2.2b Use DIP Switches
When using the DIP switches, a switch in its ON position represents a logic ‘1’. Physically, the switch is
pushed “up” towards the transducer connectors. A logic ‘0’ is when the switch is in its OFF position, (pushed
down).
When all of the DIP switches are in their logic ‘1’ position, (ON), the NX2A4E2 will use the IP address it has
stored in flash memory. When all of the switches are in their logic ‘0’ position, (OFF), the NX2A4E2 will
start searching for a DHCP server on power up.
The DHCP client is included to meet the ODVA requirements for EtherNet/IP. It is not
a suggested method for setting the IP address on a NX2A4E2. If your system requires
you to use DHCP, contact AMCI Tech Support for assistance.
When the eight DP switches are set to any other ON/OFF combination, these switches set the lowest octant of
the IP address.

When using this method the upper three octets of the address are locked to ‘192.168.0’.

Because of its mounting, switch 1, which is the closest to Port 2, is the Most Significant Bit . Switch 8,
which is closest to the Status LED’s, is the Least Significant Bit .
As an example, ‘50’ equals ‘0011 0010’ in binary. To program this value into the NX2A4E2, set switches 3,
4, 7 to their ON position, and all other switches to their OFF position.
