eI/O Manual 26
Problem: The eI/O module starts up with a strange IP address (i.e., 192.168.42.253).
All eI/O modules are shipped with enabled static IP address of 192.168.42.253. Also if the device is
set to DHCP, and no DHCP server is available or the DHCP server cannot be reached, eI/O modules
default to an IP address of 192.168.42.253. Change the PC‟s network settings to place both the
eI/O module and PC on the same subnet. Adjust the eI/O module‟s IP address and Netmask using
the Ethernet Config utility (Start  All Programs  Sealevel Systems  SeaMAX  Ethernet
Configuration Tool) installed with SeaMAX. Then restore the PC‟s network settings.
Problem: The eI/O module is visible in Ethernet Config, but the network settings cannot be
changed.
The eI/O module is most likely on a different subnet than the PC. The PC‟s IP address and Netmask
must be altered to place both the eI/O module and the PC within the same subnet. Contact your
network administrator for assistance.
Problem: The eI/O module doesn’t show up in Ethernet Config.
eI/O modules are discovered via a UDP broadcast. Verify that any firewall software, such as
Windows Firewall, ZoneAlarm, etc., or router settings that would hinder UDP transmissions are
disabled.
It is also possible that the eI/O module may not be discovered if the PC and module are on separate
subnets. This may occur if the module‟s IP address is configured outside the range of the PC‟s
subnet. It can also occur during a failed DHCP discovery. In either case, the “Recover Module”
button in Ethernet Config utility may be used to recover the device. Refer to the Hardware
Configuration section of this manual for more information.
