PCAN-Ethernet Gateway DR – User Manual

255.255.255.0 and the network address 192.168.1.xxx, the
reserved address would be: 192.168.1.255
Depending on the Subnet mask the lowest device address is
reserved for messages that are addressed to the entire network.
For the Subnet mask 255.255.255.0 and the network address
192.168.1.xxx, the reserved address would be: 192.168.1.0
Subnet mask:
The Subnet mask indicates which part of the IP
address represents the network, and which part represents the
device. This subdivision is achieved by filling in the (binary) Subnet
mask from left to right with the number “1”. The resulting values
for the individual fields are: 0, 128, 192, 224, 240, 248, 252, 254 and
255.
While entering values from left to right, as soon as a value smaller
than “255” is entered, a “0” must follow. For example 255.255.128.0
is valid, while 255.128.255.0 is false.
Gateway:
Enter the IP address (IPv4) of the gateway that manages
the IP network. Proceed with the same guidelines as outlined for
local IP address entry. Entering a gateway address is optional.
Note:
Please note that after modifying these settings, the de-
vice may not be reachable. Possible causes for this are:
–
You activated DHCP. The IP address of the device is not
known because it has been acquired dynamically from the
gateway. The address can often be found on a list provided
by the gateway.
–
You have changed the part of the address assigned to the
network (see Subnet mask information). In this case the
device is now part of a different network than the one your
computer is a part of. Connecting to the device is only
possible by respectively adapting your computer’s IP
address to the different network that the device is in.
