eI/O Manual 28
An eI/O module may become no longer visible in the module list in the Ethernet Config utility if
the eI/O module has been configured to use a different subnet than the host computer.
In other cases, the eI/O module doesn‟t appear in the module list due to a DHCP discovery
failure. In either case, clicking on the “Recover Module” button (see image on previous page) in
the Ethernet Config utility will bring up the “Module Reset” window shown below.
Before recovery begins, make certain that the PC and eI/O module are on the same network
segment – they should be connected with an Ethernet crossover cable, through a hub, or
through a non-routing switch. eI/O modules are shipped with an Ethernet patch cable (blue).
Next, select the IP Address of the network card your device is connected to from the dropdown
labeled “Network Interface.”
Enter the MAC address found on the label on the bottom of the eI/O enclosure. A MAC address
is made up of six pairs of hex digits separated by dashes (i.e., xx-xx-xx-xx-xx-xx). While
entering the MAC address, the indicator to the right of the field will turn red if the MAC address
entered is invalid. Once a MAC address is successfully entered, the indicator light will turn
green and the “Network Settings” options will be enabled.
Contact your network administrator if you are unsure of the proper network settings to choose.
If a DHCP server is available, select the “Enable DHCP Configuration” checkbox. Otherwise,
complete the network settings and click the “Recover Module” button to complete the
configuration changes.
