When switch 9 is ON and other DIP switches are:
0 – Static IP:
hardcoded IP address of 192.168.1.254
1 – DHCP:
Pulls IP address from DHCP server
2 – NV Static:
Full address taken from device Non-Volatile
Memory (static)
3 – NV DHCP:
Addresses are taken from the DHCP server
and assigned to device NV memory. To keep this address as
static, power down the device and then change DIP Switch
setting to 2 (NV Static) before re-powering the device
4 – Internal IP Address Allocation Method:
Device
disregards DIP Switch selections and IP configuration is done
via
in
Control software by setting parameter “IP ADDRESS
ALLOCATION METHOD.” The available settings for this
parameter are the same as settings 0 through 3 available via
DIP Switches. Setting 3 NV DHCP allows devices to get
addresses from DHCP and assigns them to NV memory.
Next, setting the parameter to 2 in the software before
power cycle will allow devices to retain the last active IP
addresses as static without having to physically change DIP
Switches on each device.
The DIP Switches are used to configure the IP address for
the Ethernet port. Even though there are two Ethernet ports
on the Ethernet Option card, these ports act as a two port
switch and both have the same IP address. This allows
multiple C445 Ethernet Cards to be daisy-chained rather than
each being connected to the same switch or switches. It also
provides for the capability of connecting in a redundant ring
topology when connected through switches that support this
technology.
