Quick Start Guide REX 100 WAN | Wi-Fi 3
1. Introduction
The REX 100 is an industrial router suitable for worldwide remote access to IPv4-
enabled devices (PLCs, HMIs, IP cameras, etc.). This Quick Start Guide explains the
basic settings in the myREX24 portal and shows how to transfer the conguration
made there to the REX 100 unit.
2. Preparing the REX 100 unit
2.1 Safety instructions
Assembly, installation and commissioning of the router may only be carried out by
qualied personnel. The respective national safety and accident-prevention regula-
tions must be complied with. The router was constructed using state-of-the-art tech-
nology and the recognized safety-related rules (see declaration of conformity). The
router was designed solely for operation in the switch cabinet and at safety extra-low
voltage (SELV) in accordance with IEC 60950/EN 60950/VDE 0805 and may only
be connected to devices which fulll the conditions of EN 60950. The router is only
intended for use inside buildings, i.e. it is not intended for outdoor use.
Electrostatic discharge! Comply with the required precautionary measures when
handling components at risk from static electricity (EN 61340-5-1 and IEC 61340-5-1).
2.2 Installation position/Minimum clearances
The router was designed to be mounted on DIN rails (as per DIN EN 50 022) and in-
tended for installation in switch cabinets. Installation and mounting must take place
in accordance with VDE 0100/IEC 364. The router may only be installed in a vertical
installation position.
Important advance information: Please use the most current version (V3.7R1.0 or
higher) of the “shDIALUP” dial-up software for commissioning. You can download it
from www.helmholz.de.
For a successful and secure connection with the myREX24 V2 portal, the rmware statuses
of all REX 100 routers should be checked regularly and, when necessary, be updated to the
most current status through the system settings of your myREX24 account.

2.3 Terminals and interfaces
Rigid copper wires with a max. diameter of 1.5 mm² can be clamped onto the
provided connector plug. Network cables corresponding to at least category 5/5e
(CAT-5) should be connected to the RJ-45 sockets.
Internal switch functions are active even if the REX 100 router is not connected to
the Internet.
The PWR LED lights up when the 24-volt supply voltage is applied.
The boot process starts following the internal system check, which is indicated by
the blinking RDY LED. The REX 100 is ready for operation as soon as the PWR LED
and RDY LED light up continuously. (duration: approx. 90 sec.)
Connection FE is for the functional ground. Connect this properly to the reference
potential.
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
myREX24 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.

3. Access to the myREX24-V2 portal
The REX 100 can be fully congured in the shDIALUP dial-up software through
the myREX24 V2 portal. This software, as well as other documents with supple-
mentary example applications, can be downloaded from the download area of
www.helmholz.de at any time and installed under a Windows operating system.
You can also administer your projects and the conguration of your REX routers
through an HTTPS-secured direct call from your browser. Use the following URL for
this purpose: https://v2.myREX24.net.
Use the myREX24 V2 portal access data available to you for logging in. The various
ways to transfer a conguration you have created to the REX 100 are described
below. Establishing a secure VPN to a REX router can then only occur using the
shDIALUP remote client software. You can nd further information in the manual for
the myREX24 V2 portal.
3.1 Logging in to the myREX24 V2 portal server
Install the shDIALUP software with administrative rights under a Windows operating
system. After opening the program, select the “V2.myREX24.net” server in the top
menu bar and then log in to the myREX24 V2 portal with
your access data.
You should only register at www.myREX24.net if you don’t yet have a myREX24 V2
portal account or have not received user access from a myREX24 account administra-
tor. Fill out the required elds there. After your data is checked by our service team
(Mon. to Fri., 8 a.m. to 5 p.m. CET), you will receive two separate e-mails with the
access data. One e-mail contains the user name, and the second the password.
Notes:
-Alternatively, the login page can also be accessed at https://v2.myrex24.net.
Any current browser can be used for this.
-Your login name can be comprised of your user name and company name
separated by the @ symbol, for example. Example: admin@helmholz
-Following the initial login, you will be prompted to register a new,
individual password for your account.
-As the account administrator, you can create and administer additional
users after logging in to the myREX24 V2 portal if necessary.

4. Initial router conguration via the
myREX24 V2 portal
The following information describes the basic conguration steps required in order
to set up a REX router for a VPN connection. A description of the extended functions
can be found in the online help or in the manuals/white papers. You can go to the
online help in the myREX24 V2 portal using the question mark symbol in the lower
left-hand area of the screen ?. When you log 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 Creating a new project
A project is the highest level for carrying out the following tasks:
-Device administration
-Remote maintenance
-Monitoring and alarms
-Data logging
-Visualizations
Initially, at least one new project must be created in which a router is assigned.
Navigate to the Administration section using the following symbol
(the tutorial also brings you to this point).
A unique project name is now issued in this menu.
Additional account users, if created, can be assigned to this project
on the “Access” tab.

Quick Start Guide REX 100 WAN | Wi-Fi 9
4.2 Creating a new device
A router can be added to 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 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 sufcient for 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, the correct device type (matching the device order number) must
be selected. A unique, freely selectable name should be assigned to this router.
Only numbers and letters may be used (0 to 9, A to Z, a to z and no spaces or special
characters).

Quick Start Guide REX 100 WAN | Wi-Fi10
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. If necessary, modify the IP address and subnet mask according
to the specications from the machine network to be maintained
remotely.
-WAN The required information for the DHCP or static IP settings is provided
by the respective network administrator. DHCP is preset at the factory.
-Wi-Fi
Enter the Wi-Fi-specic access data (only 700-875-WIF01). The corre-
sponding data provides you with the responsible network administrator.
Note: If you use DHCP, make sure that the DHCP server does not assign an IP address
the WAN interface that is already active on the LAN side. IP addresses from two different
subnets must be assigned to each router’s LAN and WAN interfaces.
4.3.3 Step 3 “Conguration” – Coupling/pairing the router
with the portal
The basic parameters of the minimum conguration of the REX 100 are now stored
in the portal account and must now be transferred to the device (see Chapter 5).
Note: We recommend the “Download conguration to PC” variant for the initial
conguration.
