Configuring the Encoder for Your EtherNet/IP Network
Assigning the IP Address Using BOOTP/DHCP:
Verify that the encoder MAC ID is in the relationship list in the BOOTP
Utility or DHCP server before attempting to assign the encoder an IP address.
1. Set the three network address switches to 999 and cycle power.
2. Set the three network address switches to 000 and cycle power.
3. The encoder powers up and request an IP address from a BOOTP/
DHCP server.
4. If the encoder MAC ID is in the relationship list, the BOOTP/DHCP
server assigns the associated IP address to the corresponding MAC ID.

001…254
Sets last octet of the IP address to the value indicated (xxx in 192.168.1.xxx)
888
Restores all factory default settings in the encoder and clears its IP address
999
Clears the encoder IP address

ATTENTION:
Disable DHCP after the new network address is set (see next
step).
When the DHCP is disabled, it prevents unexpected resetting of the network
address, which could result in unintended machine motion or loss of process
control.
