Installation, operation and service manual M2019/02a
3.4. INTERNET CONNECTION OPTIONS
To make of the advantages of central reading system CRS 40, it is necessary to connect the reading network
to the Internet. The CRS unit B therefore contains an integrated standard RJ45 Ethernet interface. Using this
interface, it can be connected directly into the domestic cabling structure (type CAT5 or higher - cable with
RJ45 connector). It is also possible to use a Wi-Fi USB power adapter or GSM modem.
The control unit B waits for assignment of the dynamic IP address V4 through protocol DHCP, which is
commonly used for this purpose. When the unit is required to use the address assigned by the Internet
provider, it must be specified in the Settings (more in chapter 10.5 System parameters setting).
Possible means of connecting to the Internet:
• via Ethernet network
• via Wi-Fi network (Wi-Fi USB adaptor must be used)
• via mobile network (USB GSM modem must be used)
Using various connection methods depends on the circumstances of a particular apartment building. If in
doubt, contact your Internet provider.
If the computer is correctly connected to the Internet and set up, it automatically initiates an encrypted
connection and allows connection with the control computer.
For more information, see chapter 5.1. Installing the unit B.
