2500C-2572-B Quick Start Guide
The 2572-B is shipped from CTI with the IP address set to 169.254.1.1 and the subnet mask set to 255.255.0.0. To
connect to the module, you must ensure that your PC has an IP address that is on the same IP network and is not the
same as the module IP address.
One method of providing your PC with compatible IP address is to use Windows Control Panel (or Windows Settings in
Windows 10) to configure a static IP address. In this case, the first two octets of the PC IP address must be 169.254,
the last two octets of the PC IP address must not be 1.1, and the PC subnet mask must be set to 255.255.0.0. For
example, an IP address of 169.254.1.2 would work.
Note:
Holding down the reset button for 10 seconds or more will cause the 2572-B module to restart with the CTI
factory default address described above.
Instead of manually setting a static address, you can cause your PC to generate a compatible address, if your PC is
using DHCP (Dynamic Host Configuration Protocol) to obtain an IP address.
The IP address 169.254.1.1 is a link local IP address, which is used only to communicate on the local network. When a
Windows PC is unable to obtain an IP address from DHCP, it automatically generates a link local address using a
feature called Automatic Private IP Addressing. To cause the PC to generate a compatible address, do the following:
•
Connect an Ethernet cable directly between your PC and the 2572-B module;
•
Reboot the PC.
NOTE: It may take several minutes before the PC will stop trying to contact a DHCP server and generate the Link Local
address.
You can display the IP parameters being used by the PC by opening the Command Prompt window and
entering IPCONFIG at the prompt. Once the link local IP address is generated, you can connect by typing
