    Before getting started: Please use the most current version (as of v3.7.0) of the dial-up REX 300 is an industrial router for global remote access to PLC, HMI, IP cameras, etc. software "shDIALUP" for commissioning. You can acquire it as a download at www.

  • Page 4: Access To The Portal

    2.4 Power supply and ports The REX 300 must be supplied with 24 V DC at the wide range input 10 – 30 V DC. Rigid copper wires with a max. diameter of 1.5 mm² can be clamped onto the provided connector plug.
  • Page 5 One e-mail contains the user name, the second the password. The software required for establishing the connection with the myREX24-V2 portal (shDIALUP and shCHECK) can be found in the download area under www.helmholz. de. There you can also download further documents with additional example appli- cations at any time.

    - The name must start with a letter. Umlauts, special characters and spaces are general- ly not permitted. Double designations are also not possible in the "Name" fi eld. - The serial number always starts with the letter "R", followed by eight numbers (0-9). After saving your information, you will be automatically forwarded to the device settings. Quick Start Guide REX 300...

  • Page 8: Router Configuration Transfer Options

    3. Configuration via LAN The configuration is transferred via a local LAN connection of the computer on which shDIALUP is running (see page 18, chapter 5.3). You can select this procedure if the REX 300 router can be reached directly through LAN. The IP address settings of the network adapter are not relevant. Note: We recommend the "Configuration per LAN" variant for the initial configuration. Quick Start Guide REX 300...

  • Page 11 4. Automatic synchronization and prepare for synchronization 5.2.1 File the REX 300 confi guration in the portal As soon as the REX 300 router has established an Internet connection with the por- tal, the REX 300 is verifi ed for your account on the basis of its unique serial number. The confi guration data is then transferred automatically to the REX 300. This method is also ideal in the event that you need to carry out retroactive changes to the device settings.
  • Page 12 5.2.2 Calling up the "First Start Assistant" through the browser You can also determine the Internet access of the REX 300 directly in the web inter- face of the router via the "First Start" website. This is relevant in the event that the REX 300 has not yet been confi gured through one of the other confi guration paths (with the PC via LAN or via USB stick). In the delivery condition, the REX 300 has the LAN IP address 192.168.0.100 with the subnet mask 255.255.255.0. In order to reach the REX 300 through your local LAN connection, the network setting of your PC may need to be adjusted.
  • Page 13 Create Internet connection with internal analog modem: If you are using a REX 300 router with an internal analog modem, you will need to store the login information of an "Internet by call provider" in the REX 300. The device will provide suggested login information for Internet access by default. It is, however, recommended that you enter a provider of your choice here, as using the default type of connection will entail additional fees and the availability of the suggested provider is only guaranteed in Germany. The default X3 AT command initializes the internal modem to not wait for a dial tone (private branch exchange mode) when dialing. In most cases, this setting does not...
  • Page 14 To this purpose, the WAN interface must be connected with the customer server/DSL modem. If you select "DHCP," you do not have to configure any WAN settings. Note: Please make sure to either disable the MAC address filtering on the DSL modem and/or external firewall, or to approve the REX 300 MAC address there. The values for the statically set WAN interface are established by the responsible network administrator. Where applicable, settings for access through proxy servers will also need to be stored in the WAN configuration. Confirm with "Next".

Automatic download of the confi guration If the REX 300 is able to establish an Internet connection, the router will connect to the myREX24 portal and verify itself using its serial number. The successful establishment of a connection is indicated on the REX 300 by a slowly fl ashing "Con VPN" LED (see LED description on page 26, chapter 11).
  • Page 16 5.2.3 Synchronization of the portal confi guration As soon as the REX 300 has logged into your account in the myREX24-V2 portal, you can transfer retroactive changes to the REX 300 at any time with "Synchronize". Where there is an existing portal connection, the REX 300 checks cyclically whether there is a new confi guration available for its serial number and then loads it auto- matically. When, for example, you have edited the LAN IP address, the "Device...
  • Page 17 The status page on the REX 300 router's web interface will show the router's connection status and active configuration data. To this purpose, enter the LAN IP address of the REX 300 into the address bar of a browser. The TCP/IP address of your network adapter must be located in the same IP subnet. Authenticate yourself with the standard user: helmholz and the password: router.

Transfer the configuration In order to transfer the configuration from a PC through a local LAN connection, the configuration PC must allow for two simultaneous network connections: 1. The PC must be active in the Internet with the shDIALUP software 2. The PC and the REX 300 to be configured must be connected in the same network via LAN. In practical terms this is possible as follows: - PC with two network adapters/Ethernet connections...

    In order to end the connection of a remote access, please click the in the meantime yellow and animated connection button and then confi rm the disconnection of the remote connection. Once a connection to the REX 300 has been established, all the IP packets that are valid for the applicable LAN network on the system side will be forwarded. Further parameters for the VPN-IP/IP subnet are also shown in the lower status bar for infor- mational purposes.

    Background - shDIALUP and the REX 300 establish an outbound TCP connection with the address v2.myrex24.net (5.39.123.21). - In order to be able to establish a secure connection to the myREX24 server with shDIALUP or REX 300, at least one of the following TCP ports (80, 1194, or 443) re- quired for the VPN tunnel must be open. Port 80 is locked in the example shown to the right. However, the connection with the myREX24-V2 server can be established via ports 443 or 1194. Please clarify which settings are required in advance with the IT department on site.

You can also use alternative e-mail servers to send e-mails. 7.5 Device configuration: Services – NTP server For purposes of time synchronization of the REX 300, this carries out a comparison at regular intervals. Where necessary, you can individually set the preset NTP server and the interval. Quick Start Guide REX 300...

    - The LAN port is suitable for 100 Mbps and full duplex operation, and supports au- to-crossover and auto-negotiation. No special PROFINET functions are supported. - When connecting additional Ethernet participants (PLC/panel) with the REX 300, it must be ensured that the IP addresses of the devices lie within the address range of the LAN interface of the REX 300.
