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

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.

Quick Start Guide REX 100 WAN | WiFi

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.
