CIDR notation (routing prefix) is related to network mask that is also necessary in order to
manage CFIP unit. The IP address of your PC Ethernet adapter and CFIP unit should be from the same
subnet in order to manage the CFIP unit. In the table below some examples are given for CIDR
notation and subnet mask relation.
CIDR notation
Network mask
/24
255.255.255.0
/25
255.255.255.128
/26
255.255.255.192
/27
255.255.255.224
/28

8.2.2
Discovery of IP Address and Firmware Version in Case The Subnet of CFIP
Unit is Known
For this purpose the command “dp scan <local_addr> <scan_addr>” should be executed in
‘cmd’. Instead of <local_addr> place the IP address of your PC Ethernet adapter that is connected to
CFIP unit and instead of <scan_addr> place the broadcast address of specified subnet. Refer to
Figure
8.2
for example.
(!)
Note that IP addresses of Ethernet adapter and CFIP units may belong to different subnets. This
command sends discovery messages on broadcast address 255.255.255.255 to all devices in network.
All CFIP devices connected to this network are responding with its own IP address/CIDR notation and
firmware version.
