Overriding a Network Configuration
The NIU can also be configured via a message from the network. A network
configuration can be set up to deliberately disable the auto-configuration function.
If autoconfiguration has previously been disabled by a network configuration, you
can restore the autoconfiguration function by following the steps below.
1. Set the upper SBA select switch (SBAx10) on the NIU to the A position.

2. Cycle power.
3. Reset the upper SBA switch to select the tens digit of the SBA.
4. Cycle power again.
Changing the SBA to a normal SBA does not disable autoconfiguration again. Once
autoconfiguration has been enabled, it cannot be disabled manually. A configuration
message sent to the NIU over the network or from the Remote I/O Manager
configuration tool disables autoconfiguration.
Reenabling Network Configuration
To reenable a network configuration that has been overridden as described above:
1. Set the SBA select switches on the NIU to a valid address between 0 and 31.
2. Cycle power.
Upgrading the NIU Firmware
1 . Connect the cable (IC200CBL002) from the programming device to the port
on the lefthand side of the NIU.
2 . Set the upper switch (SBAx10) to the U (Upload) position.
