2. Preparing the REX 100 unit

2.1 REX 100 WiFi

Connect a WiFi-compatible antenna (2.4 GHz) and ensure that a radio connection to

a WiFi network is possible. Antennas are available separately as accessories.

The LAN ports are also active when the REX 100 router has no connection with the

Internet.

2.2 REX 100 WAN

Connect the WAN interface of the REX 100 (P1 WAN) with a patch cable with the

higher level (company) network/router. The LAN ports P2 to P4 are available for

connection to the machinery network.

1. Introduction

The REX 100 is an industrial router suitable for worldwide remote access to IPv4-en-

abled devices (PLCs, HMIs, IP cameras, etc.) It is mounted on the DIN rail. This Quick

Start Guide explains the basic conguration of the REX 100 router. The conguration

is created in the myREX24 V2 portal and then transferred to the REX 100.

Important advance information: Please use the latest version of the dial-up software

“shDIALUP” (as of version v3.7 R1.0). You can acquire it as a download at www.helm-

holz.de. For successful connection with the myREX24 V2 portal, REX 100 routers require

at least the rmware status V1.5.0 or newer.

2.3 Power supply

The REX 100 must be supplied with 24 V DC at the wide range input 18 ... 30 V DC

via the provided connector.

Note: The housing of the REX100 is not grounded. Please correctly connect the functional

grounding connection (FG) of the REX 100 WAN (700-875-WAN01) and REX 100 WiFi

(700-875-WIF01) with the reference portal.

2.4 Digital inputs IN1 and IN2

The alarm inputs can be activated with potential-free switches, buttons or relay

contacts.

IN1 can, for example, be used for the VPN establishing of connection with the my-

REX24 portal. An alarm can be triggered with the IN2.

The use of both inputs for the alarm is also possible. The con guration of the alarms

takes place via alarm management in the myREX24 V2 portal.

2.5 Boot procedure

The green PWR LED lights up when the supply voltage is switched on.

The boot process starts following the internal system check (duration of approx. 25

sec.), which is indicated by the blinking RDY LED (for approx. 90 sec.).

The REX 100 is ready for operation as soon as the RDY LED lights solid.

Quick Start Guide REX 100 WAN | WiFi

3. Access to the myREX24-V2 portal

The REX 100 can be fully congured using the myREX24 V2 portal.

A secure connection with the portal is required to this purpose:

-The remote client software shDIALUP allows you to undertake administration in the

myREX24 V2 portal and the VPN establishing of a connection with an REX router.

You can nd the software

(shDIALUP) in the download area under www.helmholz.de. There you can also

download further documents with additional example applications at any time.

-Alternatively, you can also create the conguration with an HTTPS-secured direct

call-up from your browser. The call-up is realized with the following URL: https://

v2.myREX24.net. However, remote maintenance via VPN tunnel cannot be set up

via the browser.

Always use your myREX24-V2 portal access data to log in.

3.1. Registration

If you don’t yet have a myREX24-V2 portal account, you can register under http://

www.myREX24.net.

Fill out the required elds there. After your data is checked by our service team

(Mon.-Fri. 8 a.m. to 5 p.m. CET), you will receive two separate e-mails with the

access data.

The rst e-mail contains the user name, the second the password.

Quick Start Guide REX 100 WAN | WiFi

3.2 Logging in to the myREX24 V2 portal

Once you install and start the shDIALUP software, you can use your login data to log

in to the myREX24 V2 portal.

Select “V2.myREX24.net” in the server list.

Notes:

-Alternatively, the login page can also be reached under: https://v2.myrex24.net. Any

up-to-date browser can be used for this purpose. Chrome

and Firefox are recommended.

-Your login name is composed of a user name preceding the @ character and the name

of your company. Example: User@Account

-Please change your password after logging in for the rst time.

-If necessary, you can also create and administer additional users after logging into the

myREX24-V2 portal.

3.3 Navigation in the portal

Once a user has logged in for the rst time, he or she is guided through a tutorial.

The navigation, basic settings, and the change from the Simplied to the Extended

view is shown.

3.4 Simplied and extended view

The conguration of the devices can be carried out in the myREX24 V2 portal in two

views: simplied and extended.

Standard is the simplied view, but one can switch between the views at any time.

The simplied view is used for the most part in the subsequent course of the Quick

Start Guide. The extended view is also presented in some places for purposes of

illustration.

4. Initial REX conguration via the myREX24-V2 portal

The following information describes the basic conguration steps required in order

to be able to set up a REX router for a VPN connection.

A description of the extended functions can be found with the online help or in the

manuals/white papers. You can go to the online help

in the myREX24 V2 portal via the question mark symbol in the lower left area of the

screen .

When you have logged in for the rst time, the myREX24 portal guides you through

a brief tutorial.

Please change the password for your myREX24 account following the tutorial.

4.1 Create new project

A project is the highest level for carrying out the following tasks:

-Device administration

-Remote maintenance

-Monitoring and alarms

-Data protocoling

-Visualizations

Each router is assigned to a project. In order to create a new project,

please click on Administration.

The tutorial also leads to this point .

The project is now assigned a name.

Quick Start Guide REX 100 WAN | WiFi

4.2 Create new device

A router can be added in the tree structure using the plus symbol or with a right-

click of the mouse. If a project does not yet have a router, the same function is made

available in the main view by way of the green button “Create new device”.

Clicking on the respective button starts the conguration assistant, which guides the

user through the settings.

4.3 Congure REX 100 (connection data)

Three simple steps are adequate for the minimal conguration of the router:

-Selection of the device type

-Network settings

-Transfer of the conguration to the REX router

4.3.1 Step 1 “Device” – Selection of the type and name

In the rst step, only the selection of the router type and the assignment of a clear

name is necessary.

The name can be selected freely, but only numbers and letters are allowed

(0 to 9, A to Z, a to z, no spaces).

Quick Start Guide REX 100 WAN | WiFi

4.3.2 Step 2 “Internet” – Network settings

In step 2, the network conguration for the LAN and mobile WAN side of the device

is dened.

-LAN All REX 100 routers come with the IP address 192.168.0.100/24 as a

default. Modify the IP address and the subnet mask in keeping with the

machinery network.

-WAN Here the data are entered for the WAN connection (company network

for the machine) – DHCP or static IP address.

The corresponding data provides you with the responsible network

administrator.

-WiFi Enter the WiFi-specic access data (only 700-875-WIF01).

The corresponding data provides you with the responsible network

administrator.

4.3.3 Step 3 “Conguration” – Transfer of the conguration

The minimal conguration is now complete and must be transferred to the REX 100.

The conguration is downloaded with a click on the download button and can be

transferred with a FAT-formated USB stick to the REX router. This step is described in

chapter 5.1 (page 12).
