able for worldwide remote access to IP-enabled devices (PLCs, HMIs, IP cameras, etc.)
This Quick Start Guide goes over the basic settings in the myREX24 portal and shows
how to transfer the conguration made there to the REX 100 unit.
2.3 Connection
Now connect a supply voltage of 18–30 V DC to the provided connector for all
device variants.
There is also a connection for the functional earth (FE). The connection of a function-
al earth is recommended.
2.4 Optional wiring of IN1 and IN2
IN1: The establishing of the connection to the myREX24 server can, for example, be
activated by an externally installed switch.
IN2: When the alarm management in the device has been activated and congured,
e-mails, for example, can be sent through an externally installed button or relay
contact.

3. Creating a REX 100 conguration in the myREX24
portal
REX 100 routers are fully congured using the myREX24 portal. A completed cong-
uration le can be transferred to the actual REX 100 unit in a variety of ways.
3.2 Log in to the myREX24 portal
Once you install and open the shDIALUP program, you can use your login data to
log in to the myREX24 portal.
Note: Your login name is composed of a user name preceding the @ character and the
name of your company.
Example: admin@helmholz
Other users can be created and administered after you log onto the myREX24 portal.
3.1 Registration
If you do not yet have a myREX24 account, you will rst have to visit www.myREX24.
net and register under “Request access.” Make sure to ll out all mandatory elds.
Once you submit the form, you will receive an e-mail containing your login data.
You can download the software necessary for establishing a connection with my-
REX24-Portal (shDIALUP and shCHECK), as well as other documents with supplemen-
tary example applications anytime from the download area under www.myREX24.
net and www.helmholz.com.

3.3 Creating a router con guration
The following information describes the con guration points required to establish
a VPN portal connection. For a more detailed description of the advanced functions
and con guration options available, please use the portal’s online help.
Note: You should always individualize your login information (user names/passwords).
All relevant explanations can be found in the online help.
Once a connection to the myREX24 portal is successfully established, a new browser
window with your myREX24.net online account will open. Create a new device in
the “Machines” menu.
Click the icon to get to the next submenu.
Note: The device name must start with a letter. Umlauts, special characters and spaces
are generally not permitted. In addition, every device name must be unique.
The description page for the device you just created will appear now. The entry of
location and contact information data is optional.
The “Change VPN Password”  eld requires no entry. The password is generated
automatically.
To make sure that the con guration is sent to the right device, you will need to enter
the REX 100 router's serial number. The purpose of the additional description  eld is
to make it possible to distinguish between several remote servicing units internally.
Open the “Network” tab without clicking "Save".

Quick Start Guide REX 100 WAN | WiFi

All REX 100 routers come with a LAN-side IP address of 192.168.0.100/24 as a
default. Modify the IP address and the subnet mask in keeping with the specications
from the machinery network.
If you want to connect additional TCP/IP components to the REX 100 LAN interface
for remote servicing purposes, this IP address will also be the default gateway for the
connected devices (see page 16).
The input eld WiFi Settings is only displayed for the device versions with WiFi. The
WLAN-specic access data for an access point must be entered here. The responsible
network administrator should be able to provide you with this data.
Open the “Internet” tab without clicking “Save”.
Under "Connect to the server", select the actions with which this device should
connect to your myREX24 account.
When using static IP addresses, the customer specications for the subsequent router
location must be used for the gateway, DNS server, and VPN port.
Prior to dening a pre-selectable VPN port, clarify whether this is also open on the
system side at the customer location (also see the chapter 5.2 "Tips and Tricks", page
15).
You have now congured the basic settings and can click on "Save" to proceed to
transfer the conguration to the REX 100 unit using one of the options available in
the menu (see chapter 4, page 7).
In the event that the dialog for "Submit to Device" appears automatically, you can
cancel this dialog and call it up later when needed.
Note: The myREX24 portal’s online help provides information on the function of the
advanced settings. If you enable DHCP, make sure that the DHCP server does not assign
the WAN port an IP address that is already in use on the LAN side. IP addresses from two
different subnets must be assigned to every router's LAN and WAN ports.

4. Router conguration transfer options
Once you have created a conguration, you can click the oppy disk icon in order to
select one of three transfer methods.
1* Download conguration to PC
Save the conguration le and then use a USB stick to transfer it to the REX 100 unit
(see chapter 4, page 8).
Choose this option if the REX 100 router cannot be reached through the local net-
work (LAN) or through
the Internet when it is rst being set up.
2* Transfer conguration to CTM
The conguration is downloaded from the myREX24 portal using the REX 100
router's Internet connection (CTM = Conguration Transfer Manager; see chapter
4.2, page 9).
This Internet transfer method will become the default conguration option as soon
as the REX 100 router has established a connection to the myREX24 portal. When the
REX 100 has a connection to the myREX24 portal, the CTM is automatically used for
all subsequent conguration changes.
3* Transfer conguration to device
The conguration is transferred via a local LAN connection of the computer on which
shDIALUP is running (see chapter 4.3, page 14).
You can use this option if the REX 100 router can be reached directly through the
local network (LAN).

4.1 Transferring the conguration using a USB ash drive
Use the USB-based parameter conguration method if the REX 100 router cannot be
reached either through the local network (LAN) or through the Internet.
In the myREX24 portal, go to the "Device Administration" page and select the
"Download to PC" option.
Once the le has been stored on the local computer, carry out the steps as described
in chapter 9 "Load conguration/rmware update from USB stick" on page 18.

4.2 Conguration Transfer Manager (CTM)
The Conguration Transfer Manager makes it possible to transfer the conguration
to the REX 100 router once the router has established an Internet connection to the
myREX24 portal.
If the REX 100 unit has a connection to the myREX24 portal, it will check whether
there is a new conguration available for its serial number. If there is one, it will load
it automatically. This method is ideal for retroactive changes to the conguration.
Note:
-The CTM function is only supported as of version 3 of the dial-up software "shDIALUP".
- In order to be able to transfer the conguration, the Conguration Transfer Manager
needs an Internet connection established using a WAN/WLAN network. If you are
commissioning your REX 100 unit for the rst time, this can be commissioned directly
on the REX 100 router through the "First Start" webpage.
4.2.1 Establishing an Internet connection through the "First Start" website
If you have not yet congured your REX 100 router using one of the other congu-
ration methods (directly on the computer or using a USB ash drive), you can also
establish an Internet connection for the commissioning directly with the REX 100
router's web interface at the "First Start" website.
If the REX 100 can already set up an Internet connection, please continue to chapter
4.2.3 "Automatic download of the conguration" on page 13.
Commissioning via the "First Start" website presumes that the REX 100 can be ad-
dressed in the local network under its default IP address. REX 100 routers come with
a default IP address of 192.168.0.100 (subnet mask: 255.255.255.0).
In order to be able to reach the REX 100 router, the PC network adapter must also be
set to the IP address space and subnet of the router.
The device with serial number must be created in the myREX24 portal for successful
commissioning.

Quick Start Guide REX 100 WAN | WiFi

Your IP address must lie within the address range "192.168.0.x". The subnet mask
must match the subnet mask used by the REX 100 unit (default: 255.255.255.0).
Note: Make sure that there are no address space conicts with any other network ports
(do not assign the same IP address more than once). If there are, you will not be able to
communicate with your REX 100 unit properly.
Open the properties of your LAN connection in order to set the PC network card to
the IP address range and the subnet of the router.
Windows¹ XP:
Start -> Settings -> Control panel -> Network connections.
Windows¹ 7:
Start -> Control panel -> Network and sharing center -> Change adapter settings
Open the Properties dialog box for the network connection that you want to use in
order to establish a connection to your REX 100 unit. To change your computer's IP
address, select "Internet Protocol (TCP/IP)" and click on the "Properties" button.
When your PC network card has accepted the new settings, start a browser (Firefox,
Chrome, Opera) and enter the IP address of the router in the address line (URL) as
follows: http://192.168.0.100.
Enter the following standard login data for the login to the REX 100 required now:
User name: helmholz
Password: router
The Internet connection path of the REX 100 is now dened uniquely at the "First
Start" website.
Note: Please note that the login data must be changed for your security after the router
is set up. To change them, go to the conguration menu on the myREX24 portal.
